KEY POINTS

  • Moody’s had been a holdout in keeping U.S. sovereign debt at the highest credit rating possible, and brings the 116-year-old agency into line with its rivals.
  • The decision to lower the United States credit profile would be expected, at the margin, to lift the yield that investors demand in order to buy U.S. Treasury debt to reflect more risk, and could dampen sentiment toward owning U.S. assets, including stocks.
