Hormuz closure creates largest oil shock since WWII

The persistent deadlock in the Strait of Hormuz represents the largest oil supply disruption since World War II, according to J.P. Morgan strategists. US President Trump rejected Iran's latest peace proposals on May 11, stating the ceasefire was on 'massive life support,' effectively ending near-term hopes for a rapid reopening of the channel. Crude oil has climbed, with WTI rising near $86, while Brent and other petroleum indices reflect sustained risk premium. An oil supertanker hauling Iraqi crude that exited the Gulf on Sunday has halted in the Gulf of Oman, signaling shipment delays and supply chain stress.

Goldman Sachs and Bank of America have both delayed their Fed rate-cut calls, citing 'persistent' inflation risks and strong jobs data. The latest CPI print is due May 13 and will be critical for recalibrating expectations.

Energy producers are benefiting, but importers face margin compression. Petrobras missed profit estimates despite the war-driven oil rally because it kept domestic gasoline prices stable, absorbing margin pressure. Copper and other industrial commodities are steadying near records as traders balance supply disruption upside against weakening growth signals. Airlines like United and low-cost carriers face existential margin pressure; Deutsche Bank analysts note the industry is 'ripe for mergers' as fuel costs surge. Fertilizer makers like Mosaic are paradoxically struggling despite higher input prices, facing demand destruction in key markets.

Defense stocks may extend gains as elevated geopolitical risk sustains a premium.

A rapid reopening of Hormuz would be massively deflationary; prolonged closure could force central banks to delay rate cuts and extend the 'higher for longer' regime.
