U.S. stocks rebounded Monday after enduring three consecutive weeks of losses, with the S&P 500 closing at its lowest level of 2026, as oil prices pulled back from a critical $100-per-barrel threshold amid escalating geopolitical tensions. The market’s fragile recovery unfolded against the backdrop of President Donald Trump’s recent military strikes on Iranian assets and growing uncertainty over a U.S.-led coalition to reopen the Strait of Hormuz, a vital shipping corridor responsible for nearly one-fifth of global oil supply. While equities ended the session higher, volume remained subdued, underscoring investor caution in an environment where ‘the fog of war’—as one strategist noted—continues to cloud economic outlooks.
Markets Stage Tentative Rebound After Three-Week S&P 500 Losing Streak
U.S. equities closed higher on Monday as investors sought to stabilize after the S&P 500 suffered its worst performance since mid-2025, dropping to 6,699.38—a level last seen during the first quarter sell-off. The Dow Jones Industrial Average advanced 387.94 points, or 0.83%, to finish at 46,946.41, while the Nasdaq Composite rose 1.22% to 22,374.18. The Russell 2000, a bellwether for small-cap sentiment, outperformed with a 1.5% gain. Despite the gains, trading volume on both the New York Stock Exchange and Nasdaq fell well below seasonal averages, a sign that conviction behind the rally remained tepid.
All 11 S&P 500 Sectors End the Day in Positive Territory
The broad-based advance saw every sector in the S&P 500 finish in the green, led by a 1.6% gain in information technology. Consumer discretionary stocks followed closely with a 1.5% rise, while communication services added 1.1%. The rally capped off a volatile stretch in which the S&P 500 had fallen 4% below its January all-time high, a drawdown that analysts attributed to geopolitical risks rather than underlying economic deterioration. ‘Investors are staying put because things change quickly,’ said David Krakauer, vice president of portfolio management at Mercer Advisors. ‘In the fog of war, you can’t make long-term decisions.’
Oil Prices Retreat from $100 as U.S. Signals Easing in Strait of Hormuz Tensions
West Texas Intermediate crude oil dropped 5.28% to $93.50 per barrel on Monday, pulling back from overnight highs above $100 after the U.S. signaled potential easing in regional tensions. Brent crude, the international benchmark, fell 2.84% to $100.21, having briefly surged past $100 for the first time since 2022 last week. The volatility followed conflicting signals from the White House and Treasury Secretary Scott Bessent, who told CNBC that the U.S. would allow Iranian oil tankers to pass through the Strait of Hormuz. A subsequent report in The Wall Street Journal suggested the administration was preparing to announce a multinational coalition to escort vessels through the strait, though President Trump later implied the alliance was still in formation.
Strait of Hormuz: The World’s Most Critical—and Most Volatile—Oil Chokepoint
The Strait of Hormuz, a narrow 21-mile-wide waterway between Iran and Oman, serves as the sole maritime route for roughly 20% of the world’s oil supply. Disruptions in the strait—whether due to military conflict, sabotage, or political maneuvering—have historically triggered sharp spikes in global oil prices. In recent weeks, Iran’s blockade threats and the U.S.-led retaliatory strikes on Kharg Island, an Iranian oil hub, have effectively halted commercial traffic through the strait. Energy analysts at Goldman Sachs and JPMorgan now warn that sustained disruptions could push Brent crude toward $150–$200 per barrel, levels last seen during the 1979 oil crisis. ‘We wouldn’t be surprised if oil hits $200,’ said one Houston-based trader. ‘The longer this goes on, the harder it is to unwind.’
Trump’s Mixed Signals Complicate Coalition Efforts to Reopen Shipping Lane
President Trump’s public remarks on Monday added to market uncertainty, as he suggested that not all nations were eager to join a U.S.-led effort to protect oil tankers in the Strait of Hormuz. ‘We have some that are really enthusiastic. They’re coming already,’ Trump told reporters at the White House. ‘We’ll give you a list. Some are very enthusiastic, and some are less than enthusiastic.’ He singled out long-standing U.S. allies, including France, urging more robust participation. ‘I think [Emmanuel Macron] is going to help,’ Trump said, while also acknowledging that ‘one or two’ countries may decline to participate despite decades of U.S. protection. Analysts at Eurasia Group noted that geopolitical fragmentation could undermine the coalition’s effectiveness, leaving the strait vulnerable to further disruptions.
