(Reuters) - JPMorgan Chase & Co (NYSE: JPM), Citigroup Inc (NYSE: C) and Wells Fargo & CO (NYSE: WFC) kicked off the second-quarter earning season with mixed reports.

While JPMorgan and Citi trumped analysts' profit estimates, scandal-hit Wells Fargo's results were clouded by expenses tied to past misconducts.

Overall, the U.S. banking sector is benefiting from a cut in corporate tax rates, hikes in interest rates and a growing economy that is driving demand from borrowers while holding down loan loss rates.

Bank of America Corp (NYSE: BAC), Goldman Sachs Group Inc (NYSE: GS) and Morgan Stanley (NYSE: MS) are scheduled to report results next week.
