On Tuesday, U.S. stocks experienced a substantial rally, with the S&P 500 climbing 2.9%, the Nasdaq gaining 3.8%, and the Dow surging by 1,125 points. Despite this encouraging uptick, the day concluded a notably poor month for the markets, marked by a 5.09% decline in the S&P 500 and a 4.75% drop in the Nasdaq Composite throughout March.
The backdrop for this volatility was a combination of geopolitical tensions and economic pressures. Ongoing conflict between the U.S. and Israel against Iran, along with a near-total blockade of the Straits of Hormuz—an essential waterway for global oil transport—heavily influenced market dynamics. The end of the first quarter of the year also revealed disheartening statistics, as both the S&P 500 and Nasdaq recorded their worst beginnings to a year since the turbulent start of 2022, following the Russian invasion of Ukraine. For the entirety of the first quarter, the S&P 500 fell by 4.6% and the Nasdaq dropped 7.1%.
Compounding these issues, oil prices surged dramatically last month, leading to increased fuel costs that ripple throughout the global economy. The benchmark Brent crude saw its largest monthly percentage gain ever, exceeding a 60% increase, while U.S. West Texas Intermediate crude climbed over 50%, marking its steepest one-month rise since 2020. As a result, the average price of unleaded gasoline spiked to $4 per gallon on Tuesday, reflecting a staggering 34% increase in just four weeks.
This month’s market turbulence particularly impacted U.S. households, given that over half of American adults own stocks, predominantly through retirement accounts. While the effects of typical market fluctuations usually don’t significantly alter the value of diversified retirement funds, March proved to be an exception. Analysts from Bespoke Investment Group noted a previously unseen correlation between stock prices and rising oil costs, warning that prolonged high prices and constrained supply would increasingly threaten global economic stability and ultimately adversely affect stock valuations.
These fluctuations in the market are particularly striking given the contrasting expectations set by President Donald Trump during his re-election campaign. He suggested that his leadership was integral to maintaining high stock market values, asserting on Truth Social that failure to win would result in a dramatic market crash akin to the 1929 crisis. Despite claiming that market indexes were crucial indicators of his performance, Trump’s administration has faced severe market declines, including significant corrections due to tariff policies.
As of Tuesday, the S&P 500 stood 6.7% lower than its peak in January, echoing concerns about potential economic instability. Higher oil prices have historically led to market downturns, contributing to rising inflation globally. Recent reports indicated the eurozone inflation rate increased to 2.5% from 1.9%. Japan’s Nikkei 225 recorded its worst monthly performance since 2008, while European markets like the Stoxx 600 also reflected significant decline, marking their worst month since 2022.
Amidst these challenges, the volatility in the markets under Trump’s second administration illustrates the unpredictability of current policies. While the S&P 500 has managed to climb 8% since he took office for a second term, global stock indices have outperformed U.S. equities, highlighting a shifting international landscape. In 2025, global stocks increased nearly 30%, while U.S. stocks only grew by 16%, showcasing a rare discrepancy not seen in the early year of a presidency since 1993.
In recent weeks, Trump has pointed to the Dow reaching the 50,000 milestone as a sign of successful market management, though as of Tuesday, the index has dropped over 3,600 points since hitting that peak, representing a nearly 7.5% decline. This volatility underscores the continuing challenges facing both the administration and the broader economy as it grapples with rising energy costs and geopolitical instability.
