In the marble corridors of the Federal Reserve’s Washington headquarters, where the language of monetary policy tends toward careful, almost geological deliberateness, the past several weeks have felt noticeably different. Rate cut timelines that were being mapped in January have been quietly folded and put away. Meeting agendas that anticipated a relatively smooth 2026 are being reconsidered. The war in Iran, which began on February 28, has done what geopolitical events rarely manage to do so cleanly: it has disrupted the plans of the most powerful central banks on earth simultaneously, and left their policymakers navigating something that their standard models were not built to handle.
Oil crossed $100 a barrel after U.S. and Israeli military operations began, and it has stayed there. Some analysts see a path to $150 if the conflict continues at its current intensity. The Strait of Hormuz blockage has cut off approximately a third of the world’s seaborne fertilizer, with food prices beginning to move. Gas prices in the United States climbed more than $1 a gallon in the weeks following the first strikes, and economists at Bank of America now project that Consumer Price Index inflation could approach 4 percent year-on-year by the second quarter — up from a pre-war estimate of 3 percent. That shift, modest as it sounds in percentage terms, is carrying serious consequences for monetary policy decisions that affect borrowing costs for hundreds of millions of households.

The problem that central banks are confronting is not simply that inflation is rising again. It’s that this particular inflation is hard to fight with the tools they have. Jerome Powell said as much directly in late March, noting that monetary policy is poorly suited to addressing supply-side price shocks — the kind that come from energy disruptions and transportation bottlenecks rather than from excess consumer demand. Raising interest rates reduces spending and cools an overheated economy. It does nothing to open a blocked shipping channel or replace a curtailed oil supply. The Fed’s traditional remedy may be, in this specific context, mostly ineffective — and applying it aggressively could cause a recession without actually bringing prices down. That’s the scenario that has policymakers looking genuinely unsettled.
Watching how quickly market expectations shifted is instructive. At the start of 2026, traders were confidently pricing in several Federal Reserve rate cuts through the year, part of a broader narrative that the post-COVID inflation cycle had been decisively tamed and the tightening era was winding down. That narrative is now considerably less tidy. A gauge of Treasuries has erased its year-to-date gains as bond yields pushed higher, reflecting investor concern about a widening U.S. budget deficit and renewed inflation risks. Bets on Fed easing have eroded. Traders are now pricing in possible rate hikes — not cuts — in the United Kingdom and the eurozone later in the year. The central bank meeting that convened in mid-March was the first since the war began, and the gap between what the pre-conflict consensus expected and what policymakers are now facing was considerable.
The historical parallel that keeps surfacing in economic discussions is 1973–74. The OPEC oil embargo sent energy prices into territory that economies at the time had no framework for managing. Inflation reached levels not seen since before World War II. The Dow Jones fell roughly 40 percent. Central banks, which had spent decades focused primarily on demand management, found themselves almost helpless against a supply shock of that magnitude. The policy mistakes of the 1970s — letting inflation expectations become unanchored, tightening too late, then too aggressively — took a decade and a painful recession to correct. The Paul Volcker era, which broke inflation’s hold through interest rates that hit 20 percent, caused genuine economic suffering before it worked. Nobody wants a repeat. But the structural similarity between that period and this one — an external supply disruption generating cost-push inflation that demand-management tools can’t easily reach — is uncomfortable to ignore.
There’s a sense, talking to economists and reading the careful language of central bank statements, that the institutions themselves are being honest about the limits of their frameworks in a way that would have seemed unusual two years ago. The Bank of England is reportedly split on the right course. The ECB is navigating competing political pressures across eurozone member states, some of which have right-wing governments temperamentally hostile to the bank’s independence. The Fed is watching oil, watching food prices, watching Treasury markets, and trying to determine whether what it’s seeing is a temporary shock that will resolve when the conflict ends or something more durable that reshapes the inflation environment for years. Nobody has a confident answer to that question yet, which is itself a significant departure from the relative clarity that characterized monetary policy even eighteen months ago.
It’s still unclear whether the conflict’s duration, a negotiated resolution, or the opening of the Strait of Hormuz will change the calculation faster than rate decisions can. What seems certain is that the calm confidence of the post-COVID disinflation story has been interrupted, perhaps decisively, and the institutions responsible for price stability are operating with considerably less certainty than their public statements typically convey.
