There were no HK bank failures between 1935 and 1964 and in 1965 they used a government-backed takeover, which has been SOP for the Bank of England for a long time.

Hong Kong hasn't had a bank failure since the Hong Kong Monetary Authority was founded in 1993, though it has a long history of financial crises associated with its lenders. There was a brief run on Standard Chartered Plc and Citigroup Inc.'s local unit after the failure of BCCI Group in 1991, while the failure of a small Hong Kong bank in the 1980s triggered runs on rivals and led to efforts to strengthen regulation.

A banking crisis in 1965 prompted a government-backed takeover of Hang Seng Bank Ltd. by the Hongkong and Shanghai Banking Corp. for HK$51 million ($6.6 million). HSBC Holdings Plc now owns 62 percent of Hang Seng, which has a market value of $36.5 billion.
