Brent holds above $100: Hormuz disruption, IEA stock releases and a diesel squeeze that could last into 2027
Crude oil is heading for another weekly gain. Brent is trading around $105 a barrel and WTI around $97 as of Friday, October 16. WTI is on track for a weekly rise of more than 5%, while Brent is roughly flat on the week. The mix of drivers this week shows a market pulled between real supply disruption and official efforts to calm it, and the most acute pressure is now in diesel rather than crude.
What's moving the market
1. The Strait of Hormuz. Shipping through the world's most important oil chokepoint is still disrupted by attacks linked to the Iran conflict, and the picture depends on whose data you read. Tanker-tracking data from Kpler suggests Gulf crude flows through Hormuz fell to around two-thirds of normal as Iranian military activity intensified, a loss of several million barrels per day. The International Energy Agency, by contrast, says Middle East exports have broadly recovered to pre-crisis levels. Gulf producers have cut prices to keep crude moving to Asia, and ship-to-ship transfers off India have surged as traders reroute cargoes. When credible sources disagree this much, markets tend to keep a risk premium in place until the picture clears.
2. Emergency stocks. The IEA says its coordinated emergency release will overshoot its original target. Member countries have agreed to speed up the remaining releases, with G7 members pledging around 100 million barrels of diesel and other reserves. Washington has also eased sanctions so that Russian diesel can reach global markets. These releases cap spikes, but they draw down buffers that will eventually need to be rebuilt.
3. US inventories. A large draw in US crude stocks, reportedly around 8–9 million barrels, explains why WTI outperformed Brent this week.
Diesel: the real squeeze
The most important line in the IEA's latest report concerns diesel. It expects the global diesel shortage linked to the Iran war to last into next year, with inventories not recovering until the second half of 2027. Gulf refineries and product exports have been badly affected, and diesel is much harder to replace than crude.
For traders, this matters because:
Is $100+ justified?
Not everyone thinks so. Some analysts argue that current prices look "lofty". In their view the world is not actually running out of oil: the war has mainly wiped out the comfortable surplus built up in 2025, rather than creating a deep structural deficit. ING notes that if Hormuz flows stay sustained, the risk premium could erode quickly. The bull case rests on further escalation, continued attacks on Gulf infrastructure and the gradual exhaustion of emergency stocks.
Levels and catalysts
Bottom line: Crude is pricing a persistent but not catastrophic disruption. The tightest part of the market is diesel, where shortages could last well into 2027. For futures traders, that means watching product markets and crack spreads, not just the headline crude price.

Gulf refineries and product exports have been badly affected, and diesel is much harder to replace than crude.
For traders, this matters because:
- Refining margins (crack spreads) stay wide. When diesel is scarcer than crude, the diesel crack can stay elevated even if crude prices stabilise.
- Inflation stays sticky. Diesel moves goods. High diesel prices feed into transport and food costs and the producer-price data, which was exactly what surprised markets this week.
- Heating-oil futures (ULSD) can diverge from crude as the northern hemisphere winter approaches.

Levels and catalysts
- Brent: $100 is the key psychological level. A sustained break below it would suggest the risk premium is unwinding. Holding above $105 keeps the door open to the recent highs.
- WTI: the mid-$90s area is short-term support. Watch the Brent–WTI spread, which is unusually wide at around $8 and reflects how much of the risk is centred on Middle East seaborne supply.
- Headlines: attacks on tankers or Gulf facilities, any ceasefire or shipping deal, and the pace of IEA releases.
- Weekly EIA data (Wednesdays): crude and especially distillate inventories.
- Central banks: oil is now a direct input into Fed and ECB decisions (October 28–29). A further oil spike raises the odds of more rate hikes, and those hikes would eventually hurt oil demand.
Bottom line: Crude is pricing a persistent but not catastrophic disruption. The tightest part of the market is diesel, where shortages could last well into 2027. For futures traders, that means watching product markets and crack spreads, not just the headline crude price.
