Hanvit Bank, South KoreaÆs largest commercial lender, could be in big trouble again. Despite having raised some US$850 million this year, Hanvit is in no position to reduce its exposure to KoreaÆs top conglomerates by the governmentÆs time frame of 2002 and may need a new cash infusion if it wants to meet bad debt charges and tougher government lending rules.
