Understanding Correspondent Tie-Up Agreements (FK-R011, Faisal Khan, September 2026) is a primer on bilateral correspondent structures, the scaling bottleneck they create, and the tri-party arrangements that resolve it.
The headline rule is stated bluntly: for non-bank financial institutions and MTOs, executing a formal tie-up "is a legal prerequisite to moving money across international borders," and a regulator who finds transactions routed through a partner with no signed contract will halt the corridor and issue penalties. Once executed, the agreement stops being paperwork — its terms are programmed directly into both parties' transaction monitoring systems as live configuration, covering transaction limits, KYC triggers, exception handling and financial terms.
What the primer covers:
- Enhanced due diligence before signing: licensing credentials, sanctions screening of beneficial owners and directors, identity verification, and review of AML/KYC manuals — a process taking two to three weeks, sometimes three months
- The scaling bottleneck: each new corridor requires a separate contract, and "the burden scales with the number of countries, not with volume"
- Capital drag: pre-funded balances must be maintained in the local payout bank of every partner, tying up working capital
- Two tri-party models: a commercial aggregator holding pre-existing correspondent agreements, or a sponsored RaaS partner that becomes the regional settlement hub
- The trade-off: tri-party structures concentrate rather than eliminate risk — the aggregator itself needs the same due diligence as a bilateral partner, "and arguably more of it"
