After Israel attacked Iran, there was more fighting. This made oil prices go up a lot and stock prices go down on Friday. People were worried about the world's oil and money. Big stock markets like the S&P 500 and Dow Jones lost a lot of value. The price of oil went up to $72.98 for one barrel. Experts think oil prices might go down if the situation doesn't get worse. But Wall Street is still watching closely. Companies that use a lot of fuel, like Carnival cruises and United Airlines, lost money. But oil companies in the U.S., companies that make weapons, and gold made money. Prices for things are still mostly the same, but people are worried they might go up because of new taxes from President Trump.
