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.
Korean currency
From 1978 to 2001, the North Korean government maintained an iconic rate of 2.16 won to the US dollar; since then banks in the country exchange at rates closer to the black market rate. However, rampant inflation has been eroding the North Korean wŏn's value to such an extent that currently it is believed to be worth about the same as the South Korean wŏn (needs sourcing). In any case, the U.S. dollar and other currencies are still worth more in North Korean wŏn on the black market than officially.
