Dow tumbles 900 points as losses accelerate ahead of Fed decision: Live updates

Market turbulence began as investors braced for the Federal Reserve’s impending interest rate decision, leading to a broad selloff across major indexes. The Dow Jones Industrial Average fell 900 points, while the S&P 500 and Nasdaq also trended lower. These declines occurred alongside a surge in oil prices, contributing to widespread market volatility throughout the trading session.

Contributing factors identified across financial reporting include specific concerns regarding geopolitical tensions involving Iran and former President Trump. The semiconductor sector faced significant pressure, with Micron, Marvell, and SK Hynix emerging as notable movers. Microsoft was also identified as a company experiencing significant stock movement during the downturn.

As of July 30, 2026, the focus remains on the Federal Reserve’s official announcement. Investors are simultaneously tracking the impact of these geopolitical developments on major tech earnings and oil prices. Future market movement depends on the specifics of the central bank's policy decision and the continued reaction of the equity markets to the existing global climate.
