Yield curve edged slightly higher in Sri Lanka’s secondary bond market as investors trimmed positions ahead of next week’s Treasury bond auction, while trading activity remained relatively subdued throughout the session.
Yield curve rises slightly as pre-auction selling pressure weighs on bond trading
Selling interest dominated the market as participants positioned themselves before the Government’s scheduled debt issuance, resulting in moderate upward pressure on yields across key maturities.
In the secondary market, trading was largely concentrated in bonds maturing between 2030 and 2033. Dealers reported that the Yield curve shifted modestly higher as investors adopted a cautious approach ahead of the upcoming T-bond auction, with overall market turnover remaining moderate.
Within the 2030 maturity segment, the Treasury bonds maturing on 15 May 2030, 1 August 2030, and 15 October 2030 traded within a yield range of 11.30% to 11.50%.
Further along the curve, the bond maturing on 1 October 2032 changed hands at 11.65%, while the 1 November 2033 maturity traded within a range of 11.75% to 11.83%, reflecting continued investor demand for longer-dated government securities despite the cautious market tone.
Market participants are now focused on the Treasury bond auction scheduled for 13 July 2026, where the Public Debt Management Office plans to raise Rs. 150 billion through three separate maturities.
The auction will include Rs. 70 billion in 2030 maturity bonds, Rs. 50 billion in 2034 maturity bonds and Rs. 30 billion in 2037 maturity bonds. The sizeable issuance is expected to provide fresh direction for the Sri Lanka bond market, with investors closely watching demand levels and accepted yields for signals on future interest rate expectations.
Ahead of the auction, investors appeared to reduce holdings in selected maturities, contributing to the slight upward movement in the Yield curve. Such positioning is common before large government debt issuances, as dealers seek to manage portfolios and evaluate pricing opportunities before committing fresh funds.
Among actively traded securities, the 1 August 2030 bond recorded an increase of 8 basis points, while the 15 October 2030 maturity moved 9 basis points lower, highlighting mixed investor sentiment within the same section of the yield curve.
On the foreign exchange front, the Sri Lankan rupee weakened against the US dollar. The currency was quoted at Rs. 335.46 per US dollar, compared with Rs. 334.71 in the previous session, reflecting modest depreciation during the trading day.
Meanwhile, liquidity conditions in the domestic banking system continued to improve. Excess liquidity expanded to Rs. 139.01 billion, up from Rs. 125.89 billion previously. The increase in banking sector liquidity provides financial institutions with additional funds available for lending and investment, although market participants remain focused on government borrowing requirements and upcoming debt issuance.
The combination of higher system liquidity, a softer rupee and cautious positioning ahead of the T-bond auction is expected to keep the Sri Lanka bond market closely watched in the coming days. Investors will assess the auction outcome for indications of demand for government securities and whether yields continue to edge higher or stabilise following the issuance.
