US stocks tumbled on Monday while oil prices surged after military strikes by the US and Israel on Iran were followed by counterattacks, sending shockwaves through global markets.

The Dow Jones Industrial Average (^DJI) slumped 1.1%, or just over 500 points. Meanwhile, the S&P 500 (^GSPC) sank roughly 1%, while the tech-heavy Nasdaq Composite (^IXIC) dived roughly 1.1% as the escalating Middle East conflict spurred a retreat from risk assets.

The impact on oil prices, and in turn on inflation, is front of mind for investors already uneasy about the backdrop for stocks. The S&P 500 (^GSPC) closed February in negative territory after renewed volatility in AI and software names rattled markets.

Oil prices jumped Monday, with Brent crude futures (BZ=F) surging as much as 13% to top $82 a barrel but moderating gains to slip below $80 at last check. West Texas Intermediate futures (CL=F) traded just below $73, up around 8%. While Iran is OPEC’s fourth-largest producer, markets are also bracing for sustained disruption in the key Strait of Hormuz, where tanker traffic is at a standstill.

Shares in energy major Exxon (XOM) popped in premarket. while defense stocks including Lockheed Martin (LMT) also found buyers. But travel-linked stocks fell, with Delta Air Lines (DAL) sliding nearly 6% in the fallout.

Elsewhere in markets, gold (GC=F) jumped to top $5,400 an ounce, even as the dollar (DX-Y.NYB) rose, as JPMorgan said it expects a "risk premium" gain of up to 10% for the precious metal. Treasury yields (^TNX) moved higher as markets cut back bets on interest-rate cuts on the prospect of hotter inflation.

The next key input into those rate calculations comes Friday, with the release of the monthly jobs report. Economists expect US payrolls to have added 60,000 jobs in February, down from January’s stronger-than-expected 130,000 gain that eased recession fears.

The major US stock indexes careened into the red at the opening bell on Monday as investors fled to safe-haven assets. The tumble comes as the US-Iran conflict continues to broaden out, engulfing an increasingly large part of the Middle East.

The Dow Jones Industrial Average (^DJI) fell by 1.1%, or just over 500 points. Meanwhile, the S&P 500 (^GSPC) and the tech-heavy Nasdaq Composite (^IXIC) sank 0.9% and 0.8%, respectively.

Oil prices surged on Monday, as Brent crude (BZ=F) jumped by as much as 13% to top $82 a barrel before slightly paring back gains. West Texas Intermediate futures (CL=F) changed hands just below $73, up around 8%. While Iran is OPEC’s fourth-largest producer, markets are also bracing for sustained disruption in the key Strait of Hormuz, where tanker traffic is at a standstill.

In Europe, gas futures (TTF=F) — heavily exposed to disruption to gas flows through the Strait of Hormuz — exploded higher by more than 45%.

The dollar (DX-Y.NYB) and gold futures (GC=F) are both bid as we await the opening bell for stocks — a reminder that cash and bullion can rally together when investors scramble for safe havens.

Besides gold (and silver to a limited extent), crude oil is also surging. WTI (CL=F) is ripping on obvious supply-risk fears tied to geopolitics, and it’s dragging energy stocks higher even as most sectors are set to open in the red.

The twist: long-term US Treasurys yields (^TNX, ^TYX) are spiking as bonds are getting dumped, not bought. That’s as investors demand extra yield for longer-term risk (what's called the term premium) — plus systematic strategies dialing down longer-term (duration) exposure as volatility rises.

Geopolitical shocks often fade fast in markets, but some linger. Watch the Cboe Volatility Index (^VIX) above 20 as a gauge of institutional hedging demand (read: skittishness).

Nvidia (NVDA) said it struck two strategic partnerships with photonics companies Coherent (COHR) and Lumentum (LITE) on Monday in an effort to develop and secure access to state-of-the-art optics technology for the next generation of AI data centers.

Nvidia stock fell 1.2% in premarket trading following the announcement, while Coherent shares jumped around 8% and Lumentum stock also surged over 7%.

Nvidia agreed to invest $2 billion in Coherent to support the company's future operations as it expands its US manufacturing capabilities. As part of the agreement, Nvidia made a multibillion-dollar purchase commitment and received rights to access advanced laser and optical networking products in the future.

The Santa Clara-based company also announced a similar partnership with Lumentum, also investing $2 billion to support research & development and a new fab based in the US.

