Stock prices in the U.S. went up a little on Wednesday. This happened after the main bank of the U.S., the Federal Reserve, decided not to change interest rates. Many people thought this would happen. But the bank also said that there are more and more dangers for the U.S. economy.

The S&P 500 went up a little after falling for two days. The Dow Jones Industrial Average also went up a lot, and the Nasdaq composite went up a little.

Stock prices changed a lot during the day. The Dow Jones index went up 400 points for a short time. This happened because people hoped the US and China would start talking about a trade deal. This deal could help the world economy. The US and China are the two biggest economies. They have been putting more taxes on goods from each other. This is like a trade war. People are worried this could cause money problems if they don't trade more easily.

News about a meeting between the U.S. and China this weekend made people hopeful. But then President Trump said he would not lower taxes on goods from China before talking. This made some people less hopeful. China says the U.S. must lower these taxes before they can have trade talks. This weekend's meeting is planned to help start these talks.

The economy changes a lot because people are not sure about taxes on things from other countries. For example, companies bought many things from other countries quickly to avoid these taxes. Even though people feel less positive about the future, the government says the economy is still doing well now.

Jerome Powell, who leads the central bank, said they can wait before changing interest rates. This is true even though Trump wants them to lower rates sooner to help the economy.

"We don't know a lot," Powell said. So, like other people, the Fed is waiting to see what happens with Trump's trade war and if his taxes on goods, which were bigger than people thought, will work as he planned.

Powell said this is true because the trade war seems to be changing and the US is talking more about trade with other countries.

Also, the US central bank said it knows that tariffs are making the economy riskier. This could mean fewer jobs and higher prices.

Powell said that if taxes on imported goods stay high, prices will probably go up, the economy will grow more slowly, and more people might lose their jobs.

This could lead to a bad situation called "stagflation." This means the economy is not growing, but prices are still high. It is difficult to fix this because the central bank does not have good ways to solve it. For example, if they lower interest rates to help businesses and jobs, prices might go up more. If they raise rates, the opposite would happen.

Big American companies are making more money at the start of 2025 than people thought.

The Walt Disney company's stock price went up a lot, by 10.8%. This happened because they made more money than experts thought. They also said they think they will make even more money later, and they got over a million new people who watch their online shows.

But companies are also saying that the uncertain economy makes it harder for them to know how much money they will have.

The company Marvell Technology makes computer chips. Its shares went down 8% because it changed the date of its meeting for investors. It moved the meeting from June to a later time because they are not sure about the economy.

The S&P 500 went up by 24.37 points to 5,631.28. The Dow Jones Industrial Average also went up by 284.97 points to 41,113.97. The Nasdaq composite went up by 48.50 to 17,738.16.

After the government shared some news, the interest rates on their bonds went down. The rate on the 10-year bond went from 4.30% to 4.27%.

In Europe, most markets went down, but markets in Asia went up.
