Banks transferred funds out of the United States and into Europe in the first three months of 2008 as they turned to safer assets during the global credit crunch, the Bank for International Settlements said.

"In the first quarter of 2008, reporting banks continued their net transfer of funds out of the United States, a trend evident since the onset of the financial turmoil in mid-2007," the Swiss-based BIS said in its quarterly review of financial markets and banking activity, published on Monday.
