Warsh Flags AI-Driven Inflation Risks Amid Global Tightening

Federal Reserve Chairman Kevin Warsh described an economy facing immediate upward pressure on prices from artificial intelligence spending and energy costs, even as he projected longer-term productivity improvements from the technology. Markets showed little reaction to his remarks at the IMF-World Bank meetings in Bangkok. Warsh declined to preview the October policy decision, stating he does not prejudge meetings and that the Fed no longer supplies forward guidance. He characterized recent moves by central banks as a synchronous tightening that leaves no free riders on inflation control. Surging energy costs tied to the Iran war and the AI investment boom are contributing to higher borrowing costs worldwide, while global public debt approaches levels last seen after World War II. The U.S. has maintained that strong growth will address its own rising debt burden. Warsh expressed optimism that AI will ultimately make adopting economies wealthier, yet he described the transition path as very bumpy with uncertain near-term effects on employment. He said a decade from now the developments would be viewed as hugely consequential. The Fed raised rates to a 3.75-4 percent range last month. Traders currently assign a 72.3 percent probability to no change at the late-October meeting and anticipate a possible December hike, according to CME FedWatch data. Goldman Sachs economists interpreted the comments as consistent with an October pause followed by one final increase.
