Text 2 South Korea banks in rate-rigging investigation

A South Korea financial regulator has started an investigation into alleged interest rate rigging by some of the country's banks. The Fair Trade Commission is looking at possible collusion over setting certificates of deposit (CD), used as a benchmark to set lending rates. It follows the Libor-rigging scandal involving Barclays and possibly several other UK banks.

A CD is a way of saving with a fixed interest rate and maturity sold by banks and circulated in the secondary market by brokerages. Financial firms benefit from a high CD rates as many household loans are linked to them. They are frequently used to help South Koreans buy homes. The possible rigging of CD can help flatter companies' financial health.

The indebtedness of South Koreans has become a particular worry to the authorities as the economy slows.
