The S&P 500 came under selling pressure on July 8, 2026, after US President Trump declared the Memorandum of Understanding (MoU) with Iran a failure. The surprising turn in peace negotiations between the US and Iran triggered a market reaction that spread across multiple asset classes.
Geopolitical Tensions Drive Crude Oil Prices
Middle East tensions led to disruptions in the Strait of Hormuz, one of the world's most critical shipping routes for crude oil transport. As a result, crude oil prices rose sharply on July 8, 2026. Market observers see impacts on gold, the US dollar, interest rates, and stocks in the artificial intelligence and semiconductor sectors.
Analysts are positioning constructively toward US domestic energy and physical gold to capture geopolitical risks and de-dollarization trends.
Technology Sector Under Pressure: Micron in Bear Market
Alongside geopolitical uncertainties, weakness in the technology sector intensified. Micron Technology officially entered a bear market on July 8, 2026 – a term describing a price decline of at least 20 percent from the most recent peak.
Nvidia is also showing notable valuation shifts: Despite strong earnings in artificial intelligence, the chip maker's forward multiple reached a level not seen since 2019. The forward multiple is a valuation metric that puts the current stock price in relation to expected earnings over the next twelve months.
Fed Minutes and Consumer Sentiment in Focus
Beyond geopolitical developments, market attention is turning to the Federal Reserve's release of minutes from the recent FOMC meeting. The Federal Open Market Committee (FOMC) sets US monetary policy and publishes minutes after each meeting that provide insights into the discussions and economic assessments of central bankers.
At the same time, signs are mounting of weakness among US consumers and in the broader economy, which is adding to market uncertainty. Some investors are already positioning for a possible sell-off in the third quarter.
Market Outlook: Volatility Expected to Persist
The combination of geopolitical tensions in the Middle East, weakness in key areas of the technology sector, and uncertainties regarding US monetary policy creates a volatile market environment. Beyond developments in the Iran conflict, analysts are primarily monitoring valuations in the semiconductor sector and Federal Reserve minutes to gauge the further direction of the S&P 500.
The Strait of Hormuz remains a critical factor for global energy markets: approximately one-fifth of globally traded crude oil passes through this waterway between Iran and the Arabian Peninsula. Any escalation in the region thus has immediate impacts on energy prices and inflation expectations.
