Since 1983, Hong Kong has established a linked exchange rate system linking the issuance of Hong Kong dollars to the US dollar. You can't print money until you get the debt certificate. In this way, the US dollars held by the Exchange Fund provide support for the stability of Hong Kong dollar banknotes.
The first paper money in Hong Kong was issued by Credit Suisse Oriental on 1845, but it didn't really circulate universally for a long time. Until 1857, the Hong Kong government allowed payment by paper money, and many banks began to issue paper money one after another. By 1865, the banknotes issued by five banks have been recognized by the Hong Kong government, but the banknotes below 5 yuan cannot be issued unless specially licensed. The actual monetary unit of Hong Kong dollar is1935165438+10 month.
