After Israel attacked Iranian targets, the increasing violence caused oil prices to go up and stock markets to go down on Friday. This happened because people were worried about possible problems with the world's oil supply and economy. Big stock indexes like the S&P 500, Dow Jones Industrial Average, and Nasdaq composite all fell a lot, while the price of U.S. crude oil went up by 7.3% to $72.98 per barrel. Even though experts say that these oil price increases often go down when the situation becomes clearer, Wall Street is watching closely. Because of this, companies that rely on fuel and people feeling good about travel, 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 steady, but there are worries it could speed up because of President Trump's tariffs.
