S&P 500 Falls for Third Straight Session as Tech Flashes Death Cross; Powell Quashes Rate Hike Fears, Oil Tops $102 (March 30, 2026)
Wall Street delivered a mixed Monday session as the S&P 500 slipped 0.39% for a third consecutive losing day, while the Dow eked out a 49-point gain — its first positive session in six. The divergence was driven by a sharp tech selloff (the sector’s 50-day moving average crossed below its 200-day, flashing a “death cross”) offset by strength in financials and energy. Fed Chair Jerome Powell’s dovish remarks at Harvard knocked rate hike odds from over 50% to just 5.5%, while President Trump’s rhetoric on Iran swung from olive branch to threat of total destruction within the same Truth Social post.

U.S. Market Performance — March 30, 2026
The session told a tale of two halves. Stocks opened sharply higher — the Dow surged over 400 points at the open as markets digested Trump’s weekend rhetoric suggesting an Iran deal was near. But gains evaporated through the afternoon as the technology sector led a reversal, pulling the S&P 500 and Nasdaq into the red. Eight of 11 GICS sectors still ended higher, led by financials (+1.1%) and utilities (+0.7%). The laggards: industrials (−1.6%), information technology (−1.5%), and energy (−0.9%).
The S&P 500 now sits just over 9% below its closing high, teetering on the edge of correction territory. All three major averages have posted five consecutive weekly declines, with the Dow and Nasdaq both having already entered correction.

Powell at Harvard: “Policy Is in a Good Place” — Rate Hike Odds Collapse
In the day’s most consequential development, Federal Reserve Chair Jerome Powell spoke at Harvard University and delivered what amounted to a firm reassurance that the central bank would not react to the oil shock with higher interest rates.
“Inflation expectations do appear to be well anchored beyond the short term,” Powell said. He stressed that the Fed’s current rate target of 3.5%–3.75% is “a good place” for the central bank to observe events, including the Iran war and tariff impacts.
Crucially, Powell explained why hiking now would be counterproductive: “By the time the effects of a tightening in monetary policy take effect, the oil price shock is probably long gone, and you’re weighing on the economy at a time when it’s not appropriate.”
The market response was immediate and dramatic. Rate hike probability for 2026 plunged from over 50% to just 5.5% after his remarks, according to the CME FedWatch tool. The 10-year Treasury yield fell 9 basis points to 4.35%. Five-year breakeven rates — a market-based measure of inflation expectations — sat at 2.56% and were trending lower.
On the private credit market, Powell acknowledged rising defaults and investor withdrawals in the $3 trillion sector but said he doesn’t see “the makings of a broader systemic event.”
Powell’s term ends in mid-May, and President Trump has nominated former Governor Kevin Warsh as the next chair. However, the nomination remains stalled in the Senate Banking Committee amid an investigation by U.S. Attorney Jeanine Pirro into renovations at Fed headquarters.

Trump’s Iran Signals: Peace Talk and Total Destruction in the Same Breath
President Trump’s messaging on the Iran conflict sent investors on a wild ride Monday. On Sunday, Trump shared that Iran had accepted most of the U.S.’s 15-point plan to end the war and had agreed to allow an additional 20 oil ships to cross the Strait of Hormuz.
Then on Monday, he posted on Truth Social that “great progress has been made” in “serious discussions with A NEW, AND MORE REASONABLE, REGIME.” But in the same post, he threatened that if a deal is “not shortly reached” and the Strait is not “immediately” reopened, the U.S. would “blow up and completely obliterate all of their Electric Generating Plants, Oil Wells and Kharg Island (and possibly all desalination plants!)”
Separately, Trump told the Financial Times that his “preference would be to take the oil” in Iran and that he was considering seizing Iran’s export hub of Kharg Island — comparing it to the U.S. military operation in Venezuela earlier this year.
David Wagner, head of equities at Aptus Capital Advisors, noted a pattern: “Investors have been accustomed to this new anomaly that markets tend to do poorly on Thursday-Friday and tend to do well Monday-Tuesday.” He said cumulative returns between Thursday–Friday have lagged Monday–Wednesday by approximately 7% over the last 90 trading days, with nearly all divergence since the war began on Feb. 28.

