The Oil War Flipped the Fed: Hormuz Strikes Push Markets to Price a December Hike, Not a Cut

Israel–Iran strikes on the war’s 100th day held Brent at $94 and drove December Fed-hike odds to 72%, from 45% a week ago. For globally-expanding firms, the cheap-funding era is over — and gold, the classic war hedge, is failing.

The decisive force in markets is no longer the Fed — it is a barrel of crude. Israel and Iran traded missile strikes on the 100th day of war, holding Brent at $94.25 and the Strait of Hormuz near-shut. Hot U.S. payrolls did the rest: markets now price a 72% chance the Fed hikes in December, up from 45% a week ago. The 2026 rate-cut trade is dead.

What happened. Brent settled Monday up 1.25% at $94.25 and WTI at $91.30, after spiking above $98 intraday as a fragile 60-day ceasefire frayed and Israel struck targets in western Iran. With ~45% of China’s crude imports and ~38% of all Hormuz flows transiting the strait, the supply premium is structural, not a one-day spike. May payrolls of 172,000 — double the ~85,000 consensus, unemployment steady at 4.3% — lifted the 10-year Treasury yield to a two-week high near 4.57%.

Why it matters. This is a stagflationary supply shock, not a demand boom. Oil-fed inflation has forced markets to price out every 2026 cut and contemplate hikes, raising the global discount rate and widening credit spreads for leveraged and emerging-market issuers. The tell is gold: down to a two-month low of $4,314 even amid open war — a real-rate shock overpowering the safe-haven bid. The textbook hedge has broken.

China & global angle. For Chinese firms going global, the paradox cuts both ways. Energy security is the acute risk: Beijing’s strategic reserves can buffer a multi-month disruption, but Belt-and-Road logistics and Gulf supply lines are exposed. Yet the offshore yuan, near 6.79 and up 2.3% year-to-date, is one of the only currencies to gain against the dollar since the war began — handing Chinese acquirers relative purchasing power abroad as dollar funding costs climb.
