Scott Bessent had a busy Monday.

The U.S. Treasury Secretary was in Paris. G7 finance ministers were meeting, as they do, to coordinate the West’s economic pressure on its adversaries. Bessent had two items for the press. The first: Washington was extending, for the third time in three months, its emergency waiver allowing the purchase of Russian oil alr…

On May 11, Indonesian Energy Minister Bahlil Lahadalia told reporters in Jakarta that contracts for 150 million barrels of Russian crude had been signed and the first cargo was expected within two weeks. “The deal is done,” he said. “The contract is done.” Five days later, the U.S. Treasury’s emergency authorization permitting buyers anywhere in the world to purchase sanctioned Russian oil technically lapsed.

The waiver, first issued on March 12 after the Strait of Hormuz crisis disrupted Gulf shipping and sent oil prices soaring, was intended as a temporary emergency measure to stabilize stressed energy markets. But even after Treasury Secretary Scott Bessent signaled on May 16 that Washington intended to tighten pressure on Moscow, the administration again reversed course, extending the authorization through May 16.

By then, the market had already begun reorganizing around the assumption that discounted Russian crude would remain available. Indonesia’s decision to enter the Russian oil market at scale is the most significant and visible signal of that reorganization. It is one of at least four deals concluded with Asian buyers during the waiver period, bringing the confirmed aggregate committed volume to approximately 153.7 million barrels: Indonesia’s 150 million barrels, the Philippines’ 2.48 million barrels procured by Petron in late March, and two shipments of an estimated 600,000 barrels each for a total of 1.2 million delivered by a sanctioned Russian shadow tanker to two Japanese refineries under direction from Japan’s Ministry of Economy, Trade and Industry (METI) in the first two weeks of May. Singapore and Hong Kong were separately confirmed as new buyer destinations by the Centre for Research on Energy and Clean Air (CREA) — almost certainly trading entities taking positions for re-export rather than refinery intake, and with no disclosed volumes.

Taken together, these deals represent the normalization of trade in sanctioned Russian crude beyond the original buyer pool of China and India. Indonesia had not openly purchased Russian oil at this scale before and had largely relied on shadow-fleet ship-to-ship transfers near Hong Kong to avoid blowback. Japan, meanwhile, had avoided Russian crude imports since June 2025 except for narrowly tailored sanctions exemptions tied to Sakhalin-2, the Far East energy project Tokyo considers strategically necessary for LNG supply security. All three countries did so during the same 65-day window, under the same authorization. Japan’s government is now reportedly sending an official delegation to Moscow to discuss, among other things, expanding that relationship further.

Tokyo–Washington’s closest Indo-Pacific ally–has said there has been no change in its cooperative stance on sanctions against Russia. But recent moves to organize government and business delegations to Moscow, including participation by some of Japan’s largest trading houses and at least one Japanese legislator, hint at growing unease inside parts of Japan’s business and political establishment over the long-term costs of economic disengagement. For a G7 coalition already divided over price caps, waivers, and maritime enforcement, that is not a trivial signal.

What began for Moscow as an emergency workaround after the G7 imposed an oil price cap on Russian oil in late 2022, and the adoption of sectoral sanctions on Russia’s energy, finance, and defense-industrial base, is evolving into a durable parallel trading system with its own logistics, brokers, financing channels, and political logic. Powered by a fleet of hundreds of aging tankers with dodgy paperwork and histories that link them to the sanctioned Iranian oil trade, the shadow economy that has grown up around Russian trade is now also consolidating a parallel energy-financial architecture built around shadow shipping, ruble-yuan settlement, offshore liquidity networks, and sanctions-adapted payment channels operating increasingly outside the Western financial system.

Figure 1-This chart shows the flows of Russian oil to Asia during the period when the Treasury waiver was in force from March 12 to May 16. During that 65-day stretch amid the Strait of Hormuz closure Russian tankers delivered an estimated 1.8 to 2.25 billion barrels a day, roughly half that was borne by the shadow fleet. Sources: Kpler, Vortexa, US Treasury, WTO Hormuz Trade Tracker.

The Treasury authorization was a 65-day experiment in managed contradiction — designed as emergency triage after U.S. and Israeli strikes on Iran in late February closed the Strait of Hormuz, the narrow waterway through which roughly a fifth of the world’s oil normally passes, and sent prices toward $120 a barrel. The idea was to let stranded Russian crude clear the market and wind down. What it produced instead was more durable: state-level supply commitments from major Asian economies that will endure despite sanctions, an accelerating reorganization of Russia’s shadow shipping fleet under naval protection, and financial infrastructure that Washington was simultaneously trying to dismantle even as the Trump administration licensed its operations.

The expiration date for the extension came and went over the weekend without any official update from Treasury’s Office of Foreign Asset Control (OFAC). But after two successive reversals amid energy-market stress, traders and intermediaries increasingly appeared to view the waiver regime less as a temporary emergency measure than as a rolling feature of the market. On Monday, May 18, Bessent confirmed that assumption, announcing another 30 day extension for Russian oil sales that will expire in mid-June.

Whether Treasury blows through a third expiration date and extends again, may now well be beside the point. With Trump now reportedly considering reversing separate designations levied against Chinese teapot refineries in connection with sanctioned Iranian oil trade Washington is clearly wrestling with the loss of leverage in its employment of chokepoint statecraft. The fact is that the shadow fleet and the financial infrastructure the Kremlin has built to prop up its oil trade and fund its war in Ukraine are entrenching the bifurcation of the world energy market, at the risk of normalizing parallel settlement systems that reduce Western visibility into, and leverage over, the global energy trade.

