The war in Iran has thrust the world’s major central banks into a familiar—and deeply uncomfortable—position. Just as inflation pressures were easing and policymakers were preparing to move toward rate cuts, a surge in energy prices driven by disruptions in the Middle East is complicating the global outlook. The result is a worsening policy dilemma: rising inflation risks on one side, and slowing economic growth on the other.
That trade-off will be in focus this week as several of the world’s most influential central banks hold closely watched policy meetings. Economists broadly expect these institutions to keep borrowing costs unchanged, adopting a wait-and-see stance. But the renewed energy shock—tied to attacks on infrastructure and shipping disruptions—is already shifting expectations about how quickly policymakers can move to support growth.
The timing of the conflict is particularly complicated. Officials must decide whether to treat the shock as temporary or respond more aggressively to its inflationary implications. Rising fuel costs tend to lift headline inflation and can feed into broader price pressures through more expensive goods and services, strengthening the case for keeping interest rates elevated.
At the same time, more expensive energy acts like a tax on households and businesses by squeezing disposable incomes and raising operating costs. That dynamic can slow consumption, investment, and overall economic growth—conditions that would normally argue for lower borrowing costs. One analyst from a major financial institution noted that the war increases both the risk that earlier rate cuts will be needed and the risk that a higher inflation path will delay them.
Bond markets have already begun to reflect that tension. Yields on short-dated government debt have moved higher in recent weeks as traders push back the timing of expected rate cuts in response to renewed inflation risks.
When the U.S. central bank concludes its meeting, officials are widely expected to leave the benchmark policy rate unchanged while acknowledging heightened uncertainty about the economic outlook. Updated projections are likely to reflect both stronger near-term inflation pressures and somewhat weaker growth as elevated energy costs feed through the economy.
This same dynamic is playing out even more forcefully across Europe. The European Central Bank is also expected to keep policy steady even as the energy shock threatens to lift headline inflation while weighing on activity. Its president recently stated that policymakers would not allow the region to experience a severe inflation shock like the one seen in 2022, affirming they will do all that is necessary to ensure price stability.
Elsewhere, officials face what may be an even more stark backdrop. Rising fuel costs have increased upside risks to inflation, reducing the likelihood of an imminent rate cut despite clear signs of a cooling labor market and stagnating growth. Even in nations where inflation has remained comparatively subdued, the outlook is shifting as higher energy prices feed into consumer costs, tilting the balance of risks toward higher inflation if the shock intensifies.
