Fed's Warsh cites AI productivity gains while withholding rate hike guidance.
Context
What happened: Fed chair Kevin Warsh said the global economy has held up better than he expected and called AI the biggest economic shift he has seen, while giving no signal on the Fed's next rate decision, due 28 October.
Key numbers: September hike took rates to 3.75-4%. September CPI 3.7%, core 2.6%.
Why it matters: Warsh kept his pledge not to prejudge meetings, leaving markets to price the October decision. He said AI investment is currently pushing prices up, while expecting it to raise productive capacity over time, and warned the road ahead is likely to be very bumpy.
