HSBC

HSBC, Hong Kong Shanghai Bank Corp, is the largest or second largest bank depending on how you stack them up. It used to prosper by the deposits from the rich Chinese (most were from Shanghai) to escape communists decades ago and the Chinese in SE Asia (unstable countries who are always angry with Chinese to control the local economies without thanking them to prosper their economies) for safe keeping. Before the takeover of HK, they moved the headquarter to London.
