FDIC Rules on Brokered Deposits

The Federal Deposit Insurance Corporation's regulations governing brokered deposits form one of the most consequential—and frequently revised—corners of U.S. banking law. These rules determine how deposits gathered through third-party intermediaries are classified, how they affect a bank's regulatory standing, and what rate caps apply when a bank's capital falls below well-capitalized thresholds. Understanding the mechanics matters because misclassification can trigger immediate supervisory consequences and alter a bank's deposit insurance assessment costs.

Definition and scope

Under 12 U.S.C. § 1831f, a brokered deposit is any deposit that is obtained by a depository institution through the mediation of a deposit broker. A deposit broker is defined as any person who is engaged in the business of placing deposits, or facilitating the placement of deposits, at insured depository institutions on behalf of a third party. The statutory definition is broad by design, capturing both traditional broker-dealers who sweep client cash into bank accounts and fintech platforms that route consumer funds to partner banks.

The FDIC's current regulatory framework, overhauled through a final rule published in the Federal Register on January 22, 2021, modernized a regime largely unchanged since the Financial Institutions Reform, Recovery, and Enforcement Act of 1989 (FIRREA). The 2021 rule introduced a two-part test for determining whether a given arrangement produces a brokered deposit and created a formal applicability process for institutions and third parties seeking determinations.

The scope of the rules extends to all FDIC-insured institutions. Credit unions supervised by the NCUA are outside its reach, but any bank or thrift with federal deposit insurance — numbering approximately 4,600 institutions as of the FDIC's own data in FDIC Statistics on Depository Institutions — must evaluate every third-party deposit channel against the brokered deposit definitions.

Core mechanics or structure

The 2021 rule's central innovation is a two-prong analysis for determining whether an entity constitutes a deposit broker:

1. Prong 1 – Placement: Does the entity place deposits at more than one bank on behalf of others?
2. Prong 2 – Primary purpose: Is the primary purpose of the entity's business relationship with its customers the placement of funds at depository institutions?

If an entity fails the primary purpose exception — meaning deposit placement is the primary purpose — the deposits it channels are brokered. If an entity qualifies for a primary purpose exception (PPE), the deposits may fall outside the brokered deposit definition entirely.

The FDIC established two pathways to qualify for a PPE:

• 25% test: If less than 25% of the total assets under administration or total funds placed by the entity are placed at depository institutions, the entity qualifies automatically.
• Designated business exception (DBE): Entities whose primary purpose is a business other than deposit placement may apply to the FDIC for a case-by-case determination. The FDIC published a list of pre-approved business models — including broker-dealers sweeping uninvested cash balances and certain payroll processors — that qualify without individual application.

Once deposits are classified as brokered, the bank must report them in Call Report filings. Well-capitalized institutions may accept brokered deposits without restriction. Adequately capitalized institutions require a waiver from the FDIC before accepting any brokered deposits. Undercapitalized institutions are categorically prohibited from accepting brokered deposits, per 12 U.S.C. § 1831f(c).

Causal relationships or drivers

The brokered deposit restrictions exist because of a direct causal link, documented extensively in post-1980s banking research and FDIC historical analyses, between rapid brokered deposit growth and bank failure rates. Brokered deposits enabled banks with weakening balance sheets to continue attracting funds at above-market rates, accelerating asset growth without corresponding improvements in credit quality. The savings and loan crisis, in which the FDIC and predecessor insurance funds paid out over $150 billion in resolution costs (per FDIC History of the Eighties, Vol. I), provided the empirical basis for § 1831f's restrictions.

The causal chain operates in multiple directions. A bank's capital ratio drives its permissible brokered deposit activity. A decline in capital status — from well-capitalized to adequately capitalized — immediately restricts deposit-gathering options. Reliance on brokered deposits, in turn, affects the FDIC's deposit insurance assessment formula: brokered deposits represent a liability concentration that increases an institution's risk score, raising premiums paid into the Deposit Insurance Fund.

Banks that rely heavily on brokered deposits also face liquidity volatility. Because broker-placed deposits are rate-sensitive and often short-term, they can exit quickly when a bank's condition deteriorates or when interest rate spreads shift — a dynamic the FDIC's Risk Management Manual of Examination Policies identifies as a liquidity concentration risk.

Classification boundaries

Classification is not always binary. The 2021 rule created a matrix of outcomes:

Deposit broker status:
- An entity is a deposit broker if it places deposits at multiple banks and deposit placement is the primary purpose of its customer relationship.
- An entity is not a deposit broker if it qualifies under the 25% test or an approved designated business exception.

