Over the past decade and a half, the global correspondent banking landscape has undergone a structural transformation. Much of the public discussion has centred on de-risking and the withdrawal of correspondent relationships from emerging and frontier markets. While access remains an important concern, the more consequential issue in 2026 is not merely the availability of USD correspondent banking relationships, but their concentration.

Data published by the Bank for International Settlements (BIS) indicates that between 2011 and 2022, the total number of correspondent banking relationships globally declined by approximately one quarter. Updates through 2024 and 2025 show that while the pace of contraction has slowed, the network remains structurally smaller than in the pre-2014 period. SWIFT data reflects a similar pattern in that cross-border payment volumes have continued to grow, yet flows are increasingly concentrated among a reduced number of global clearing institutions. This has resulted in what can be called structural consolidation. 

For emerging market banks, this consolidation has an array of implications. Many institutions maintain a single primary Tier-1 USD correspondent, and these relationships may function without disruption for extended periods, leaving trade finance instruments available for use and liquidity readily available. 

However, concentration risk in correspondent banking does not typically present itself as an abrupt termination, but tends to manifest incrementally in the form of expanded due diligence requirements, lengthening documentation cycles, and the introduction of informal volume guidance. While these changes may not constitute formal de-risking events, they affect liquidity flexibility and certainty.

The drivers of this environment are well documented. Since the global financial crisis, enforcement actions related to AML, sanctions compliance, and counter-terrorist financing have materially altered risk appetites within global banks. FATF mutual evaluation processes have intensified, and jurisdictions placed under increased monitoring frequently experience heightened correspondent scrutiny. Geopolitical fragmentation and evolving sanctions regimes have further elevated sensitivity around cross-border USD flows.

Within this framework, USD correspondent access is better understood not as a relationship to be maintained, but as financial infrastructure to be designed.

Experience advising emerging market institutions, including work undertaken by Tana Capital across Central Asia, the Caucasus, and parts of the Middle East, suggests that many banks approach correspondent banking from a tactical stance. The focus is often on securing or preserving a specific relationship rather than evaluating the structural resilience of access architecture. Yet resilience depends less on the longevity of a single correspondent and more on the distribution of exposure across clearing channels and governance systems.

When correspondent banking is treated as infrastructure, attention shifts toward the diversification of clearing pathways, the alignment of internal AML/KYC frameworks with Tier-1 audit standards, and the integration of correspondent strategy into treasury and capital planning processes. Where appropriate, structured nested arrangements may complement direct correspondent lines, provided transparency and compliance governance are robust. The objective should not be duplication for its own sake, but rather the development of a redundancy sufficient to absorb the impacts of recalibration within a concentrated global network.

Trade finance implications are particularly significant. Letters of credit, standby instruments, guarantees, and documentary collections depend fundamentally on reliable settlement mechanisms and counterparty confidence. Concentration at the correspondent level can translate into delays, confirmation hesitancy, or increased collateralisation requirements. Even in the absence of formal restrictions, counterparties may reassess exposure if settlement pathways appear overly dependent on a single institution.

The broader trade finance gap, as documented in surveys by the International Chamber of Commerce and development institutions, is a sure sign of persistent constraints in developing markets. Compliance-related considerations remain a leading cause of rejected transactions, and concentrated correspondent structures may indirectly amplify these constraints by limiting flexibility.

From a governance perspective, correspondent concentration risk warrants board-level attention. Executive committees should evaluate the degree of dependency on individual clearing partners, the feasibility of alternative arrangements, and the alignment of internal compliance controls with evolving global standards. These considerations intersect directly with liquidity management, capital efficiency, revenue growth capacity, and reputational stability.

Establishing additional correspondent channels requires investment in compliance systems, technology integration, and ongoing monitoring. Smaller institutions may face scale limitations. Nevertheless, the continued consolidation of global flows suggests that concentration carries long-term strategic risk.

Looking ahead, correspondent banking evolution is unlikely to be characterised primarily by sudden exits. More consequential may be incremental adjustments of risk appetite within global institutions as regulatory expectations, geopolitical dynamics, and sanctions frameworks evolve. In a system where USD clearing is concentrated among a relatively small number of global banks, architectural resilience at the institutional level becomes critical.

In 2026, the strategic imperative for emerging market banks is therefore clear. Correspondent banking should not be approached solely as access to secure, but as an infrastructure to engineer. Structural resilience, rather than relationship tenure alone, will define institutional stability within an increasingly consolidated global payments network.
