After Israel attacked Iranian targets, the increased violence led to a quick rise in oil prices and a fall in stock markets on Friday. This happened because people were worried about possible problems with the world's oil supply and economy. Important stock indexes like the S&P 500, Dow Jones Industrial Average, and Nasdaq composite all went down a lot, while the price of U.S. oil went up by 7.3% to $72.98 per barrel. Even though experts say that oil prices often go down again when 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 travel, such as 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 some people are concerned it could speed up because of President Trump's tariffs.
