After Israel attacked Iranian targets, the increased violence caused worries about the world's oil supply and economy, leading to higher oil prices and a drop in stock markets on Friday. Important stock indexes like the S&P 500, Dow Jones Industrial Average, and Nasdaq composite all fell a lot, while the price of U.S. oil went up by 7.3% to $72.98 per barrel. Even though experts say that these sudden rises in oil prices often go down when the situation calms, Wall Street is watching closely. Because of this, companies that rely on fuel and people feeling good about travel, like 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, though some worry it could speed up because of President Trump's tariffs.
