BNP Paribas, the biggest French bank, said Sunday that it has as much as €350 million, or $472 million, at risk from Madoff's investment advisory business. Nomura Holdings of Japan has ¥27.5 billion, or $302 million, at risk from Madoff's funds, while Banco Bilbao Vizcaya Argentaria of Spain may face up to €300 million in losses.
Madoff, 70, was arrested by federal prosecutors Thursday and charged with operating what he told his sons was a long-running Ponzi scheme in the New York-based firm's business advising rich people, hedge funds and institutions. He told senior employees that the firm was insolvent and "had been for years," prosecutors said in the criminal complaint.
"A frothy market encourages slack oversight," said Peter Hahn, a fellow of finance at London's Cass Business School. "Whenever something like this happens, everyone who has been hit will comb through their investments."
