Navigating the CSE in Q3 2026 as Foreign Capital Exits

Late February 2026 is the hinge point for this entire story. The Central Bank of Sri Lanka has repeatedly dated the onset of external sector pressure to the emergence of the Middle East conflict that month, and the timing lines up with a shift in foreign investor behavior across both the equity and bond markets.

Foreign investments in the CSE, covering both primary and secondary market transactions, recorded a net outflow of US$ 30 million in February 2026. That figure alone would not alarm anyone; monthly swings of that size are routine on a frontier exchange. What made it notable was the direction it set. Gross official reserves, including the swap facility with the People's Bank of China, still rose to US$ 7.3 billion at the end of February, helped by Central Bank foreign exchange purchases even as debt service payments continued.

Tourist arrivals told a different, more resilient story that month, up 16.3% year on year, with earnings estimated at US$ 352 million. Workers' remittances also sustained a positive trend. In other words, the current account was not the source of stress. The stress was arriving through the financial account, in the form of portfolio money heading for the exits.

By March 2026, the outflow had spread from equities into government debt, and this is the month the brief for this piece specifically flags for a reason. Foreign investments in the government securities market recorded a net outflow of US$ 64 million during March, a sharper monthly figure than the equity-side outflow the month before.

Rupee depreciation accelerated in step. By the end of March, the Sri Lanka rupee had weakened 1.6% against the US dollar on a year-to-date basis. That is not a large number in isolation, but the Central Bank's own commentary linked it explicitly to the emergence of external sector pressure tied to the conflict, not to any domestic policy shift.

Gross official reserves fell to US$ 7.0 billion at end March, a decline the Central Bank attributed mainly to external debt service payments rather than reserve defense through the currency market. For bond traders, the practical effect was straightforward: with foreign holders trimming positions, yields on government securities came under upward pressure even though the Monetary Policy Board had kept its policy rate unchanged earlier in the year. A rising-yield, falling-foreign-participation environment is exactly the kind of setup that eventually feeds back into equity valuations, because it changes the discount rate every local fund manager is using.

April brought no reversal. By the end of April 2026, the rupee had depreciated 2.9% against the US dollar year to date, continuing the slide that began in March. The Central Bank again pointed to external sector pressures following the onset of the Middle East conflict as the primary driver, rather than any single domestic event.

This is also where the multi-year context matters. Foreign investors were not arriving fresh to a market they liked and then abruptly leaving. Many had already been trimming Sri Lankan exposure since the 2022 default and the subsequent restructuring process, and the 2026 outflow layered on top of that earlier, slower retreat. A trader looking only at the headline monthly figures for February through May would miss that the base of foreign ownership on the CSE was already thinner than it had been a decade earlier, which makes each subsequent month of selling proportionally more visible in the flow data even when the absolute rupee amounts are modest by global standards.

Services account performance softened in step. The services surplus had already declined 16.7% year on year in February, and the trend did not meaningfully improve through April, reflecting both tourism earnings pressure and elevated overseas travel spending pulling in the opposite direction.

May 2026 is the month the brief's headline figure references, and the Central Bank's own reporting confirms outflows were live in both markets at once. Foreign investments in government securities recorded a net outflow of US$ 60 million in May, while foreign investments in the CSE, across primary and secondary transactions, recorded a net outflow of US$ 23 million for the same month.

Reserves continued to soften, standing at US$ 6.9 billion by end May, though the decline was cushioned by the joint disbursement of the sixth and seventh tranches under the IMF Extended Fund Facility. Without that programme support, the reserve drawdown from debt service payments and Central Bank foreign exchange sales would have been more visible.

Cumulative pressure on the currency kept building. By end June, the rupee had depreciated 7.9% against the US dollar on a year-to-date basis, more than double the pace recorded just three months earlier. That acceleration is the clearest signal that the Middle East conflict's spillover into Sri Lankan markets was not a one-month scare but a sustained repricing of risk that ran through the entire first half of the year, consistent with the cumulative net foreign equity outflow figures reported for the January-to-May period.

