Dollar to dominate at least for a decade-IMF head

The dollar will still be the world's dominant currency in 10 years' time because the United States will still be the world's most important economy, the head of the IMF said on Monday.

However, Dominique Strauss-Kahn, the managing director of the International Monetary Fund, said he could not see 30 or 40 years into the future.

Answering questions put by university students, Strauss-Kahn said the outlook for the global economy remained fragile.
