New Taiwan dollar
The Taiwan dollar was replaced by the New Taiwan dollar on 15 June 1949, at the rate of 1 new dollar to 40,000 old dollars. The Nationalists were defeated by the Communists in December of the same year and retreated to Taiwan. The government then declared in the Temporary Provisions Effective During the Period of Communist Rebellion that dollars issued by the Bank of Taiwan would become the new currency in circulation.
