At about 3 pm on July 6, 2007, the international bank received a threatening phone call. The gangster claimed to have planted bombs in three branches of the bank and extorted 5 million yuan. As the branch where the bomb was planted was not specified on the phone, the police sent personnel to the Macao branch to conduct a thorough search and found nothing. The police suspect that this is a false report.
On September 23, 2008, there were rumors in Hong Kong, Macao and the Internet that Bank of East Asia, Macau International Bank and Macau Wing Hang Bank "had financial difficulties and held Lehman bonds, and Macau Monetary Authority was about to take over the bank". The Macao Association of Banks and its deputy general manager also held a press conference that afternoon to clarify the false rumors. However, after noon the next day, some branches (Chopsticks, Green Island and Sanjiaoyuan Sub-branches) had several times more depositors (100), forming a queue and forming a run, and Wing Hang Bank also had a run on the same day; By the next morning, people were still withdrawing their deposits (the Bank of East Asia in Hong Kong was also squeezed by similar rumors). Three days later, the bank announced the settlement: Macau International Bank was withdrawn about 300 million yuan from customers, and Wing Hang Bank was withdrawn about 550 million yuan, but the ratio of Hong Kong dollars to Macao dollars was not announced.
