HUF is the international currency code for the Hungarian forint, which is the national currency of Hungary. The forint was introduced on August 1, 1946, and was formerly divided into 100 fillér, but fillér coins are no longer in circulation. The currency remained relatively stable until the 1980s, but the transition to a market economy in the early 1990s adversely affected its value, and inflation peaked at 35% in 1991. The exchange rate of HUF to USD varies and is updated frequently.
