Key Highlights

● WTI crude fell 0.92% to $101.83 a barrel in Thursday's session.

● US crude stocks fell 1.9 million barrels, the fourth weekly draw in a row.

● Strategic reserve holdings of 282.6 million barrels are the lowest since 1982.

● Europe plans to release 42 million barrels of oil reserves over three months.

WTI crude oil fell 0.92% to US$101.83 a barrel in Thursday's session on 29 October as talk of diplomacy with Iran returned. The move matters to refiners such as Valero (NYSE:VLO), which buy crude by the million barrels a day and earn their profit from the gap between crude and the fuels they sell.

The December NYMEX contract (CLZ26) is down US$0.95 on the day. Even after the dip, WTI is up 2.40% on the week and 12.65% on the month, 77.40% since the start of the year and 68.17% from a year ago. Brent, the international benchmark, fell 0.48% to US$114.77.

Diplomacy Against Tight Stocks

Crude is being pulled two ways. Contacts between Washington and Tehran are easing the fear of renewed military action, while US inventories are shrinking and attacks on Gulf energy facilities keep supply risk alive. The result is a market that has stayed above US$100 even on a down day.

Washington, Tehran and the Midterm Calendar

The geopolitical backdrop changed shape on Thursday. US Vice President JD Vance reportedly contacted Iranian officials, and Foreign Minister Abbas Araghchi said Tehran remained open to diplomacy. President Donald Trump confirmed communication with Iranian authorities, though he described the outreach as focused on medical supplies and acknowledged that it was uncertain whether negotiations would succeed. Qatari mediators have also presented a new draft deal.

The risk has not gone away. Earlier reports said US officials had told Gulf states to prepare for a short, intense campaign after the 3 November midterm elections, and a third US carrier group was reported heading toward the Gulf. Markets are now trading the election date as a turning point.

Supply Under Pressure

Physical supply has its own worries. Reports describe repeated Houthi attacks on Saudi energy facilities and a fire near Ras Tanura, Saudi Arabia's biggest oil-export terminal. The fire was contained, though the extent of any damage was unclear.

Against that, Europe plans to release 42 million barrels of oil from reserves over the next three months, with a substantial share in diesel, in an effort to add supply and moderate energy costs. Regional energy flows have also recovered to levels close to those before the war.

US Inventories Keep Shrinking

The EIA reported a 1.9 million barrel draw in crude stocks, the fourth weekly fall in a row. For the week ended 23 October, commercial crude stocks stood at 410.6 million barrels, about 4% below the five-year average. Stocks at Cushing, Oklahoma, the delivery point for WTI, fell by 624,000 barrels, and holdings in the Strategic Petroleum Reserve fell to 282.6 million barrels, the lowest since October 1982.

Fuels tell a mixed story. Gasoline stocks rose 3.87 million barrels, though Midwest gasoline inventories are at record lows. Distillate stocks fell 1.5 million barrels, leaving them 10% below their five-year average, which helps explain why heating oil, at US$4.72 a gallon, is still more than 95% above a year ago even after Thursday's 1.90% fall.

What It Means for Refiners and Producers

For refiners the price of crude is a cost as well as a benchmark. Valero reported third-quarter net profit of US$6.828 billion and refining operating profit of US$8.782 billion on 22 October, with throughput near 3 million barrels a day. Those results show how profitable the business is when fuel prices stay ahead of crude. Today's moves show the other side: crude fell 0.92% while heating oil fell 1.90% and gasoline slipped 0.05%, so margins depend on which fuel is moving.

Producers see the opposite effect. ExxonMobil (NYSE:XOM) reports third-quarter results and holds its earnings call on 30 October, which will show how a month of crude near US$100 and above is feeding through to upstream earnings.

Crude Watch: OPEC+, the Midterms and Exxon's Results

The next catalysts arrive in quick order: Exxon's call on 30 October, the OPEC+ meeting on 1 November and the US midterm elections on 3 November. Weekly EIA inventory data, including Cushing stocks, and any news on damage at Ras Tanura will also guide prices.

Prices could firm if US strikes resume, if the reported Ras Tanura damage is confirmed or if inventories keep falling. They could ease if a credible deal emerges between Washington and Tehran, if Saudi infrastructure proves intact or if the European reserve release adds enough supply.