Tech Stocks Lead as Meta and Nvidia Move on Layoff and AI News
Technology stocks drove much of Monday’s gains, with the sector rising 1.6% as investors parsed corporate developments at Meta and Nvidia. Shares of Meta Platforms advanced more than 2% after Reuters reported the company was considering laying off 20% or more of its workforce to offset spiraling artificial intelligence infrastructure costs. A Meta spokesperson dismissed the report as ‘speculative,’ though internal documents reviewed by CNBC suggested the company had explored workforce reductions as part of a broader cost-cutting initiative. Meanwhile, Nvidia shares climbed 2% ahead of CEO Jensen Huang’s keynote address at the company’s annual GTC conference in San Jose, where analysts expected updates on the next generation of AI chips and the sustainability of the AI spending boom.
Peloton also surged 4.5% after announcing a new commercial series targeting high-traffic gyms, a move seen as a pivot toward B2B revenue streams amid ongoing struggles in its core fitness equipment market. The company’s stock had plummeted 70% over the past two years as competition in the connected fitness space intensified.

The Geopolitical Backdrop: How the Iran Conflict Is Reshaping Energy and Markets
The current market turbulence traces its roots to the escalation of the U.S.-Iran conflict in early March 2026, when Iran began restricting tanker traffic through the Strait of Hormuz in response to U.S. sanctions and military strikes. The strait, which links the Persian Gulf to the Gulf of Oman, handles approximately 17–21 million barrels of oil per day—roughly 20% of global supply. Iran has periodically threatened to close the strait since the 1980s, most notably during the Iran-Iraq War, when it mined shipping lanes and attacked vessels. The Biden administration had previously attempted to negotiate de-escalation, but President Trump’s more assertive posture—including the March 14 strikes on Kharg Island—has raised the stakes. Energy analysts at the International Energy Agency (IEA) estimate that even a temporary closure of the strait could remove 5–10 million barrels per day from global markets, triggering a supply shock comparable to the 1973 oil embargo.
What Comes Next? Scenarios for Oil, Stocks, and Geopolitics
Markets are now pricing in a range of scenarios for the coming weeks. The most bullish case assumes a rapid de-escalation, with Iran allowing tanker traffic to resume and a U.S.-led coalition successfully escorting vessels through the Strait of Hormuz. Under this scenario, oil prices could stabilize around $80–$90 per barrel, and equities might rebound further. A mid-range scenario, favored by many strategists, envisions a prolonged standoff with periodic disruptions—keeping oil in the $90–$110 range and stocks range-bound. The most bearish outcome involves a full-scale closure of the strait, which would likely push Brent crude above $150 per barrel and trigger a global recession. ‘The market is pricing in a high-probability event of a prolonged standoff,’ said Sarah Hunt, chief market strategist at Alpine Macro. ‘But it’s not pricing in the tail risk of a closure—yet.’
‘The market really feels that Trump has the market's interest, I think, in his mind long term,’ said David Krakauer, vice president of portfolio management at Mercer Advisors. ‘It still is somewhat relying on thinking that he can end this if he really wants to if things start to get bad.’
Why the Federal Reserve’s Response Could Be the Ultimate Wildcard
Amid the geopolitical maelstrom, investors are also watching the Federal Reserve’s next moves. The central bank has kept its benchmark interest rate at a 23-year high since July 2025, citing persistent inflationary pressures from energy costs and supply chain disruptions. If oil prices remain elevated or spike further, the Fed could be forced to delay or reverse its projected rate cuts, which have underpinned the stock market’s resilience over the past year. According to the CME FedWatch Tool, traders are now pricing in a 60% chance of a rate cut in June 2026, down from 80% at the start of March. ‘The Fed is in a bind,’ said Michael Feroli, chief U.S. economist at JPMorgan. ‘If inflation reaccelerates due to oil, they can’t cut rates without risking a de-anchoring of expectations. But if they hold, they risk choking off growth.’
Frequently Asked Questions
Frequently Asked Questions
- Why did oil prices spike above $100 per barrel last week?
- Oil prices surged above $100 per barrel after Iran began restricting tanker traffic through the Strait of Hormuz in response to U.S. military strikes on its oil infrastructure. The strait handles 20% of global oil supply, and any disruption raises fears of a supply shortage. Traders also cited broader concerns over inflation and geopolitical risk premiums.
- How could the Strait of Hormuz conflict affect gasoline prices in the U.S.?
- If the strait remains closed or traffic is disrupted, oil prices could surge, leading to higher gasoline prices at the pump. The U.S. Energy Information Administration estimates that even a temporary disruption could add 15–20 cents per gallon to national average gas prices, which currently stand near $3.50 per gallon.
- What would happen to the stock market if oil hits $200 per barrel?
- A $200-per-barrel oil price would likely trigger a sharp sell-off in equities, particularly in energy-intensive sectors like transportation and industrials. It could also force the Federal Reserve to pause or reverse interest rate cuts, further pressuring growth stocks. Analysts warn that such a scenario could push the S&P 500 down by 10–15% from current levels.
