Global Markets - Stocks Break AI-Driven Rally; Powell's Caution Tempers U.S. Yields

GLOBAL MARKET - NEW YORK. Wall Street stock indexes broke a three-day string of artificial intelligence-fuelled records on Tuesday, and U.S. Treasury yields slid after Federal Reserve Chair Jerome Powell indicated a cautious approach to the next U.S. interest rate decision.

The central bank head offered few hints as to when the Fed might repeat last week's move to cut interest rates, and emphasised how delicate the balance is between balancing the threat of inflation with signs of weakness in the labor market.