A Stanford University research team estimated in a study released just days before the authorization expired that extending the waiver through December 2026 would generate an additional $36.1 billion in Russian oil revenues, equivalent to roughly 2 percent of Russia’s entire economy. The administration has not publicly addressed the estimate. But for buyers such as Indonesia, the market appears to have already moved on. Discounted Russian crude and the shadow infrastructure supporting it are increasingly being treated not as temporary wartime expedients, but as enduring features of global energy commerce.

That has serious implications for a negotiated settlement in Ukraine — and for any Western government still counting on sanctions pressure to shape Moscow’s calculus at the table. Whether Washington extends the waiver or not, five things are now true that were not true on March 12. First, there are the earnings. While the surge in oil revenue has not reversed the downward trend of the Russian economy it will make it possible for the Kremlin to plug holes in its budget. Second, the shadow fleet is growing its customer base. The hurt for in Asia for oil poses an existential threat for some countries in the region, and it is fast eroding compliance with sanctions regimes. Third, the revival of the shadow trade is turbocharging Russia’s digital payment settlement system, puffing up Vladimir Putin’s dream of converting the ruble into a fulcrum against dollar dominance and enhancing Russia’s share of the BRICS trade. The fourth is linked to the first three; the turn toward ruble-yuan trade obscures structural weaknesses in an economy aptly characterized by CSIS as crashing after a “sugar high” of increased defense-industrial spending and subsidies. That opacity is appears to be clouding the Kremlin’s judgment about the country’s capacity to absorb more economic pain as the war drags on. Lastly--and perhaps least appreciated in Washington--is that the shadow trade system is incentivizing greater cooperation between gray zone entrepreneurs who keep supply lines to Russia and Iran humming. That is a feature likely to endure and harden in the emerging new world order.

The argument against another extension is not about oil prices. It is about what the first two authorizations built while everyone was watching the price, and why each of those five things makes the next extension harder to justify on its own terms. All five trend-lines lead back to the same Russian financial house–Promsvyazbank, or PSB as its better known in Moscow, and its companion digital currency enterprise A7. A fuller breakdown of the first two trends--renewed earning power and a growing client list--follows with a detailed explanation of the others elaborated on in the second part of this analysis.

1. What Russia Earned

The windfall is real, but Ukraine’s steadily escalating campaign of attacks on Russian energy infrastructure have muted its effect on the Kremlin’s government budget. Russia’s fossil fuel export revenues reached 734 million Euros per day in April 2026 — the highest level in two and a half years, according to CREA’s April monthly tracker. Urals crude was trading at $112.3 per barrel, more than double the $44.10 ceiling that the European Union and the United Kingdom had set to limit Russia’s war revenues. The G7’s original $60 ceiling, still nominally in force on the U.S. side, had become a figure nobody enforced.

Ukraine’s drone campaign was the one mechanism that actually dented volumes. Repeated strikes on the Tuapse refinery — Russia’s fifth-largest oil export installation — contributed to a 65 percent year-on-year drop in oil product export volumes between January and April, per CREA. Baltic port loading at Ust-Luga and Primorsk halved in late March after Ukrainian drone strikes hit both terminals. For a period, roughly 40 percent of Russia’s oil export capacity was offline.

The Urals price premium offset most of the damage. Russia’s Finance Ministry reported that oil and gas revenues fell 38.3 percent year-on-year through the first four months of 2026. Deputy Finance Minister Sergei Aleksashenko said that much of the windfall was consumed by a “war premium” of roughly $2.95 billion in subsidies to oil companies for domestic fuel price suppression, not the war budget directly. There are no precise estimates for the cost of repairs to damaged infrastructure and continued Ukrainian strikes on shadow fleet tankers, but the number could stretch will into the hundreds of millions, if not several billion. Complicating the picture further is the Rube Goldberg like system of subsidies and regional debt cancellations, the Kremlin has enacted since the start of the war to stabilize the economy.

That said, the oil revenue surge has coincided with a fundamental shift in how Russian crude is paid for. By January 2024 — the last point at which Russia’s central bank published a breakdown — yuan accounted for 34.5 percent of Russian export settlements, up from less than one percent before the invasion, CBR Governor Nabiullina told RIA Novosti. A large part of the infrastructure now routing those payments is predominantly powered by PSB and its digital payments platform A7, and operates almost entirely outside the Western banking system.

1. Who Is Now Buying, Who Is Hedging

Buyers in the first weeks of the authorization produced were opportunistic. The Philippines, Singapore, and Hong Kong made emergency spot purchases — supply disrupted, gap filled, no long-term commitment entered. South Korea also joined the club with an emergency purchase of Russian naphtha. The second period, which ran from April 15 to May 16, produced something different.

Pertamina, Indonesia’s state energy company, entered 2025 committed to buying Russian oil only at or below the $60 price ceiling. That position is gone. An April 13 Kremlin meeting between Indonesian President Prabowo Subianto and Russia’s President Vladimir Putin produced a supply deal running through the end of 2026, with Russia committing to build oil storage facilities in Indonesia and explore refinery development alongside it. Bahlil confirmed contracts were signed on May 11 but declined to disclose the pricing, the currency, or the banking channel. A separate Indonesian official said the same day that ministries were still discussing which import channels would be used. The contracts were signed. The transaction architecture was not settled.

Japan moved faster and more explicitly.The first Russian oil cargo to reach a Japanese refinery since June 2025 arrived on the Omani-flagged and sanctioned Voyager tanker at a Taiyo Oil facility in western Japan on May 4-5, sourced from Sakhalin-2, the Pacific offshore project in which Japanese companies hold equity stakes. Japanese authorities initiated a subsequent purchase that was routed to a second refinery.

