NextFin News - The Trump administration is weighing a plan to ease US sanctions on so-called shadow fleet tankers that have carried oil and petroleum products from Russia, Iran and Venezuela, a US official said, in an attempt to relieve record freight rates that have pushed crude prices above $100 a barrel. The proposal would let previously sanctioned vessels carry "legal oil" again, with shippers applying to the Treasury Department for permission. But ship-tracking firm Kpler estimates only about 24 vessels could realistically rejoin global trade, and analysts warn the move would do little to fix the shipping bottleneck that is driving the tanker crisis.
The Proposal and the Immediate Market Reaction
Oil prices fell more than $1 in early trade on Thursday as investors weighed the potential policy shift against continuing attacks on commercial shipping through the Strait of Hormuz. Brent crude futures fell $1.39, or 1.31%, to $104.67 a barrel by 0116 GMT, while US West Texas Intermediate crude futures were down $1.02, or 1.07%, to $94.07, reversing gains from the previous session.
The prior session had sent WTI to a three-week high after Houthi forces attacked Saudi Aramco's headquarters and Iran said it was deploying new tactics to target ships in the Strait of Hormuz. Two vessels - a container ship and a dry bulk carrier - sank near the strait in the preceding 24 hours after being hit by projectiles in separate incidents, maritime officials said on Wednesday. Attacks around the waterway have surged over the past 10 days, with Iran saying it is stepping up strikes in response to US port blockades and tougher sanctions introduced last month.
The tanker market, not the oil market, has become the binding constraint. Freight rates on the Persian Gulf-to-China route topped $1.4 million per day for very large crude carriers in the first week of October, after already exceeding $1 million per day in September, according to trade data compiled from broker and ship-tracking sources. The surge reflects a physical bottleneck: increased oil flows out of the Strait of Hormuz are being handled through ship-to-ship transfers in the Gulf of Oman, tying supertankers up for weeks and pulling vessels away from other key trade routes such as the US Gulf Coast to Asia.
Why Easing Sanctions Would Free Fewer Tankers Than It Appears
The administration's logic is straightforward: if sanctioned ships can return to legitimate trade, the effective tanker fleet grows, freight rates fall, and crude prices cool. The arithmetic is less forgiving.
Kpler tracks about 160 supertankers under US sanctions, roughly 22% of the commercial fleet. Of those, 46 - 27% - are more than 20 years old, an age at which major buyers and insurers typically refuse to engage. Once age is taken into account and tankers owned by Iran's National Tanker Company are excluded, Kpler said, only about 24 ships could rejoin global trade.
That is a rounding error against a market consuming vessel capacity by the day. Even those 24 ships would face a second barrier: they lack the certification, insurance and maintenance needed to enter mainstream trade. "Companies are unlikely to charter tankers that were recently under sanctions as significant risks remain in dealing with vessels," said David Tannenbaum, director of sanctions consultancy Blackstone Compliance Services and a former US Treasury sanctions specialist. "For tankers engaged in Russian trade, EU sanctions still exist while for those engaged in Iranian trade, there is still a lot of liability as the ships were sanctioned for supporting a terrorist organization."
Kpler put the point more bluntly: "Kpler expects the measure to have virtually no impact on the current tanker crisis. The proposal assumes that removing sanctions will translate into additional commercially available capacity. In practice, the relationship is far more complicated." Aging vessels, uncertain seaworthiness and unresolved insurance, crewing and management arrangements will limit the ships' commercial appeal, the firm said.
The shadow fleet exists because of the sanctions architecture it is now being asked to re-enter. It grew rapidly after the Group of Seven imposed a price cap on Russian seaborne crude in December 2022, which forced Moscow to build a parallel shipping system outside Western insurance and financing. The Treasury Department sanctioned 183 Russian-linked vessels in the final days of the previous administration, and Britain added 12 more shadow-fleet tankers to its sanctions list on October 8. These vessels typically sail under flags of convenience with opaque ownership, switch off transponders to disappear from tracking, and rely on non-Western insurers - exactly the attributes that make them unusable for mainstream charterers even if Washington removes its name from the list.
There is a further complication the proposal does not resolve. US sanctions are only one layer of the sanctions architecture. The European Union continues to enforce its own restrictions on Russian oil shipments, and private insurers - above all the UK-based mutual clubs that underwrite most global shipping liability - remain reluctant to touch vessels with sanctioned histories. A vessel cleared by Washington would not automatically be cleared by Brussels, London or the insurers that underwrite global shipping. The bottleneck is not the number of hulls; it is the number of hulls that can be insured, certified and chartered without legal risk.
The Second-Order Question: What the Market Is Really Pricing
The shadow-fleet discussion is the latest in a string of ideas the administration is considering to lower fuel prices and inflation. It follows a separate, more concrete move announced by Treasury Secretary Scott Bessent, who said the United States was preparing to lift sanctions on approximately 140 million barrels of Iranian crude already sitting on tankers at sea.
"In the coming days, we may unsanction the Iranian oil that's on the water. It's about 140 million barrels," Bessent said in a television interview. "In essence, we will be using the Iranian barrels against the Iranians to keep the price down for the next 10 or 14 days as we continue this campaign. So we have lots of levers."
The two measures point in the same direction but address different problems. The 140 million barrels of stranded Iranian crude is a supply-side lever: it would add physical barrels to the market and, according to reporting, divert them away from China toward buyers in Japan, South Korea, Malaysia, Singapore and India. The shadow-fleet proposal is a shipping-capacity lever: it aims to increase the number of vessel-days available to move oil.
