Why the Interest Rate Freeze? Oil and Micron Shake the New York Stock Market

On the 19th local time, New York’s stock market closed slightly lower despite the Fed’s decision to keep its benchmark rate unchanged. The Dow fell 0.4% to 46,021.43, the S&P 500 dipped 0.27% to 6,606.49, and the Nasdaq declined 0.28% to 22,090.69. Renewed concerns over a prolonged period of high interest rates followed the Fed’s hawkish hold, which signaled only one rate cut this year.

The day before, the Fed left the federal funds rate at 3.50–3.75%, citing significant uncertainties around the conflict in Iran and inflation, and maintained a cautious stance. Public pressure from former President Donald Trump for an “immediate rate cut,” along with debates over political interference and central bank independence, has further weighed on investor sentiment.

On the corporate side, Micron reported second-quarter adjusted EPS of $12.20 and revenue of $23.86 billion—well above market expectations—yet its shares slid more than 4% intraday, triggering a broader correction across the semiconductor sector. With AI-driven memory demand having already set expectations high, worries over a cycle peak prompted a wave of profit-taking.

Globally, fears of Middle Eastern crude supply disruptions amid the Iran conflict remain pronounced. WTI and Brent crude jumped into the high $90s to around $100 per barrel, reviving concerns about renewed inflationary pressures in the coming months. Iran’s missile and drone attacks on Saudi refineries and rising tensions in the Strait of Hormuz remain key risk factors driving oil prices higher.
