Foreign investors have resumed selling Sri Lanka’s rupee-denominated government securities, raising fresh questions about currency stability, inflation management and the sustainability of capital inflows as the country continues its economic recovery. Although foreign investment in government bonds remains positive for the year, recent outflows highlight the vulnerability of Sri Lanka’s financial markets to exchange-rate pressures and international uncertainty.
Central Bank data show that offshore investors sold a net Rs. 2.818 billion, equivalent to approximately US$8.5 million, in rupee-denominated government bonds during the week ended October 23, 2026. This marked the first weekly net selling in four weeks and extended net foreign outflows to Rs. 13.8 billion over the preceding six weeks.
he latest withdrawal followed net foreign purchases of Rs. 5.5 billion during the previous three weeks, illustrating how quickly investor sentiment can change when currency risks intensify.
However, the broader picture is not entirely negative. Sri Lanka has attracted approximately Rs. 58.3 billion in net foreign inflows into local-currency government bonds so far this year, following net inflows of Rs. 71.5 billion in 2025. Foreign investors have been net sellers in only three of the past 19 weeks, suggesting that the latest reversal does not, by itself, establish a sustained withdrawal from the market.
Nevertheless, the deterioration warrants close monitoring because foreign portfolio investment can reverse rapidly when investors anticipate currency depreciation, rising inflation or deteriorating global financial conditions.
The rupee has depreciated by 6.7% through October 27 this year. Analysts have linked recent bond selling to downward pressure on the currency, while the Central Bank has previously cited higher oil and vehicle imports amid continuing Middle East tensions as contributing factors.
This combination exposes a central weakness in Sri Lanka’s external position: foreign-currency demand can rise sharply when essential energy imports become more expensive, while portfolio investors simultaneously reassess the returns available from rupee assets.
A weaker rupee increases the local-currency cost of imported fuel, machinery, medicine and other essential goods. Businesses may pass those costs on to consumers, adding to household expenses and potentially undermining the purchasing power of wages and savings. Higher import costs can also increase pressure on foreign-exchange demand and complicate efforts to maintain price stability.
Inflation has accelerated over the past six months following an almost 50% increase in fuel prices. The Government raised fuel prices again in the final week of September after reducing them in June and August, demonstrating the continuing tension between cost-reflective pricing and household affordability.
The Central Bank raised its policy rate by 100 basis points in May to counter inflationary pressures associated with stronger demand. Before that decision, policy rates had remained unchanged since May 2025, following cumulative reductions of 825 basis points over the preceding two years.
Higher interest rates may improve the relative attractiveness of rupee investments, but they can also increase borrowing costs for businesses and households, potentially slowing private investment and consumption.
The critical question is whether Sri Lanka can sustain foreign investor confidence through stronger export earnings, disciplined public finances, adequate reserves and predictable monetary policy, rather than relying excessively on interest rates to defend the currency.
The latest bond outflow is not proof of an impending financial crisis. It is, however, a warning that positive annual investment figures can conceal emerging vulnerabilities. Policymakers must monitor portfolio movements alongside the trade deficit, foreign-exchange reserves, inflation and external debt obligations to determine whether currency pressures are temporary or becoming structural.
