Global inflation surge fuels coordinated central-bank rate hikes amid energy shock

Rising prices, driven by higher energy costs from the Iran conflict, have led central banks around the world to raise interest rates, and analysts say the U.S. Federal Reserve may soon follow despite political pressure.

A fresh uptick in global inflation, largely linked to soaring energy prices from the Iran war and ongoing supply-chain bottlenecks, has triggered a series of interest-rate hikes by major central banks. The tightening cycle started with the Reserve Bank of Australia’s first of three hikes in early February, followed by Norway’s Norges Bank in May, then the European Central Bank and the Bank of Japan a month later, and the Reserve Bank of New Zealand in July.

In the United States, the annual inflation rate stood at 3.5% for the 12 months ending in June, above the Federal Reserve’s 2% target, while analysts remain divided on whether the Fed will raise rates or eventually cut them, with some predicting three cuts in 2026. President Donald Trump is pressuring the Fed to lower rates to support Republican prospects in the upcoming midterms. Economists differ on the root causes: Cato Institute fellow Jai Kedia points to higher oil prices, whereas Hoover Institute senior fellow John H. Cochrane cites unfinished pandemic-era inflation.

Central banks such as the ECB and Bank of Japan also cite the Iran conflict and a weakening yen as contributors, while Norges Bank governor Ida Wolden Bache warned that persistent business-cost increases will keep inflation elevated. The Federal Open Market Committee is slated to meet on September 15-16 to decide the next move.