Tech Under Siege: Death Cross, Micron Collapse, Nvidia Nears Bear Market
The technology sector was Monday’s biggest drag, falling more than 1% and flashing a significant technical warning: the sector’s 50-day moving average crossed below its 200-day moving average — a pattern known as a “death cross” that signals a potential sustained downtrend. Tech is now on pace for its fifth consecutive losing month, the longest such streak since September 2002.
The carnage in semiconductors was especially brutal:
- Micron (MU) — plunged 10%, now barely positive for 2026 after being up 60% in mid-March. The stock has fallen over 30% in just eight trading sessions, crushed by a Google AI breakthrough that traders fear could limit future memory chip demand.
- Nvidia (NVDA) — slipped 0.5%, now 21% off its all-time high, officially hovering at the bear market threshold. Trading at levels not seen since mid-July.
- VanEck Semiconductor ETF (SMH) — fell 2.8%, putting its March decline at 10.6% — the worst month since December 2022.
- AMD and Broadcom — both dropped about 3%
- Sandisk and Western Digital — both plummeted more than 9% alongside Micron

Energy Stocks Hit All-Time Highs; Aluminum Spikes on Iran Attacks
While tech crumbled, the energy sector continued its extraordinary run. Nine S&P 500 stocks traded at all-time highs on Monday — and nearly all were energy names:
Meanwhile, aluminum prices spiked after Iranian missile strikes hit critical Middle East production facilities over the weekend. Three-month aluminum on the London Metal Exchange surged 3.85% to $3,420 per metric ton, trading near a four-year high. Alcoa jumped 9% and Century Aluminum surged 11%.
On the 52-week lows side, seven S&P 500 stocks hit new lows: Boston Scientific, Insulet, Baxter International, Domino’s Pizza, Builders FirstSource, Otis Worldwide, and TransDigm — a mix of medical, consumer, and industrial names suffering from the war-induced economic slowdown.

Notable Corporate Moves
- Sysco (SYY) — plunged 15.3% after agreeing to buy Jetro Restaurant Depot for $29.1 billion, the largest deal in the wholesale food distribution space
- CrowdStrike (CRWD) — rose 2.5% after Wolfe Research upgraded to outperform and Morgan Stanley named it a top pick, saying AI increases cyber risks rather than replacing cybersecurity
- Strategy (MSTR) — the largest corporate bitcoin holder reported no new bitcoin purchases between March 23–29, snapping a 13-week buying streak
Bill Ackman (Pershing Square) pushed back against the bearish consensus, writing on X: “Some of the highest quality businesses in the world are trading at extremely cheap prices. One of the best times in a long time to buy quality. Ignore the bears.” He called the Iran war “one of the most one-sided wars in history that will end well for the U.S. and the world.”

European Markets End Monday Higher
European equities closed Monday’s session modestly higher as investors reacted to the more constructive tone from Trump’s weekend comments on Iran negotiations. The gains came before Wall Street’s afternoon tech-led reversal.
Behind the scenes, however, European fundamentals are deteriorating. Data released Tuesday morning showed euro zone inflation surged to 2.5% in March, up sharply from 1.9% in February and blowing past the ECB’s 2% target. The energy component of the CPI data swung from −3.1% in February to +4.9% in March — a dramatic reversal driven directly by the Iran war’s impact on global fuel costs.
ECB President Christine Lagarde warned last week that the central bank would respond with rate hikes if necessary. The ECB now expects 2026 GDP growth of just 0.9%, with headline inflation averaging 2.6% for the year. Meanwhile, the Financial Times reported that G7 ministers held crisis talks as the Iran war continued to roil the European economy.

Oil, Commodities & Currencies
WTI crude settled at $102.88 per barrel (+3.25%), its highest close since July 19, 2022. Brent ended at $112.78 and is on pace for the biggest monthly surge in its history, with a 55% gain in March. Oil prices were boosted by Yemen’s Iran-backed Houthi rebels firing missiles at Israel, marking the group’s first direct involvement in the U.S.–Israel war against Iran.
Traders warned that oil remains the single biggest variable for markets. Karen Firestone, co-founder of Aureus Asset Management, said that oil prices reaching $120 per barrel could prompt a recession and catalyst a slide in corporate earnings. Joseph Terranova of Virtus Investment Partners added: “You can’t take your eyes off of oil.”
In the crypto space, bitcoin ETFs posted $296 million in net outflows for the week — their first negative week since February. BTC itself is down roughly 50% from its October record.

Week Ahead: Good Friday, Jobs Report, and the War’s Next Phase
The market will be closed on Friday, April 4 in observance of Good Friday. However, the March jobs report (non-farm payrolls) is still scheduled for release that Friday morning — meaning markets will react when they reopen the following Monday.
Key data releases this week include consumer confidence and JOLTS job openings on Tuesday, followed by the employment report. All eyes remain on whether Trump’s diplomatic rhetoric on Iran translates into concrete progress, or whether the conflict escalates further. The war is now in its 31st day with no clear ceasefire in sight.
After hours Monday, Bloomberg reported that Iran struck a fully laden Kuwaiti oil tanker in Dubai waters. No injuries were reported, but the incident underscored the ongoing threat to Gulf shipping — and may weigh on sentiment when Tuesday’s trading opens.
Late Monday, the Wall Street Journal reported that Trump told aides he was willing to end military hostilities even if the Strait of Hormuz remained largely shut — a potential diplomatic breakthrough that sent futures higher in overnight trading.
