"It's a huge threat to the leadership of an indispensable power," Klaus Scharioth, Germany's ambassador to Washington from 2006 until 2011, told The Associated Press. "That's bad news for all of us. It's bad news for Europeans because we're the closest partners of the U.S., but it's bad news for the rest of the world too if they don't exercise the power that they have."
He expressed the hope that American democracy can right itself in time to prevent another disaster once the current deal expires in January.
"The answer has to come from within," he said. "I hope the current situation is bad enough that people realize it cannot continue."
International Monetary Fund managing director Christine Lagarde said the shaky American economy needs more stable long-term solutions.
"It will be essential to reduce uncertainty surrounding the conduct of fiscal policy by raising the debt limit in a more durable manner," she said in a statement.
The stopgap nature of the solution that avoided a default left some experts warning that repeated dramas could sap confidence in the U.S., causing market problems with global implications.
Standard Chartered economist Samiran Chakraborty in Mumbai said American financial markets may over time lose faith.
"In three months' time, this could be back again," said Chakraborty. "If this kind of pushing it back happens several times, then this comfort that the markets had over the last 20 days that a deal will be reached, that comfort may now be dead."
Also, the congressional cliffhanger might dent longer-term confidence in American government debt, a cornerstone of global credit markets, prompting creditors to demand higher interest.
Xenia Dormandy, director of the Americas program at London's Chatham House, said the U.S. image had suffered a double blow, with both its economic and political credentials called into question
"There is a sense that the U.S. as a reliable ally is not necessarily the case anymore," she said, warning that both American allies and adversaries have reached this conclusion. But she, like others, said the damage is most likely short term.
Dormandy and other experts warned that the crisis isn't over and that it is too early to feel relief. Instead, those outside the U.S. must accept that confusion is an integral part of the American democratic system, she said.
Even if the current debate is resolved something else would likely come up and divide the country again, Dormandy added.
"If it's not the debt ceiling, it'd be something else," she said.
There are signs that the world is becoming weary of the repeated threats and counter threats that have become a regular feature of U.S. politics. The budget crisis has made many outside the U.S. question the way the world's leading power conducts its business at home even as it seeks to exert influence overseas.
