The Fed announced its sixth consecutive rate hold on Wednesday afternoon, with Fed Chair Jerome Powell striking a far more aggressive tone than markets had priced in during his post-meeting press conference. Powell noted that progress on lowering U.S. inflation to the central bank’s 2% target has stalled dramatically in the first quarter of 2024, adding that policymakers have no clear timeline for interest rate cuts, directly pushing back against widespread market expectations for a cut as early as June. Following Powell’s remarks, market pricing for a June rate cut collapsed from 62% probability to less than 8%, with most investors now pushing their rate cut forecasts to September or even the end of 2024. Just hours after the Fed’s announcement, multiple verified reports broke that Israel had launched a targeted military strike on Iranian military and nuclear facilities inside Iranian territory, marking a major escalation in the ongoing conflict between the two regional powers and triggering immediate concerns over potential disruptions to global energy supplies. The dual shocks sent U.S. stocks plunging at the opening bell on Thursday: the Dow Jones Industrial Average fell 431 points, or 1.12%, by midday trading, the S&P 500 dropped 1.34% to its lowest level in nearly two months, and the tech-heavy Nasdaq Composite slid 1.76% as high-growth tech stocks, which are particularly sensitive to elevated interest rates, led the broader market sell-off. Major tech names posted steep declines: Apple fell 2.23%, Microsoft dropped 1.91%, and AI chip leader NVIDIA tumbled 2.87% as investors rotated rapidly out of risk assets. On the flip side, energy stocks outperformed the broader market as Brent crude oil prices jumped 3.6% to above $89 per barrel, with ExxonMobil rising 1.47% and Chevron gaining 1.62%. Defense contractors also rallied on the geopolitical tensions, with Lockheed Martin climbing 2.44% and Northrop Grumman up 2.18%. Safe-haven assets saw massive inflows, with spot gold prices rising 1.28% to above $2365 per ounce and the CBOE VIX Volatility Index, widely known as Wall Street’s “fear gauge”, spiking 22% to above 19.2, its highest level since late October 2023. Market strategists warn that the dual pressures of higher-for-longer interest rates and escalating geopolitical risk in the Middle East are likely to keep volatility elevated for U.S. stocks in the coming weeks, with investors now closely monitoring updates on the Iran conflict and upcoming U.S. consumer price index data for further clues on the Fed’s next policy moves.
