Brent’s move on Wednesday, October 21, reflected two opposing signals: fresh threats to Gulf supply helped lift prices above $110, while signs that oil was moving through the region again limited the rally. A draw in U.S. crude inventories added support, but it was not enough to keep prices climbing throughout the session.

A rally built on supply concerns
Brent had touched $111.99 on Tuesday, a five-month high, before settling at $108.79, down 76 cents. On Wednesday, December Brent futures rose $1.59, or 1.5%, to $110.38 at 03:50 GMT. A later Reuters snapshot put Brent up $1.32 at $110.11 by 07:47 GMT. These are different intraday observations, not a single closing price.

The immediate concern was the risk that attacks could disrupt oil shipments or energy infrastructure. Kpler counted at least 18 vessel attacks over the preceding two weeks, while analysts warned that Iranian targeting extended beyond the Strait of Hormuz into the Gulf of Oman. Traders were also watching Red Sea shipping risks and threats to Saudi energy infrastructure.

Diplomacy offered little reassurance. Iran told Pakistan’s army chief, Field Marshal Asim Munir, who was in Tehran as part of mediation efforts, that it would not hold talks with Washington until its demands were met. The available reporting does not specify those demands.

Why Brent gave back some gains
Geopolitical risk was only one side of the market’s calculation. Brent later traded below $108 as relatively strong flows through the Strait of Hormuz offset concerns about attacks on ships and energy infrastructure. A later Wednesday Reuters report put Brent at $109.04 at 14:50 GMT, showing that prices moved around during the day; the dip below $108 should not be read as the final settlement.

The supply recovery was substantial, but not complete. The International Energy Agency reported that Gulf producers’ crude exports rose by 4.4 million barrels per day in September, reaching 13.9 million barrels per day—more than 75% of pre-war levels. That recovery helps explain why stronger physical flows could temper prices even as security concerns persisted.

U.S. inventories added support
The U.S. Energy Information Administration’s weekly figures showed commercial crude inventories fell by about 3.1 million barrels in the week ended October 16, to 412.5 million barrels. Stocks were about 3% below the five-year average for that time of year. The decline was larger than the 820,000-barrel draw expected in a Reuters poll, while the American Petroleum Institute’s earlier estimate was a 4.93-million-barrel fall.

The product figures were mixed: gasoline inventories fell by about 3.0 million barrels, while distillate inventories rose by 1.7 million. So the report showed draws in crude and gasoline, but not across every fuel category.

The day’s price action was therefore a tug-of-war: shipping and diplomatic risks raised the possibility of tighter supply, while recovering Gulf exports and Hormuz traffic suggested more barrels were reaching the market. Falling U.S. crude stocks reinforced the early rise, but did not eliminate the countervailing effect of improved flows.
