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 that the world might not get enough oil and that the economy could have problems. 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 that oil prices often go down again if the situation doesn't get worse. But people who work in finance are still watching closely. Companies that need a lot of fuel, like Carnival (a cruise company) and United Airlines, lost money. But oil companies in the U.S., companies that make weapons, and gold became more valuable. Even with these changes, prices of things in general are not rising very fast. However, some people are concerned that President Trump's new taxes could make prices go up faster later.
