US Stocks Gain 12% Since March Low as Investors Look Past Iran War

The S&P 500 has rallied over 12% since its March 30 low, hitting fresh all-time highs as investors weigh signs of a potential ceasefire in the Middle East against persistent inflation and energy risks. The benchmark index, along with the tech-heavy Nasdaq Composite, has erased the sharp losses seen at the outset of the U.S.-Iran conflict, demonstrating a surprising resilience that has many on Wall Street recalibrating their outlooks for the second quarter.

"If oil continues to retreat and the conflict truly does de-escalate, equities have room to recover because the first quarter already reflected a meaningful repricing of geopolitical and inflation risk," David Miller, Sr. Portfolio Manager at Catalyst Funds, said in written commentary. "However, if energy remains elevated, Q2 becomes much more challenging because higher fuel costs start to pressure margins, consumer spending, and the Fed’s flexibility all at once."

The market's recovery follows a volatile period that saw the S&P 500 drop roughly 8% between the start of U.S. airstrikes on February 28 and March 30. The rebound has been fueled by investor optimism that a peace deal could be reached. That sentiment was tested Tuesday, as stocks fell 0.6% and oil prices jumped after a report that peace talks were "put on hold." West Texas Intermediate futures rose 2.4% to $91.80 a barrel, while the 10-year Treasury yield climbed to 4.31%.

The rally forces investors to question whether markets have become too complacent about the war's economic impact. While a less energy-intensive global economy provides a buffer against oil shocks, sustained high prices could still pressure corporate margins and consumer spending, testing the market's bullish conviction as the conflict continues.

A More Resilient Economy

One key reason for the market's ability to absorb the energy shock may be the global economy's changing structure. According to research from Standard Chartered, the world's "energy intensity" — the amount of energy required to generate a unit of economic growth — has fallen by 58% since the 1970s. This increased efficiency means that while the recent spike in oil prices to nearly $100 a barrel is painful, it is not the same crippling blow it might have been in previous decades.

This structural shift has allowed investors to look past the immediate disruptions, such as the blockade of the Strait of Hormuz, and focus on a potential post-war recovery. JPMorgan recently raised its year-end price target on the S&P 500 to 7,600, with a "blue sky" scenario of 8,000 if geopolitical tensions are resolved quickly.

Risks Remain on the Table

Despite the optimism, analysts caution that significant risks persist. The U.S. naval blockade on Iranian ports remains in force, and the path to a lasting peace is uncertain. "Significant risks remain on the table," said Charlie Ripley, senior investment strategist at Allianz Investment Management, noting that a diplomatic shift has only reduced fears of a prolonged escalation.

The economic fallout is already visible. March retail sales in the U.S. surged 1.7%, but the increase was driven by a record 15.5% jump in sales at gas stations, reflecting higher prices at the pump. In Europe, the conflict has had a more direct impact, with German investor morale sinking to a three-year low in April, according to the ZEW economic research institute.

For investors, the recent market action serves as a lesson in patience. After the initial sell-off, those who held their positions were rewarded as the market recovered. It’s a dynamic that echoes the advice of Vanguard founder Jack Bogle: "Don't do something — just stand there." While the war's ultimate impact on the global economy is still unfolding, the stock market has, for now, voted for optimism.
