Mild inflation data reinforces bets that the US Federal Reserve will hold interest rates steady in September
[SAN FRANCISCO] The S&P 500 and the Nasdaq ended higher on Wednesday (Aug 12), lifted by upbeat quarterly results from CoreWeave and other artificial intelligence infrastructure firms.
This was while mild inflation data reinforced bets that the US Federal Reserve will hold interest rates steady in September.
US consumer prices barely increased in July as the cost of petrol declined for a second straight month, while underlying inflation was benign, further reducing expectations of an interest rate hike from the Federal Reserve next month.
“The numbers came in right in line. The market’s reaction is slightly positive because the market was fearful it was going to come in worse than it did. You’re seeing a market thinking that the Fed is not being pushed toward a rate hike,” said Robert Pavlik, senior portfolio manager at Dakota Wealth in Fairfield, Connecticut.
CoreWeave surged 19 per cent after the AI cloud company lifted its annual capital spending forecast and topped second-quarter earnings estimates.

The S&P 500 climbed 0.26 per cent to end the session at 7,748.50 points. The benchmark is up about 13 per cent so far in 2026.
The Nasdaq gained 0.54 per cent to 26,588.49 points for the session, while the Dow Jones Industrial Average declined 0.04 per cent to 53,770.27 points.
Eight of the 11 S&P 500 sector indexes rose, led by real estate, up 1.08 per cent, followed by a 1.06 per cent gain in information technology.
Wall Street’s fear gauge, the Cboe Volatility Index, dipped 0.8 point to 14.45, its lowest level since January.
Traders are now pricing in a 62 per cent chance of the Fed holding rates at its September meeting, according to CME’s FedWatch Tool.
Before the July inflation data was released, bets were split between a hike and no change.
The conflict between the US and Iran remained volatile as a senior Iranian source said there had been no progress in talks to revive the interim deal reached in June and define a time frame to implement it, while shipping attacks continued.
