The basis was the Act of 11 January 1924 on the Rehabilitation of the State Treasury and Currency Reform, which entered into force on 15 January. The Sejm gave the government special powers for six months: to change taxes, introduce a new currency system, grant a charter to the issuing bank and borrow up to 500 million gold francs. The Presidential Regulation of 20 January 1924 on the Monetary System stated that the Republic’s monetary unit was the złoty, equal to the Swiss franc and corresponding to 9/31 of a gram of pure gold.
Printing marks to cover the treasury deficit ceased on 1 February 1924. The Regulation of 14 April 1924 on Changing the Monetary System set the exchange rate at 1,800,000 Polish marks to one złoty. On 28 April 1924, Bank Polski SA began operating in Warsaw with the exclusive right to issue banknotes, and from 1 July 1924 the mark ceased to be legal tender. The reform was funded mainly from the state’s own resources, including sales of Bank Polski shares.
Stability did not last forever. The economic situation began deteriorating from July 1924, with a poor harvest and the 1925 tariff war with Germany contributing. In July 1925, the złoty’s exchange rate faltered; on 12 November Bank Polski refused to release further foreign currency to support it, and Grabski resigned the next day. The złoty finally stabilised in 1927, but the name given to it in 1924 remains today.
