After Israel attacked Iranian targets, violence increased, causing oil prices to go up and stock prices to go down on Friday. This happened because people were worried about the global oil supply and the economy. Major stock markets like the S&P 500, Dow Jones, and Nasdaq all dropped a lot, while the price of U.S. oil went up by 7.3% to $72.98 per barrel. Experts often say that oil prices usually go down again if the situation doesn't get worse, but Wall Street is watching closely. Companies that use a lot of fuel or depend on people traveling, like Carnival cruises and United Airlines, lost a lot of money. However, U.S. oil companies, defense companies, and gold saw their values go up. Even with these changes, inflation is still quite stable, but some people are concerned that President Trump's tariffs could make it rise faster.
