U.S. Stocks: The Nasdaq officially falls into correction territory, the worst-case scenario on Wall Street has arrived

On Thursday, the optimism from two consecutive days of gains on Wall Street was completely wiped out.

The Dow Jones fell 469 points (-1.01%), the S&P 500 plummeted 1.74%, marking the largest single-day drop in two months. The Nasdaq tumbled 2.38%, officially entering correction territory—down more than 10% from its all-time high at the end of October last year. A one-sentence summary of this day: stocks, gold, and bonds all declined simultaneously, with no assets providing effective safe-haven protection.

The first shot came from across the Atlantic. European Central Bank President Lagarde publicly dampened market optimism: she characterized the Iran conflict as a “real shock,” said “markets may be too optimistic,” and warned that inflation could force Europe to reconsider rate hikes, with economic damage potentially taking years to repair. Lagarde’s words shattered another pillar of the already fragile expectations of rate cuts.

Following closely was a heavy blow from the OECD. In its latest economic update, the organization sharply raised the U.S. inflation forecast for 2026 from 2.8% to 4.2%, well above the Federal Reserve’s own prediction of 2.7% last week. What does this number imply? It suggests that under the ongoing war’s impact, even “holding steady” has become a luxury for the Fed—market expectations for rate hikes are gradually being priced in.

On the diplomatic front, Iran’s Foreign Minister’s statements completely shattered the remaining optimistic narratives this week: Foreign Minister Abdollahian explicitly stated that conveying messages through intermediaries “does not mean negotiations with the U.S.,” Tehran is reviewing the U.S. ceasefire proposal but refuses direct contact. The Asia-Pacific markets responded first: South Korea’s Kospi plunged over 3%, Hong Kong’s Hang Seng Index fell 1.9%, and the CSI 300 dropped more than 1%.

At the individual stock level, the tech sector bore the brunt. Nvidia fell 3.7%, Alphabet declined 3.5%, and nearly all heavyweight members of the Nasdaq 100 declined. Nvidia has been under continuous pressure for weeks from geopolitical tensions and AI regulation concerns, with no signs of relief.

Within the Dow, only defensive and energy stocks like Salesforce (+1.65%) and Chevron (+1.44%) managed to stay positive, but the index overall remained dragged down, with only 9 of 30 components closing higher.

A noteworthy detail: Trump stated during a cabinet meeting that the impact of the war on oil prices and the stock market “was not as bad as I expected,” claiming “everything will come back down, even lower than before the war.” The market’s reaction was to continue falling.

Gold and Oil: Oil surges back, gold suffers its worst monthly decline since 1983

Oil: Rebound above $100, expectations of negotiations breaking down reignited

Brent crude briefly rose above $107 per barrel, WTI hovered around $93. Both benchmarks rebounded sharply from Wednesday’s lows, returning to high levels that leave the market breathless.

The driving logic remains familiar: the tough stance from Iran’s foreign minister casts a shadow over prospects for negotiations, and the market is once again pricing in a “long-term blockade.” The Strait of Hormuz’s shipping status remains fragile—shipping rates, insurance costs, and route viability are now the primary factors in oil price discovery, rather than just supply figures.

Gold: A brutal month under triple pressure

Gold futures fell 4% on Thursday, with the March decline bringing the monthly drop close to 17%, the worst since October 2008.

This phenomenon warrants careful explanation. In the face of a real Middle East war, why did gold not rise but fall? The answer points to three reinforcing logical chains: first, rising U.S. Treasury yields increase the opportunity cost of holding gold; second, the dollar continues to strengthen under the “inflation → tightening expectations → strong dollar” chain, and gold is dollar-denominated; third, inflation expectations driven by oil prices reinforce the view that “central banks will not cut rates, liquidity will not loosen,” stripping gold of its safe-haven narrative.

Gold not rising amid war is one of the most counterintuitive and warning signals in the 2026 oil price shock.

Cryptocurrency: Bitcoin falls below $70,000

Bitcoin dropped below $70,000 on Thursday, trading around $68,837, down about 3.4%. Ethereum also declined, approaching the critical support zone of $2,000 to $2,100.

This breach of $70,000 is particularly sensitive—less than a week after Bernstein loudly declared “bottom is in” last week. Currently, Bitcoin has fallen approximately 45% from its October 2022 high of about $126,000, and market confidence in a “bottoming out” is once again being tested.

An interesting structural observation: since the outbreak of war, Bitcoin’s reactions to geopolitical shocks have been gradually diminishing—initial shocks on February 28 triggered a 9% drop, the Strait of Hormuz blockade caused a 4% decline, and subsequent escalations have only caused fluctuations within 2%. This recent drop below $70,000 was driven by macro factors (ECB hawkish stance + OECD inflation upward revision), not directly by the war itself—somewhat indicating that Bitcoin’s “crisis resilience” is accumulating, but the impact of rate narratives remains significant.

After hours, a turning point emerged: Trump posted on Truth Social, announcing that the deadline to strike Iran’s energy infrastructure has been extended from this Friday to April 6, claiming “talks are ongoing and progressing smoothly.” Following the news, Dow futures immediately jumped about 205 points (+0.4%), and S&P 500 and Nasdaq 100 futures rose about 0.4%. Bitcoin also rebounded slightly from lows.

This is Trump’s Nth “after-hours market rescue” in this war—markets are seasoned enough to know this doesn’t mean the war is over, just that more time has been bought.

Summary for today: In a triple-decline pattern, Lagarde and the OECD jointly issue a global inflation warning

On Thursday, March 26, external shocks combined with technical breakdowns led U.S. stocks to their most difficult day since the war began:

U.S. Stocks: Dow -469 points (-1.01%), S&P 500 -1.74% (biggest single-day drop in two months), Nasdaq -2.38% entering correction territory. ECB President Lagarde warned markets are “too optimistic,” and OECD raised U.S. inflation forecast for 2026 to 4.2%, both accelerating the decline.

Oil/Gold: Brent back above $107, WTI around $93, oil prices surge; gold drops 4%, nearly 17% monthly decline—the worst since 2008—making gold’s failure to act as a safe haven during war the most abnormal market signal.

Cryptocurrency: Bitcoin falls below $70,000, around $68,837 (-3.4%), Ethereum under pressure; after-hours Trump delays Iran strike deadline to April 6, futures rebound, Bitcoin follows.

The market now only cares about one question: Will Tehran respond before April 6?

Trump has given Iran another window. But this time, market patience is much thinner than three weeks ago—each “extension” erodes expectations of a real ceasefire. April 6 is a new hard deadline. If Iran doesn’t respond substantively by then, Trump faces either a “credit collapse from further delays” or a “full-blown inflation crisis.”

The most costly price of this war may not be oil prices, but the market’s complete loss of faith in the next “turnaround.”
