Bridging the Global Trade Finance Gap: Structural Causes, Real Economic Effects, and the Promise of Digitalisation

Abstract

Trade finance underpins the great majority of world merchandise trade, yet a large and persistent share of demand for it goes unmet. The Asian Development Bank estimates the global trade finance gap at roughly US$2.5 trillion, with small and medium-sized enterprises (SMEs) and firms in developing economies bearing the heaviest burden. This paper provides a structured review of the trade finance gap, organised around three questions: what drives it, what are its real economic consequences, and which interventions show promise in closing it. Synthesising peer-reviewed empirical research with institutional survey evidence, the review documents the trajectory and distribution of the gap, traces its structural causes to information asymmetries, compliance and prudential costs, paper-based operations, and currency-liquidity constraints, and links the resulting credit rationing to measurable losses in export entry, export volumes, and crisis resilience at the firm level. It then evaluates four pathways to closing the gap (legal and technical digitalisation, financial-technology and supply-chain-finance innovation, multilateral and development-bank programmes, and proportionate regulatory recalibration), paying particular attention to the adoption of electronic transferable records. The review concludes that the gap is less a problem of scarce capital than of frictions in information, law, and process, and sets out an agenda for future research, including improved measurement of the gap and rigorous impact evaluation of digital-trade reforms.