Voyager’s registered owner, Marvel Marine, is linked to Dreamer Shipmanagement LLC-FZ, one of several Dubai free zone-registered shadow fleet intermediaries that shares an address at the Meydan Grandstand business center and links to Russia’s state shipping giant Sovcomflot. The tanker departed Prigorodnoye on March 1, 2026 — eleven days before the Treasury Department issued the waiver via General License 134. The vessel loaded before the waiver opened. By Day 5 it was already transiting the China Coast at 94 percent laden, according to AIS snapshots collected and analyzed by Frontline Atlas during the first stage of the waiver period. The draught held at 12.7m through Day 33, and the destination remained OPL Hong Kong across four consecutive snapshots, suggesting a lightering or STS transfer rather than a direct port call.

There is no word on whether Japan was aware of the ship’s complex history. But METI officials are reportedly slated to travel to Moscow on May 26-27, but the diplomatic trip, which will include representatives from Mitsui and Mitsubishi, is ostensibly focused on the protection of Japanese assets in Ukraine and post-conflict economic cooperation.

Singapore and Hong Kong purchases of Russian oil during the waiver period appear to be mostly contingent ship-to-ship transfers, but the transactions have likely been settled in yuan. Both Indonesia and Japan have declined to explain how they intend to pay.

China’s appetite for Russian crude shows no signs of slowing. Nor does India’s. Officially, the government has signaled it will return to the status quo of buying oil at the price cap threshold assuming no extension is forthcoming. But its recent request to the Trump administration to extend the waiver for a third time suggests India is hedging and hoping for a different outcome. The stance has started to roil politics in New Delhi. India’s Congress opposition party leadership has slammed the ruling BJP party of President Narendra Modi for “begging” Washington for “permission” to import Russian oil and “handing over” India’s “energy sovereignty” to Washington.

Russia’s biggest buyers, China and India, have, meanwhile, been much more open about their high-volume oil transactions and their drive to settle trade with Russia outside the dollar system. Kpler data indicates that approximately 30 million barrels of Russian crude were destined for China in mid-March, with seaborne imports averaging 1.82 million barrels per dayin March and 1.92 million into April. Indian refiners imported nearly 60 million barrels of Russian crude during the initial waiver period. Following the Treasury extension, imports surged to a record high of 2.3 million barrels per day in the first half of May, a milestone recently celebrated by Russia’s foreign minister Sergei Lavrov.

Russia’s trade with its two largest Asian oil customers is now overwhelmingly moving outside the dollar system. The vast majority—estimated at over 90 percent—of the bilateral trade operations between India and Russia, predominantly driven by crude oil imports, is now settled outside the US dollar system. Putin said in December 2025 that national currencies accounted for 96 percent of Russia-India commercial settlements, while Russia’s finance minister said 99.1 percent of Russia-China settlements were conducted in rubles and yuan. Separately, Russia’s Energy Ministry documents reportedly put the yuan’s share of Russian oil and petroleum-product payments at 67 percent, with the dollar down to 5 percent, Izvestia reports. Russia-China trade dipped in 2025, but the payments architecture remained: ruble-yuan settlement had become the default, not the exception.

What those settlement figures do not show is the full architecture routing the payments — who built it, who controls it, and what else moves through it alongside Russian crude. Earlier this year, a Moscow company called A7-Agent posted part of the answer to its own website. Another part of the answer runs through balance sheets for PSB, the Russian state bank whose statutory mandate covers every defense contract in the country.

Behind those supply relationships, the financial and logistical infrastructure that made them possible kept operating throughout the 65-day window — and is still operating now. That infrastructure is the subject of a forthcoming Part 2.

The price of oil crossed $100 a barrel the week Iranian tankers sailed through the U.S. naval blockade of the Strait of Hormuz. Into that moment, Washington and Brussels each launched a major enforcement action against the financial architecture keeping sanctioned oil moving to market. The Trump administration targeted Iran. The EU targeted Russia. On April 23, for the first time, two major Western enforcement actions hit the same underlying architecture from different directions on the same day — the shadow fleet vessels, UAE-based brokers, and Tron-based cryptocurrency rails that Tehran and Moscow have spent years assembling to move sanctioned oil and settle payments beyond the reach of SWIFT and U.S. Treasury enforcement.

Under Operation Economic Fury, the Trump administration’s campaign to cut off Iran’s financial lifelines by targeting the vessels, brokers, and buyers moving its sanctioned oil to market, OFAC has sanctioned more than 1,000 Iran-related persons, vessels, and aircraft since February 2025. The EU’s 20th sanctions package was the bloc’s largest single designation round in two years — 120 new listings across vessels, banks, energy companies, and for the first time a Russian-linked private military security contractor. Neither government has broken the system both are targeting. Both are pressing harder on it.

The China signal

The sharpest signal in Operation Economic Fury’s opening round was the decision to sanction a Chinese industrial anchor.

Treasury’s designation of Hengli Petrochemical, China’s second-largest independent oil refinery, documents billions of dollars in Iranian petroleum purchases, with deliveries overseen by Sepehr Energy Jahan Nama Pars, the oil sales arm of Iran’s Armed Forces General Staff. Hengli is a major industrial anchor in China’s refining sector. Every Chinese financial institution processing its payments now operates under secondary sanctions exposure. The vessel designations in the same action named the Panama-flagged Lisboa, which transported over 2.5 million barrels of Iranian naphtha to the UAE between July 2025 and January 2026, and the Hong Kong-flagged Lynn, which conducted ship-to-ship transfers of Iranian crude off Malaysia before delivering to China.

The designation lands at a specific moment. Since Iran closed the Strait of Hormuz in late February, Tehran has conditioned passage through the strait on yuan-denominated oil sales rather than dollar settlement — an explicit challenge to the petrodollar architecture at its most vulnerable point, documented by CNN and confirmed by a senior Iranian official. The Atlantic Council’s analysis of Tehran’s payment architecture documents yuan settlements as the primary active channel for Iranian oil revenue, with USDT — the dollar-denominated digital currency also known as Tether — and other dollar-adjacent instruments handling residual broker payments and reserve storage. Sanctioning the refinery processing that crude puts a price on Beijing’s tolerance for the arrangement. The Hengli designation is the statement of intent. The follow-through is what determines whether it is a warning or a bluff.

