What is a banking reliance model?
A reliance model is a documented legal structure under the bank CIP rule — not a description of who happens to run identity checks. Eligibility, contract terms, evidence, and oversight all have to line up.

The short answer.
A banking reliance model is a formally documented arrangement in which a bank relies on another eligible financial institution to perform specified elements of the bank's Customer Identification Program, or CIP, for shared customers.
Reliance is not informal delegation. Under the U.S. bank CIP rule, reliance must be reasonable under the circumstances; the other financial institution must meet specified regulatory conditions; and the parties must enter into a contract requiring annual certification regarding the other institution's anti-money-laundering program and performance of the specified CIP requirements.
31 CFR 1020.220(a)(6)Why financial institutions use reliance structures.
A foreign or domestic financial institution may already maintain a regulated relationship with a business or individual. Repeating every onboarding step can create friction, inconsistent records, and operational duplication.
Where legally permissible and approved, a reliance structure can define how the sponsor bank uses work performed by another eligible institution while preserving the bank's governance, oversight, approval rights, and regulatory responsibilities.
This can be useful when an approved program serves underlying customers that already have a formal banking or financial relationship with the relying institution.
The core regulatory conditions.
The U.S. bank CIP rule provides that a bank's program may specify when it will rely on another financial institution to perform parts of its CIP if:
- 01The reliance is reasonable under the circumstances.
- 02The other institution is subject to an AML-program rule under the Bank Secrecy Act and is regulated by a federal functional regulator.
- 03The other institution contractually agrees to certify annually that it has implemented its AML program and will perform the specified CIP requirements.
These requirements matter. A company should not market a “reliance model” based solely on the fact that it conducts KYC or KYB. Eligibility, regulatory status, contractual allocation, procedures, evidence, testing, and oversight all matter.
What reliance may cover.
The approved agreement and procedures should identify the exact tasks being performed, such as:
- Collecting required identifying information
- Verifying identity through documents or non-documentary methods
- Recording the information and verification results
- Resolving discrepancies
- Providing required customer notices
- Supplying evidence or certifications to the bank
The scope can differ by program. Reliance should never be described more broadly than the actual approved arrangement.
What reliance does not mean.
Reliance does not mean:
- Every regulated financial institution automatically qualifies.
- The sponsor bank gives up approval or oversight.
- The client can change its customer types, jurisdictions, products, or funds flows without review.
- One party has outsourced every compliance obligation.
- Sanctions screening, transaction monitoring, investigations, suspicious-activity escalation, or regulatory reporting are automatically included.
- The client can open accounts for any customer it chooses.
- A registration alone is sufficient evidence of licensing, supervision, or regulatory eligibility.
The parties must separately define beneficial-ownership procedures, sanctions controls, transaction monitoring, recordkeeping, periodic review, and escalation responsibilities.
Reliance compared with direct onboarding.
| Topic | Direct onboarding | Approved reliance structure |
|---|---|---|
| Customer relationship | Bank or program onboards directly | Customer also has a formal relationship with the relying institution |
| CIP work | Performed directly by bank or program | Specified procedures performed by eligible institution |
| Contract | Standard program and customer agreements | Specific reliance terms and annual certification |
| Oversight | Bank retains oversight | Bank still retains oversight and approval rights |
| Eligibility | Based on customer and program | Based on both program and relying-institution eligibility |
| Changes | Subject to normal review | Changes may also require reliance-scope review |

- 06How are discrepancies and failed verification handled?
- 07Who screens customers and transactions against sanctions restrictions?
- 08Who monitors activity after onboarding?
- 09Who investigates alerts and escalates suspicious activity?
- 10How are material program changes approved?
- 11How is the required annual certification produced?
- 12How are quality assurance and testing performed?
How Ledger1 fits.
Ledger1 helps qualified financial institutions define approved account, payment, compliance, integration, reporting, and operating workflows. Where a reliance model is legally available and approved by the applicable bank and program partners, Ledger1 can help coordinate the implementation and ongoing operating model.
Ledger1 does not grant regulatory status, replace required licenses, or guarantee that an institution qualifies for reliance. Eligibility and responsibilities are determined through legal and compliance review and documented in applicable agreements and operating procedures.
Frequently asked questions.
- Is every MSB eligible for a bank CIP reliance model?
- No. The bank CIP reliance rule contains specific requirements regarding the other institution's AML obligations and federal functional regulation. Each proposed structure requires legal, regulatory, and partner review.
- Is reliance the same as outsourcing KYC?
- No. A vendor can provide verification technology without becoming the financial institution on which the bank relies under the CIP rule. Regulatory reliance is a specific legal and contractual structure.
- Does the sponsor bank still approve underlying customers?
- The bank retains the rights, responsibilities, and discretion established in its program agreements and policies. Reliance on specified procedures is not a surrender of bank oversight.
- Does reliance include transaction monitoring?
- Not automatically. Transaction monitoring, sanctions controls, investigations, and reporting must be separately allocated in the approved program documents and procedures.
- Can the relying institution change its onboarding rules?
- Material changes should be governed by change-control procedures and may require prior approval. The approved program should specify how policy, product, jurisdiction, and verification changes are handled.
