ABN Amro Bank NV may face another blow due to the troubles of Singapore-based oil trading giant Hin Leong, owned by billionaire Lim Oon Kuin, Het Financieele Dagblad reported April 17.

The bank is among the most exposed to the company having lent some $300 million to Hin Leong, which now has asked its creditors, a group of 23 banks, for a standstill agreement on loans of about $4 billion as it restructures its debt, the newspaper said. The news comes after ABN AMRO was forced to close €180 million in speculative positions of a U.S. client, the FD reported. The bank has declined to comment, it said.

U.K.-based HSBC Holdings PLC is the bank with the biggest exposure to Hin Leong, of $600 million, the Financial Times said in an April 16 report. French group Société Générale SA also has a sizable exposure of $240 million, the FT said. Other Singapore-based oil traders are worried Hin Leong's troubles may deter bank lending to the domestic sector, according to the FT.
