Iran Crisis Drives Oil Premium; Dollar-Oil Correlation at Historic Highs; Hormuz Closure Persists

Eleven weeks into the Middle East conflict triggered by Iran, a critical shipping chokepoint remains disrupted, and the macroeconomic ripples are accelerating. The Strait of Hormuz, through which roughly 21 percent of global oil flows, has been partially closed or severely congested due to conflict-related shipping attacks and insurance pressures. Vitol has begun offering Iraqi Basrah crude outside Hormuz as a workaround, a sign that some shipments are navigating alternate routes, but full normalization remains elusive.

The price impact is acute. Oil prices have surged, and the linkage between the US dollar and crude prices has reached its most positive correlation ever recorded. This reflects a classic flight-to-safety dynamic: higher energy costs support nominal inflationThe rate at which prices rise across an economy. expectations, which keep the dollar bid as investors anticipate higher real rates. Simultaneously, commodity-importing nations face margin compression, while commodity-exporters like Russia, Saudi Arabia, and emerging-market oil producers see currency support.

US import and export prices jumped in April by the most in four years, driven directly by oil-market pressures tied to the Iran conflict.

India has also tightened gold import rules to defend the rupee, a defensive move that signals central banks across commodity-importing nations are bracing for sustained inflation.

The debate centres on how long the Hormuz disruption persists and whether alternative routes and increased US shale output can supply the incremental demand. Some observers point to supertankers exiting the Persian Gulf at rising rates as evidence of normalization, but the data remains tentative.
