Excess liquidity in the banking system fell to LKR 278.51 billion, even as Treasury bill yields eased across all tenors at the latest auction.
Excess liquidity in Sri Lanka’s banking system contracted to LKR 278.51 billion, down from LKR 300.25 billion the previous week, a decline of roughly LKR 21.7 billion, or 7.2%.
The tightening in liquidity comes even as short-term Treasury bill yields moved lower across all tenors at the August 20 auction, with the 91-day rate falling 22 basis points to 9.22%. Foreign holdings of rupee-denominated government securities rose 0.70% week-on-week, reaching LKR 194.21 billion, continuing a steady upward trend recorded over the past several weeks of data.
Total outstanding government securities stock stood at LKR 18,635.21 billion, broadly flat week-on-week at -0.02%, comprising LKR 16,279 billion in Treasury bonds and LKR 2,357 billion in Treasury bills.
On the secondary market, buying interest was recorded in select 2028, 2034, 2036 and 2037 maturities, with yields along the curve ranging from roughly 10.05% at the short end to 12.00% at the 2036 and 2037 maturities. Trading volumes across the secondary market were described as moderate for the session.
Business Impact: A tightening in system-wide liquidity can influence short-term interbank funding costs and banks’ capacity for credit expansion, a factor relevant to businesses relying on bank credit lines. The contraction is worth monitoring against the backdrop of falling Treasury bill yields — a combination that will shape the direction of short-term rates in the sessions ahead. The steady rise in foreign holdings of government securities, meanwhile, points to continued external interest in local currency debt.
What to Watch Next: Liquidity trends into the upcoming T-bond auction on August 25 will be a key indicator of whether the tightening is a short-term fluctuation or the start of a more sustained shift, with implications for pricing on the LKR 50 billion in bonds on offer.
