Fitch ratings agency has issued a strong warning to the United States to deal with its recurrent debt-ceiling dramas in a way which strengthens the economy in the long term, saying that its top "AAA" credit rating was at stake.
Fitch on Tuesday said it might revise downward its notation for the United States from the "AAA" level if Congress did not reach agreement on raising the ceiling for the national debt.
Fitch said that failure to raise the limit in time would lead to a formal revision by Fitch of its ratings of US debt instruments, but the agency also said the risk of a US default was extremely low.
However, Fitch also warned that fundamental strengths in the US economy were being undermined by the weight of debt and associated strains.
Fitch warned, that even if a crisis over the ceiling were averted in the immediate future, if the solution did not address the debt in a way which supported growth, then it was set to downgrade the US rating later in the year anyway.
Fitch Ratings said it expects that "Congress will raise the debt ceiling and that the risk of a US sovereign default remains extremely low.
"Nonetheless, and in line with our previous guidance, failure to raise the debt ceiling in a timely manner will prompt a formal review of the US sovereign ratings."
The legal ceiling for the US federal debt reached the limit of $US16.394 trillion ($A15.58 trillion) at the end of December. US politicians must agree on how to raise this limit within the next few weeks. Otherwise the United States will be unable to borrow to pay its bills.
The US found itself in a similar situation in August 2011. Deadlock within Congress caused one of the other top three rating agencies, Standard & Poor's, to downgrade its top-notch rating for US debt.
The Fitch statement said: "In Fitch's opinion, the debt ceiling is an ineffective and potentially dangerous mechanism for enforcing fiscal discipline.
"It does not prevent tax and spending decisions that will incur debt issuance in excess of the ceiling while the sanction of not raising the ceiling risks a sovereign default and renders such a threat incredible."
Fitch also said: "The extraordinary measures now being enacted since 31 December 2012, together with around $US43 billion Treasury deposits, are expected to allow the federal government to continue to fund itself until end-February."
"This estimate is provisional and sensitive to volatile monthly budget flows. It is highly uncertain what would happen if Congress did not raise the debt ceiling before the Treasury's borrowing authority and available cash balances were exhausted."Fitch, together with the third agency which still rates US debt at "AAA", Moody's, has already warned that this notation has a "negative" outlook, meaning that it is likely to be downgraded in the medium term.
