The recent rise in violence after Israel attacked Iranian sites led to a big increase 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 the 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. crude 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 once things calm down, Wall Street is watching the situation closely. As a result, 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 saw their value go up. Despite these market changes, inflation is still quite steady, but there are worries it could speed up because of President Trump's tariffs.
