Etymology of the Korean currencies
The won is the currency of both North and South Korea. "Won" is a cognate of the Chinese currency unit, the yuan (//), and the Japanese currency unit, the yen (; ¥), meaning "round object". The won is subdivided into 100 jeon ().

In 2009, another currency reform was initiated to tackle hyperinflation and black market activities. Unlike previous reforms, the 2009 move sparked a nationwide panic when it was announced there would be a two-week waiting period between the withdrawal of the old currency and the introduction of the new currency, coupled with an exchange limit of only 500,000 old won for each person, effectively wiping out savings. The state eventually pulled back on most exchange limits; however, the revaluation proved to be a failure.