Not every indicator moved the wrong way. Tourist arrivals for the first five months of 2026 surpassed one million, up 9.6% year on year in May alone, and workers' remittances reached US$ 847 million that month, extending a favorable multi-month trend. The outflow story sits inside a broader external account that was still receiving healthy inflows from tourism and remittances even as portfolio capital left.

Here is the part that surprises traders who assume foreign selling automatically means a falling index: it did not, at least not in a straight line. January 2026 opened with genuine strength, with the ASPI gaining 5.25% and the S&P SL20 climbing 7.86% for the month, supported by a near-doubling of investor participation compared to December.

Local liquidity, not foreign flows, has been doing most of the work on the CSE this year. Average daily turnover jumped from roughly LKR 3.66 billion to LKR 7.09 billion between December 2025 and January 2026, and domestic institutional and retail participation has continued to anchor trading sessions since. Banking sector counters in particular have repeatedly led the ASPI's positive contributors on individual sessions through the second quarter.

By early July 2026, the ASPI was trading in the 21,800 to 22,000 range and remained up roughly 20% compared to the same period a year earlier, even after the string of foreign outflows. The S&P SL20 has moved in a comparable band, dipping under 6,100 on some sessions in July and holding above 6,200 on others, tracking company-specific news, particularly among banking and conglomerate counters, at least as much as it tracks the foreign flow data.

Treasury bill yields, meanwhile, have been described by the Public Debt Management Office as broadly steady into July auctions, even after the March and May government securities outflows. That stability suggests domestic demand for government paper has been sufficient to absorb the foreign selling without forcing a disorderly repricing, though the underlying pressure has not disappeared.

None of the above is a signal to buy or sell any specific counter; it is a map of the forces retail traders are navigating. A few practical distinctions are worth drawing before the next earnings season lands.

• Separate currency drag from company fundamentals. A blue-chip counter that is losing foreign holders because global funds are de-risking is a different situation than one losing holders because its underlying business is deteriorating. Reading company filings and sector-specific news alongside the CBSL's monthly external sector releases helps tell the two apart.
• Watch turnover composition, not just the index level. The CSE has stayed resilient in 2026 largely because local turnover has been strong. If daily crossings and retail participation start thinning at the same time foreign selling continues, that combination would matter more than either factor alone.
• Track the rupee alongside the index. A 7.9% year-to-date depreciation by June changes the return calculus for anyone comparing CSE performance to dollar-denominated alternatives. Local currency gains can mask a smaller, or even negative, dollar return for the period.
• Use the Central Bank's monthly external sector releases as a scheduled checkpoint. They arrive roughly a month after each reference period and give a clean, primary-source read on whether foreign selling is accelerating, steady, or easing, rather than relying on session-by-session commentary alone.
• Treat banking and insurance counters as a bellwether, not a safe harbor. These sectors have repeatedly led both gains and losses on the ASPI through 2026, making them useful for reading market sentiment even for traders who hold other counters.

Sri Lanka enters the third quarter with reserves near US$ 6.9 billion, IMF programme support still flowing, and an equity market that has absorbed five straight months of foreign selling without a disorderly break. That is a more stable starting point than the headline outflow figures suggest on their own.

The conditional case for Q3 splits two ways. If the Middle East conflict persists or widens through the third quarter, expect continued foreign selling pressure on both the CSE and government securities, further gradual rupee depreciation, and yields that stay elevated relative to where they sat before February. In that scenario, local liquidity and banking-sector strength will need to keep doing the heavy lifting to hold the ASPI and S&P SL20 in their current ranges.

If the conflict de-escalates or global risk appetite stabilizes instead, the reverse dynamic becomes plausible: foreign investors who have been net sellers since February could return as buyers looking for value in blue chips that never actually lost their underlying earnings power, only their foreign ownership base. Either path keeps the same variables in view for the rest of 2026: the monthly CBSL external sector release, the direction of the rupee, and whether domestic turnover keeps carrying the market the way it has for most of this year.
