Oil markets price in prolonged Hormuz crisis at $90 a barrel

Global oil markets have shifted from treating the Strait of Hormuz crisis as a temporary shock to pricing it as a structural feature of the energy landscape, with crude stabilizing around $90 a barrel — roughly 50% above levels at the start of the year. The transition reflects a growing consensus among traders that nearly six months of conflict between the United States and Iran has produced no credible diplomatic path toward restoring normal flows through the world's most important oil chokepoint.

Ceasefire Collapse and Hardening Rhetoric

An interim ceasefire agreed on June 17 has effectively collapsed, with the 60-day negotiating period expired and neither side willing to compromise. Iran warned on Monday it would escalate tensions unless Washington fully implemented the interim peace deal, with a senior Iranian official telling Reuters Thomson Reuters Corporation ↘ 4.69% that Tehran would launch a "timely and precise" attack to break the U.S. naval blockade if diplomacy failed. President Trump has insisted the pact was "over" since July 7 and said Washington was moving closer to defeating Iran.reuters

The rhetoric hardened further this week when Iran said it would adopt a "fully offensive" strategy, while Trump threatened to bomb Oman if it finalized a deal with Iran for joint management of the strait.oilprice

Supply Flows in Freefall

Flows through the Strait of Hormuz, which averaged about 18 million barrels per day before the war, fell to 4.8 million bpd in July and have averaged around 2 million bpd so far in August amid Iranian attacks and the U.S. blockade, according to analytics firm Kpler. Alternative routes through the UAE's Fujairah terminal and Saudi Arabia's Red Sea coast have provided limited relief, but Yemen's Houthis have imposed a blockade on Saudi exports through the Bab el-Mandeb Strait.reuters

Middle East exports averaged just 9.5 million bpd this month — less than half the 21 million bpd in 2025. Adding to the opacity, Gulf producers are increasingly relying on "dark tankers" that disable tracking systems, making it impossible for traders to determine actual supply volumes.moderndiplomacy+1

Refining Strain and Record Diesel Margins

The crisis extends well beyond crude. The diesel crack spread in U.S. refineries surged above $100 per barrel for the first time in history, illustrating a deepening fuel supply crunch. Global refinery throughput in July stood at 81 million bpd, nearly 5 million bpd below year-earlier levels, according to the International Energy Agency, reflecting lost Middle Eastern capacity and Ukrainian drone strikes on Russian refineries. Russia has banned diesel exports until the end of the year in response to domestic shortages.oilprice+1

U.S. gasoline prices reached $4.06 per gallon on Monday, up 29% from a year ago, according to the American Automobile Association — a politically uncomfortable reality for Trump ahead of November's congressional elections. Global observed oil inventories fell by 2.4 million bpd in the second quarter, their largest quarterly draw in at least a decade, while U.S. diesel stocks sit at their lowest seasonal level in three decades.reuters

Benchmark tanker rates from the Middle East to China have surged to $490,000 per day, equivalent to $5 per barrel and nearly ten times higher than at the start of the year, according to LSEG data. The longer the impasse persists, Reuters columnist Ron Bousso wrote, "the less this looks like a temporary supply shock and the more it resembles a structural reshaping of global oil trade."reuters
