The S&P 500 jumped 1.65% to 7,554.29 on Monday after President Trump announced a tentative deal with Iran to end their conflict and reopen the Strait of Hormuz. Oil prices fell 4.9% to $80.75 per barrel on the news. Investors now watch June 16 for inflation data that could determine whether the Federal Reserve raises interest rates later this year.
Oil Prices Collapse on Peace Agreement
U.S. crude fell to $80.75 per barrel, down 4.9% on Monday, after Trump authorized the reopening of the Strait of Hormuz. Brent crude dropped 4.8% to $83.17. The deal removes a major supply risk that had pushed oil above $100 per barrel just weeks earlier. Vice President JD Vance told CNBC the strait will open toll-free for the long term, though full energy industry recovery may take months.
Tech Stocks Lead the Rally
The Nasdaq Composite surged 3.07% to 26,683.94, its best day since March 31. Nvidia climbed 3.5%, providing the strongest push to the S&P 500. SpaceX extended its rally with a 20% jump after its public debut on Friday. The Dow Jones Industrial Average added 468.77 points, or 0.92%, to close at a record 51,671.03.
Inflation Data Could Shift Market Direction
June 16 marks a key date for markets as traders await inflation data that may signal Fed policy. The recent inflation uptick was tied to rising gasoline prices, but 3- and 5-year inflation expectations have declined to 2.40%, suggesting markets do not expect runaway inflation. Lower oil prices should ease consumer pressure and reduce the case for rate hikes.
S&P 500 Gains 78% Over Three Years
The S&P 500 has climbed 78% over the past three calendar years, driven by investor optimism about artificial intelligence. The index posted 41 new 52-week highs and only 3 new lows on Monday. However, the path has not been smooth, with first-quarter declines and recent volatility tied to geopolitical risks and rate hike concerns.
Final Thoughts
The S&P 500’s 1.65% rally reflects relief over lower oil prices and reduced geopolitical risk. With inflation expectations stable and the Fed unlikely to raise rates soon, the data supports continued upside for equities in the near term.
