Powell’s comments on rate cuts
Federal Reserve Chair Jerome Powell said Tuesday that signs of cooling in the labour market were a key factor behind last week’s interest rate cut, the first of 2025.
Speaking to business leaders in Rhode Island, he cautioned that the Fed faces a “challenging situation” as it works to balance strong employment with stable inflation.
Powell noted there is “no risk-free path” in the central bank’s approach, underscoring the delicate trade-offs ahead.
He also remarked that equity valuations are “fairly highly valued,” though he stressed that the current environment does not amount to “a time of elevated financial stability risks.”
Markets turned lower after his comments, with the S&P 500 ending down and snapping a three-session streak of record closes.
