Oil Prices & Stock Market Volatility: Iran Conflict Fuels Economic Fears

Oil prices exhibited extreme volatility on Thursday, dictating market movements as fears surrounding the escalating conflict between Israel and Iran intensified. While crude prices initially surged to over $119 per barrel, they later retreated, mirroring a similar pattern in stock markets. The day’s swings underscored the precariousness of the global economic outlook as the conflict threatens to disrupt oil and gas production in the Middle East.

Brent crude, the international benchmark, briefly surpassed $119 a barrel—a level not seen since 2022—following intensified attacks by Iran on oil and gas facilities in response to Israeli strikes. This spike fueled concerns about a prolonged disruption to supply, potentially triggering a significant inflationary shock worldwide. However, Brent settled at $108.65, up only 1.2% from the previous day, and continued to ease in after-hours trading. U.S. Crude also experienced a similar rollercoaster, settling at $96.14 before falling towards $94.

The initial surge in oil prices sent shockwaves through Asian and European stock markets. Japan’s Nikkei 225 index plummeted 3.4%, while Germany’s DAX and South Korea’s KOSPI fell 2.8% and 2.7% respectively. Wall Street initially followed suit, but pared its losses as oil prices stabilized. The S&P 500 closed down 0.3%, after briefly turning positive during the final hour of trading. The Dow Jones Industrial Average dropped 0.4%, and the Nasdaq composite fell 0.3%.

Geopolitical Risk and Monetary Policy

The conflict’s impact extends beyond equity markets, significantly altering expectations for monetary policy. The surge in oil prices has effectively erased bets on interest rate cuts by the Federal Reserve in 2026. Traders are now pricing in a 73% probability that the Fed will hold rates steady or even raise them this year, a dramatic shift from just a month ago when rate cuts were widely anticipated. This change in outlook is driven by the fear that sustained high oil prices will exacerbate inflationary pressures, forcing the Fed to maintain a hawkish stance.

The Bank of Japan, the European Central Bank, and the Bank of England all held interest rates steady on Thursday, reflecting a global trend of caution amid heightened uncertainty. However, the impact of rising oil prices is already being felt in the bond market, with the two-year Treasury yield jumping before receding. Higher Treasury yields are translating into higher borrowing costs for consumers and businesses, as evidenced by a recent report showing a weakening in new U.S. Home sales.

Ripple Effects Across Asset Classes

The volatility wasn’t limited to stocks, and bonds. Gold, often considered a safe-haven asset, experienced a sharp sell-off, falling 5.9% to settle at $4,605.70 per ounce, while silver plunged even further, dropping 8.2%. Companies involved in precious metal mining were among the hardest hit on Wall Street, with Newmont and Freeport-McMoRan both experiencing significant declines. Even positive earnings reports couldn’t shield some companies from the broader market downturn; Micron Technology, despite reporting a blowout quarter, gave back some of its year-to-date gains.

A notable exception was Rivian Automotive, which rose 3.8% after announcing a partnership with Uber for the development of autonomous robotaxis. This positive news provided a rare bright spot in an otherwise turbulent trading day.

What to Watch For

The situation remains highly fluid, and markets are likely to remain volatile in the near term. A key development on Thursday evening was Israeli Prime Minister Benjamin Netanyahu’s announcement that his country would hold off on further attacks on the Iranian gas field, at the request of President Trump. While this offers a temporary reprieve, the underlying tensions remain high. Investors should closely monitor the following:

• Escalation of the Conflict: Any further military action or expansion of the conflict could trigger another surge in oil prices and a broader market sell-off.
• Oil Supply Disruptions: Continued attacks on oil and gas infrastructure, or disruptions to shipping through the Strait of Hormuz, could lead to sustained high prices.
• Federal Reserve Policy: The Fed’s response to rising inflation will be crucial. A more hawkish stance could further weigh on economic growth.
• Geopolitical Developments: Diplomatic efforts to de-escalate the conflict and restore stability in the region will be closely watched.

The Iran conflict has injected a significant dose of uncertainty into the global economic outlook. The coming weeks will be critical in determining whether this uncertainty translates into a prolonged period of economic disruption.
