The S&P 500 (SPX) fell 0.77% to 7,683 on Monday after Ackman, Rieder, and TCW's Koch warned at Delivering Alpha of higher rates and an oncoming U.S. recession.

What happened
The S&P 500 (SPX) fell 0.77% to 7,683 on Monday after Ackman, Rieder, and TCW's Koch warned at Delivering Alpha of higher rates and an oncoming U.S. recession. Ackman said the Fed made a mistake by hiking to 4.0%: with Big Tech spending $650 billion on AI this year, demand will not slow as expected, and higher rates may fuel more inflation rather than less. Rieder now expects a second hike in October and moved BlackRock's portfolio into high-grade bonds paying 7–8% instead of stocks, noting every 100-basis-point rise costs the U.S. government $130–150 billion. Koch, managing $210 billion at TCW, repeated her recession call and told investors to hold cash and agency debt rather than equities.
Why it matters
The S&P 500 is on track to finish September flat despite a 13% year-to-date gain, a signal that higher borrowing costs are beginning to bite. The 10-year yield holding above 5% for the first time since 2007 lifts mortgage rates, car-loan rates, and corporate borrowing costs across the entire economy. When three of Wall Street's most-watched money managers align publicly on higher rates and a coming recession on the same day, even confident investors have reason to take notice.
