South Asian Crossroads: How Regional Cooperation Could Unlock Trillion-Dollar Growth

South Asia stands at an inflection point, where persistent political friction and fragmented markets suppress a combined economic potential that could rival East Asia. Home to over 1.9 billion people, the region generates a GDP of roughly $4 trillion yet remains one of the world’s least integrated economic corridors. This report examines how historical tensions, infrastructure gaps, and policy inertia have constrained growth, and how a reset in regional cooperation could redefine prosperity for South Asia.

The South Asian Association for Regional Cooperation (SAARC), founded in 1985, was envisioned as a vehicle for shared progress. Yet for decades, the organization has been hamstrung by bilateral disputes, most notably the India-Pakistan conflict over Kashmir. SAARC’s summits have too often concluded with lofty declarations that never translate into binding agreements or measurable outcomes.

The Fragmented Market Puzzle

South Asia’s economic geography is defined by stark asymmetries. India, the region’s giant, accounts for nearly 75 percent of South Asia’s GDP, while smaller neighbors struggle with low domestic demand and limited fiscal space. This imbalance has created a trade landscape where intra-regional commerce represents less than 10 percent of total trade volumes—among the lowest in any major regional grouping.

Trade barriers remain pervasive, even as global supply chains have become more interconnected.

- Customs duties and non-tariff barriers continue to raise costs for cross-border commerce.

- Inconsistent standards and certification requirements force businesses to duplicate testing and compliance.

- Bureaucratic delays at border crossings can add days to transit times, eroding competitiveness.

For example, a Bangladeshi exporter of pharmaceuticals to Nepal may face multiple checkpoints and paperwork requirements that make the journey economically unviable compared to sourcing from farther afield. Similarly, Pakistani textiles struggle to access Indian markets due to restrictive licensing regimes, despite geographic proximity and complementary demand.

Infrastructure: The Missed Connection

Physical connectivity is the most visible symbol of South Asia’s integration deficit. While the region has made strides in expanding ports, roads, and power infrastructure, these assets remain largely domestic in scope. The absence of seamless corridors means that even when policies are favorable, the logistics backbone is not ready to support them.

Consider the case of the Dhaka-Kolkata transit route, which offers a natural bridge between South Asia’s eastern hubs. In practice, bureaucratic hurdles and aging infrastructure have limited its use, forcing higher-cost alternatives.

Power infrastructure illustrates a related challenge. Cross-border electricity trade remains minimal despite shared grids and complementary resources. India’s eastern states have surplus capacity that could benefit Bangladesh and Nepal, yet regulatory frameworks and concerns over grid stability have stalled large-scale projects. Without a coordinated approach to energy infrastructure, the region will continue to suffer from inefficiencies and periodic shortages that undermine industrial output.

The Digital Divide and Innovation Lag

Digital connectivity offers a pathway to leapfrog traditional constraints, yet South Asia’s digital divide is among the widest in the developing world. While India and, to a lesser extent, Bangladesh and Sri Lanka have vibrant tech ecosystems, much of the region remains offline or underserved. High data costs, limited broadband penetration, and fragmented digital regulations prevent small and medium enterprises from accessing global markets.

Startups in Kathmandu or Dhaka often face a steeper climb to reach scale compared to their counterparts in Southeast Asia, where regional payment systems and cross-border e-commerce platforms are more mature. The absence of a coordinated digital policy framework means that innovations in fintech or e-government in one country rarely spread to neighbors.

Security Dilemmas and Their Economic Cost

Security concerns dominate the regional agenda, and for good reason. Historical conflicts, insurgencies, and terrorism have created an environment of mistrust that spills over into economic policymaking. Governments justify protectionist measures as necessary for national security, but the cumulative effect is a market that is smaller and less dynamic than it could be.

This security imperative affects everything from foreign direct investment to people-to-people exchanges. Indian businesses view Pakistan with caution, wary of political volatility that could disrupt supply chains. Meanwhile, Pakistani entrepreneurs see regulatory hurdles when considering ventures in India, even in sectors with potential for synergy, such as textiles or agriculture.

Paths to Integration: What Would It Take?

Transforming South Asia’s economic trajectory requires a multi-pronged strategy that addresses both supply and demand constraints. At the core is the need to depoliticize economic cooperation, creating spaces where technical experts can negotiate without the baggage of broader diplomatic disputes.

Concrete steps could include:

- A phased reduction of tariffs on a wide range of goods, starting with non-sensitive items to build trust.

- Mutual recognition of standards and certifications to lower compliance costs for exporters.

- Joint infrastructure ventures, such as power grids and transport corridors, backed by multilateral financing.

- A regional digital single market with harmonized rules on data flow, e-payments, and cyber security.

Success would not require identical policies, but a shared commitment to convergence where it matters most. Even modest progress could unleash a wave of private investment that has been held back by uncertainty.

Voices from the Region

Policymakers and business leaders across South Asia acknowledge the opportunity, even as they debate the pace and shape of reform.

“We have the people, the resources, and the market,” says a former finance minister from the region, speaking on condition of anonymity. “What we lack is the political courage to prioritize long-term integration over short-term scorekeeping. The cost of isolation is paid by the ordinary worker who cannot access better jobs or cheaper goods.”

This sentiment echoes in chambers of commerce from Colombo to Karachi, where entrepreneurs speak of the potential that remains locked behind borders. For South Asia, the choice is no longer between isolation and integration, but between a gradual, uncertain ascent and a decisive repositioning for global competitiveness. The infrastructure for change exists; what is needed is the collective will to build it.
