At Risk: South Asia's Regional Trade Integration Under Pressure from Geopolitical Shifts

Executive Summary

South Asia's regional trade architecture, built on the South Asian Free Trade Area (SAFTA) and the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC), is entering a period of heightened uncertainty. Annual review mechanisms built into these agreements, coupled with rising geopolitical pressures, threaten to unravel decades of integration. For the region's economies—where one in five export dollars comes from intra-regional trade—the implications are profound.

Introduction

South Asia, home to nearly 2 billion people and some of the fastest-growing economies, has long pursued regional trade integration as a pathway to collective prosperity. Yet the institutional frameworks remain fragile. The recent decision by several member states to trigger annual reviews of SAFTA through 2035 has injected volatility into trade relations that were designed to reduce tariffs and non-tariff barriers. The interconnected nature of supply chains—from agriculture to textiles to pharmaceuticals—means that any disruption will cascade across borders.

Main Analysis

The Stakes: $30 Billion in Intra-Regional Trade

Current trade flows among South Asian nations exceed $30 billion annually. India, as the largest economy, accounts for approximately 80% of intra-regional exports, while smaller economies like Nepal, Sri Lanka, and Bangladesh depend heavily on market access to India and Pakistan. The agriculture sector is especially exposed: perishable goods, tea, textiles, and pharmaceuticals rely on predictable customs procedures and tariff preferences.

The Review Mechanism: Uncertainty by Design

Unlike the 16-year renewal cycle of NAFTA/USMCA, SAFTA's annual reviews create a recurring source of uncertainty. Each review opens the door for renegotiations, retaliatory tariff adjustments, and stricter rules of origin enforcement. In 2025, for example, India and Bangladesh engaged in a protracted dispute over garment quotas that delayed shipments for months. Such disputes erode business confidence and discourage long-term cross-border investment.

Geopolitical Friction: Trade as a Tool

The rise of bilateral tensions between India and Pakistan, China's growing influence through the Belt and Road Initiative, and the US-China rivalry have turned trade into a geopolitical lever. Sri Lanka's debt crisis and Nepal's political realignments further complicate the regional trade landscape. The 'China factor' looms large, as Beijing offers alternative trade corridors that bypass traditional South Asian frameworks.

Regional Impact

• Economic growth: A breakdown in regional trade could shave 0.5–1 percentage point off GDP growth for smaller economies like Nepal and Bhutan.
• Industrial development: Cross-border supply chains for pharmaceuticals and automotive parts would face costly reconfiguration.
• Trade integration: BIMSTEC ambitions for a comprehensive free trade agreement may stall, hindering connectivity with Southeast Asia.
• Foreign investment: Multinationals sourcing from South Asia would face higher risk premiums, redirecting FDI to more stable regions like ASEAN.
• Supply chain resilience: Over-reliance on the Indian market exposes smaller states to policy shocks; diversification becomes urgent.

Strategic Insights

• Business opportunities: Companies should explore alternative sourcing destinations within South Asia (e.g., Vietnam via BIMSTEC) and invest in compliance capacity to navigate changing rules.
• Corporate strategy: Firms need to develop multi-country production bases to mitigate tariff risks—similar to strategies adopted in North America post-USMCA.
• Policy priorities: Governments must prioritize digital trade facilitation and harmonize standards to reduce non-tariff barriers, which account for 60% of trade costs in the region.
• Regional cooperation: A joint South Asia trade facilitation initiative, funded by the Asian Development Bank, could provide a safety net during review periods.

Future Outlook

Next 3–5 Years

The immediate risks are concentrated in agricultural and textile trade, where tariffs remain sensitive. By 2028, if review processes remain adversarial, South Asia could lose 10–15% of intra-regional trade volume. However, positive scenarios exist: a successful conclusion of BIMSTEC FTA negotiations by 2027 would create a bloc of 1.7 billion people with combined GDP of $4.5 trillion, attracting new investment in logistics and manufacturing.

Technology adoption—particularly in customs automation, blockchain for trade finance, and digital payments—could mitigate some uncertainties. India's Unified Payments Interface (UPI) expansion into Nepal and Bhutan offers a template for lowering transaction costs. Yet the region's underdeveloped digital infrastructure and persistent political distrust remain obstacles.

Conclusion

South Asia's trade integration story is at a crossroads. The annual review mechanism, intended as a safeguard, has become a source of instability. Without concerted political will to institutionalize cooperation—perhaps through a permanent dispute resolution body and a regional investment framework—the gains of the past three decades could erode. For businesses and investors, the message is clear: prepare for volatility but recognize that a more integrated South Asia remains a compelling long-term bet, provided leaders choose cooperation over confrontation.