That distinction matters because the current price spike is a shipping problem wearing an oil-market mask. Energy Aspects noted that record freight rates are dampening demand for US crude, and the consultancy said easing sanctions on tankers used for Russian or Venezuelan crude would not make much difference to tanker availability because most such tankers have been actively trading over the past three months. In other words, the sanctioned fleet is already working; the shortage is in the clean, insured, certifiable fleet that can move freely.
The second-order consequence runs through US export competitiveness. When freight on the Gulf-to-Asia run consumes a large share of the landed cost, Asian refiners substitute toward Middle East grades that travel a shorter distance, and US crude sits in storage or sells at a deeper discount. High tanker rates therefore act as an implicit tax on US producers - the very constituency the administration's fuel-price agenda is meant to serve. That is why Washington is reaching for unconventional levers even as it maintains maximum pressure on Iran's financial system elsewhere.
There is a credibility cost to that balancing act. Washington has spent years building sanctions on Iranian oil specifically to cut off Tehran's primary source of income, and as recently as February 2026 it was still adding new sanctions targeting Iran's shadow oil fleet. Reversing course to release barrels onto the market signals that price relief can trump enforcement - a trade-off that adversaries will price into future sanction design. A Democratic senator, Andy Kim of New Jersey, the ranking member on the Senate Subcommittee on National Security and International Trade and Finance, criticized the direction of travel.
Who Benefits and Who Is Exposed
If freight rates do ease - whether through policy, de-escalation in the Strait, or both - the beneficiaries and the exposed are asymmetrical. Tanker owners are the clear winners of the current dislocation. Frontline reported second-quarter average earnings of $152,700 per day on its VLCC fleet, $111,400 per day on Suezmax and $92,400 per day on its LR2/Aframax fleet, with 86% of its VLCC days already booked at $156,900 per day. Teekay Tankers reported spot bookings at $141,800 per day for VLCCs, $121,800 for Suezmaxes and $98,000 for Aframax/LR2 fleets.
Those rates are multiples of long-run norms, and they are the reason the administration is reaching for unconventional levers. Refiners and oil importers are on the other side of the trade, paying the freight premium embedded in landed crude costs. US crude exporters are exposed as well: high tanker rates make US barrels less competitive in Asia, which is why energy consultants flagged weakening US crude demand. The International Energy Agency said on Wednesday that Russia's crude oil production rose by 65,000 barrels per day in September to 8.43 million bpd, though it remained down 870,000 bpd year over year. The agency also said crude oil exports from Middle East Gulf producers rose by 4.4 million bpd in September to around 75% of prewar levels. The supply is there. The ships to move it efficiently are not.
The Cyclical Read, the Counter-Thesis, and the Signal That Would Break It
The tanker crunch is cyclical, not structural. It is being driven by a war-driven disruption to a chokepoint, by ship-to-ship transfers that immobilize vessels for weeks, and by war-risk insurance premiums that make some voyages uneconomic. All three are mean-reverting: if the Strait of Hormuz reopens to normal transit, vessel-days are released back into the system quickly, and freight rates collapse toward long-run averages. The shadow-fleet easing is a policy band-aid on a cyclical wound; it neither causes nor cures the underlying shortage.
The strongest counter-thesis is that the dislocation could persist longer than a typical cyclical spike because the sanctions architecture itself has permanently fragmented the tanker market. With the United States, the European Union and Britain each maintaining separate vessel lists, and with a shadow fleet of aging tankers now operating outside Western insurance and certification systems, the market has effectively split into two pools. In that reading, even a full de-escalation in the Gulf would leave a smaller effective fleet of Western-compliant vessels than existed before the war, keeping a floor under freight rates. The seizure of sanctioned tankers by India and detentions by France show that enforcement is intensifying, not receding - which pushes more tonnage into the opaque pool rather than back into the compliant one.
That argument has force, but it mistakes the margin for the whole. The fragmentation is real, yet the current rate spike is being set at the margin by the Hormuz bottleneck, not by the structural shrinkage of the compliant fleet. The falsifying signal is specific: if VLCC rates on the Gulf-to-East Asia route remain above $500,000 per day for four consecutive weeks after Strait transits return to normal and ship-to-ship transfers wind down, the structural-fragmentation thesis overtakes the cyclical one. Below that threshold, the spike is a war premium, and it will mean-revert.
What to watch next: the weekly US Energy Information Administration inventory data; any official Treasury announcement on the shadow-fleet mechanism; and, above all, shipping traffic through the Strait of Hormuz. The administration is trying to fix a shipping problem with a sanctions tool. The market will judge the effort by the freight rate, not the headline.
Scenarios: What Unfolds Across Time Horizons
Three paths are now in play, and they point in different directions depending on the horizon. In the base case, the Hormuz disruption eases within weeks, ship-to-ship transfers normalize, and freight rates fall sharply from their record highs; the shadow-fleet plan, if implemented, adds at most a few dozen marginal vessels and is barely noticed in the rate data. In the upside case for rates, attacks intensify or the strait is further restricted, freight climbs toward the $2 million-per-day range seen in past acute crises, and tanker equities re-rate higher still - at which point the administration's price-relief tools would look increasingly inadequate. In the downside case, a rapid de-escalation combined with the release of the 140 million barrels of Iranian crude produces a swift move lower in both freight and crude, and the shadow-fleet debate becomes a footnote.
Short-term, rates stay elevated while the Hormuz disruption persists and any policy change is negotiated. Medium-term, the 24-ship ceiling on releasable tonnage means the shadow-fleet plan alone cannot restore normalcy. Long-term, the structural residue is a more fragmented tanker market and a sanctions regime that has traded enforcement purity for price relief - a shift that outlives this particular crisis.
The real lesson is uncomfortable for policymakers: you cannot unsanction your way out of a shipping shortage when the ships that matter are already working, already insured, and already priced into a market that has moved on.
