Hormuz blockade pushes Persian Gulf crude output 57% below pre-war levels, Goldman Sachs warns

The Strait of Hormuz has become the epicenter of a historic shipping crisis, with crude output from Persian Gulf nations already 57% below pre-war levels, according to Goldman Sachs analysts. The blockade, attributed to enforcement measures associated with the current U.S. administration's regional posture, has severely disrupted one of the world's most critical oil transit chokepoints. The scale of production decline marks a significant rupture in global energy supply chains that had long relied on uninterrupted flow through the Persian Gulf.

Goldman Sachs analysts have quantified the damage, showing that the 57% output reduction represents a multi-decade low for the region. The strait handles roughly 20% of global oil shipments daily, making even partial disruption a structural shock to world markets. Shipping insurers have raised premiums sharply, while tanker operators report increasingly circuitous routing to avoid the affected waters. The crisis has placed acute pressure on alternative transit routes, none of which can absorb the volume previously moving through Hormuz.

The implications extend beyond immediate energy markets. Asian importers, particularly those in Japan, South Korea, and China, face mounting supply uncertainty at a time of already elevated geopolitical tension. International energy traders are reassessing long-term contracts, and refineries are drawing down strategic reserves. Officials have not ruled out further escalation, warning that the situation remains fluid and that market conditions could deteriorate further before any stabilization becomes possible.
