Donald Trump’s war against Iran may be over, but the repercussions for global monetary policy are here to stay.
With a shaky ceasefire largely holding following the US president’s onslaught in the Middle East, the path for central bank interest rates around the world has now shifted higher for years to come, according to Bloomberg Economics.
Its forecasts for borrowing costs, compiled here, show trajectories elevated by as much as half a percentage point or more through 2028 compared with those envisaged before the war. That’s both on BE’s global gauge for rates, and its measure for advanced economies.
That outlook reflects evolving inflation risks, including those that might arise from the race to adopt artificial intelligence, which may yet subside. Even so, price momentum is still lingering from the energy shock caused by the closure of the Strait of Hormuz.
With the dust settling from the conflict, BE’s forecasts showcase how the immediate cost-of-living impact on consumers and businesses will now be compounded by a period of more expensive loans and mortgages than might otherwise have been the case.
Earlier this year, BE predicted the Federal Reserve’s rate would end up a percentage point lower by the middle of 2027, instead of the single quarter-point reduction currently envisaged. The European Central Bank is anticipated to hike again to a level half a point higher than originally envisaged, before then easing in due course.
BE’s outlook also suggests that the global economy is proving able to withstand more elevated borrowing costs, pointing to its capacity to weather repeated shocks.
But given Trump’s appetite for disruption, with the war having followed last year’s campaign to raise US tariffs, that resilience will surely be tested again before long.
With that caveat in mind, here is the quarterly guide by Bloomberg Economics to the monetary policy of 23 central banks, accounting for a combined 90% of the global economy.
