Oil Drops Below $100 as Hormuz Flows Recover
Increased Saudi shipments through the strait and the prospect of US-Iran talks pushed crude to its longest run of declines since June.
Oil fell below $100, heading for its longest run of declines since June, as robust flows through the Strait of Hormuz and diplomacy around the war weighed on prices1. Brent fell 3.4% to settle near $100 a barrel as Saudi Arabia increased crude shipments through the strait2. Crude retreated as the improved flows eased supply concerns, helped by hopes that diplomacy will end the conflict3. Prices fell more than 3% on Monday as tanker traffic and energy flows recovered4.
Aramco has increased exports through the Strait of Hormuz after attacks on its East-West Pipeline forced it to halt some shipments through Yanbu10. Oil exports through the strait are gradually recovering, with ship-to-ship transfers, rarely used before the war, now keeping cargoes moving5. Pakistan has secured safe passage through Hormuz for a second Qatari LNG cargo this month, easing pressure on its strained energy position13.

The risk has not gone away
The waterway remains dangerous. The British military said an unknown projectile struck a tanker as it entered the Strait of Hormuz on Monday, injuring two crew members6. The United Kingdom Maritime Trade Operations centre reported that an LPG tanker was struck by debris from unknown projectiles while transiting outbound from the strait7. Vessels there have come under repeated fire since the conflict began4.
US Vice President JD Vance said substantial volumes of oil and gas continue to pass through the strait despite the disruption he described9. The cost of that continuity is rising. A shortage of oil tankers and record shipping rates through Hormuz could offset falling crude prices and keep pump prices high8. Reuters makes the same point from the other direction: the shuttle system keeping oil flowing does so at a high cost5.
What to watch
Equity markets took the fall in crude as relief. London stocks posted solid gains as oil retreated to $10011. Lower oil prices matter for markets because energy costs influence inflation, corporate margins and consumer spending, and a decline in crude feeds through all three12.
Prices firmed again in early trade ahead of potential US-Iran talks10. Two variables now set the direction, and neither is yet priced with confidence: whether the diplomacy produces an agreement that reopens the strait properly1,3, and whether tanker capacity and freight rates normalise, since those rates can keep refined product expensive even as the crude benchmark falls5,8.
