The world’s biggest central banks are heading into a decisive week with an uncomfortable question hanging over them: can interest rates stay where they are if inflation is accelerating again?
Policymakers in the United States, Britain and Japan are preparing to announce rate decisions against a backdrop of volatile bond markets, rising energy costs and renewed geopolitical tensions. What was beginning to look like a gradual return to lower inflation has suddenly become much less certain.
In Washington, the biggest test may be political as much as economic. New Federal Reserve chair Kevin Warsh faces pressure from President Donald Trump, who has repeatedly called for substantially lower borrowing costs. Yet the renewed surge in oil prices could make a rate cut increasingly difficult to justify.
Crude prices recently climbed above $100 a barrel for the first time since July as disruption around the Strait of Hormuz and the Red Sea threatened global energy supplies. Although prices eased slightly on hopes of renewed negotiations, they remain significantly higher than during the summer lull in Middle East tensions.
That matters because expensive energy rarely stays confined to the petrol pump. Higher fuel and transport costs can ripple through businesses, food prices and household bills, creating another wave of inflation. US inflation was still running at 3.4% annually in the latest data, well above the Federal Reserve’s 2% target.
Warsh has already warned that policymakers still have work to do if inflation is not moving convincingly towards that target. The coming meeting will therefore be closely watched for signs of whether the Fed is prepared to resist political demands and prioritise price stability.
Britain faces a similar dilemma, although the likely immediate decision is less dramatic. The Bank of England is widely expected to leave its rate at 3.75% when policymakers meet on Thursday.
Governor Andrew Bailey has argued that higher mortgage costs have already delivered some of the economic restraint normally associated with an official rate increase. But the pressure inside the Monetary Policy Committee is growing. Three of its nine members backed a rate rise in July, while stronger-than-expected economic growth could make inflation harder to contain.
The result could be what economists describe as a “hawkish hold” — no increase this week, but a clear warning that rates could rise later if inflationary pressures persist.
Japan, meanwhile, is moving in the opposite direction from the ultra-low-rate era that defined its economy for decades.
The Bank of Japan is widely expected to raise its policy rate to 1.25% on Friday. If delivered, the quarter-point increase would take Japanese rates to a level not seen for more than three decades, marking another major step away from the country’s long battle with deflation.
The move could also reinforce the yen’s recent recovery. US Treasury Secretary Scott Bessent has openly indicated that he expects Japanese rates to rise, adding another layer of significance to the decision.
Taken together, the three meetings reveal a striking change in the global economic landscape. Central banks are no longer simply deciding when to cut rates. They are once again confronting the possibility that inflation may force them to keep rates high — or even push them higher.
The real story this week, therefore, is not just the numbers announced in Washington, London and Tokyo. It is whether central bankers can maintain control of monetary policy while oil shocks, geopolitical conflict and political pressure increasingly compete for influence.
The era of easy rate cuts may be running into an unexpected obstacle: inflation’s second wind.
