The global correspondent banking network has contracted by over a fifth since 2011, with the most acute losses concentrated in small island states and emerging markets, driven by compliance costs and strategic withdrawals by major banks.

The Historic Decline

Correspondent banking relationships globally declined by over 20% from approximately 21,000 active corridors in 2011 to fewer than 16,000 by 2023. Data from the Committee on Payments and Market Infrastructures (CPMI), using SWIFT messaging data, confirms that active correspondent banking relationships fell by roughly 20% between 2011 and 2018 alone. The Financial Stability Board (FSB) reported that from January 2011 to end-2017, the number of active correspondents declined by 15.5% and active corridors by 7.3%. The European Central Bank's eleventh survey on correspondent banking in euro notes that between 2011 and 2018 the decline at the global level stood at 20%.

Regional Disparities

The retreat has not been uniform. According to the Bank for International Settlements (BIS), rates of decline range from 12% to 30% across regions, with Northern America at the low end and Latin America at the high end. The FSB's 2018 progress report to the G20 documents the largest cumulative declines since 2011 in Melanesia and Polynesia (-42.9% and -36.5%, respectively), as well as South America, the Caribbean, and Northern Africa (between -32% and -34%). The Americas excluding North America experienced a 30% decline since 2012, while North America saw a 10% decline.

The BIS notes that for USD transactions specifically, declines are stronger by at least 3.1 percentage points in all sub-continents except Northern America. Oceania recorded a 27% decline in USD relationships—8.1 percentage points more than the overall decline.

Structural Concentration

Despite the sharp drop in relationship numbers, total SWIFT message volumes have risen over the same period, indicating growing concentration in the network. The ECB's survey confirms that the correspondent banking industry remains heavily concentrated, with a few large players accounting for the majority of turnover. There is a clear tendency towards a decreasing role of smaller banks in the correspondent banking business, while larger banks maintain or even expand their activities.

Drivers of Withdrawal

The FSB's 2017 survey of more than 300 banks across nearly 50 jurisdictions identifies two primary drivers. Approximately 40% of respondent banks cited business strategy reassessment as the reason for terminating relationships. Risk-related considerations ranked second, with about 22% of correspondent banks terminating active relationships for reasons linked to compliance and reputation—specifically anti-money laundering and combating the financing of terrorism (AML/CFT) regulations, tax transparency codes, and economic sanctions. About a third of banks reported exiting relationships that were no longer profitable or cost-effective given the required due diligence.

The BIS notes that the retreat is universal yet asymmetrical—smaller countries with less demand, trade, or relative growth experienced a greater decline in relationships than larger, more dynamic markets.

Impact on Affected Jurisdictions

By 2018, 15 jurisdictions had fewer than 20 active correspondent banking relationships each. Some are countries on sanctions lists with low Transparency International scores, but the majority are small island dependent territories with average populations below 200,000. The World Bank confirms that in small island states, the impact of the decline in CBRs has been acute.

The international community has warned that the continuing decline could affect the ability to send and receive international payments, potentially pushing people into unregulated "shadow payments" with consequences for growth, financial inclusion, and international trade. The FSB, IMF, and World Bank have established a four-point action plan to address the issue, with attention now turning to monitoring implementation.

Recent Developments

Data through 2018 indicated that while the decline continued, the annual rate slowed modestly. FSB figures show a year-on-year reduction of 4.1% in the number of active correspondents in 2017, and 2.4% in active corridors. The ECB's 2020 survey noted that over 2011-2018 the most affected regions remain those identified earlier, but the pace of decline had moderated. Total correspondent banking relationship volumes have continued to grow, reinforcing the trend toward a more concentrated, asymmetric network where a dwindling number of correspondent banks serve a widening base of respondent banks.

Outlook

The structural forces driving the decline—compliance costs, risk aversion, and strategic portfolio consolidation—show no signs of reversing. While the international community's action plan may help mitigate the worst effects in vulnerable jurisdictions, the underlying economics of correspondent banking continue to favor concentration. Small island states and emerging markets with limited trade volumes or elevated regulatory risk profiles are likely to remain most exposed. The trajectory points toward a smaller, more concentrated network serving the global payments system, with implications for financial inclusion and cross-border payment costs.
