Walmart, the world's largest retailer, will have to start raising prices later this month due to the high cost of tariffs, executives said on Thursday, in a clear signal that U.S. President Donald Trump's trade war is filtering through to the American economy.

Walmart on Thursday said even the discounter will have to raise prices on some items because of tariffs. Bananas, roses, avocados and toys are some the items hit by higher tariffs, according to the company.

During an earnings call Thursday Walmart said it will be forced to raise prices soon even with the reduced tariffs on China as trade with the United States is negotiated.