Nvidia has been rapidly scaling up its networking business and is betting that the relatively smaller photonics industry can help it make large-scale AI networks more energy efficient, reducing a bottleneck on artificial intelligence growth.

“Computing has fundamentally changed,\\" Nvidia CEO Jensen Huang said in a statement. \\"In the age of AI, software runs on intelligence with tokens generated in real time by AI factories for every interaction and every context. With Coherent, NVIDIA is pioneering next-generation silicon photonics to enable AI infrastructure at unprecedented scale, speed and energy efficiency.”

From Bloomberg:

Morgan Stanley strategists see the eruption of conflict in Iran and the Middle East as unlikely to derail their bullish view on US stocks, barring a sharp and sustained surge in oil prices.

Geopolitical risk events historically haven’t resulted in sustained volatility for US equities, the team led by Mike Wilson wrote in a note, citing the average performance of the S&P 500 (^GSPC) index in months following such episodes.

In terms of the latest Iran conflict, the bear case stems from a sharp and persistent rise in oil prices, which could compromise what the strategists see as a strengthening business cycle, the strategists said.

“Unless oil prices spike in a historically significant manner and remain elevated, recent events are unlikely to change our bullish view on US equities over the next 6-12 months,” they wrote.

Norwegian Cruise Line Holdings Ltd. (NCLH) stock fell 7% before the bell on Monday. The cruise line released its fourth quarter earnings, and despite beating analyst estimates, the group's stock fell as investors worried about the rise of oil prices driving up fuel costs. Royal Caribbean (RCL) shares also fell 5% during premarket hours today.

Berkshire Hathaway's (BRK-B) stock fell 1% during premarket hours following the release of its fourth quarter earnings on Saturday. Berkshire's operating profit after taxes fell 30% from a year ago.

American Airlines' (AAL) stock fell 5% before the bell on Monday, as the rise in oil prices caused worry among investors that fuel costs would increase.

Gold futures (GC=F) rose on Monday, trading above $5,400 per ounce as the ongoing conflict in the Middle East caused investors to move toward safe-haven assets.

Yahoo Finance's Ines Ferré reports:

Silver (SI=F) also rose, following the broader move higher in precious metals.

JPMorgan analysts expect a \\"risk premium\\" jump in gold prices in the near-term of more than 5% to 10% in the aftermath of US-Israel strikes on Iran over the weekend and counter attacks in the region.

However, those geopolitical price spikes can “can be sharp but hard to sustain,\\" said the analysts.

Gains could reverse if the conflict eases, or equity market losses prompt investors to sell assets to cover losses or raise cash. On Monday US stocks were poised to open sharply lower.

Despite the potential for short-term volatility, JPMorgan forecasts demand from central banks and investors will ultimately push gold prices to $6,300 per ounce by the end of 2026.

“A near-term boost in geopolitical risk premium is clearly aligned with our bullish view on gold, but it is far from the sole reason we remain structurally bullish on the metal,” wrote JPMorgan's Patrick Jones.

The 10-year Treasury yield is rising alongside those for US bonds more broadly, even as the spiraling US-Iran conflict sparks a risk-off mood in markets.

From Bloomberg:

US Treasuries fell as conflict in the Middle East sent oil prices soaring, stoking fear inflation will accelerate and forcing traders to scale back wagers on the scope of interest-rate cuts.

Rather than sheltering in US government debt as typically happens in times of global market turbulence, bond traders focused instead on the danger that fighting across the region reignites inflation — potentially dimming the chances of more Federal Reserve easing. US President Donald Trump, who is pushing for regime change in Iran, has said the bombing campaign could continue for weeks.

Shorter-dated bonds led the move, sending the two-year yield four basis points higher to 3.42%, while the rate on 10-year notes rose three basis points to 3.97%. Money markets shifted back the possible timing of the Fed’s next rate cut by two months to September.

“The ‘bond-as-haven’ trade becomes less clean,” if higher oil prices keep inflation pressures elevated, said Charu Chanana, chief investment strategist at Saxo Markets in Singapore.

The dollar (DX=F) rose against other currencies as high oil prices led investors to think the Federal Reserve won't cut rates soon.

Bloomberg News reports:

Bloomberg’s gauge of the dollar rose as much as 0.8% to its highest since early February following the weekend’s US and Israeli military strikes on Iran. With the effective closure of the key Strait of Hormuz driving up oil by the most in four years, the inflationary impact has swaps traders pricing 56 basis points of Fed rate cuts this year, down from 60 basis points on Friday.

