Wall Street suffered steep losses on Thursday, March 26, 2026, as surging oil prices and deepening uncertainty over the U.S.-Iran conflict rattled investor sentiment. The Nasdaq Composite officially closed in correction territory — down more than 10% from its October 2025 high — while the broader market extended its retreat on fears that the four-week-old Middle East war may drag on far longer than anticipated.
U.S. Market Closing Summary

The sell-off was broad-based: declining stocks outnumbered advancers by a wide margin on both the NYSE (1,989 vs. 791) and Nasdaq (3,428 vs. 1,402), according to MarketWatch. Total volume across both exchanges topped 12.9 billion shares.
Nasdaq Enters Correction Territory
The Nasdaq Composite closed down 2.38%, falling more than 10% from its 52-week intraday high set on October 29, 2025. This marks the index’s worst day since November 2025 and confirms a technical correction. The Nasdaq 100 fell 2.38% to 23,587, led by sharp declines in mega-cap tech names.
“I think we’re headed lower in the medium term until we get some more certainty,” Adam Parker, founder at Trivariate Research, told CNBC’s Closing Bell. “You got to be cautious here and not take a ton of risk in the near term.”
Katie Stockton, founder of Fairlead Strategies, warned that the next support level for the S&P 500 is around 6,175 — roughly 5% below Thursday’s close — noting that a breakdown in semiconductor stocks like Micron (MU) could trigger the next leg lower.
Key Stock Movers
Meta Platforms (META) — Down ~8%
Meta Platforms was the day’s biggest headline stock, plunging nearly 8% after suffering two major court defeats in child safety trials. A jury in Santa Fe, New Mexico ordered Meta to pay $375 million in damages for misleading users about the safety of its apps for children. A day later, a jury in Los Angeles ruled that Meta and Google’s YouTube must pay a combined $6 million in a personal injury trial related to social media addiction. Timothy Edgar, a lecturer at Harvard Law School, called the rulings “a major watershed event” that “represent a big shift in how Americans are viewing Big Tech.” Meta’s stock is now down 17% year-to-date.
Micron Technology (MU) — Down ~7%
Micron Technology slid nearly 7% on Thursday, extending its decline to six consecutive sessions and falling 22% from its all-time high set just a week earlier. Memory chip stocks have been under pressure since Google’s unveiling of TurboQuant, a new AI model that cuts memory requirements. BTIG analysts noted that Micron hadn’t seen a 20% drop across six days after hitting a 52-week high since 1999. Other memory chipmakers including Sandisk (SNDK), Western Digital (WDC), and Seagate Technology (STX) also fell 2%–4%.
Brown-Forman (BF.B) — Up ~14%
Shares of the Jack Daniel’s owner surged more than 14% after Bloomberg reported that French spirits company Pernod Ricard is considering a bid for Brown-Forman.
Other Notable Movers
- Nvidia (NVDA) fell 3.7% and Alphabet (GOOGL) dropped 3.5%, weighing on the Nasdaq.
- Clear Secure (YOU) climbed 20% over two weeks as TSA lines grew during a partial government shutdown.
- Dell Technologies (DELL) hit all-time highs. Josh Brown of Ritholtz Wealth Management called it the “epitome” of a tech stock offering a hedge against AI disruption.
- Energy stocks hit new 52-week highs: ConocoPhillips ($131), Phillips 66 (all-time high), Diamondback Energy, and Coterra Energy.
- DoorDash (DASH), Lululemon (LULU), and Cintas (CTAS) all hit new 52-week lows.
Iran War, Oil Prices & Geopolitical Developments
Oil prices surged sharply on Thursday as ceasefire hopes faded. Brent crude jumped 5.66% to settle at $108.01 per barrel, while WTI crude climbed 4.61% to $94.48, according to CNBC.
The key geopolitical developments that rattled markets included:
- Iran’s foreign minister told state media that Tehran has “no intention” of holding direct talks with the U.S., even as Iran reviews an American ceasefire proposal.
- President Trump warned in a Truth Social post that Iran “better get serious soon, before it is too late, because once that happens, there is NO TURNING BACK, and it won’t be pretty.”
- Gulf states issued a joint statement condemning Iran’s strikes from Iraqi territory on their energy infrastructure, declaring readiness for self-defense.
- Iran is reportedly preparing legislation to impose tolls on ships passing through the Strait of Hormuz, a critical shipping route that has been largely paralyzed since the war began four weeks ago.
- The Pentagon is preparing to send ~3,000 additional troops from the 82nd Airborne Division to the Middle East.
Later Thursday evening, Trump extended the deadline to attack Iran’s energy infrastructure to April 6, calling the negotiations “ongoing” and “going very well” in a Truth Social post. Stock futures immediately rose on the news, with Dow futures climbing 175 points (0.4%).
OECD Inflation Warning
Adding to the bearish backdrop, the Organization for Economic Cooperation and Development (OECD) issued a stark warning in its periodic economic update, forecasting U.S. headline inflation at 4.2% for 2026 — sharply higher than the prior projection of 2.8% and well above the Federal Reserve’s own estimate of 2.7%. The OECD cited the Iran war’s disruption to global energy markets as the primary driver.
Meanwhile, a key measure of the labor market remained resilient: initial jobless claims rose by 5,000 to 210,000, in line with estimates, while continuing claims fell to 1.82 million — the lowest since May 2024.

