The U.S. Department of the Treasury announced it would temporarily ease sanctions on certain Russian oil—what impact will this have on international oil prices?

If the Strait of Hormuz were fully blocked, it would create a 20% global oil supply shortfall. Gulf producers have already cut output by 10 million barrels per day (bpd), while Russia’s oil production currently runs at a maximum of about 7 million bpd—leaving a daily supply gap of roughly 10 million barrels. The G7’s recent decision to release 400 million barrels from strategic reserves is unlikely to deliver more than 4 million bpd to markets due to logistical constraints. Yet we must remember that over 120 million barrels of Russian oil are currently floating at sea aboard ‘shadow tankers’—previously sold at steep discounts. Thus, this sanction relief cannot meaningfully close the supply-side gap. However, the substantial buffer stock already accumulated in the market can suppress sharp price spikes. At current drawdown rates, this cushion would take approximately 80–90 days to exhaust. That implies Iran may need to endure at least another 60-plus days of bombing before oil prices surge dramatically. Accordingly, Polymarket forecasts a 43% probability that the conflict will end by late April and a 73% probability it will conclude within this year—though a ‘slide’ (prolonged stalemate) remains possible.

The U.S. plans to loosen restrictions on the ‘shadow fleet’: In the battle over energy sanctions, has soaring freight costs ultimately forced a retreat?

On October 14, a U.S. official told media outlets that the Trump administration was considering easing sanctions on vessels belonging to the ‘shadow fleet.’ This term refers to a gray-area maritime transport network—comprising numerous aging tankers—deployed by Russia, Iran, Venezuela, and others after the outbreak of the Russia-Ukraine war to circumvent Western sanctions. These ships routinely change names and flags, disable AIS transponders, and conduct ship-to-ship transfers to clandestinely deliver oil to buyers. The White House’s rationale is straightforward: global shipping rates have surged to historic highs, and Washington seeks to cool them down. This is no mere rhetorical gesture. Oil tanker freight rates have spiked unprecedentedly this year: the Baltic Dirty Tanker Index (BDTI) closed at 5,499 points by late September—more than five times its median level last year; VLCC daily charter rates on the Middle East–Far East route briefly exceeded $1 million. Sanctions have removed large volumes of compliant tonnage from service; detours and transshipments have doubled voyage distances; and roughly 20 million barrels of Iranian crude remain stranded at sea, unable to find buyers—neither daring to dock nor freeing up shipping capacity. Just prior to this announcement, Trump had also temporarily lifted sanctions on Russian diesel. These two consecutive moves point toward a single objective: suppressing energy prices to alleviate domestic gasoline-price anxieties ahead of the November 3 midterm elections. Yet the costs are equally evident—Ukrainian President Volodymyr Zelenskyy, multiple European governments, and even some Republican senators swiftly voiced strong criticism. Ukraine fears increased Russian oil revenues could directly fund its war effort; Europe worries the carefully constructed sanctions architecture—built over years—may now be dismantled piece by piece by the White House; France even seized a suspected Russia-linked shadow tanker in the Indian Ocean, signaling its clear divergence from Washington’s ‘pragmatic’ approach.

US Plan to Ease Shadow Fleet Sanctions Unlikely to Free Up Many Tankers, Analysts Say

Analysts predict US plans to ease shadow fleet sanctions will have minimal impact on tanker availability due to insurance and maintenance hurdles. Kpler estimates only a small portion of sanctioned vessels could realistically rejoin global trade.
