Oil ends mixed, Brent near $106 after booms near Aramco's Dhahran HQ

The bigger message is coming from the deferred curve. WTI futures for calendar 2027 set a record for a 12th consecutive session, trading near $84, while Brent's 2027 strip reached fresh highs around $90 on Monday. That points to the market expecting a sustained shortfall in supply rather than solely a war premium on the front month. Diesel is still the main pressure point, with refined products stronger than crude and refining margins staying elevated. Since the Dhahran reports arrived late in the day, the Asian open will be the first meaningful test of how much Aramco infrastructure risk gets built back into Brent. A tighter Brent-WTI spread meanwhile suggests Middle East risk is partly balanced by the possibility of additional Russian barrels.

This is a quick crude-market catch-up, in case it is useful to anyone.

Earlier:

• Crude futures settled $0.40 higher, at $94.14

Crude is sitting between a Russian diesel deal set to add supply and a Saudi-Houthi war that has now arrived at Aramco's headquarters.

Summary:

• Brent closed down by almost $1, roughly 1%, at about $106, following Monday's strongest settlement since mid-September; WTI ended roughly 40 cents higher near $94, its best close since late September.
• Expectations that the US-Russia diesel export pact might release Russian barrels balanced Middle East risk; the Kremlin said the agreement has no direct connection to Ukraine peace negotiations.
• Accounts of loud booms emerged near Saudi Aramco's Dhahran headquarters as the Saudi-Houthi war escalates; Aramco offered no comment.
• OPEC reported a sharp increase in OPEC+ production for September, with Saudi Arabia raising crude output to roughly 8.4 million barrels per day from about 6.2 million in August.
• The producer group lowered its 2026 demand growth projection for a sixth consecutive month while lifting its view for next year, pointing to the need to restock inventories drained by the Iran war.
• Trump said the Houthis were attempting to push oil prices higher ahead of the US midterm elections.

Crude finished mixed on Tuesday as hopes that a US-Russia deal on diesel exports might free up additional Moscow supply offset a worsening conflict between Saudi Arabia and Yemen's Houthis that puts Gulf energy infrastructure at risk.

Brent futures ended the session near $106 a barrel, off by almost $1, or roughly 1%, after Monday's close marked the strongest since mid-September. US West Texas Intermediate gained about 40 cents, settling around $94 and posting its best finish since late September, according to Reuters.

Moscow said it could not see any direct tie between the diesel agreement and its stance on Ukraine peace negotiations. That response followed a Reuters report saying US President Donald Trump's envoys had informed Ukrainian officials that the arrangement was meant to help draw Russia back to the negotiating table. Trump said the Russian diesel would go to markets abroad rather than the US. US diesel futures were nevertheless up around 5%, suggesting traders doubt the deal will relieve strained product supplies. Diesel has recently reached record prices in numerous regions following Ukrainian strikes on Russian energy facilities and Iranian assaults on Middle East infrastructure.

In the Gulf, six sources told Reuters that loud booms sounded late Tuesday near Aramco's headquarters in Dhahran, the hub of Saudi Arabia's oil sector. One source claimed the building had been hit, although it was not clear whether that was a direct strike or debris; four sources reported that an evacuation order came down. Aramco offered no comment. The Saudi-led coalition said debris from an intercepted missile landed on a residential district.

Earlier, Houthi-run media said the coalition had struck a Yemen Petroleum Company fuel depot on Sanaa's outskirts, and the Houthis then warned they would target Saudi oil installations. For a week the group has been launching missiles and drones at Saudi sites, among them Riyadh's international airport. Trump accused the Houthis of intentionally attempting to raise oil prices before the US midterm elections and said a decision on Iran was coming very soon. In a separate development, reports said Israeli Prime Minister Benjamin Netanyahu had talked with Trump last week about a possible joint operation against Iranian military and nuclear targets; that conversation took place before Trump said he would avoid striking Iran ahead of the US midterm elections. Iranian officials said a tanker they called in breach of regulations caught fire in the eastern Strait of Hormuz.

Turning to supply, OPEC said OPEC+ output climbed sharply in September, led by Saudi Arabia increasing crude production to roughly 8.4 million barrels a day from approximately 6.2 million in August, even with ongoing Hormuz shipping disruption. Around a fifth of world oil supply passed through the strait before the US and Israel attacked Iran in February. OPEC also lowered its 2026 demand growth forecast for a sixth straight month and lifted its projection for next year, saying inventories depleted by the Iran war need to be rebuilt.

As another indication of deepening geopolitical tensions, the head of Britain's domestic intelligence service said Russia and Iran were intensifying hybrid warfare operations in the UK. Because the Dhahran reports emerged near the end of the session, traders will watch the Asian open for the first market assessment of the danger to Saudi infrastructure.
