The single currency tumbled to 1.2763 on a global slowdown together with the downgrade on Ireland’s long-term debt, prompting investors to buy U.S. dollar as safe-haven currency.

U.S. gross domestic product contracted at a 3.8% annual rate from October through December, the biggest decline since 1982. Moody's Investor Service's downgraded its outlook on Ireland's long-term debt. The Standard & Poor's rating agency earlier this month cut the credit ratings of Spain, Portugal and Greece.

The British pound rallied from 1.4185 to 1.4545 on better-than-expected mortgage data which showed that lenders in the U.K. granted 31,000 loans for house purchases in December, compared with 27,000 in previous month. The single currency fell sharply against the sterling from 0.9084 to 0.8804.

Swiss National Bank President Jean-Pierre Roth said he is ‘comfortable’ with the development of the franc and its moves have not been ‘brutal’. The Swiss franc declined briefly to 1.1660 per U.S. dollar after Finance Minister Hans-Rudolf Merz said that the government would support the central bank if it sold the currency to weaken it. SNB Vice Chairman Philipp Hildebrand said last week the bank stood ready to engage in unlimited currency intervention to weaken the franc and fend off deflation. Euro rebounded to 1.4996 against Swiss franc before falling again to close at 1.4860.
