Correspondent banking under pressure: consolidation and what comes next
De-risking and rising compliance costs keep shrinking correspondent networks. We explore what continued consolidation means for smaller banks' access to cross-border payment rails.
A decade of de-risking
Over roughly the past decade, industry and regulatory bodies — including SWIFT, the Bank for International Settlements and the World Bank — have documented a steady decline in the number of active correspondent banking relationships worldwide.
The pattern is usually described as "de-risking": banks narrowing their correspondent networks, often stepping back from lower-volume or perceived higher-risk corridors, because the cost and liability of maintaining full compliance coverage across every relationship has grown faster than the revenue those relationships generate.
It is less a single decision than the cumulative result of many institutions each reassessing, corridor by corridor, whether a relationship still earns its keep once compliance overhead is properly accounted for.
Fewer relationships, more concentrated flows
The effect is a consolidation of payment flows through a smaller set of correspondent relationships. For the banks that remain active in a corridor, that concentration can simplify compliance overhead, since due diligence effort is spread across fewer counterparties and each relationship can be managed more closely.
But for the corridor as a whole it can cut the other way: fewer active correspondents can mean higher costs for the payments that still need to move, longer or less direct routing, and less redundancy if one relationship is disrupted.
Managing the relationships that remain
In response, banks are putting more deliberate effort into the correspondent relationships they choose to keep. That includes stronger relationship management practices, closer attention to nostro/vostro liquidity so capital is not left trapped and idle across the network, and tighter alignment with initiatives such as SWIFT gpi and the KYC Registry that reduce friction and duplicated due diligence.
None of this reverses the underlying consolidation trend, which continues to be shaped by broader regulatory and cost pressures, but it does shape how well individual institutions manage the network they are left with — and how much of the cost of consolidation their own customers ultimately feel.
Run Ventures works with banks navigating exactly this environment — managing nostro/vostro liquidity, strengthening the relationships they keep, and aligning with network initiatives that reduce friction across their correspondent footprint.
