The move came on the heels of a deal brokered by Swiss authorities to have UBS buy rival Swiss bank Credit Suisse to prevent its disorderly collapse and signals the depth of concern central bankers have over the recent turmoil in the financial system on both sides of the Atlantic.

"To improve the swap lines' effectiveness in providing U.S. dollar funding, the central banks currently offering U.S. dollar operations have agreed to increase the frequency of seven-day maturity operations from weekly to daily," the Fed said in a statement issued alongside announcements from the other five central banks.

Operations will commence on Monday and will continue at least through the end of April, the Fed said.
