Sri Lanka vs Vietnam, Bangladesh, Pakistan: Frontier Markets Compared

Frontier equity markets in these four economies trade at widely different multiples relative to their economic size. Vietnam’s stock market capitalization reached $220 billion in 2025, or about 51% of GDP. Sri Lanka stood at $19.7 billion (19.7% of GDP), Bangladesh at $88 billion (19.5% of GDP), and Pakistan at $50 billion (14% of GDP).

Here is the kicker: lower market-cap-to-GDP ratios in Sri Lanka, Bangladesh, and Pakistan signal underdeveloped domestic equity participation compared with Vietnam. Trailing P/E for Vietnam sits at 18.0 as of February 2026, viewed as fair relative to its five-year average. Data for the other three remain scarcer but generally cluster in single digits for many constituents, reflecting post-crisis recovery pricing.

What sets them apart is earnings growth visibility. Vietnam benefits from manufacturing relocation and export momentum that support higher multiples. Sri Lanka’s Colombo Stock Exchange has posted strong rebounds, yet absolute liquidity stays thin. Bangladesh and Pakistan show even lower penetration, leaving room for domestic retail and institutional deepening.

Why this matters: investors scanning for value often start with these depressed ratios, yet must factor in corporate governance and foreign-ownership caps that differ across jurisdictions.

Vietnam continues to outpace the pack. World Bank figures show 7.1% expansion in 2024, 7.2% estimated for 2025, and 6.3% projected for 2026. Sri Lanka posted 5.0% in 2024, moderating to 4.6% in 2025 and 3.5% in 2026 as the post-crisis rebound normalizes.

Bangladesh’s fiscal-year growth (ending June) reads 4.2% for FY2024, 3.7% for FY2025, and 4.6% for FY2026. Pakistan hovers near 3.0% for FY2025/26 with a modest lift to 3.4% the following year, per World Bank assessments. IMF October 2025 snapshots align broadly with these ranges.

Demographics and policy execution explain the spread. Vietnam’s integration into global supply chains drives sustained momentum. Sri Lanka’s recovery rests on tourism, remittances, and fiscal consolidation. Bangladesh leverages garments and remittances but faces export softness. Pakistan contends with structural reforms and external financing needs.

Why this matters: GDP growth alone does not guarantee equity returns, yet it underpins corporate revenue potential and fiscal space for market-friendly policies.

Sovereign credit ratings reveal clear hierarchy. S&P assigns Vietnam BB+ with stable outlook. Bangladesh sits at B+ (Moody’s B2). Pakistan carries B- (Moody’s Caa1). Sri Lanka holds CCC+ (Moody’s Caa1), upgraded from selective default in 2025 but still deep in speculative territory.

Political and external risks vary. Vietnam enjoys policy continuity and diversified trade partners. Sri Lanka has stabilized reserves and inflation after 2022 turmoil, yet debt servicing remains sensitive. Bangladesh navigates post-election transitions and climate vulnerabilities. Pakistan balances IMF programs with domestic political cycles.

Currency volatility and capital controls add layers. All four operate managed floats with occasional intervention. Vietnam’s dong has shown relative steadiness amid export strength. The others experienced sharper swings during global rate hikes or domestic shocks.

What sets them apart: Vietnam’s higher rating correlates with deeper institutional buffers and FDI resilience. Lower-rated peers offer higher risk premia that may compensate patient capital during stabilization phases.

Foreign direct investment patterns diverge sharply. Vietnam captured record ASEAN inflows in recent years, fueled by supply-chain shifts. Sri Lanka reported an 18% rise in investment proposals in the first half of 2025, with greenfield projects from Asia and Europe. Bangladesh and Pakistan attract steady but smaller volumes, often concentrated in textiles or infrastructure via bilateral channels.

Portfolio flows remain episodic. Vietnam’s market sees regular institutional interest ahead of potential emerging-market index upgrades. Sri Lanka’s CSE has drawn selective foreign buying on recovery signals, though net positions stay modest. Bangladesh and Pakistan experience thinner daily liquidity and occasional repatriation waves tied to global risk sentiment.

Domestic participation differs too. Vietnam boasts broader retail engagement. Sri Lanka, Bangladesh, and Pakistan rely more heavily on high-net-worth and institutional locals, with pension and insurance sectors still growing.

Why this matters: sustained foreign inflows can improve liquidity and governance standards, yet sudden exits amplify volatility in smaller markets. Regulatory easing on foreign ownership remains a watched variable across all four.
