Stock Market Today: S&P 500 Posts Best May in 30 Years Amid Hopes for Tariff Relief
May 30, 2025 – New York
The U.S. stock market closed out May with strong gains, marking the S&P 500’s best performance in the month of May since 1990. After a volatile trading session on Friday, investors pushed the index to a rise of more than 6% for the month, signaling renewed optimism on Wall Street fueled largely by potential progress on tariff negotiations between the United States and China.
Market Highlights
- S&P 500: Gained over 6% during May, its strongest May since 1990 and best monthly performance since November 2023. On Friday, it ended near the flat line, recovering from earlier losses.
- Dow Jones Industrial Average: Added approximately 4% over the month, edging up 0.1% on Friday.
- Nasdaq Composite: Posted a nearly 10% surge in May, led by strength in the technology sector, despite slipping 0.3% on Friday after recovering from a sharper intra-day loss.
Despite choppy trading throughout the day, the major indices all finished the week and month positively, buoyed by easing concerns over inflation coupled with hope for a reprieve in escalating U.S.-China trade tensions.
Trade Talks and Tariff Developments
Underlying much of the market’s tentative optimism is the anticipation of tariff relief between the world’s two largest economies. However, recent developments indicate that trade discussions remain fragile.
Bloomberg reported on Friday that the Trump administration is set to widen tech restrictions targeting China. New proposals aim to close loopholes by requiring U.S. government licenses for transactions involving subsidiaries of Chinese companies already on the Entity List, intensifying regulatory pressure on Chinese technology firms.
President Trump also renewed criticism of China on his social media platform, Truth Social, accusing Beijing of violating recent trade agreements shortly after the two countries announced a pause on some tariffs.
Scott Bessent, U.S. Treasury Secretary, remarked to Fox News that trade talks are currently "a bit stalled" and emphasized the need for direct dialogue between President Trump and Chinese President Xi Jinping to resolve issues related to semiconductor export controls and visa policies.
Legal Uncertainties Cloud Tariff Outlook
Adding to the market’s uncertainty are ongoing legal challenges to Trump’s global tariffs. A U.S. appeals court on Thursday granted a temporary halt to a lower court’s block on these tariffs, but the White House faces a Monday deadline to respond to the ruling. Meanwhile, the administration is exploring alternate means to maintain tariff enforcement.
Inflation Signals Stay the Course
Meanwhile, encouraging signs are emerging from the latest inflation data. April’s Personal Consumption Expenditures (PCE) index, particularly the core PCE preferred by the Federal Reserve, showed inflation rising at expected rates on both monthly and annual bases, suggesting inflation is cooling in line with expectations.
Investors welcomed these data points as supporting the Fed’s ongoing efforts to navigate inflation without disrupting economic growth.
Market Summary
Friday’s session saw stocks recover from early losses, closing the month on a positive note despite intermittent volatility. Technology stocks, a major driver of the Nasdaq’s performance, were particularly notable, though some individual companies like Nvidia saw share price dips amid the backdrop of trade tensions.
As Wall Street heads into June, market participants will closely monitor developments in U.S.-China trade relations, inflation trends, and corporate earnings to gauge the sustainability of this rally.
