Malaysian Government Securities (MGS) are conventional fixed-rate bonds issued by the Government of Malaysia, and the Government Investment Issue (GII, shown as MGII on BNM's investor portal) is their Shariah-compliant counterpart. Both are sold by Bank Negara Malaysia (BNM) on the Government's behalf through competitive auctions, are direct obligations of the Government, and trade over the counter.

MGS are long-term bonds the Government issues to finance development expenditure. They pay a fixed coupon every six months and repay the principal in full at maturity, with original tenors of 3 to 30 years.
BNM auctions MGS on behalf of the Government. Successful bidders are those offering the lowest yields, and the coupon is set at the weighted average yield of the successful bids. An auction calendar for the following year is announced at year-end, and the actual issue size is announced a week before each issue. BNM has also offered callable MGS since December 2006.
The Government regularly issues 3-, 5-, 7- and 10-year MGS as benchmarks, and often reopens them to enlarge their size and support liquidity. It has also issued 15- and 20-year MGS to extend the yield curve.
GII is long-term Government paper issued under Shariah principles to fund development expenditure. BNM describes conventional and Islamic Government securities as differing only in structure: their effective cash flows, issuance process and legal status as a direct obligation of the Government are similar.
GII is based on Murabahah, a deferred mark-up sale of an asset such as a commodity (mainly crude palm oil), which creates a debt between the issuer and investors. It pays a profit rate rather than interest.
Issuance runs through BNM's Fully Automated System for Issuing/Tendering (FAST), a central system for originating debt securities by tender or private placement. FAST also holds information on debt securities, is linked to RENTAS for allotment and settlement, and sends information on debt securities to the electronic trading platform (ETP) run by Bursa Malaysia.
Principal Dealers and Islamic Principal Dealers are appointed by BNM for a set period. They underwrite Government and BNM securities sold by tender through FAST and, in the secondary market, must support liquidity by always quoting two-way prices.
Unlisted corporate bonds and sukuk are offered under the Securities Commission Malaysia's (SC) Guidelines on Unlisted Capital Market Products under the Lodge and Launch Framework, first issued on 9 March 2015 and most recently revised on 30 March 2026. Under this framework the issuer lodges the required information and documents with the SC before launch, instead of seeking the SC's approval, provided all the requirements are met.
Government securities trade over the counter. RENTAS (the Real-time Electronic Transfer of Funds and Securities System) is BNM's multi-currency real-time gross settlement system for interbank payments, a securities settlement system and the scripless depository for all unlisted debt instruments. eSSDS, part of RENTAS, computes corporate actions such as coupon payments and handles retail bond issuance.
For pricing, indicative yield-to-maturity contributors appointed by BNM submit daily quotes through FAST for both Government securities and corporate bonds and sukuk by 4.30pm, so that a consolidated rate can be published by 5pm.

MGS are conventional, interest-bearing Government bonds. GII are Shariah-compliant Government securities based on Murabahah that pay profit instead of interest. BNM says their cash flows, issuance and legal status as direct Government obligations are otherwise similar.
The Government of Malaysia issues MGS to finance development expenditure. Bank Negara Malaysia runs the auctions on the Government's behalf, through Principal Dealers using the FAST system.
MGS pay a fixed coupon semi-annually, and the principal is repaid in full at maturity. GII likewise pays profit semi-annually.
RENTAS is BNM's Real-time Electronic Transfer of Funds and Securities System. It is a real-time gross settlement system for interbank payments, a securities settlement system and the scripless depository for all unlisted debt instruments in Malaysia.
Unlisted corporate bonds and sukuk are generally lodged with the SC under its Lodge and Launch framework rather than approved, provided all the requirements of the Guidelines on Unlisted Capital Market Products are met.
