As US president Barack Obama warned: "We've got to get out of the habit of governing by crisis," the IMF's managing director, Christine Lagarde, appealed for more stability.
"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.
"We also continue to encourage the US to approve a budget for 2014 and replace the sequester with gradually phased-in measures that would not harm the recovery, and to adopt a balanced and comprehensive medium-term fiscal plan."
A Senate-drafted peace deal that contained almost no concessions to the conservatives who had driven the country to the precipice of a new financial crisis was passed by the Republican-dominated House of Representatives just hours before a deadline to extend the US debt limit was to pass.
The World Bank too expressed its relief that the global economy had "dodged a potential catastrophe", with its president, Jim Yong Kim, urging policymakers in all countries to "continue to focus on crafting and implementing policies that promote economic growth and boost jobs and opportunity for all".
