How did escalating geopolitical tensions—including attacks on two ADNOC vessels in the Strait of Hormuz, stalled U.S.–Iran ceasefire negotiations and possible new sanctions, renewed Israeli strikes on Lebanon, the ceasefire’s impending expiration, threats of an indefinite U.S. na

The market priced a large, immediate supply-risk premium: threats to shipping through Hormuz, further U.S.–Iran escalation, attacks on regional and Russian export infrastructure, and the prospect of tighter sanctions all increased the perceived chance that physical barrels and LNG cargoes would be unavailable. That risk lifted Brent roughly 6% for the week to $88.52 and WTI 5.4% to $82.40, despite no certainty that the worst disruptions would occur.

• Hormuz was the central transmission channel. With flows through the strait severely constrained, traders focused on a chokepoint that had handled about 20 million barrels per day of crude and products before the war, with limited alternative pipeline capacity. The IEA said Gulf producers had already cut output substantially as storage filled and bypass options proved inadequate.

• Escalation raised the odds of a longer outage. Attacks on vessels, stalled ceasefire diplomacy, the threatened indefinite blockade, potential new economic-isolation measures against Iran, and renewed regional fighting suggested that the disruption could persist rather than be resolved quickly. This encouraged refiners, traders, and investors to bid up prompt crude for security of supply.

• The Novorossiysk disruption broadened the concern beyond the Gulf. A hit to Russian export capacity reinforced the possibility that simultaneous regional outages could tighten the seaborne crude market, particularly for European buyers that rely more directly on Brent-linked supplies.