“It’s probably an early sign that the market thinks the Fed will be less inclined to cut rates if this oil price surge is sustained and ultimately translates into higher US inflationary pressure,” said Gareth Berry, a strategist at Macquarie Group in Singapore. “This is contributing to dollar strength — on top of the risk-off tone — while at the same time causing some mild selling of US Treasuries.”

Tesla (TSLA) gained market share again in France and Norway in February, according to official data, in a sign of stabilization in Europe after two years of declining sales. Tesla stock fell 2% before the bell on Monday.

Reuters reports:

In France, the automaker's registrations, ​a proxy for sales, rose 55% even as most rivals sold fewer cars than a year ago.

They increased 32% in Norway, but fell 18% in Denmark, ‌the first countries ⁠to publish February data, with others including Italy and Spain set to report through ⁠the day.

Tesla saw European sales drop 27% last year amid rising competition, particularly from Chinese EV brands, ​controversy over ​Musk's politics and an ​ageing model lineup.

Last year ‌Tesla unveiled cheaper versions of its Model Y and Model 3 in the United States and Europe, which started to roll out to consumers late last year.

Airline, hotel, and defense stocks all rose Monday as investors began to react to the Iran conflict. Lockheed Martin (LMT) shares rose 7% before the bell on Monday, alongside RTX (RTX). BAE Systems' (BA.L) London shares were up 5%.

Energy companies also saw their stocks jump, with New Fortress Energy (NFE) shares rising 15% in premarket trading. oil major Equinor ASA (EQNR) rose 4%.

Bloomberg News reports:

Airlines and hotels stocks slid, while energy and defense stocks jumped, as global equities opened the week in risk-off mode following US and Israeli strikes on Iran.

In Europe, the Stoxx 600 Index fell as much as 1.9% at the the open, with hotelier Accor SA and British Airways owner IAG SA among the steepest fallers on concerns that surging fuel costs and possible airspace disruptions would hit the travel sector. By contrast, oil major Equinor ASA and UK defense contractor BAE Systems led gains in their respective sectors.

Investors are grappling with the risk that the conflict in the Middle East could disrupt global energy supplies and stoke inflation. The reaction was most pronounced in oil, with Brent crude surging as much as 13% before paring gains.

Gold (GC=F) prices catching a strong bid this morning to over $5,400 an ounce.

Helpful chart from JPMorgan showing how gold prices have reacted around prior Middle East conflicts:

The JPMorgan team sees upside potential for oil (CL=F, BZ=F) prices to $120 a barrel if the war spreads throughout the Middle East:

\\"The main risk in our view remains that the regime could lose command and control over the IRGC—as highlighted by the recent attack in Oman—which would introduce a far more unpredictable and destabilizing scenario for regional oil supply and markets. Retaliation from Hezbollah could further amplify these risks. A prolonged escalation—especially if Iran applies economic pressure—could push prices much higher. We estimate that if the conflict lasts more than three weeks, GCC oil producers would exhaust storage capacity and would be forced to shut in production. Under this scenario, Brent could trade in the $100-$120 range. Given the timeline of these unknowns, we are not making changes to our existing price forecast at this stage.\\"

No surprise here, some of the most visited ticker pages on Yahoo Finance this morning include Exxon Mobil (XOM), Lockheed Martin (LMT), Chevron (CVX) and Occidental Petroleum (OXY).

Some helpful charts from EvercoreISI on the exposures for the oil majors.

Oil (CL=F, BZ=F) prices have surged this morning post the launch of the US attacks on Iran.

Goldman thinks a good deal of upside may be left for prices:

\\"Based on the 15% weekend gain in retail prices, we estimate an $18/bbl real-time risk premium in crude oil prices, which corresponds approximately to our estimate of the fair value effect of a six-week full halt in Strait of Hormuz flows (allowing for spare pipeline capacity use as a partial offset). This estimated impact moderates to +$4 if only 50% of the flows are halted for one month. However, oil prices can rise substantially more if the market demands a premium for the risk of more persistent supply disruptions.\\"

How Goldman is thinking about the markets in the wake of the US attacks against Iran:

\\"For equities and credit the impact is negative, but only a severe and sustained oil disruption would imply substantial consequences for global growth. We expect cyclical sectors and oil importers—some of which have had strong starts to the year and may face vulnerability from positioning adjustments—will likely see pressure unless a resolution occurs quickly.\\"

President Trump said on Sunday that the bombing against Iran will continue for several weeks and called for Tehran's leaders to surrender. But Iran's security chief said it has no intention of negotiating with the US.

