Sri Lanka's reserves dip in September despite central bank dollar buying
Sri Lanka's official reserves fell 1.1% to $6.85 billion at the end of September. The central bank bought a net $64.2 million during the month; the rupee has lost 6.3% this year and closed at 330.85 to the dollar on 9 October.
EconomyNext reported on 11 October that official reserve assets fell from $6.929 billion at the end of August to $6.851 billion at the end of September, a drop of about $78 million. Newswire's 8 October report attributes the same figure to the Central Bank of Sri Lanka. It notes that reserves include swap funds with the People's Bank of China, the use of which is subject to conditions. The bank bought a net $64.2 million from the market in September and a net $1,548.8 million in the first nine months of the year.
The rupee closed at 330.85/95 to the dollar on 9 October, down 6.3% since the start of the year, and the yield on the 2034 bond rose to 12.10% the same day. In May, when the fuel import bill from the Middle East squeezed the rupee, the bank sold a net $211 million or more for the first time in 22 months. Analysts say the year-end reserve target of $8 billion can be met with inflows from the IMF and other multilateral lenders in the final quarter.
The external debt calendar is comfortable for now: principal repayments to bondholders begin in April 2028. EconomyNext reported on 8 October that Deputy Finance Minister Anil Jayantha told parliament talks had begun on a new arrangement to follow the $3 billion IMF programme ending in March 2027.
Talay assessment
Bottom line
Sri Lanka is absorbing the oil shock through controlled depreciation and steady dollar buying, not through the reserve depletion of 2022. The bank bought $1.55 billion in nine months, yet reserves are flat, which shows most inflows are going to debt service and the energy bill. The $8 billion year-end target depends on multilateral inflows. The likeliest path is a slowly weakening rupee, with a new IMF framework after March 2027 carrying the burden.
Likely effects
- Exchange rateNegativeWeeks
While the bank buys to build reserves, it is not supporting the rupee; the 6.3% annual loss will keep feeding into fuel and food prices.
- Reserve qualityNegative1–6 months
Chinese swap funds within the $6.85 billion mean usable reserves are lower than the headline figure.
- Debt calendarPositive6 months+
With bond principal repayments not starting until April 2028, there is time to ride out the current shock without a payments crisis.
