When oil jumped above $90 a barrel just days ago, military tensions between Israel and Iran were the immediate trigger. But the rally’s foundations went deeper — to global supply shocks that are intensifying fears of a commodity-driven inflation resurgence.

A recent move by Mexico to slash its crude exports is compounding a global squeeze, prompting refiners in the US — the world’s biggest oil producer — to consume more domestic barrels. American sanctions have stranded Russian cargoes at sea, with Venezuelan supply a potential next target. Houthi rebel attacks on tankers in the Red Sea have delayed crude shipments. And despite the turmoil, OPEC and its allies are sticking with their production cuts.
