S&P 將美國長期債信評等從 AAA 降級為 AA+，不知道這次金管會又會有何反應？要求銀行和保險公司提出因應方案？減持美債？如果評等為 AA+ 的美債要減持，那評等比美債還低，只有 AA- 的中華民國政府公債該不該減持？

US AAA credit rating downgraded

One of the top credit rating agencies, Standard & Poor's, has downgraded the United States' top-notch AAA rating.

S&P cut the long-term US credit rating by one notch to AA+ with a negative outllook, citing concerns about growing budget deficits.

S&P said it was because the deficit reduction plan passed by Congress on Tuesday did not go far enough.

Washington was locked in months of acrimonious partisan bickering over a bill to raise the US debt ceiling.

As rumours swirled earlier about the downgrade, unnamed US officials had told US media that S&P's analysis of the US economic situation was deeply flawed.

Correspondents say a downgrade could further erode global investors' confidence in the US economy, which is already struggling with huge debts and unemployment of 9.1%.

S&P said in its report issued late on Friday: "The 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 stabilise the government's medium-term debt dynamics.

"More broadly, the downgrade reflects our view that the effectiveness, stability, and predictability of American policymaking and political institutions have weakened at a time of ongoing fiscal and economic challenges."
