Economy of North Korea
Estimating gross national product in North Korea is a difficult task because of a dearth of economic data and the problem of choosing an appropriate rate of exchange for the North Korean won, the nonconvertible North Korean currency. The South Korean government's estimate placed North Korea's GNP in 1991 at US$22.9 billion, or US$1,038 per capita. In contrast, South Korea posted US$237.9 billion of GNP and a per capita income of US$5,569 in 1991. North Korea's GNP in 1991 showed a 5.2% decline from 1989, and preliminary indications were that the decline would continue. South Korea's GNP, by contrast, expanded by 9.3% and 8.4%, respectively, in 1990 and 1991.
South Korean won
The Bank of Korea is the only institution in South Korea with the right to print banknotes and mint coins. The banknotes and coins are printed at KOMSCO, a government-owned corporation, under the guidance of the Bank of Korea.
After the new banknotes and coins are printed/minted, they are bundled or rolled and shipped to the headquarters of the Bank of Korea. When delivered, they are deposited inside the bank's vault, ready to be distributed to commercial banks when requested.
Every year, around Seollal and Chuseok, two major Korean holidays, the Bank of Korea distributes large amounts of its currency to most of the commercial banks in South Korea, which are then given to their customers upon request.
