After Israel attacked Iran, there was more fighting. This made oil prices go up and stock prices go down on Friday. People were worried about the world's oil and economy. Big stock indexes like the S&P 500, Dow Jones, and Nasdaq all dropped a lot. The price of oil went up by 7.3% to $72.98 for one barrel. Experts think oil prices might go down if the situation does not get worse. But Wall Street is watching closely. Companies that need a lot of fuel or depend on people traveling, like Carnival and United Airlines, lost money. But oil companies in the U.S., defense companies, and gold made money. Even with these changes, prices are still mostly stable. But some people are worried that President Trump's tariffs could make prices go up faster.
