But this very good day capped off what was a very bad month for U.S. equities. The S&P 500 fell 5.09% in March, and the Nasdaq Composite declined 4.75%.

The U.S.-Israeli war on Iran and the near-total blockade of the Strait of Hormuz, a narrow, Iranian controlled waterway through which a fifth of the world’s crude oil typically transits every day, weighed heavily on markets throughout the month.

Tuesday was also the end of the first quarter of the year, one when the S&P 500 and Nasdaq posted their worst annual starts since 2022, when the Russian invasion of Ukraine rocked markets.

For the first quarter, the S&P 500 dropped 4.6% and the Nasdaq declined 7.1%.

Oil prices, meanwhile, soared over the past month, driving up the cost of fuel and triggering a domino effect of higher prices around the globe.

Brent, the international oil benchmark, posted its largest monthly percentage increase ever, after having risen more than 60%. The price of U.S. West Texas Intermediate crude oil also soared in March, climbing more than 50% in its biggest one-month gain since 2020.

For millions of drivers in the U.S., the increases manifest as higher prices for gas. And here, too, the past month was remarkable. The average price of unleaded gasoline hit $4 per gallon Tuesday, up more than 34% in just four weeks.

But it’s not just gas prices that hit U.S. households this month.

More than half of all adults in the U.S. own stocks, often via their retirement accounts and the broader funds those managed accounts invest in. Most of the time, market moves up and down don’t swing the value of those kinds of diversified retirement accounts.

But March was a different story.

“Stocks have been following the lead of oil prices at an unprecedented rate over the last several weeks, and if the U.S. just walked away from the Middle East with the Strait still blockaded, energy markets would likely remain incredibly supply-constrained, keeping prices high,” analysts at Bespoke Investment Group wrote Tuesday.

“The longer prices are high and supplies are limited, the worse it’s going to be for the global economy and ultimately stock prices,” they added.

The wild market swings of the second Trump administration are in sharp contrast to how Donald Trump said the markets would react if he were elected to a second term in 2024.

“There are many people that are saying that the only reason the Stock Market is high is because I am leading in all of the Polls, and if I don’t win, we will have a CRASH of similar proportions to 1929,” Trump wrote on Truth Social in May 2024 as he campaigned for the presidency.

Shortly after he was re-elected in 2024, Trump was asked whether he believed market indexes were good barometers of his performance in office. “To me … all of it together, it’s very important,” he told CNBC.

But during the first 14 months of his second term, U.S. markets have faced some of the sharpest drawdowns in history.

In February and March of last year, Trump’s sweeping tariff policies roiled the market, pushing the S&P 500 into its seventh-fastest correction of all time. A correction is when a stock or an index declines 10% from its most recent record high.

Just over a year later, the S&P 500 isn’t far from doing it again. As of Tuesday’s closing bell, the index had tumbled 6.7% from its most recent high in January.

As oil prices rise, stocks typically fall given that higher oil prices typically lead to higher prices across a number of industry sectors over the long run.

Already, inflation is on the rise around the world. On Tuesday morning, eurozone inflation came in at 2.5%, from 1.9% the month before, according to the European Central Bank.

On Tuesday, the Nikkei 225 in Japan recorded its worst month since 2008. In Europe, the Stoxx 600 index posted its worst month since 2022.

Two near-corrections in just over a year illustrates just how volatile the administration’s policies have been for markets.

Still, since Trump took office for a second time, the S&P 500 is up 8%, although last year global stocks far outpaced the broad U.S. index.

In 2025, global stocks as measured by the MSCI ACWI ex USA index rose nearly 30%, while U.S. stocks rose just 16%. Global stocks haven’t beaten American equities by that much during the first year of a presidential term since 1993, according to data from Bloomberg.

In recent weeks, Trump has repeatedly touted the Dow’s recent 50,000 milestone as a sign that the markets are doing well in his presidency.

“You know, it’s sort of crazy, I hit 50,000 on the Dow,” Trump said at an investment conference in Florida on Friday. “People said that wouldn’t be possible within four years.”

“And then we hit 7,000 on the S&P,” Trump added. “People said that’s even harder than hitting 50,000 on the Dow.”

As of Tuesday, the Dow had plunged more than 3,600 points since it hit 50,000, a drop of nearly 7.5%.
