FDIC Reciprocal Deposits Rule: The New $30 Billion Cap Is Not a Liquidity Free Pass

TL;DR

• The FDIC reciprocal deposits rule implements a tiered general cap that can reach $30 billion, replacing the old limit of the lesser of $5 billion or 20% of liabilities.
• A well-capitalized bank with a CAMELS composite rating of 1, 2, or 3 can now qualify under the first “agent institution” prong. CAMELS 3 is the meaningful expansion.
• The law changed on July 11, 2026. The FDIC’s interim final rule becomes effective upon Federal Register publication, and September 30 Call Report instructions will reflect the change.
• Treasury can use the added capacity, but Risk should separately cap network, channel, and uninsured-depositor concentration. “Not brokered” is a reporting classification, not a liquidity conclusion.

A bank with $25 billion in liabilities can now hold up to $8.6 billion of reciprocal deposits within the general statutory exception—more than the old $5 billion ceiling.

That is the headline in the FDIC reciprocal deposits rule released August 27, 2026. The rule implements section 902 of the 21st Century ROAD to Housing Act, which took effect July 11. It also opens the first “agent institution” eligibility route to well-capitalized banks with a CAMELS composite rating of 3, not only institutions rated 1 or 2.

For Treasury, that creates usable funding capacity. For Risk and Finance, it creates an immediate classification, concentration, and reporting job.

The easy mistake is to treat the expanded exception as proof that reciprocal deposits are stable. It is not. The legal question is whether deposits fall outside the brokered-deposit classification under section 29 of the Federal Deposit Insurance Act. The liquidity question is how fast deposits sourced through the same placement network can move during stress. Those questions belong in the same dashboard, but they do not have the same answer.

What the FDIC reciprocal deposits rule changes

A reciprocal deposit arrangement generally works like this: Bank A places a customer’s funds through a deposit placement network at other insured banks in amounts within the deposit insurance limit. In return, Bank A receives the same aggregate amount from other network members. The customer gets access to pass-through deposit insurance across participating banks while Bank A can retain the relationship and receive replacement funding.

The FDIC’s brokered-deposit resource center explains the wider framework: section 29 restricts less-than-well-capitalized institutions from accepting brokered deposits, while adequately capitalized institutions may request a waiver. Reciprocal deposits receive a limited exception when the bank is an “agent institution” and remains within its applicable cap.

The 2026 law and interim final rule change two central parts of that exception.

The operative regulation is 12 CFR 337.6. The FDIC’s interim final rule, RIN 3064-AG32, provides the new formula and the agency’s implementation details.

How the new $30 billion reciprocal deposit cap works

The new general cap is not simply “$30 billion for everyone.” It is a marginal, tiered calculation based on total liabilities:

The FDIC’s own example is the cleanest way to test the formula. For an institution with $25 billion in total liabilities:

• 50% of the first $1 billion = $0.5 billion
• 40% of the next $9 billion = $3.6 billion
• 30% of the remaining $15 billion = $4.5 billion
• General cap = $8.6 billion

The FDIC will calculate the cap using liabilities reported in the bank’s Call Report. That makes the cap a reporting-data control, not a number Treasury should maintain in a standalone spreadsheet without reconciliation.

Put the calculation under change control

Finance or Regulatory Reporting should own the source liabilities. Treasury should own daily utilization. Second-line Liquidity Risk should challenge both the calculation and the operating buffer.

A workable control record should capture:

Do not set the internal operating limit equal to 100% of the statutory cap by default. A cap breach can change regulatory classification. An internal buffer gives Treasury room for timing differences, late files, corrections, liability growth, and network rebalancing.

A starter approach is to set an internal warning threshold below the statutory cap, then calibrate it using the last three to six months of daily reciprocal-deposit volatility and reporting adjustments. The percentage is an institution-specific judgment. The evidence should show why the buffer covers observed movement and operational error—not that someone selected a round number.

CAMELS 3 eligibility creates the biggest operational change

Under the first agent-institution prong, a bank now qualifies if it is well capitalized and its most recent CAMELS composite rating is 1, 2, or 3. Previously, the FDIC interpreted “outstanding or good” as CAMELS 1 or 2.

That means some well-capitalized CAMELS 3 institutions can use the general reciprocal-deposit exception without relying on another eligibility route. The effective rating date is the date of written notification from the primary federal regulator or state authority. A capital-category change follows the effective date under prompt-corrective-action rules. A brokered-deposit waiver becomes operative when the bank receives written FDIC approval.

This is where ownership gets messy. The supervisory rating is confidential. Treasury still needs an unambiguous signal about whether the bank may use the first prong and which cap applies, but it may not need access to the examination report itself.

The clean operating model is a controlled eligibility attestation:

1. Legal or the Regulatory Affairs function receives and restricts supervisory information.
2. The CFO and CRO approve an attestation stating the eligible route, effective date, applicable cap, and any conditions—without unnecessarily circulating the rating package.
3. Treasury configures the operating limit from that attestation.
4. Regulatory Reporting retains the cap calculation and Call Report treatment.
5. Internal Audit tests the handoff, access control, and evidence trail rather than republishing confidential supervisory information in workpapers.

A rating change, capital-category change, waiver decision, or unexpected increase in reciprocal deposits should automatically trigger revalidation. Calendar-based annual review is too slow for an eligibility condition that can change when written notice arrives.

The special cap still has teeth

The general cap gets the headline. The special cap is where a bank can create a classification problem by continuing normal network activity after its eligibility changes.

