US-Iran ceasefire crumbles; oil shock fuels inflation fears

The Middle East conflict has abruptly reshaped the global risk landscape. What began as a ceasefire agreement between the US and Iran has deteriorated rapidly, with President Trump describing the situation as on 'life support' and warning of escalation. The Strait of Hormuz, one of the world's most critical oil chokepoints, is now largely shuttered; only one Russian crude cargo was loaded at Novorossiysk last week, and Qatari LNG tankers are going dark at terminals as a precautionary safety measure. This supply shock is hitting at a time when the global economy is already grappling with 3.8 percent year-over-year inflationThe rate at which prices rise across an economy., the fastest pace in several months.

Crude oil is rallying sharply. WTI is trading near $86 per barrel, and gasoline has climbed to $4.54 per gallon in the US. The cost of energy is cascading through supply chains, raising input costs for everything from fertilizer to cosmetics; Shiseido is already exploring substituting oil-based inputs with plant-derived materials as supply chains seize up. The geopolitical shock is also disrupting currency and equity markets in emerging economies. The Korea Benchmark Bond yield topped 4 percent for the first time since late 2023, as rate-hike expectations grow on energy shock fears. South Korean equities are sliding, and emerging-market currencies have weakened.

Central banks are now facing a dilemma. The ECB's Patsalides signaled that rate hikes may be necessary at the June meeting to combat heightened inflationThe rate at which prices rise across an economy. risks, effectively walking back expectations for cuts. The Federal Reserve faces similar pressure; with CPI already running hotter than consensus, a sustained oil shock could force the Fed to hold rates steady or even raise them again, erasing the cutting cycle that equities have priced in. Oil importers face margin compression while energy producers benefit from the elevated risk premium. Equity investors are caught between celebrating strong Q1 earnings and bracing for stagflationary headwinds. The US and China are managing to supply enough oil to prevent a full crisis, but any further escalation in the Middle East could quickly change that calculus.
