【US Stock Market】 US Submarine Sinks Iranian Warship, NATO Intercepts Iranian Missile, Cargo Ship Breaks Through and Launches Two Missiles, Dow Jones Rises 333 Points, NASDAQ Up 1.4% (Updating)

U.S. Treasury Secretary Janet Yellen stated that the government will introduce a series of measures to stabilize oil transportation in the Persian Gulf, indicating U.S. intention to intervene in the Strait of Hormuz, which has been blocked by the Iranian Revolutionary Guard.

U.S. Secretary of Defense Lloyd Austin said that a U.S. submarine sank an Iranian warship in international waters. This is the first attack on a surface vessel by a U.S. submarine since World War II.

Oman reported that a Malta-flagged cargo ship was hit by two missiles in the Strait of Hormuz. According to sources, the ship is the SAFEEN PRESTIGE.

Turkey announced that NATO shot down an Iranian missile fired toward Turkish airspace.

The New York Times reported that on the second day after the attack, Iranian intelligence personnel indirectly contacted the CIA to discuss ending the conflict. Citing a U.S. official familiar with the contact, they expressed skepticism about whether the Trump administration or Iran was truly ready to seek a de-escalation mechanism.

Markets are watching Iran’s successor candidate’s stance and whether the U.S. and Israel will escalate bombing.

Oil prices sharply narrowed gains, with Brent crude up only 0.9% at $82.11 per barrel.

U.S. stocks opened higher, with the midday rebound over 330 points. As of 1:20 a.m. Hong Kong time, the Dow was at 48,835 points, up 333 points; the S&P 500 was at 6,874 points, up 0.85%; the Nasdaq was at 22,837 points, up 1.43%.

The U.S. dollar index fell 0.2%, currently at 98.88; U.S. long-term bond yields steadied at 4.079%; international gold prices rebounded nearly 2%, currently at $5,171.

DWS noted that Iran’s crude oil production in January 2026 is projected at 3.13 million barrels per day, accounting for about 4% of global supply. Due to short-term supply and demand inflexibility, even a slight reduction in supply can drive oil prices sharply higher. Whether prices can stabilize later depends on OPEC’s ability to fill the supply gap in time. However, Darwei Kung, head of commodities at the firm, said, “OPEC’s idle capacity is currently only about half of Iran’s total production.”

He added that if airstrikes cause ships to sink in the Strait of Hormuz, the shipping route could be closed for months, causing long-term supply disruptions. Compared to airstrikes alone, ground offensives would cause even greater damage to supply. Therefore, whether the Strait’s shipping is restricted or fully blocked, it could severely impact oil supplies.
