U.S. bank shares dropped on Tuesday after ratings agency Moody's downgraded credit ratings of several U.S. regional lenders and placed some banking giants on review for potential downgrade. It warned lenders will find it harder to make money as interest rates remain high, funding costs climb and a potential recession looms. The warning caught some investors off guard. On Tuesday, SPDR S&P Regional Banking ETF's (KRE.P) options-based 30-day implied volatility rose to 31.1%, up from 28.9% touched on Monday. "In the near term, there are reasons for caution about banks in general and we have made changes where appropriate," he said.
