Sp 500 jumps as war signals shift, but oil stays above $100 — the market’s uneasy contradiction
In one of the sharpest mood swings of this war-driven market, the sp 500 rose as investors latched onto signs President Donald Trump could be willing to end the war in Iran without a full reopening of the Strait of Hormuz—yet oil prices remained above $100 per barrel and U. S. gas prices crossed $4 per gallon nationally early Tuesday morning.
What moved markets: Sp 500 rises on Trump’s flexibility on Hormuz
U. S. stocks rallied Tuesday after Trump signaled he may wind down aggressive military action. The S&P 500 traded up about 1. 5% at one point, while the Dow Jones Industrial Average gained about 1. 1% and the tech-heavy Nasdaq Composite rose about 2. 1%.
The shift came after Trump told administration officials he would be willing to end the war in Iran without a full reopening of the Strait of Hormuz. His messaging, posted on his social media account Tuesday morning, appeared to counter earlier escalatory language. Trump wrote that Iran had been “essentially, decimated, ” adding: “The hard part is done. Go get your own oil!”
Markets have been reacting not just to battlefield developments but also to changing signals from Washington. Communications have been erratic: U. S. officials have pointed to potential progress in diplomatic discussions, while Trump has also floated the idea that the U. S. may move to seize control of Iran’s oil.
Oil’s warning signal: prices ease, then rise again, still above $100
The rally in equities ran into a stubborn reality in energy markets. Oil prices eased on Tuesday but still held above $100 per barrel as the U. S. -Israeli war against Iran entered its fifth week. West Texas Intermediate traded around $102 per barrel while Brent traded near $106.
Elsewhere in the morning’s trade, oil also rose despite the president’s comments, with U. S. benchmark West Texas Intermediate climbing above $103 per barrel and the international benchmark crossing $117. The conflicting moves underscored the dominant theme: even as investors respond to hints of de-escalation, markets remain highly sensitive to any signal that energy supply risks could persist.
On Monday, stocks showed that fragility. The S&P 500 slipped 0. 4% and left the index 9. 1% below its record set earlier this year. After an early gain of 0. 9%, the index erased nearly all of it before seesawing lower. The Dow added 49 points, while the Nasdaq composite fell 0. 7%.
That caution was tied directly to uncertainty about when the war could end and whether oil and natural gas could resume full flows from the Persian Gulf to customers worldwide fast enough to prevent a surge of inflation. Over the weekend, a “whirlwind of action” included Houthi rebels in Yemen entering the fighting—adding another layer of uncertainty for markets already struggling to price risk.
Household pressure points: gas above $4, diesel at $5. 45, and data ahead
While Wall Street traded on shifting headlines, consumers faced tangible costs. U. S. gas prices at the pump crossed over $4 per gallon nationally early Tuesday morning, based on AAA data. Diesel prices averaged $5. 45 per gallon. Those readings arrived as investors prepared for key U. S. economic releases due Tuesday, including the March consumer confidence reading and the February Job Openings and Labor Turnover Survey (JOLTS), both expected to shed light on the health of the U. S. economy.
Housing data added another piece to the picture. The S&P Cotality Case-Shiller 20-City Home Price Index showed home prices rose 1. 18% in January from a year earlier and 0. 16% from December, described as “meager gains” reflecting low-supply, low-demand dynamics. The reading came before fallout from the Iran war began pushing mortgage rates higher, a shift that has complicated affordability for first-time homebuyers and encouraged would-be sellers to stay put.
The tension across these indicators is now the defining contradiction for investors: the sp 500 can surge on any hint that hostilities may wind down, but energy prices and pump costs suggest the economic drag from the conflict may not fade quickly—even if rhetoric softens. For now, markets are left navigating between optimism sparked by shifting signals and the hard numbers still flashing pressure.
