【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 Maltese-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 began, Iranian intelligence personnel indirectly contacted the CIA to discuss conditions for 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.

Market focus is on Iran’s successor’s stance and whether the U.S. and Israel will intensify bombing.

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

U.S. stocks opened higher, with midday gains of 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 slight reductions in supply can drive oil prices sharply higher. Whether prices can stabilize afterward 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 blocked 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.

Trump announced that he has ordered the U.S. International Development Finance Corporation (DFC) to provide political risk insurance and guarantees at very reasonable prices for all maritime trade in the Gulf region, especially energy shipments. This service will be available to all shipping companies.

He also said that if necessary, the U.S. Navy will begin escorting oil tankers through the Strait of Hormuz as soon as possible.

“Regardless, the U.S. will ensure that energy flows freely to the world. America’s economic and military strength is the strongest on Earth—more actions are coming.”

The dollar index rose as much as 1.3% but settled to a 0.7% gain, at 99.04. The 10-year U.S. Treasury yield remains around 4%. Gold prices continued to decline, down 4.3%, at $5,094.87; silver fell 8%, to $82.23.

Manulife analysts believe that the recent rise in global bond yields may reflect market concerns about a resurgence of inflation and worries about future central bank decisions. However, if the conflict lasts more than a few weeks, its impact on markets and the economy could become more significant.

Pictet Wealth Management in Switzerland said that in the very short term, the Iran war will negatively impact stocks due to geopolitical uncertainty and soaring oil prices. But history shows such events are usually short-lived, and investors should continue prioritizing tangible assets—including gold, metals, and other commodities.

They noted that if the conflict remains short-term, oil prices could fall back to pre-crisis levels, with overall macroeconomic impact remaining limited. However, in the short term, central banks may adopt a more cautious stance. The Federal Reserve might delay future rate cuts, depending on the duration and severity of the conflict. As long as the scope of the conflict remains limited, the dollar could strengthen temporarily, given the U.S.’s relative energy independence. If new oil shocks occur, markets may see the U.S. as more resilient than Asian countries heavily dependent on oil imports.

Monday: Trump accelerates war progress, Nasdaq rises 0.4%, Anthropic “crashes,” NVIDIA jumps 3%

Due to many users switching from OpenAI to Anthropic, Anthropic experienced a crash. Since Anthropic is mainly paid, the crash reflects strong growth in paying users, likely boosting revenue, but also indicates insufficient computing power. Nvidia (US: NVDA) surged 3%, closing at $182.48, boosting the Nasdaq.

Trump held a press conference, stating that the initial estimate for the war is 4 to 5 weeks, and the current progress is far ahead of schedule. For example, they initially thought it would take 4 weeks to dismantle Iran’s military leadership, but in fact, the U.S. achieved this in about an hour. Overall, the progress has exceeded expectations. However, he did not set a time limit, “Whatever time it takes, that’s fine. Whatever is needed, we will do it.”

Israel and the U.S. continue bombing. Due to ongoing war, European and Middle Eastern countries are mediating a ceasefire, reducing war risk premiums. The dollar index rose 1%, at 98.55; gold prices rose 2.7%, reaching a high of $5,419.11, then settled to $5,325, up 0.9%. Spot silver plunged 7.7%, to $86.54. The 10-year U.S. Treasury yield remains high at 4.03%.

Under the shadow of war, the Dow once fell 599 points, low at 48,377; closed down 73 points at 48,904; the S&P rose 2 points to 6,881; Nasdaq gained 0.4%, at 22,748.

Oil prices surged, with Brent crude up 13%, reaching $82.37, then closing up 7.2% at $78.12; NY crude rose 12.4%, high at $75.33, then up 6.4% to $71.33.

Major stocks generally declined amid global turbulence, but Palantir (US: PLTR) surged 5.8% as its Ontology technology integrated satellite imagery, communication monitoring records, and other info, greatly improving decision efficiency amid US-Iran conflict.

U.S. Secretary of Defense Lloyd Austin said the duration of military actions against Tehran will be decided by President Trump.

Invesco’s Benjamin Jones expects that stock markets will decline in the short term after the conflict, but the subsequent trend depends on how the situation develops. Most impacts will be reflected through rising oil prices. Cyclical and consumer sectors may be hit harder, while defense, energy leaders, and gold mining stocks are expected to benefit from geopolitical shocks.

Key data this week will include the February unemployment rate and non-farm employment figures.
