U.S. stocks surged on Tuesday, edging close to their all-time highs, as investor optimism grew following a reported ceasefire between Israel and Iran. The S&P 500 rose 1.1%, supported by gains across European and Asian markets. This rally brought the index within 0.8% of its February record after suffering a nearly 20% drop earlier in the year. The Dow Jones Industrial Average added 507 points (1.2%), while the Nasdaq composite climbed 1.4%, signaling broad market strength.
Falling Oil Prices Ease Inflation Fears, Boost Rate Cut Hopes and Market Confidence
The most notable market movement came from the oil sector, where U.S. crude prices dropped 6% to $64.37 a barrel, and Brent crude mirrored the fall. This sharp decline was driven by easing fears that the Israel-Iran conflict would disrupt global oil supplies. Despite previous concerns about potential blockades in the Strait of Hormuz, no attacks targeted oil infrastructure, reassuring investors. As a result, oil prices fell below pre-conflict levels, calming inflationary concerns.

Lower oil prices could help reduce inflation, potentially influencing the Federal Reserve’s monetary policy. With inflation easing, the Fed may be more inclined to cut interest rates, a move that markets typically welcome as it reduces borrowing costs and stimulates growth.
Although Fed Chair Jerome Powell emphasized caution and refrained from promising immediate action, he acknowledged that a rate cut is likely “sooner rather than later.” Treasury yields responded accordingly, with the 10-year and 2-year yields dipping to 4.29% and 3.81%, respectively.
Company Earnings and Global Optimism Drive Broad Stock Gains Across Major Markets
Several individual stocks made significant gains, further supporting the broader market’s rally. Carnival Corporation jumped 6.9% after reporting strong quarterly profits and high consumer spending on cruises. Uber rose 7.5% after expanding its autonomous vehicle offerings through a partnership with Waymo in Atlanta. Coinbase surged 12.1% as Bitcoin prices rallied above $105,000, showcasing continued investor interest in digital assets.
International stock markets also experienced robust gains as geopolitical tensions eased. Indexes in Europe and Asia climbed over 1%, with standout performances from Hong Kong (+2.1%) and South Korea (+3%). The ceasefire between Israel and Iran provided major relief to global investors, who feared escalating conflict could harm oil flows and economic stability. As a result, a wave of optimism swept across global markets, pushing them closer to record highs alongside Wall Street.
