Wall Street’s main indexes gained on Friday after a key inflation reading came in softer than expected, boosting recent investor optimism that the Federal Reserve could lower borrowing costs next year.

The personal consumption expenditures (PCE) price index, considered to be the Fed’s preferred inflation gauge, climbed 2.6% in November on an annual basis, compared with expectations of a 2.8% rise, per economists polled by Reuters.

The core inflation figure, which excludes volatile food and energy components, rose 3.2% on a yearly basis, compared with an estimated 3.3% rise.

“This helps confirm the idea of a rate cut as early as March,” said David Russell, global head of market strategy at TradeStation.

“This data shows us that the inflationary turn happened some time ago and as we move further into the future, the base effects will continue to kick in.”

Another report showed, orders for long-lasting U.S. manufactured goods surged in November, boosted by aircraft bookings, but business spending on equipment appeared lacklustre amid higher borrowing costs.

Analysts also said light trading volumes ahead of the Christmas break could also impact moves during the day.

Traders see an 84.6% chance of at least a 25 basis point (bps) rate cut in March next year, and expect borrowing costs to be lower by 125 bps in September 2024, according to the CME FedWatch Tool.
