Iran tensions and rising oil prices dampen risk appetite; DJIA, S&P 500 and Nasdaq futures retreat sharply

    US shares fell on Thursday, with the Dow down about 230 points (0.5%), the S&P 500 down 0.8%, and the Nasdaq Composite down 1.1%. Dow futures moved from about 46,200 to roughly 46,800 before slipping back towards early-session levels. Overnight, Asian markets dropped after Iran rejected a US 15-point ceasefire proposal and floated a counterproposal tied to halting strikes and control of the Strait of Hormuz. South Korea’s Kospi fell more than 3%, while China’s Shanghai index and Hong Kong’s Hang Seng each fell about 1%.

    Global Markets React To Rising Tensions

    European markets also weakened, with the Stoxx 600 about 0.8% lower as Brent crude rose above $106. Later, reports included a five-day US pause on strikes nearing expiry in 48 hours and the reported killing of the IRGC Navy commander. Gulf states issued a joint statement condemning Iran-linked strikes from Iraqi territory, and two people were killed in Abu Dhabi after debris fell from an intercepted ballistic missile. Brent rose about 5% to above $107 and WTI rose more than 4% to near $95, while the 10-year yield neared 4.4% and 20- and 30-year yields approached 5%. Tech shares fell after Google Research detailed TurboQuant, said to cut memory needs by up to six times with zero accuracy loss; Samsung fell 5% and SK Hynix 6%, while Lam Research and Applied Materials fell about 4%. Initial jobless claims rose to 210K from 205K, continuing claims fell 32K to 1.82 million, and the Fed held rates at 3.50%–3.75% with one 2026 cut projected; CME FedWatch shows an 89% chance of no change through June. With President Donald Trump’s deadline approaching, we are treating the risk of escalating conflict with Iran as the market’s primary driver. We are buying protection against a sharp downturn, as the CBOE Volatility Index (VIX) is likely underpricing the risk of a full-blown conflict in the Strait of Hormuz. Historical precedent from past Mideast crises, such as the 1990 Gulf War buildup which saw the VIX more than double, suggests volatility could spike aggressively from here. The surge in Brent crude to over $107 a barrel is a direct result of the blockade, but the real risk is a complete supply interruption. The U.S. Energy Information Administration has consistently reported that the Strait of Hormuz handles over 20% of global oil transit, so a prolonged closure could send prices significantly higher. We are therefore holding long positions through call options on WTI and Brent futures to capitalize on this upside risk.

    Portfolio Hedging And Rates Pressure

    This combination of geopolitical tension and higher oil prices creates a clear headwind for broad equity indices. We are hedging our long-term portfolios by buying put options on the S&P 500 and shorting Dow Jones futures. This defensive stance is necessary until we see a credible diplomatic resolution, as sustained high energy costs will eat into corporate profits and consumer spending. In the technology sector, the sell-off in memory chip makers like Micron and Samsung is a structural shift, not just a temporary reaction. We see Alphabet’s AI memory breakthrough as a genuine threat to long-term demand, and we are initiating short positions on key semiconductor ETFs. This sets up a classic pairs trade, allowing us to go long on the innovator, Alphabet, while betting against the companies being disrupted. Finally, we cannot ignore the Federal Reserve’s hawkish stance, which provides a challenging backdrop for the market. With jobless claims remaining low at 210,000 and the CME FedWatch tool showing an 89% probability of rates holding steady through June, there is no monetary policy cushion for stocks. The spike in the 10-year Treasury yield toward 4.4% reinforces the pressure on equities, especially long-duration growth names. Create your live VT Markets account and start trading now.
