The Iran war, which began on February 28, 2026, has handed the world’s central bankers a problem they haven’t faced in years: an energy shock rippling through global markets with no clean playbook for how to respond.
Disruptions in the Strait of Hormuz, one of the world’s most critical oil chokepoints, have sent energy prices surging. And now the institutions responsible for keeping economies stable are openly admitting they don’t know whether inflation or growth will take the bigger hit first.
The ECB blinks first
The European Central Bank broke from the pack on June 11, 2026, raising its benchmark interest rate by 25 basis points to 2.25%. It was the ECB’s first rate hike in almost three years, a move that signals just how seriously Frankfurt is taking the inflationary spillover from the conflict.
ECB President Christine Lagarde framed the decision as preemptive. The goal: stamp out inflation before so-called “second-round effects” take hold. If workers start demanding higher wages to keep up with rising prices, and businesses pass those costs along, you get an inflation spiral that’s much harder to break.
Eurozone inflation hit 3.2% in May 2026, driven largely by energy costs. That number is well above the ECB’s 2% target and moving in the wrong direction.
The Fed and others sit on their hands
The Federal Reserve, Bank of England, and Bank of Japan all took a different approach. During their most recent meetings, each opted to hold rates steady.
Officials from these institutions described the economic outlook as “significantly more uncertain.” In March 2026, Federal Reserve officials cited the unclear balance between inflation and growth impacts as their primary reason for staying put.
Central banks can influence demand. They can’t reopen shipping lanes.
What the Strait of Hormuz means for everything
Roughly 20% of the world’s oil passes through the Strait of Hormuz on any given day. When that flow gets disrupted, the effects cascade quickly through energy markets, transportation costs, manufacturing inputs, and eventually consumer prices.
Central bank leaders have warned of persistent inflationary pressures as a direct consequence of the conflict. The concern isn’t just about current oil prices. It’s about expectations. If businesses and consumers start planning for sustained higher energy costs, those expectations become self-fulfilling. Prices stay elevated even after the original shock fades.
What this means for investors
The divergence between the ECB and other major central banks creates an unusual macro environment. When central banks move in different directions, currency markets tend to get volatile. A higher ECB rate relative to the Fed strengthens the euro against the dollar, all else equal, which has downstream effects on trade flows and multinational earnings.
There’s no established direct link between central bank rate decisions and crypto price action in the context of this conflict. But the broader uncertainty and inflation fears can simultaneously push capital toward assets perceived as inflation hedges, including Bitcoin.