Blasts continued across Bahrain, Kuwait, the United Arab Emirates, and Qatar, as the Gulf states intercepted missiles launched by Iran in retaliation for the US-Israeli strikes, showing the war is spreading beyond Iran's borders. The conflict has entered its third day since US-Israeli forces began airstrikes against Iran over the weekend.

Trump is calling on Iran's leaders to hand power to the nation's people, and The Atlantic said Trump has agreed to speak with Iran's new leadership.

Bloomberg News reports:

Iran’s security chief Ali Larijani said Tehran won’t negotiate with the US, responding to reports that he had reached out to American officials through Omani mediators.

Over the past 48 hours, the Trump has made various and sometimes contradictory statements on the goals of the attack, including that it could end in a few days or last four to five weeks, and that the ultimate aim is the freedom of Iranians but also that he could cut a deal with the remnants of the Islamic Republic, though the main candidates he was considering are now dead.

At the same time, Israel, also under fire from Iran and its aligned Hezbollah fighters in southern Lebanon, launched an offensive against the group.

Yahoo Finance's Ines Ferré reports:

Bitcoin (BTC-USD) dropped below $67,000 on Sunday night after recovering from a sharp sell-off immediately following US-Israel air strikes on Iran and subsequent counterattacks in the region.

The token fell roughly 2% over the past 24 hours, as US stock futures also moved lower as the Middle East conflict rattled global markets.

The world’s largest cryptocurrency dropped to around $63,255 early Saturday amid the strikes. That same day it climbed above $68,000 as reports spread that Iran’s Supreme Leader Ayatollah Ali Khamenei had been killed.

Ether (ETH-USD) also traded near $1,950 on Sunday after tumbling roughly 10% in the wake of the attacks.

“Crypto’s resilience in the face of geopolitical escalation is constructive and suggests room for tactical upside as defensive positioning unwinds” Sean Farrell, head of digital assets at Fundstrat, told Yahoo Finance on Sunday.

However, the strategist noted that geopolitical sell-offs are typically buyable unless they lead to a more sustained economic impact, in this case through energy markets.

Bloomberg reports:

Gold (GC=F) rose, as war in the Middle East rattled markets and sent investors flocking to safer assets.

Bullion climbed more than 2% to around $5,390 an ounce in early trading, having gained more than 3% in the previous week as American troops amassed in the region. Conflict spread over the weekend after the US and Israel attacked Iran and Tehran responded with waves of missiles at targets in multiple countries. Iran’s supreme leader, Ayatollah Ali Khamenei, was killed on the first day of strikes.

Wider geopolitical tensions and US President Donald Trump’s upheaval of international relations have been key factors in a long-running rally for gold, which has also been supported by elevated central-bank buying and a wider investor shift away from sovereign bonds and currencies. The metal has gained about a quarter so far this year, despite an abrupt pullback from a record high above $5,595 an ounce at the end of January.

Bullion posted its seventh consecutive monthly gain in February, the longest streak since 1973. Even ahead of the war with Iran, Trump had adopted an increasingly aggressive foreign policy. US troops seized Venezuela’s then-president Nicolás Maduro in January and the administration made threats to annex Greenland.

Yahoo Finance's Jake Conley reports:

Oil futures surged upward on Sunday evening as traders price in the first open market session after the start of an escalating conflict in the Middle East that is increasingly threatening energy infrastructure.

Futures on Brent crude (BZ=F), the international pricing benchmark, jumped by 13% to trade above $82 per barrel in the first minutes of open trading, while those on US benchmark West Texas Intermediate (CL=F) crude, rose by nearly 10% to cross $70 per barrel.

The price on Brent marks a level not seen since January 2025 as the conflict in Iran has engulfed the entire region, while WTI reached levels not seen since 2025's \\"12-day war.\\"

Gold (GC=F) also picked up more than 2% as investors ran to the precious metal for its flight-to-safety status, while the US dollar (DX-Y.NYB) appreciated by roughly 0.3%. Shares in Saudi Aramco (2223.SR) rose by more than 3% in the Middle Eastern trading session on the prospect for higher oil prices.

Beginning early Saturday morning, the US and Israel have launched a massive barrage of air strikes into Iran in what President Trump has called a bid to destroy the country's nuclear program and potentially remove the current regime from power. Iranian Supreme Leader Ali Khamenei, who had led Iran for more than 30 years, was killed on Saturday, President Trump said in a Truth Social post.