The EU’s instrument problem

Washington’s pressure on Beijing over Iranian crude is running in parallel with Brussels’ effort to squeeze Moscow — but the EU is working with a different set of tools, and the sharpest one is still sheathed.

The EU’s 20th sanctions package passed on April 23 because Hungary dropped its veto. Budapest had blocked it since February, withholding support until Ukraine restored oil flows through the Druzhba pipeline. The 46 newly designated vessels bring the EU’s total shadow fleet blacklist to 632 ships — and widen the enforcement gap between Brussels and Washington that Frontline Atlas documented last week. The EU designated 509 vessels in 2025. The United States designated 191 in a sprint before January 20, 2025, then stopped.

What the 20th package added is significant. Transaction bans on 20 Russian banks and four foreign enablers closed corridors Russian energy traders used to settle payments outside SWIFT. The package designated the Karimun Oil Terminal in Indonesia — the first time the EU has sanctioned a third-country port. It banned the entire Russian crypto services sector and designated Moran Security Group, the Wagner Group and Kremlin-linked firm whose armed personnel have been seen aboard sanctioned tankers photographing NATO coastlines.

The maritime services ban — prohibiting European companies from insuring, financing, and managing shadow fleet tankers — appeared as legal groundwork only. Greece and Malta pressed for G7 consensus first. That consensus does not exist. As of February 2026, 111 designated vessels continued loading Russian oil cargoes despite appearing on the blacklist. Kaja Kallas announced the 21st package was already in preparation. Until the maritime services ban takes effect, the shadow fleet faces higher operating costs. It does not face an existential threat.

One network, two flags

The enforcement gap is real. So is what both campaigns keep finding on the other side of it: China and India sit at the center of both networks. India buys sanctioned Russian and Iranian crude at scale too. But for Beijing the trade carries a second logic. Every yuan-settled oil transaction advances China’s long-term project of building payment infrastructure that routes around the dollar system. Tehran’s decision to condition Strait passage on yuan settlement handed Beijing a live test of that infrastructure under maximum market stress. It held.

The clearest evidence of the shared network sits in Treasury’s own designation files. Mohammad Hossein Shamkhani ran a UAE-centered shipping empire that moved Iranian and Russian crude through the same front companies to the same Chinese buyers. The EU designated him in July 2025 under its Russia sanctions package. OFAC designated him the same month under Iran sanctions. Same man. Same UAE companies. Same China-bound tankers. The April 2026 follow-on action found that Fleet Tanqo Private Limited, an Indian firm in the Shamkhani network, transported Russian oil through the same structure simultaneously running Iranian crude to China.

The pattern holds from the Russian end. As Frontline Atlas revealed last week, the Baransky-Shor network settles shadow fleet transactions through Promsvyazbank’s A7 platform — the same Tron-based USDT rails the Shamkhani network runs on. The vessel-level evidence is direct: Promsvyazbank operated the Veronica, a tanker with prior documented ties to an IRGC-linked network, before it moved into the Baransky fleet. A7A5 processed $93.3 billion in transactions in ten months before the EU designated it. When authorities seized Garantex, its operators launched Grinex within months using A7A5 as the financial bridge. The EU’s sectoral crypto ban targets that cycle directly.

Two networks. One set of rails.

The Tron question

The frozen wallets connect directly to the shared infrastructure the vessel designations were targeting. Both Iran and Russia settled sanctioned oil payments on the same blockchain for the same reason.

Both need dollars — or something that functions like dollars — to settle international commodity trades, pay brokers, and store reserves. Neither can access the dollar system directly. USDT on Tron — the blockchain network that now carries roughly $85 billion in dollar-denominated digital currency — gives both an instrument that settles instantly, moves across borders without correspondent banking, and sits outside SWIFT and U.S. Treasury’s direct reach. Iran used it to park central bank reserves. Russia used it through A7A5 and Garantex to move cross-border payments. The instrument is the same because the problem is the same.

Iran built the infrastructure first. Seven years of sanctions pressure drove Tehran’s intermediaries toward Tron-based USDT as the closest functional equivalent to a dollar that exists beyond SWIFT’s reach. Russia adopted what was already operational after 2022. Each successive wave of designations pushed more actors onto the same rails, deepening liquidity and reinforcing the network effect that makes Tron-based USDT the dominant settlement instrument for sanctioned oil payments, as TRM Labs notes. TRM Labs found that one frozen wallet carried no outbound transfers at all. The other moved less than $16 million out against more than $228 million in. Accumulation concluded by late 2023.

Iran’s central bank was parking dollar reserves on a public blockchain because it had nowhere else to put them. OFAC found it. That is the measure of how thoroughly the dollar system has been rebuilt in miniature on Tron — and how exposed that reconstruction becomes when the ledger is public.

The harder you press, the deeper it goes

The Tron architecture hardened under Western enforcement pressure — and the same dynamic is playing out across the entire shadow system.

Three years of Western sanctions have not shrunk the shadow fleet. They have consolidated it. Each successive wave of designations pushes more vessels, brokers, and payment platforms out of the regulated system and into shared infrastructure that becomes more resilient the more it is pressed. Iran built the evasion architecture under maximum pressure from 2018 onward. Russia adopted it after 2022. Venezuela was already running through it. The Shamkhani network exists because simultaneous sanctions pressure on two major oil exporters created demand for a broker who could serve both. The Baransky-Shor cluster absorbed vessels cycling out of IRGC-linked networks after Trump’s first term designated them. A7A5 emerged after Garantex was seized. Grinex emerged after A7A5 was designated.

