S&P 500 dips as Strait of Hormuz tensions lift oil prices

The Strait of Hormuz’s Shadow Over the S&P 500

The New York Stock Exchange saw mixed trading activity on Monday, April 23, 2026, as the S&P 500 hovered near unchanged levels, moving away from the record highs reached earlier in the month. The Dow Jones Industrial Average edged down 47 points, or 0.1%, while the Nasdaq Composite declined 0.2%. Market observers pointed to developments in the Strait of Hormuz, where tanker traffic remained limited, contributing to a 2% rise in oil prices.

Brent crude futures, the international benchmark, increased 1.7% to $107.09 a barrel, while West Texas Intermediate crossed $96. While the immediate price movements were modest, the upward trend has raised concerns among analysts. Oil prices have seen significant volatility in recent months, with fluctuations driven by geopolitical tensions. The current environment has created challenges for industries reliant on stable energy costs, including airlines and consumer goods, particularly as the Federal Reserve prepares for its next policy decision.

Adam Crisafulli of Vital Knowledge described the situation as a modest negative in a client note, though he maintained a cautiously optimistic outlook. We continue to think the conflict remains on a path of de-escalation, he wrote. However, market reactions suggested some investors remained uncertain. Gabriel Shahin, CEO of Falcon Wealth, emphasized the importance of oil price stability, stating that market calm depended on improved conditions in the Strait of Hormuz. For the moment, such stability remained uncertain.

Trump’s Brinkmanship and the Iran Proposal That Wasn’t

The weekend’s diplomatic developments began with a post on Truth Social from President Donald Trump. He canceled plans to send special envoy Steve Witkoff and Jared Kushner to Pakistan for ceasefire discussions, writing, Too much time wasted on traveling, too much work! He added, Nobody knows who is in charge, including them. Also, we have all the cards; they have none! If they want to talk, all they have to do is call!!!

The message appeared to signal a shift in U.S. strategy. Iran’s Foreign Ministry spokesperson, Esmaeil Baqaei, responded that no meeting between Tehran and Washington was currently planned, deepening the stalemate.

Later, Axios reported that Iran had put forward a proposal to reopen the Strait of Hormuz and end the conflict, while postponing discussions on its nuclear program. The White House maintained its position that Tehran’s nuclear activities remained a priority, making the offer unlikely to gain traction. Still, the report briefly lifted oil markets, highlighting how sensitive prices are to even the possibility of progress.

Coverage in the Boston Globe suggested that Trump’s decision to keep envoys in the U.S. was part of a broader approach. The paper described the move as an effort to maintain pressure on Iran, with officials indicating that the administration was prepared to wait for Tehran to initiate contact. The approach, while calculated, carried potential risks, as prolonged disruptions in the Strait of Hormuz could further strain global supply chains and corporate earnings.

Earnings Season vs. Geopolitics: Which Force Wins This Week?

Despite the focus on Iran, this week’s market activity was always expected to center on earnings. Five of the Magnificent Seven—Microsoft, Meta, Alphabet, Amazon, and Apple—are set to report, with their results likely to influence whether the market’s recent gains hold or reveal underlying vulnerabilities.

The early signals were mixed. Microsoft shares declined on Monday after the company announced it would end its exclusive partnership with OpenAI, a decision that raised questions among investors about its AI strategy. Alphabet, meanwhile, reached its first intraday record since February, demonstrating resilience among some of the market’s leading companies. Nvidia also approached all-time highs, while Amazon closed at a record level for the first time since November. The performance of these tech giants varied, but their collective impact would shape broader market sentiment.

The interplay between earnings and geopolitics defined the week’s market dynamics. Strong corporate results could help offset concerns about the Iran conflict, while disappointing reports might amplify the effects of rising oil prices. Gabriel Shahin of Falcon Wealth suggested that if earnings met expectations, markets could experience a period of relative calm. However, he noted that such stability might be short-lived, given the ongoing uncertainty in the Strait of Hormuz and the upcoming Federal Reserve meeting.

The bond market reflected these competing pressures. Treasury yields remained steady despite the rise in oil prices, indicating that investors were still assessing whether inflationary trends would influence the Fed’s decisions. The 10-year yield edged up to 4.32%, but the movement was subdued, suggesting caution rather than panic. That restraint could shift quickly if earnings disappointed or if tensions in the Strait of Hormuz escalated further.

What Investors Are Watching—and Ignoring

Traders on the NYSE floor focused on two key priorities this week: the performance of the Magnificent Seven and oil prices. Microsoft, Meta, Alphabet, Amazon, and Apple would collectively determine whether the market’s recent rally had lasting strength or if the latest gains were vulnerable to a pullback. Their results would also test whether the previous highs had become a new support level or if the market was poised for a correction.

Oil remained a critical factor. Brent crude’s 2% increase on Monday underscored the economic stakes of the Strait of Hormuz, through which roughly 30% of the world’s seaborne crude oil passes. The blockade’s impact was already visible in sectors like transportation and manufacturing, where higher fuel costs squeezed profit margins. If the strait remained closed, those pressures would likely intensify.

The Federal Reserve’s two-day meeting, which began Tuesday, drew less immediate attention. While no rate cut was expected, the Iran conflict had introduced new uncertainties into the inflation outlook. Jerome Powell’s final meeting as chair—before leadership transitions to Kevin Warsh—might have been a focal point under different circumstances. Instead, the market’s focus remained on earnings, oil, and the evolving situation in the Strait of Hormuz.

One potential catalyst for change was the Strait itself. If Iran’s reported proposal gained momentum or if the U.S. adjusted its stance, markets could react swiftly. For now, the status quo persisted—uncertain, unresolved, and costly. The S&P 500’s sideways movement was not merely a temporary pause but a reflection of the broader forces shaping the week’s market landscape.
