The mainland's largest foreign exchange bank, the Bank of China (BOC), has taken aggressive steps to cut its level of non-performing loans this year, including naming 30 delinquent borrowers. Xinhua reported that the BOC has asked eight of its branches, including the Guangdong branch, to give priority to collecting bad loans this year. Each month, the BOC will circulate details of the ten branches with the largest bad-loan balances and those whose bad-loan ratios increase the fastest. Job promotions at the branches will be closely related to their efforts in dealing with bad loans, Xinhua said, citing a BOC official. Despite a difficult economic environment, the BOC reduced its bad-loan ratio by 0.39 percentage points last year, Xinhua said, without giving a specific level. BOC is one of the four biggest state banks which are believed to hold non-performing loans totalling two trillion yuan (about HK$1.86 trillion), or about a quarter of their total loans. Separately, Zhang Hongyi, the deputy chief executive of the BOC's Hong Kong and Macau office, said the bank would support the restructuring of its well-run mainland corporate clients as they struggle under a credit crunch triggered by the collapse of Guangdong International Trust and Investment Corp last October. He said yesterday that mainland lending accounted for less than 20 per cent of the total loans of the 12 banks under the banner of his group.