The April 23 actions are the most ambitious single-day enforcement effort of the conflict period. The EU went after the ecosystem rather than individual exchanges for the first time. OFAC froze sovereign reserves, not operational wallets. Both are meaningful escalations. Neither changes the underlying dynamic: as long as China buys Iranian crude, India buys Russian crude, and the maritime services ban waits on G7 consensus that Washington is not building, the shadow system has a market. Markets find infrastructure. This one already has it.

The foggy way ahead

Taken together, the consolidation of shared infrastructure, the Tron payment rails, and the limits of the EU’s enforcement toolkit point toward a harder question: whether Western sanctions can squeeze adversary oil revenues without accelerating the shift away from the dollar-denominated system those revenues flow through.

The shadow system Iran and Russia have built is dollar substitution at the margins. The Bank for International Settlements found the dollar on one side of 89.2 percent of all foreign exchange transactions in April 2025 — up from 88.4 percent in 2022, the same period the shadow system was scaling rapidly. The petrodollar has absorbed the pressure. It is bending. It is not breaking.

What is being built is more specific and more durable than de-dollarization narratives suggest. The shadow fleet is the logistics layer. The Tron network and CIPS are the payment layer. Together they constitute a workaround, and workarounds, once built, tend to get used for more than their original purpose. Washington knows this. The Hengli designation and the $344 million freeze are attempts to close the gap before it widens. Whether they succeed depends on whether China blinks. So far it has not had to.

Whether Washington can ram through a rewiring of the global energy market amid two active theaters of war and across a transatlantic relationship already under strain, is the open question the April 23 actions leave unanswered

.

The ship unloaded at Vadinar, home to one of India’s largest oil refineries, one the European Union and United Kingdom had sanctioned for its ties to Rosneft, Russia’s state oil giant. The delivery arrived just four days after the United States issued a waiver suspending sanctions on Russian oil to stabilize energy markets shaken by the crisis in the Strait of Hormuz.

The Cavalier is designated by five Western governments as a sanctions evader. So is the cargo it carried, Russian crude loaded at a Baltic terminal and tracked across the Suez Canal to Vadinar. So is Nayara Energy, the refinery company that operates at the Indian port. The United States, the European Union, and the United Kingdom had spent years trying to cut off the money financing Russia’s war in Ukraine. Block the ships, the insurance, and the buyers, and strangle the revenue.

The Cavalier docked anyway. It was not alone. While the Strait of Hormuz crisis dominated headlines, Russia’s sanctioned tanker fleet was quietly moving oil. A Frontline Atlas investigation tracked 186 of those vessels across the 30-day waiver window. A little more than two-thirds completed at least one delivery while U.S. Treasury Department restrictions were suspended. Fifty-one vessels carried sanctions from five or more governments. Five tankers had previously carried security personnel with documented ties to Russian military and intelligence organizations. They delivered anyway.

The Cavalier and its peers are only a slice of a much larger system of hundred of so-called “shadow” vessels operating outside the Western-regulated shipping system without Western insurance, recognized registration, or legal accountability. A Frontline Atlas analysis of 1,931 designated tankers shows the same shell companies, flag registries, and financial intermediaries moving Russian oil also surface in networks sanctioned for moving Iranian and Venezuelan crude. Pressure on one corridor does not stop the flows. It reroutes them.

The waiver worked exactly as Washington intended. Russian crude in floating storage fell from 125.1 million barrels on March 4 to 99.3 million barrels by April 2, according to a recent S&P Global analysis. Deliveries hit their highest on record since 2023, with India importing most of it. Shipping companies based in wealthy G7 nations delivered about 30 percent of stranded Russian oil. But it was shadow fleet tankers that captured most of the upside, moving the volumes that formal operators would not touch weeks earlier.

The money at stake is not abstract for Moscow. Before the U.S.-Israeli strikes on Iran, Russia was earning an estimated €470–€500 million per day from fossil fuel exports, according to the Centre for Research on Energy and Clean Air (CREA), a Helsinki-based research organization. In the two weeks that followed the opening salvos as energy markets reeled, daily revenues climbed above €510 million, producing €6–€7.7 billion in total and underscoring how quickly the system scales when prices rise. More than half of those earnings came from oil deliveries borne on sanctioned Russian shadow fleet vessels and ships suspected of skirting the G7 oil price cap, according to a recent CREA analysis.

Before the conflict in the Persian Gulf, the outlook for Russia’s shadow fleet was deteriorating. Tens of millions of barrels of crude sat stranded at sea. Tankers idled for weeks under a sanctions regime that had finally begun to bite. Hundreds of sanctioned vessels were waiting for buyers that were not coming. New Western restrictions on Rosneft and Lukoil, two of Russia’s largest oil producers, had abruptly disrupted exports. Seaborne crude sold by the two firms fell by a little more than 80 percent year on year in the months following the sanctions. India, one of the largest buyers of Russian seaborne crude, sharply reduced Rosneft shipments in January after the Trump administration warned the U.S. would sanction third-party buyers of Russian oil.

For a brief window in early 2026, it began to look, for the first time, as if Western governments might be getting serious about squeezing Russia’s oil revenues and constraining its shadow fleet. European and British authorities stepped up enforcement actions against suspect tankers, and policymakers in Brussels and London moved to push the oil price cap below the original $60 threshold agreed on by G7 countries in 2022.

Four years on since Russia’s full-scale invasion of Ukraine, several EU countries had concluded that Russia’s shadow fleet was doing more than moving oil. In September 2025, drones repeatedly closed Copenhagen Airport and other Danish facilities in what Prime Minister Mette Frederiksen called the “most serious attack on Danish critical infrastructure” to date. Danish authorities identified three tankers with Russian links — including the Pushpa, which also sails under the name Boracay — as possible launch platforms, noting the vessel had skirted Danish coastal waters around the time of the overflights.

