Equity turnover slipped 18.8% even as trading volume rose, while short-term government securities yields declined and the rupee firmed against the dollar.
The Colombo Stock Exchange closed marginally higher, with the All Share Price Index (ASPI) adding 10.99 points to end at 21,416.61, a gain of 0.05%. The S&P SL20 index rose 8.84 points, or 0.15%, to close at 6,028.09.
Market turnover totaled LKR 1,219.22 million (approximately USD 3.64 million), down 18.8% from the previous session, even as trading volume rose 23.2% to 50.28 million shares. The Capital Goods sector accounted for 39% of turnover, with Materials and Banking together contributing a further 27%. SIRA was the single largest contributor to turnover at 24%.
Foreign investors were net sellers of equities, with a net outflow of LKR 58.16 million on the day. On a cumulative basis, foreign flows remain negative for both the month (-LKR 18.59 billion MTD) and the year (-LKR 54.87 billion YTD).
In fixed income, Treasury bill yields fell across all tenors at the August 20 auction: the 91-day rate declined 22 basis points to 9.22%, the 184-day fell 18 basis points to 9.60%, and the 364-day dropped 10 basis points to 9.91%. In the secondary market, increased trading activity was recorded in select 2028, 2034, 2036 and 2037 maturities, with yields along the curve ranging from approximately 10.05% at the short end to 12.00% at the longest tenors traded. Banking system liquidity contracted to LKR 278.51 billion from LKR 300.25 billion in the prior week.
The rupee appreciated against the US dollar, closing at LKR 330.17 compared to LKR 331.23 previously.
Business Impact: Falling short-term Treasury yields point to easing near-term borrowing costs, a relevant signal for businesses managing working capital and short-term debt. The continued net foreign equity outflow, both month-to-date and year-to-date, remains a factor for market liquidity and valuation sentiment, though today’s single-day figure was modest. The rupee’s slight firming offers marginal relief for importers managing USD-denominated costs.
What to Watch Next: The T-bond auction scheduled for August 25 (offering LKR 30 billion in the 2030 maturity and LKR 20 billion in the 2035 maturity) will provide a further read on longer-term rate direction and investor demand for government debt.
