Among these government bonds, KTBs are issued in the largest volume and trading is active. Accordingly, the on-the-run KTB market yields serve as a benchmark yield. These are currently six types of KTBs issued, according to maturity; 3-year, 5-year, 10-year, 20-year, 30-year, and 50-year KTBs. These KTBs fall into fixed-interest type bonds and inflation-linked KTBs (limited to the 10-year maturity, KTBis). KTBi links the principal and coupon rate of the KTB to a consumer price index.