France detained the Boracay the following October off its Atlantic coast and boarded the Grinch in the Mediterranean in January with British intelligence support. When French authorities boarded it, they found two employees of Moran Security Group, a Russian private military security company with well-documented ties to the Wagner Group, the Kremlin’s notorious mercenary army. French authorities said the vessel’s security personnel were tasked with monitoring the crew and gathering intelligence, and one of the two captured was a former Wagner operative.

An investigation published in March 2026 by the Organized Crime and Corruption Reporting Project, OCCRP, documented a systematic pattern of Wagner Group and Russian military intelligence veterans deployed as security supernumeraries aboard shadow fleet tankers departing Baltic ports — vessel protection teams designed, European intelligence officials said, to raise the cost of any boarding operation. A Frontline Atlas cross-check of the Wagner operatives named against a proprietary database of more than 60,000 Wagner and Russian paramilitary personnel records independently confirmed the service histories of several of the individuals identified. That database has informed Western sanctions designations, a war crimes prosecution in Finland, as well as trials for convicted saboteurs and covert operatives linked to Wagner in Poland and the UK.

Prosecutors in France ultimately convicted the Boracay’s Chinese captain in absentia sentencing to one year in prison for failing to heed orders to halt the ship for inspection. The Grinch’s owner was ultimately fined several million euros before the vessel was released. The action in Europe coastal waters follows a series of U.S. seizures in the Caribbean and the Atlantic in late 2025 and early 2026.Ukraine, meanwhile, was widening the fight, targeting Russia’s oil supply chain and even striking shadow fleet tankers as far afield as the Mediterranean.

The pinch was beginning to show. Oil and gas revenues in January 2026 were running at roughly half their level a year earlier. Moscow could still meet its wartime budget. One in particular, Promsvyazbank, a state-linked bank with deep exposure to the energy and defense sectors, was taking on a growing share of the risk as more transactions shifted beyond Western financial channels. Its subsidiary A7 operates a cross-border payment platform built to move money outside SWIFT, the Western bank messaging system that underpins sanctions enforcement and anchors the dollar-based financial order. The platform and its ruble-pegged cryptocurrency, A7A5, had been sanctioned by the UK, the United States, and the European Union in 2025. For the first time, the sanctions were hitting the core of Russia’s gray-zone strategy: oil revenues, maritime logistics, and the parallel financial channels that sustained them.

Then Washington’s war with Iran scrambled the logic. Keeping Russian oil off the market made sense when Middle Eastern supply was flowing. It made less sense when one fifth of global seaborne oil had stopped moving. The Treasury waivers followed.

It was a swift and unexpected pivot—one that has effectively killed the G7 agreement to impose a price cap on Russian oil and heightened tensions between Washington and its ostensible allies in Brussels and London. But the divide has been hardening within the alliance of wealthy states since the start of U.S. President Donald Trump’s second term in January 2025. While Washington has held the line on an initial oil price cap the European Union and United Kingdom have progressively moved toward a tighter threshold. Brussels and London first lowered the cap to $47.60 in September 2025 then dropped it to $44.10 on February 1, 2026, via a dynamic mechanism set at 15 percent below the rolling 22-week Urals average.

Washington also pulled back from enforcing sanctions on vessels tied to Russia’s oil trade, effectively freezing designations on Kremlin-linked logistics networks even as the Treasury Department’s Office of Foreign Asset Control (OFAC), increased pressure on ships linked to Iran’s sanction evasion networks. In February 2025, Pam Bondi, who was then Trump’s attorney general, dissolved the Biden-era interagency task force charged with coordinating enforcement of sanctions on Russian oligarchs and entities profiting from the oil business, including the shadow fleet.

Then, in March 2025, Washington vetoed a Canadian proposal to formalize joint intelligence sharing and G7 enforcement on targeted ships, even as Europe and the UK leaned in. The European Union designated 509 vessels in 2025 across four successive sanctions packages; the United Kingdom designated 434. The United States designated 191 vessels in a single last ditch sprint undertaken by the Biden administration before January 25, 2025, then stopped once Trump was in office — zero new designations in the months that followed.

The fracturing within the G7 coalition on sanctions is a feature not a bug of the system–one that has generated a windfall for the legion of brokers and operators behind sanctioned oil trades that profit not just Russia but Iran and Venezuela. The growing divergence between the U.S. and its Western allies matters because the system itself was built for arbitrage at the outset.

Nowhere is that more visible than in Oman, Iran’s neighbor and one of the Gulf’s most practiced mediators between Tehran and Washington. In early January 2025, just as Treasury Department officials in the Biden administration made a last ditch effort to constrain Russia’s energy revenues and clamp down on the shadow fleet’s opaque web of operators, Sovcomflot, Russia’s state shipping giant, began transferring its 80-vessel armada to new owners. In a bid to insure against potential rollbacks under the incoming Trump administration, OFAC officials worked feverishly to identify Sovcomflot tankers with a known history of shady dealings with Russian energy companies, eventually sanctioning 191 ships as they put the screws to major Russian oil producers such as Surgutneftgas and maritime operators like Gazpromneft Marine Bunker LLC.

Within days of Treasury’s January 10, 2025 announcement about the U.S. crackdown on Russia’s seaborne oil trade industry same month, three special purpose companies (SPC’s) incorporated quietly in Muscat under new names, new addresses, and new managers — Citrine Marine, White Agate Marine, and Serpentine Marine — each one a vessel in waiting for oil that was about to become unsellable through any other channel.

The timing was not a coincidence. Sovcomflot’s executives and their legal advisers had watched Washington’s sanctions announcements closely enough to know the company was the next big target. Kharon, a sanctions intelligence firm, identified the Oman-registered corporate structures as part of a wider network with Oman and UAE vessel operators with beneficial ownership ties to 29 ships once owned by Sovcomflot subsidiaries. One of the Oman shell companies, Citrine Marine SPC, took over management of the Cavalier, the Aframax tanker that was one of the first to make port in mid-March in India during the opening days of the waiver period.

