RIKB stands for nominal Treasury bonds, RIKS stands for indexed Treasury bonds, and RIKV stands for Treasury bills. The figures indicate the maturity date (year, month, and day) of the bond series in question; for instance, RIKS 37 0115 is an indexed Treasury bond series maturing on 15 January 2037. Government Debt Management ensures liquidity and market creation for benchmark bonds through market making agreements in the secondary market. The agreements oblige market makers to maintain bid and ask quotes on the bonds in the Nasdaq Iceland and to renew them within a specified period of time. This means that buyers and sellers can always rely on the existence of a viable market for the main Treasury securities.
