Crude slips as Gulf exports recover and Washington adds supply options

With crude ending at the day's weakest level following a US-session slide, near-term momentum appears to support supply relief, even as Brent's double-digit monthly advance indicates the war premium remains embedded in prices. A trading executive said Tehran's bargaining power in discussions with Washington declines as more oil leaves the Middle East, a view that ties the physical recovery directly to diplomacy. Diesel is the main policy focus, with US futures stronger while European contracts slipped, and regulatory changes or emergency stock releases could add downward pressure on the complex. For bulls, the danger is extra policy supply arriving at a time when exports are normalising; for bears, it is the recovery stalling or diplomacy breaking down.

Recovering Middle East flows, a US reserve-release proposal and reporting on Russian sanctions dominated over Iran war risk; crude fell to its session low while Brent still carried a large September gain.

Summary:

• On Tuesday, Brent ended about 2.5% lower near $103 a barrel, and WTI fell roughly 3.5% to around $89, with both benchmarks settling at session lows after selling off during US trading.
• Yanbu tanker loadings have restarted after Saudi Arabia brought the East-West Pipeline back online, and Middle East crude exports in September climbed back to about 16 million barrels a day, the highest level since the US-Israeli war on Iran got under way in late February.
• Up to 40 million barrels from the Strategic Petroleum Reserve were placed on offer by the Department of Energy, yet a comparable June offering produced borrowing pledges of just around 500,000 barrels.
• Mediation between Washington and Tehran is still going on, according to Qatar, while Trump rejected the idea that he had offered Iran anything to end the war.
• Russia sanctions relief linked to the release of a prisoner has Trump's backing, The Atlantic reported, potentially opening the door to US deals in Russian oil, diesel and other commodities.
• Emergency diesel inventories in the EU should be reduced, the White House has argued, and it is considering expanded sales of red-dyed diesel instead of a diesel export ban.

Tuesday brought another decline in oil futures, with both benchmarks finishing at the day's lows. Recovering Middle East exports and a string of US supply headlines counted for more than lingering fears that the US-Israeli war on Iran would disrupt flows. Brent settled about 2.5% lower at roughly $103 a barrel, while West Texas Intermediate lost about 3.5% to around $89. Both benchmarks gave up earlier European-morning gains during the US session, though Brent remains set for a double-digit monthly advance and WTI is heading for a gain of about 4%.

The supply picture improved over the day. Tanker loadings at the Red Sea port of Yanbu were back under way, according to trade sources and shipping data, after Saudi Arabia returned the East-West Pipeline to service. Figures published by Kpler on Monday put September crude exports from Middle East producers at about 16 million barrels per day — the strongest since the conflict started in late February.

Diplomacy played a role in the early softening as well. Ongoing Qatari mediation is designed to build common ground between Washington and Tehran, the government said, suggesting a diplomatic route is still open. The president, however, insisted that no offer had been made to Iran to end the war, pushing back on press reports that quoted US officials as saying he would relax sanctions and hand over frozen funds in exchange for concrete steps on Tehran's nuclear programme.

Further downside came from Washington. According to The Atlantic, the Trump administration supports easing sanctions on Russia as part of a prisoner-release deal, opening the way for US commercial agreements covering Russian oil, diesel, rare earth minerals and other commodities. On a separate front, the Department of Energy placed up to 40 million barrels from the Strategic Petroleum Reserve on offer. An earlier June proposal to lend the remaining 40 million barrels under an International Energy Agency pact drew corporate borrowing commitments of just about 500,000 barrels, according to the administration.

Diesel stayed front and centre. Washington has pressed the European Union to cut emergency diesel stockpiles to bring down worldwide prices, saying several member states have fallen short of their reserve-release promises. Two people familiar with the talks said Trump is also mulling regulatory changes that would enable wider sales of red-dyed diesel and let certain purchasers sidestep the federal fuel tax, with that measure now a top candidate to replace an export ban on diesel. US diesel futures traded about 2.5% higher, while European diesel contracts moved slightly lower.

The focus now shifts to whether Middle East export flows keep recovering, whether the SPR barrels actually get taken up, and whether talks between Washington and Tehran make headway.
