North Korea
North Korea has the structural profile of a relatively industrialized country where nearly half of the Gross Domestic Product is generated by industry and human development is at medium levels. Purchasing power parity (PPP) GDP is estimated at $40 billion, with a very low per capita value of $1,800. In 2012, Gross national income per capita was $1,523, compared to $28,430 in South Korea. The North Korean won is the national currency, issued by the Central Bank of the Democratic People's Republic of Korea.
North Korean won
The won was revalued in November 2009 for the first time in 50 years. North Koreans were given seven days to exchange a maximum of ₩100,000 (worth approximately US$40 on the black market) in ₩1,000 notes for ₩10 notes, but after protests by some of the populace, the limit was raised to ₩150,000 in cash and ₩300,000 in bank savings. The official exchange rate at this time was around $740 but black market value of the ₩150,000 was estimated to be near $30. The revaluation, seen as a move against private market activity, wiped out many North Koreans' savings. "The Times" speculated that the move may have been an attempt by the North Korean government to control price inflation and destroy the fortunes of local black market money traders. The announcement was made to foreign embassies but not in North Korean state media. Information was later carried via a wire-based radio service only available within North Korea.
