Market expectations for a September Fed rate hike dropped sharply to 30%, boosting the Nasdaq and S&P 500 while the Dow slipped.
What happened
The odds of the Federal Reserve raising interest rates in September fell to just 30%. This triggered a split in pre-market futures, with the tech-heavy Nasdaq 100 and S&P 500 rising while the Dow Jones Industrial Average slipped. Exchange-traded funds broadly moved higher. The re-pricing shifted roughly 500 billion dollars in market value.
Why it matters
Lower rate expectations reduce the discount rate used to value future corporate earnings, which disproportionately lifts growth and technology stocks in the Nasdaq 100. It also eases pressure on bond yields, making equity risk more attractive. The split with the Dow suggests investors are rotating out of rate-sensitive industrial names and into longer-duration assets.
The case against
A 30% probability is not zero, and a single hot inflation print could quickly reverse these bets. The futures move is a pre-market reaction to a sentiment shift, not a confirmed policy pivot, and thin liquidity can exaggerate the price action before the opening bell.
What settles it
Whether the 30% September hike probability holds or reprices through the day, especially after any Federal Reserve commentary or economic data releases.
