Iran Crisis Sends Oil and Inflation Soaring; Dollar Linkage to Oil at All-Time High as Supply Routes Closed

The Middle East conflict that began roughly 11 weeks ago has fundamentally altered energy markets and broad inflationThe rate at which prices rise across an economy. dynamics. The Strait of Hormuz, through which roughly one-third of seaborne traded oil passes, has been effectively closed or severely constrained, forcing tankers to reroute through longer, more expensive channels. India condemned attacks on its vessels in the Gulf of Oman, and reports indicate that supertankers carrying unsanctioned oil are creeping higher through Hormuz despite the risks. Vitol, a major oil trader, is offering Iraqi crude outside Hormuz in a sign that some shipments are making it out, but in limited volumes and at elevated risk premiums.

US import and export prices surged in April by the most in four years, driven primarily by oil-market pressures tied to the Iran conflict. The data underscores that inflationThe rate at which prices rise across an economy. is not being imported in isolation; it is being imported through elevated energy costs that ripple across manufacturing, logistics, and consumer pricing. India's producer prices jumped to a three-and-a-half-year high in April as elevated energy prices pushed up manufacturers' input costs. The dollar's linkage to oil prices is now at its most positive ever, suggesting that traders view the energy shock as a persistent, dollar-supportive phenomenon. When oil is scarce and expensive, demand for dollars (the currency of oil trade) tends to firm.

For energy exporters, this is a windfall. OPEC+ delegates say the group aims to complete a series of oil quota increases over the next few months, returning halted production to paper by year-end if circumstances allow. TCW Group's Christopher Hays noted that the oil shock from the Iran war is set to give a lasting boost to government bonds from energy-producing developing nations. Energy importers, conversely, face margin pressure. Airlines like Singapore Airlines posted declining profits as jet fuel costs surged. Defense contractors and aerospace firms may see margin expansion if elevated energy prices drive geo-political risk premiums higher, but that is a small offset against broad-based input cost inflationThe rate at which prices rise across an economy..

The forward-looking risk is that the conflict persists or escalates, keeping routes closed and prices elevated. Traders debate whether oil can stay above $75 through 2027 given the current geopolitical reality.

If routes remain closed and energy stays expensive, central banks will hold policy tight longer, pressuring risky assets. For now, energy inflation is real, dollar upside is intact, and emerging-market exporters are seeing demand for their debt.