Deposit treatment:
- Deposits placed by an entity that is not a deposit broker are not brokered deposits, regardless of how they reach the bank.
- Deposits placed by a confirmed deposit broker at a well-capitalized bank are brokered but permissible.
- Deposits placed by a confirmed deposit broker at an adequately capitalized bank require an FDIC waiver under 12 CFR § 337.6.

Interest rate restrictions:
Separately, adequately capitalized and undercapitalized institutions face rate caps. The rate cap for brokered deposits is tied to the national rate — defined as the average of rates paid by all insured depository institutions — plus 75 basis points. Non-brokered deposits at less-than-well-capitalized banks are capped at the local market rate or the national rate plus 75 basis points, whichever is higher. The FDIC publishes updated national rate data weekly at FDIC National Rates and Rate Caps.

Tradeoffs and tensions

The brokered deposit framework generates genuine regulatory tension between competing legitimate interests.

Access vs. safety: Community banks and fintech-bank partnerships argue that brokered deposit restrictions limit access to stable funding channels and disadvantage smaller institutions relative to large banks with diversified retail franchise networks. The FDIC acknowledged this tension explicitly in the preamble to the 2021 final rule, creating the primary purpose exception framework partly in response to industry comments about fintech partnerships.

Complexity vs. clarity: The two-prong test resolved some ambiguity from prior guidance but introduced new interpretive questions. Determining whether an entity's "primary purpose" in a customer relationship is deposit placement requires fact-specific analysis that can differ across business models. The FDIC's designated business exception list provides safe harbors, but novel arrangements still require case-by-case applications.

Assessment costs vs. funding flexibility: Brokered deposit classification raises a bank's risk-based assessment rate under 12 CFR Part 327. This creates incentive for banks to structure third-party arrangements to avoid brokered deposit treatment — an optimization pressure that regulators must monitor for regulatory arbitrage.

The FDIC's bank examination process includes review of deposit composition precisely because these classification decisions carry direct supervisory consequences.

Common misconceptions

Misconception 1: All third-party deposits are brokered deposits.
Incorrect. The two-prong test means that a payment processor, payroll platform, or bank-as-a-service partner whose primary business purpose is not deposit placement may not qualify as a deposit broker at all. Only deposits flowing through entities meeting the statutory deposit broker definition are subject to § 1831f restrictions.

Misconception 2: Well-capitalized banks have no restrictions on brokered deposits.
Partially incorrect. Well-capitalized banks may accept brokered deposits without FDIC approval, but brokered deposit volumes still affect the bank's deposit insurance assessment score. Higher brokered deposit ratios increase the risk-based premium paid into the Deposit Insurance Fund, so unrestricted acceptance does not mean cost-free acceptance.

Misconception 3: The national rate cap applies only to brokered deposits.
Incorrect. Under 12 CFR § 337.6(b), interest rate restrictions apply to all deposits accepted by less-than-well-capitalized institutions — not only brokered deposits. Non-brokered deposits at adequately capitalized banks are also subject to rate caps, measured against the prevailing local market rate.

Misconception 4: Once classified, brokered deposit status is permanent.
Incorrect. Classification follows the status of the deposit broker and the depositing institution at the time of acceptance and ongoing reporting periods. If a third-party entity restructures its business to qualify for a primary purpose exception, subsequently placed deposits may no longer be brokered. Banks must reassess classifications periodically and when material changes occur in third-party arrangements.

Checklist or steps (non-advisory)

The following sequence reflects the analytical steps embedded in FDIC regulations and guidance for evaluating whether a deposit is brokered:

1. Identify the deposit channel — Determine whether a third party was involved in soliciting, placing, or facilitating the deposit.
2. Apply the deposit broker definition — Assess whether the third party meets the statutory definition under 12 U.S.C. § 1831f: engaged in the business of placing or facilitating placement of deposits at more than one insured institution.
3. Evaluate Prong 1 (placement activity) — Confirm whether the entity places deposits at more than one bank on behalf of customers.
4. Evaluate Prong 2 (primary purpose) — Determine whether the primary purpose of the entity's relationship with its customers is deposit placement.
5. Check the 25% test — If less than 25% of assets under administration are placed at banks, the entity may qualify for an automatic primary purpose exception.
6. Check the designated business exception list — Compare the entity's business model against FDIC-approved DBE categories published in the 2021 final rule.
7. Submit an application if needed — If neither automatic exception applies, submit a PPE application to the FDIC for a determination.
8. Confirm the bank's capital category — Map the capital classification (well-capitalized, adequately capitalized, undercapitalized) against permissible brokered deposit activity.
9. Apply rate restrictions if applicable — For adequately capitalized or undercapitalized banks, verify that deposit rates do not exceed the national rate plus 75 basis points.
10. Report in Call Reports — Classify and report brokered deposits in Schedule RC-E of the Consolidated Reports of Condition and Income (Call Report).
