After Israel attacked Iranian targets, the increasing violence caused oil prices to go up a lot and stock values to fall significantly on Friday. This happened because people were worried about possible problems with the world's oil supply and the economy. Big stock indexes like the S&P 500, Dow Jones Industrial Average, and Nasdaq composite all dropped a lot, while the price of U.S. crude oil went up by 7.3% to $72.98 per barrel. Even though experts often say that these sudden increases in oil prices usually go down once things calm down, Wall Street is watching the situation closely. As a result, companies that depend a lot on fuel and people feeling good about traveling, like the cruise company Carnival and United Airlines, lost a lot of money. On the other hand, U.S. oil companies, defense companies, and gold made money. Despite these changes in the market, inflation is still quite stable, but there are worries it could speed up because of President Trump's tariffs.
