Moody's cuts senior debt of major banks.

Moody's has lowered the senior debt ratings of Morgan Stanley (MS), Goldman Sachs (GS), JPMorgan (JPM) and BNY Mellon (BK) by one notch, based on its updated views on U.S. government support and standalone bank considerations. The credit ratings of these banks had each benefited from the assumption of government support, Moody's said, and its rating actions reflect strengthened U.S. bank resolution tools that affect its assumptions about such support.