The registration reshuffle came two years after Western sanctions pressure prompted Sovcomflot in 2023 to move its overseas base of operations from Cyprus to Dubai. The shipping conglomerate subsequently transferred dozens of vessels to a network of shell company operators that soon drew Western scrutiny and triggered a series of a series of designations lodged variously by the U.S., EU and UK in late 2024 against Sovcomflot related entities and individuals breathed new life into the heart of Russia’s shadow fleet. It is that cluster that has been among the most active since the start of the Strait of Hormuz crisis.

A Frontline Atlas mapping and analysis of 186 shadow fleet vessels tracked during the 30-day U.S. waiver period estimates total deliveries of roughly 57 million barrels across all clusters — a market value of approximately $6.4 billion. Our analysis identified 13 high-confidence delivering vessels traceable to three named Oman shell companies, Citrine Marine, Serpentine Marine, and White Agate Marine, accounted for the largest share of estimated volume: between 22 and 30 million barrels, worth between $2.5 and $3.4 billion. Both figures are estimates derived from changes in each vessel’s waterline depth during the window, calculated against the vessel’s rated cargo capacity and crude oil prices prevailing in March 2026.

The lesson is simple: the experienced operators who prepared in advance are still moving oil. The maneuver has a name in financial circles: regulatory arbitrage. Rather than waiting for a sanctions designation to land and then scrambling to respond, Sovcomflot’s advisers appeared ready to structure the exit in advance, moving assets into a jurisdiction outside the enforcement perimeter as the perimeter closed. It is the corporate equivalent of transferring money to an offshore account before a court order freezes the domestic one. Legal, deniable, and effective.

But not everyone comes out a winner. Analysis of tankers tied more directly to the Iran-Russia pipeline suggests that those forced to improvise as they came under pressure from G7 members on both sides of the Atlantic are struggling–though they are not by any means yet dead in the water. Recent enforcement actions against a small flotilla managed by Promsvyazbank intermediaries illustrate the contrast between ad hoc proxies and professional brokers associated with long-established, well-capitalized institutional conglomerates like Sovcomflot.

In late December 2025, the U.S. Coast Guard began pursuing the tanker Bella 1 off the Venezuelan coast, part of the Trump administration’s declared blockade of sanctioned oil shipments as it prepared for a broader military campaign aimed at toppling Venezuela’s President Nicolás Maduro. What followed was less a single chase than a slow-motion game of evasion. The ship altered course, turned off its AIS location signal, and reappeared under shifting identities as it crossed the Atlantic. At one point, its crew painted a Russian flag across the hull and invoked protection, even as U.S. authorities tracked it under a court-ordered seizure.

Days later, in early January, U.S. forces caught up with the vessel, by then renamed Marinera, and seized it south of Iceland. The episode briefly took on the feel of something larger when a Russian submarine and naval vessels moved to escort it. U.S. authorities brought the tanker into the Moray Firth off the Scottish coast for crew resupply and processing, using British airfields and operational support. The captain’s wife filed an emergency petition in Edinburgh to keep him in Scottish jurisdiction. By the time the court convened, he was already on a U.S. Coast Guard cutter outside UK waters. The ship’s captain, Avtandil Kalandadze, now faces federal criminal charges in Washington.

U.S. officials and analysts suggested the tanker’s movements near Venezuela were part of a broader Russian effort to test American resolve. What became clearer in the days that followed was less dramatic, but more revealing. The Marinera was one of several vessels targeted by U.S. forces for interdiction tied to Burevestmarin LLC, a shell company registered in July 2025 in Ryazan, a provincial city southeast of Moscow. The firm’s Moscow-based director, Ilya Bugai, is native of Crimea and the CEO of Rusneftekhimtorg, a petroleum product trading company owned by Bugai’s business associate Viktor Baransky, another top shadow fleet operative with a documented history of facilitating oil trades for intermediaries tied to Iran’s Islamic Revolutionary Guards Corps, the IRGC.

Baransky’s network has operated at the intersection of Russian, Iranian, and Venezuelan oil trades since at least 2021, when the U.S. Treasury sanctioned structures associated with his informal holding company for transporting Venezuelan crude. Investigative reporting by RFE/RL and its Russian investigative unit Systema has linked Bugai’s firm Rusneftekhimtorg to Baransky’s network through shared corporate intermediaries connected to the financial circle of Ilan Shor — a fugitive Moldovan oligarch sanctioned by the U.S., UK, and EU for election interference on Russia’s behalf and co-founder of A7 with Promsvyazbank. The U.S., UK, and EU have all sanctioned A7. It is not only still running, it is expanding with newly launched partnerships in Africa.

The Marinera is one of six shadow fleet tankers sanctioned by the U.S. with documented ownership histories that cross between intermediaries linked to the IRGC’s Quds Force and Baransky-Shor network’s Buravestmarin outfit. Nine months before the dramatic U.S. raid on the ship triggered the ship’s renaming and re-registration in Russia, the Bella 1 sat anchored in Bandar Abbas, Iran before it steamed its way toward the UAE then onward towards the Caribbean in the summer of 2025.

In December 2025 as U.S. forces bore down on Venezuela, Burevestmarin acquired three tankers in quick succession — the Marinera, Veronica, and Sokolo — all of them purchased from networks with documented ties to Iran’s Islamic Revolutionary Guard Corps. All three were subsequently targeted during Operation Southern Spear, the U.S. naval blockade of Venezuelan oil that preceded Washington’s military intervention in Venezuela.

