During the 1945-1946 Hungarian hyperinflation, when the rate of inflation reached quadrillion percent per month, the Hungarian government discovered that the real value of its tax receipts was falling dramatically. To keep real tax revenues more stable, it created a good called a "tax pengล," in which all bank deposits were denominated for purposes of taxation. Nevertheless, payments for goods and services were made only in terms of the regular Hungarian currency, whose value tended to fall rapidly even though the value of a tax pengรถ remained stable. Prices were also quoted only in terms of the regular currency. Lenders, however, began denominating loan payments in terms of tax pengรถs. In what ways did the tax pengรถ function as money in Hungary in 1945 and 1946?
