Cross-border retail and wholesale payments are slow, costly, and fragmented because correspondent banking networks, legacy rails, and inconsistent compliance standards create multiple settlement steps and counterparty risk. The World Bank and Dilip Ratha at the World Bank highlight that remittances and cross-border flows remain expensive relative to the Sustainable Development Goal target of 3 percent, and that those costs disproportionately affect low- and middle-income countries where remittances are a social and economic lifeline. The Bank for International Settlements and Benoît Cœuré at the Bank for International Settlements have documented how fragmentation among domestic payment systems and the lack of interoperability amplify delays and liquidity needs for financial institutions.
How blockchain reduces friction
Blockchain can address several technical causes of cross-border frictions through tokenization of assets, atomic settlement, and shared ledger visibility. Tokenization converts fiat, correspondent balances, or central bank money into cryptographic tokens that can move across platforms without the intermediate reconciliation steps required by correspondent banking. When properly designed, atomic settlement eliminates settlement risk by ensuring the transfer of value and the exchange of information occur simultaneously, reducing the need for pre-funded nostro/vostro accounts and lowering liquidity costs for banks and payment providers.
Permissioned distributed ledgers and standardized message formats improve real-time reconciliation and auditability, which helps compliance with know-your-customer and anti-money-laundering rules if regulatory frameworks accept on-chain proof-of-compliance. SWIFT has noted in its own assessments that faster, more transparent messaging and settlement—achieved through interoperability and standardized data—are key to improving cross-border flows; blockchain can supply the technical layer for those improvements when integrated with established banking processes.
Barriers, consequences, and contextual nuances
Technical promise does not automatically translate into system-wide improvement. International Monetary Fund staff warn that volatility in unbacked crypto assets, weak governance, and insufficient consumer protections create risks that can negate benefits if tokens are not fully backed by credible assets or central bank money. Regulatory misalignment across jurisdictions limits the ability to scale blockchain solutions: AML, sanctions screening, and data residency rules vary by territory, and smaller economies may lack the technical capacity to join complex interoperable networks. Those territorial and cultural factors matter because remittances often support household consumption and local markets in countries such as the Philippines and many economies in Sub-Saharan Africa, where access, trust, and affordability determine adoption.
Environmental and operational consequences also factor into design choices. Permissioned ledgers and central bank digital currency arrangements explored by the Bank for International Settlements and collaborating central banks aim to avoid the high energy footprint associated with some permissionless consensus mechanisms, while pilot programs suggest meaningful reductions in settlement time and costs when governance, liquidity arrangements, and legal frameworks are aligned.
Realizing the potential requires coordinated public-private pilots, legal clarity on tokenized claims, and investment in cross-border standards. Evidence from research and central bank experimentation led by institutions such as the Bank for International Settlements and the World Bank indicates that blockchain can materially improve speed, transparency, and cost-efficiency, but only if technical fixes are paired with regulatory cooperation and protections that reflect local economic and social realities.
