Stock prices in the U.S. went up a little on Wednesday. This happened because the main bank did not change interest rates, as many people thought. But the bank also said the U.S. economy might have more problems.

The stock market went up today.

Stock markets changed a lot during the day. One important market went up 400 points for a short time. This happened because people hoped the US and China might start to agree on trade. This agreement could help the world economy. The two biggest economies have been putting more taxes on goods from each other. This is like a trade war. People are afraid this war could cause money problems unless they trade more easily.

Talks between the US and China this weekend made people more hopeful. But this hope went down after President Trump said he would not lower the taxes on Chinese products. China wants these taxes to be lower before they start talking about trade.

Sometimes, not knowing about taxes on goods makes the U.S. economy change quickly. For example, people bought many things from other countries to avoid paying more taxes later. Even though people are worried about the future, the central bank said the economy is still doing well now.

Jerome Powell, the head of the US central bank, said they can wait before changing interest rates. This is true even though Trump wants them to lower rates faster to help the economy.

Powell said, "We don't know much." So, like others in the financial world, the Fed is waiting to see what happens with Trump's trade plan and if his taxes on goods, which were stronger than people thought, will work as he said.

This is especially true now because the trade war seems to be changing, Powell said.

The Fed also said it knows that tariffs are making the economy face more risks. 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 slower, and more people might lose their jobs.

This could cause a bad situation for the economy. This happens when the economy is not growing, but prices are still high. It is a problem because the government does not have easy ways to solve it. If they try to help businesses and jobs, prices might go up more. If they try to stop prices from rising, it could hurt businesses and jobs.

Meanwhile, big American companies are making more money at the start of 2025 than experts thought.

The Walt Disney company's stock went up a lot, 10.8%. This happened because they earned more money than expected. They also said they think they will earn even more money in the future and got over a million new people to sign up for their online service.

But companies are also still saying that it's hard for them to know what will happen with their money because the economy is not certain.

The company Marvell Technology, which makes computer chips, saw its stock price go down by 8%. They changed the date of their meeting for investors from June to a time they don't know yet because they are not sure about the economy.

The S&P 500 index went up by 24.37 points and is now at 5,631.28. The Dow Jones index also went up by 284.97 points and is now at 41,113.97. The Nasdaq index went up by 48.50 and is now at 17,738.16.

In the bond market, interest rates went down after the central bank said something. The rate for the 10-year government bond went down a little from 4.30% to 4.27%.

Markets in Europe usually went down, but markets in Asia went up.
