For example, the Hong Kong dollar implements an issuance system linked to major international currencies. Before 1972, Hong Kong was a member of the British pound zone and the Hong Kong dollar was linked to the pound sterling. Therefore, note-issuing banks must deposit pound sterling or qualified collateral to the Monetary Authority in accordance with the prescribed ratio before issuing notes, and in exchange for interest-free certificates of indebtedness. On October 17, 1983, Hong Kong implemented a linked exchange rate linked to the U.S. dollar. When issuing Hong Kong dollars, note-issuing banks must deposit 100% of the U.S. dollar reserve at the exchange rate of 1 U.S. dollar to 8 Hong Kong dollars, and exchange it for the HKMA issued under the Exchange Fund account. Only the interest-free certificate of debt can be issued with equivalent Hong Kong banknotes. The Hong Kong Monetary Authority now manages the monetary policy in a unified manner, but it authorizes HSBC, Standard Chartered and banks to act as note-issuing banks.

But this possibility is extremely small.