European markets closed sharply lower, pressured by the same geopolitical headwinds plaguing Wall Street. The STOXX Europe 600 fell 1.13% to 580.84, its largest daily decline in over a week. The DAX in Germany led the decline, shedding 1.50% as Europe’s largest economy faces a growing threat from the Iran conflict to its already fragile recovery. The UK’s FTSE 100 dropped 1.33%, weighed down by surging UK gilt yields — the 10-year gilt approached its highest levels in 17 years. Sweden’s OMXS30 was the worst performer among major European indices, falling 1.82%.
Among STOXX Europe 600 constituents, top gainers included LPP S.A. (+12.69%), Vestas Wind Systems (+5.84%), and Saipem (+5.80%), while sectors tied to consumer discretionary and tech bore the brunt of selling, per MarketWatch Europe. A Bank of America strategist drew parallels between current ECB rate-hike expectations and the conditions preceding the global financial crisis.

A MarketWatch analysis warned of a “crude ticking time bomb” in April as secondary sanctions and production disruptions converge. With 40% of Russia’s oil export capacity halted and the Strait of Hormuz effectively paralyzed, supply constraints continue to intensify.
Analyst Actions & Sector Calls
- UBS downgraded Mosaic (MOS) to neutral and Nutrien (NTR) to sell on war-induced commodity disruptions.
- JPMorgan downgraded Scotts Miracle-Gro (SMG) to neutral, citing higher urea, diesel, and HDPE prices flowing through the Strait of Hormuz.
- Wells Fargo upgraded United Natural Foods (UNFI) to overweight with a $56 target (+28% upside), citing GLP-1 wellness trends and Amazon/Whole Foods exposure.
- Jefferies initiated Robinhood (HOOD) at buy with an $88 target, citing the ~$100T generational wealth transfer.

Looking Ahead
The near-term outlook remains precarious. While Trump’s decision to extend the Iran energy attack deadline to April 6 and the characterization of talks as “going very well” provided a late-session bounce for futures, fundamental uncertainty persists. As Jed Ellerbroek, portfolio manager at Argent Capital Management, told CNBC: “The market wants to go up,” but investors remain “inherently optimistic and willing to absorb bad news.”
Key themes to watch heading into the week’s final session:
- Iran ceasefire deadline: Trump extended the pause on energy facility attacks to April 6, but Iran remains defiant.
- Strait of Hormuz: Trump said Iran let 10 oil ships through as a “present” — a fragile goodwill gesture.
- OECD inflation forecast: 4.2% U.S. inflation projection could force the Fed to reconsider its rate path.
- Semiconductor sector: The memory chip selloff (Micron, Sandisk) could extend, potentially pulling the market lower.
- SpaceX IPO: Elon Musk’s company reportedly could file this week, promising a large allocation for retail investors.
