What are the types of SGS?

SGS are issued in a variety of maturities, ranging from as short as 1 month to as long as 30 years. They are denominated in Singapore dollars and are issued through a competitive bidding process that is open to banks, financial institutions, and individuals.

These debt instruments take two forms

  • Treasury bills (T-bills) or
  • Singapore Government Securities (SGS) Bonds

The terms of issuance are governed by the Local Treasury Bills Act and the Government Securities Act respectively.


T-bills are short-term debt securities that mature in one year or less from their issue date. They are bought and sold at a discount, i.e. at a price less than their face (par) value.

When they mature, the Government will pay the holder an amount of S$ equivalent to the face value of the security. Therefore, the interest earned on the T-bill is the difference between its purchase price and face (par) value.

They are denominated at nominal values of S$1,000 and traded at a rate of discount basis. The Singapore Government typically issues T-bills with 6-month and 1-year maturities.

SGS bonds

SGS bonds are longer-term debt securities ranging from 2 to 50 years, It pays a fixed rate of interest (called the coupon) every six months for the life of the securities and then their face (par) values upon redemption on maturity.

They are generally not issued at a discount unlike T-bills and have typical maturities of 2, 5, 10, 15 and 20 years.

The most recently issued SGS bonds in each of these tenors, being the benchmark securities, are more actively traded. Older and more seasoned SGS bonds become off-the-run issues and are less actively traded. SGS bonds are also denominated in nominal values of S$1,000 and traded on a price basis expressed in terms of S$100 principal.
