This represented a stark turnaround from Monday’s trading. Stocks had bounced back from significant midday declines to finish mostly in positive territory, with the S&P 500 recording its largest intraday rebound since November.
The premarket sell-off on Tuesday was more widespread and persistent.
Oil Spikes as Strait of Hormuz Concerns Mount
Oil prices surged over 6% after tankers started bypassing the Strait of Hormuz, a vital passageway for worldwide oil shipments. Brent crude advanced to $82.64 a barrel, a gain of 6.3%, while West Texas Intermediate increased 6.5% to $75.87.
The jump in oil prices amplified inflation worries and pushed Treasury yields up. The yield on the 10-year note rose 5 basis points to 4.09%, following a 9-point increase the previous session.
Gold futures advanced 0.4% to $5,331 per ounce after an initial drop, as investors sought safe-haven assets. The US dollar strengthened 0.6% versus a basket of major currencies.
Bitcoin dropped 2.2% to $67,616, mirroring the overall shift away from risk.
President Trump intensified concerns Monday night by posting on Truth Social that the US possessed “a virtually unlimited supply” of armaments. He would not dismiss the use of ground troops, vowing “whatever it takes,” and indicated the war might last “far longer” than the original four-to-five-week projection.
Corporate Earnings Still in Focus
Amid the geopolitical turmoil, the earnings season proceeded. Target’s stock moved higher premarket after reporting holiday and annual sales that aligned with Wall Street expectations. Financial reports from Ross Stores, , and Best Buy were also scheduled for Tuesday.
Deutsche Bank analyst Jim Reid noted that the direction of markets would depend on oil price movements. “Any sustained spike would undoubtedly trigger a more meaningful risk-off move,” he stated, “but without that, markets are likely to revert fairly quickly to focusing on macro data and AI-related themes.”
As of Tuesday morning, Dow futures were lower by 744 points at 48,201, S&P 500 futures were at 6,780, and Nasdaq 100 futures traded at 24,521.