Two are now in U.S. custody. The third, the Sokolo, has been sitting dark off the coast of Aruba since New Year’s Day, its transponder silent, carrying an estimated two million barrels that no government has publicly accounted for to date. But while part of the Buravestmarin-Baransky fleet has sat idle in Caribbean waters, at least five were able to deliver during the waiver period.

A Frontline Atlas deep dive into the Baransky-Shor network and its connections to Promsvyazbank found that Buravestmarin’s hurried purchase of the Bella 1, Sokolo, and Veronica in late December 2025 coincided with a notable series of A7A5 crypto wallet transactions. It is unclear whether the movement of tokens is related to the vessels’ transfer of ownership from sanctioned Iranian intermediaries linked to the IRGC. But the available data examined for this investigation shows that two arms of the same network of sanctions evasions facilitators–A7A5 and Buravestmarin–were simultaneously building out new operational infrastructure during the same window.

Six weeks after the Treasury Department issued the waiver package, Washington seems inclined to let entropy set in — a de facto reversal of sanctions on Russia’s shadow fleet by neglect rather than decree. The G7 oil price cap sits intact on paper, unable to reconcile Washington, Brussels and Kyiv on how — or whether — to constrain Russia’s ability to fund its war. What is emerging instead is a zombie policy: formally in place, intermittently enforced, and subordinate to the pressures of a tightening energy market. The longer that posture holds, the more the shadow fleet’s share of global oil trade grows, and the weaker the dollar-based financial architecture that makes sanctions enforcement possible in the first place.

The Cavalier discharged its cargo at Vadinar on March 16. By April 13 — two days after the waiver expired — it had already turned back toward the Suez Canal. It is still sanctioned. It is still running. Nothing in the enforcement architecture that existed before the waiver has changed. Two weeks after the Treasury waivers were officially set to expire on April 11 nothing that would stop it had been formally put in place to halt the Cavalier’s operations.

On March 25, the UK’s Defense Secretary John Healey announced that British forces now had legal authority to board sanctioned Russian tankers in UK waters. Thirteen days later, the Russian frigate Admiral Grigorovich escorted two sanctioned tankers through the English Channel. The UK’s Royal Fleet Auxiliary Tideforce was present. No boarding took place.

On April 15, Treasury Secretary Scott Bessent confirmed from the White House podium that the general licenses for Russian and Iranian oil would not be renewed. The following day, the Universal, a Russian-flagged, U.S.-sanctioned tanker that loaded at Vistino on April 6, three weeks after the waiver’s cargo cutoff — was steaming west through the Atlantic under no applicable license and no enforcement action, its destination undeclared.

That turned out to be the right move.

Three days after Bessent said that most of Russia’s stranded seaborne crude had moved to market during waiver period, the Trump Administration reversed course. The shift came as oil-importing countries pressed Washington for relief amid mounting uncertainty driven by dueling American and Iranian naval blockades in the Strait of Hormuz. On April 18, the Treasury Department said it would extend the waiver to May 16. The decision coincided with new data from the International Energy Agency showing Russia’s oil revenues had nearly doubled, from $9.7 billion in February to $19 billion in March.

This is what sanctions entropy looks like. Not a single dramatic reversal but a series of signals that contradict each other — boarding authority announced, no boarding conducted; waivers expired, naval escorts deployed; pressure intensified on paper, relieved in practice by paperwork shuffling and murky financial transactions. Russia has never needed to dismantle Western sanctions. It has only needed Western governments to keep disagreeing about whether and how to enforce them. For four years, that has been enough. The Universal’s journey to Cuba suggests it still is.

Europe still holds instruments Russia cannot ignore: 300 billion euros in frozen sovereign reserves, leverage over the refining loophole it has begun to close, and a proposed maritime services ban. While pro-Russian politicians in Hungary and Slovakia have blocked EU moves to tighten the net around the shadow fleet a window of opportunity may soon reopen. On April 12, Hungarian voters ended 16 years of Viktor Orbán’s rule.Whether the new government in Budapest moves quickly enough is an open question. Orbán spent years as Moscow’s most reliable ally inside the EU. His successor, Peter Magyar, has promised to change that. Whether promises become policy in time to matter is another question entirely.

But there is no debating the structural realities. The Russian sanctions regime now has three speeds: Brussels enforcing, London signaling, Washington reversing. The West has unintentionally built a containment strategy with three gears and no clutch. Russia has been flooring it the whole time.

If you are reading this, you probably know something about the Wagner Group — or you have come across work Ben Dalton and I did at New America to track the Kremlin’s mercenary army and Russia’s irregular warfare strategy.

We’ve likely crossed paths over the years — through reporting, research, or work in the field. Maybe it was in Afghanistan, Pakistan, or Ukraine. Maybe it was over coffee in Washington, Brussels, Berlin, Helsinki, or London where we compared notes on how states and private actors are exploiting legal loopholes, leveraging hidden connections, and using technology to rewrite the rules of the game.

For years, we have followed a single thread: how power moves through the systems built to obscure it.

That thread ran through New America’s Future Frontlines program. Ben and I spent years there working with colleagues at Arizona State University and other organizations to map Russia’s Wagner Group — its networks, its finances, its operations across three continents — until the record was too detailed to ignore. It reached international courts, multilateral institutions, and governments worldwide. My book, Putin’s Sledgehammer (PublicAffairs, 2025), tells that story.

Frontline Atlas is the next chapter of that work — an independent platform built to follow evidence and data wherever it leads.

Most geopolitical analysis works the surface. Frontline Atlas traces what moves beneath it — the sanctions exposure before it becomes designation, the technology chokepoints before they become supply chain crises, the conflict architecture before it escalates.

We’re not done asking questions. There’s more to map and it is moving faster. Datasets change mindsets. Evidence should drive decisions.

We are launching with an investigative series on Russia’s shadow fleet — tracing how oil continues to move through a tightening sanctions environment, and what that tells us about the next enforcement cycle.
