Sri Lanka Government Bonds
& Treasury Securities
Sri Lanka’s government securities market — comprising Treasury Bills and Treasury Bonds — offers investors a sovereign-backed, default-risk-free investment avenue with market-determined yields, secondary market tradability, and full repatriation rights for foreign investors.
Sri Lanka’s Government Securities Market
The government securities market is administered by the Central Bank of Sri Lanka (CBSL) and forms the backbone of the domestic debt capital market, providing a benchmark for short-term and long-term interest rates nationwide.
Market Structure
The Government of Sri Lanka raises domestic currency debt primarily for budgetary purposes through two key instruments:
- Treasury Bills (T-Bills): Short-term debt instruments issued under the Local Treasury Bills Ordinance No. 8 of 1923 (as amended)
- Treasury Bonds (T-Bonds): Medium to long-term debt instruments issued under the Registered Stock and Securities Ordinance No. 7 of 1937 (as amended)
Both instruments are issued in scripless form and registered in the Central Depository System (CDS), linked to an automated Scripless Securities Settlement System (SSSS) for real-time settlement.
Regulatory & Monetary Context
Sri Lanka’s Central Bank has undergone transformative governance reform. The new Central Bank Act (September 2023) established a modernized framework emphasizing:
- Full monetary policy independence
- Flexible exchange rate management
- Inflation targeting framework
- Prohibition on monetary financing of government deficits
As of early 2026, the Standing Lending Facility Rate (SLF) stands at 9% and the Standing Deposit Facility Rate (SDF) at 8%, following cautious monetary easing from peak crisis rates.
✅ Recovery Milestone: Following the severe 2022 economic crisis and IMF-supported restructuring, Sri Lanka has significantly strengthened its fiscal position. Gross official reserves reached approximately US$6.1 billion by end-2024 (up from US$4.4 billion at end-2023). Government tax revenues rose 21% in the five months to May 2025, reaching LKR 1.804 trillion. A primary budget surplus has been achieved and sustained.
Treasury Bills (T-Bills)
Treasury Bills are Sri Lanka’s primary short-term government debt instruments, offering high liquidity, sovereign backing, and a market-determined return with no withholding tax.
Key Features of Treasury Bills
Discount Pricing
Treasury bills are normally issued at a discount and repaid at face value at maturity. The difference between purchase price and face value represents the investor’s return — currently exempt from withholding tax under Sri Lankan law.
Secondary Market Tradability
T-Bills are fully tradable in the secondary market through licensed banks and Primary Dealers, making them highly liquid money market instruments and a superior alternative to fixed deposits for institutional cash management.
Benchmark Rate Function
Interest rate movements in the Treasury bill market provide a benchmark for the short-term credit market throughout Sri Lanka’s financial system, influencing the cost of borrowing for both banks and corporates.
Open Market Operations Collateral
T-Bills and T-Bonds are accepted as collateral by the Central Bank under its Open Market Operations (OMO), ensuring banks and financial institutions can use them for short-term liquidity management.
Current Rate Environment
Rate Trajectory: The Central Bank has cautiously eased policy rates following peak crisis rates. With inflation remaining subdued and the IMF programme on track (4th review completed July 2025 with US$350M disbursement), a stable-to-easing rate environment is expected through 2026, supporting bond prices.
Treasury Bonds (T-Bonds)
Treasury Bonds offer investors medium to long-term fixed income exposure backed by Sri Lanka’s sovereign credit, with semi-annual coupon payments and maturities from 2 to 30 years.
