On Tuesday, the S&P 500 index rose 1.17% to 6,966.78 points, nearing its record closing high of 6,978.60 set in late January. This surge was fueled by optimism surrounding potential peace talks between the United States and Iran, which also contributed to a decline in oil prices and the U.S. dollar. Brent crude futures fell by 4.6% to settle at $94.79 per barrel, while U.S. West Texas Intermediate crude dropped 7.87% to $91.20. The dollar index slid 0.24% to 98.10, reflecting market expectations for a symbolic deal that could ease tensions and reopen the vital Strait of Hormuz. Financial firms reported mixed earnings, with BlackRock's profit rising over 3%, while Citigroup also exceeded profit estimates. However, inflation data from the U.S. Labor Department showed a lower-than-expected rise in the Producer Price Index, adding to concerns about inflation's impact on monetary policy. Despite optimism in the stock market, rising energy prices are keeping inflation worries alive, prompting speculation about potential interest rate hikes by central banks.
