Likening the U.S. credit crisis to a broken bathtub leaking water, financial services minister Yoshimi Watanabe is urging Washington to inject public money to fix the problem before it gets worse.

Sounding almost alarmist in an interview Wednesday, Yoshimi Watanabe used unusually blunt language to warn that drastic action was needed to address the crisis that has battered global markets.

"If there is a big hole in the bottom of the tub, no matter how much hot water you keep adding, you will never have enough hot water," Watanabe said.
