Standers & Poor's reduced the US's long-term on August 15 to become at AA+ after the credit rating of the United States remains at AAA.

This comes after Moody's Investors Service and Fitch Ratings affirmed their AAA credit ratings for the U.S. on Aug. 2, the day President Barack Obama signed a bill that ended the debt-ceiling impasse which had pushed the Treasury to the edge of default.

As for the Standard & Poor's, which said this downgrade reflects our opinion that the fiscal consolidation plan that Congress and the Administration recently agreed to falls short of what, in our view, would be necessary to stabilize the government's medium-term debt dynamics.
