(Reuters) - The U.S. banking industry is enjoying the benefits of a growing economy and lower taxes, if the double-digit profit growth posted by three major lenders on Friday is any indication.

JPMorgan Chase & Co, the biggest U.S. bank, said its third-quarter profit jumped nearly 25 percent, with each of its four business units generating higher revenues.

Citigroup Inc, the No. 3 U.S. bank by assets, reported a 12 percent rise in profit, driven mostly by lower taxes and cost savings.

Wells Fargo & Co, the fourth-largest in the sector, reported a 32 percent surge in profit following strong demand for auto, small business and personal loans, as well as cost cutting.
