LONDON, Sept 12, 2007 (AFP) - The European single currency shot to an all-time high of 1.3879 dollars Wednesday on fears of a recession in the United States and the prospect of lower interest rates in the world's biggest economy.

The US Federal Reserve is next week expected to cut American borrowing costs from 5.25 percent, where they have stood for more than a year amid weak US economic data and a global credit squeeze caused by the American housing downturn.

A total of 13 countries have adopted the euro since its birth on January 1, 1999.
