"We believe it is important for G20 nations to commit to substantial and sustained actions for a period that matches the likely duration of the crisis," Geithner told reporters ahead of a weekend meeting in southeast Britain of finance ministers from the G20 rich and developing nations.
He said it was also vital to take decisive actions to strengthen the financial regulatory system and pledged to lay out more details of U.S. actions before another G20 gathering in April where political leaders will try to agree on how to bring a global recession to an end.
"There has been a lot of talk of reform. Now is the time for action," Geithner said, adding that the G20 must work together to restore global growth.
"We must at the same time build a strong supervisory and financial regulatory framework for the future to ensure no such crisis occurs again," he added.
