Types of government debt securities are listed below:

Malaysian Government Securities (MGS) - coupon bearing long-term bonds issued by the Government of Malaysia to raise funds from the domestic capital market. They are the most actively traded bonds.

Malaysian Treasury Bills (MTB) - short-term securities issued by the Federal Treasury of Malaysia for working capital.

Government Investment Issues (GII) - non-interest bearing government securities based on Islamic principles, issued by the Government of Malaysia and placed on a competitive tender with maturities of one year or more. Funds are used for development expenditures.

Bank Negara Monetary Notes (BNMN) – discounted or coupon-bearing government securities with maturity of one to three years. BNMN are issued by the central bank to manage liquidity in both the conventional and Islamic market, gradually replacing Bank Negara Bills and Bank Negara Negotiable Notes beginning December 2006. BNMN are offered through competitive auction through principal dealers.

Merdeka Savings Bonds (BSM) are targeted at retirees by offering a slightly higher return than the market rate and a tax exemption. A unique feature of the BSM is that they are all based on the Islamic banking concept of Bai' Al-Inah (sell-and-buy-back arrangement).
