Hormuz Crisis Ends Q1 With Oil Above $110, Forcing China to Accelerate Energy Diversification

The largest oil supply disruption in modern history closes out Q1 2026 with Brent at $112.78/bbl—up 63% in March alone—as the Strait of Hormuz blockade removes 10 million barrels per day from global supply, delivering a direct hit to energy-dependent Asian economies and accelerating China's strategic pivot to non-Gulf supply sources.

Following US-Israeli joint air strikes on Iran on February 28, the effective closure of the Strait of Hormuz to commercial tanker traffic since March 2 has curtailed approximately 10mb/d of Gulf production—roughly 10% of global demand. Brent surged from a February average of $69/bbl to an intra-month peak near $120, settling at $112.78 on March 30. WTI closed above $100 for the first time since July 2022, at $102.88. The S&P 500 fell 0.39% to 6,344 as energy costs pressured margins, while the VIX held elevated at 31.1. Gold hit $4,529/oz, confirming the flight to safety.

China receives 37.7% of all oil transiting Hormuz and sources over 55% of crude imports from the Middle East. Despite 1.39 billion barrels of strategic reserves (120 days of cover) and pipeline inflows from Russia, the crisis exposes a structural vulnerability: every $10/bbl rise in crude costs China's economy an estimated $35 billion annually in additional import costs. Beijing's energy self-sufficiency rate of 85% provides a buffer, but industrial margins in petrochemicals, shipping, and manufacturing are compressing rapidly. The IEA has activated the largest-ever coordinated emergency stockpile release.

Watch two triggers in the next 72 hours: first, whether the April 2 OPEC+ emergency session signals non-Gulf members (led by Russia and Nigeria) can add 1.5–2mb/d of compensatory supply. Base case (60% probability): partial de-escalation begins by mid-April as US-Iran back-channel talks resume, with Brent stabilizing in the $95–105 range. Risk scenario (25%): conflict escalation pushes Brent toward $130, triggering demand destruction across emerging Asia. For corporate treasury teams, the implication is clear: lock in FX hedges on CNH exposure and accelerate supply chain diversification away from Hormuz-dependent crude routes.