The FDIC’s rule clarifies that an institution subject to the special cap may continue holding reciprocal deposits it received before the status change, even if that amount exceeds the special cap. But “receiving” additional reciprocal deposits above the special cap can cause the institution to stop qualifying as an agent institution, with all reciprocal deposits then reported as brokered.

For nonmaturity reciprocal deposits, a network operator can change underlying depositors or rebalance amounts without the bank receiving more in aggregate. That network-level movement does not by itself mean the bank received new reciprocal deposits. The danger is the bank placing additional covered deposits while already holding reciprocal deposits above the special cap. The FDIC says that activity can constitute receiving deposits over the cap and end agent-institution status.

Treasury needs a freeze control, not a memo:

• Tag the current eligibility route and cap in the placement-network workflow.
• If the bank becomes subject to the special cap and current balances exceed it, block new covered-deposit placements.
• Require Treasury, Legal, and Regulatory Reporting approval before the block is removed.
• Reconcile attempted placements to network confirmations so a rejected or manually overridden transaction cannot disappear from the audit trail.
• Test the block at least annually and after any network-platform change.

The human failure mode is predictable: Treasury sees that balances can remain in place and assumes ordinary placement activity can continue. The rule separates holding from receiving. The control has to do the same.

Call Report work starts now

The FDIC says the FFIEC will issue supplemental instructions for the September 30, 2026 Call Report period and expects the regular instructions to conform by December 31, 2026. No new line item is expected.

That does not make implementation automatic. Existing fields must reflect the new law correctly. The rule specifically discusses Schedule RC-E Memorandum item 1.g for total reciprocal deposits and Schedule RC-O item 9 for brokered reciprocal deposits. The FDIC anticipates making RC-O item 9 confidential because, when paired with public reciprocal-deposit data, it may reveal nonpublic supervisory information about an institution’s eligibility.

Regulatory Reporting should assemble a September evidence pack containing:

• the quarter-end liability source and reconciliation;
• the tiered cap calculation;
• the eligibility attestation and effective date;
• total reciprocal deposits by product and maturity type;
• amounts treated as brokered reciprocal deposits;
• network-to-core-to-general-ledger reconciliation;
• review evidence for manual adjustments;
• a sign-off from Treasury, Regulatory Reporting, and second-line Risk.

If an examiner asks how the bank classified reciprocal deposits, the answer should be reproducible from those artifacts. “The network vendor told us the number” is not a regulatory-reporting control.

Why “not brokered” does not mean “stable funding”

The FDIC estimates that the statutory change could reduce aggregate annual assessment revenue by about $45.8 million, based on March 31, 2026 data, because more reciprocal deposits may fall outside brokered treatment. The agency also expects the change to increase reciprocal-deposit use, including among institutions that had not previously participated in these networks.

That regulatory treatment can improve economics. It does not erase behavioral risk.

A deposit network can distribute funds across many banks and underlying depositors. Operationally, however, the bank may still depend on one network, one integration, one pricing strategy, or one class of rate-sensitive customers. Classification diversification is not necessarily funding-source diversification.

Connect the new capacity to the existing deposit concentration KRI framework. At minimum, ALCO should see:

• reciprocal deposits as a percentage of total deposits;
• deposits sourced through the largest placement network as a percentage of total funding;
• insured versus uninsured funding composition;
• average rate paid versus comparable relationship deposits;
• 7-, 30-, and 90-day maturity or withdrawal exposure;
• reciprocal-deposit runoff under idiosyncratic and market-wide stress;
• utilization against both the statutory cap and the lower internal limit.

Then connect those metrics to the contingency funding plan triggers and liquidity stress-testing scenarios. A larger legal capacity should appear in stress testing as a larger possible outflow or repricing exposure—not only as additional available funding.

A 30/60/90-day implementation plan

First 30 days: prove the classification

Regulatory Reporting should calculate the cap from the latest filed Call Report and retain the source-to-form reconciliation. Legal or Regulatory Affairs should document the agent-institution eligibility route and effective date. Treasury should inventory every reciprocal-deposit network, product, maturity structure, and current balance.

Deliverable: one approved eligibility-and-cap memo, with source reports attached and no confidential supervisory details distributed beyond need-to-know recipients.

By day 60: put the cap into operations

Treasury Operations should configure warning and hard-stop thresholds. Technology or the network-platform owner should implement the special-cap placement freeze. Finance should dry-run the September Call Report classification. Liquidity Risk should add reciprocal-deposit utilization, network concentration, and runoff metrics to the ALCO pack.

Deliverable: a completed dry run showing that network reports reconcile to the core, general ledger, cap calculation, and Call Report fields.

By day 90: test failure, not just normal processing

Second-line Risk should run a scenario in which the bank’s eligibility changes while reciprocal deposits exceed the special cap. Internal Audit or independent testing should attempt an unauthorized new placement and confirm the block, escalation, and audit trail work. ALCO should approve an internal operating limit and stress assumptions.

Deliverable: test evidence showing who receives the alert, how quickly placement activity stops, how deposits are reclassified, and which committee receives the breach report.

The practitioner takeaway

The FDIC reciprocal deposits rule gives banks more room. It also makes weak handoffs more expensive.

The cap starts with Call Report liabilities. Eligibility depends on supervisory and capital information. Daily utilization sits with Treasury. Classification belongs to Regulatory Reporting. Concentration and stress assumptions belong to Risk and ALCO. If those teams each maintain their own version, the bank can be under its cap in one file and over it in another.

Start with one governed calculation and one controlled eligibility signal. Then build the funding decision around actual liquidity behavior. The new law can change whether a reciprocal deposit is labeled brokered. It cannot make network concentration disappear.

For teams rebuilding the liquidity, concentration, and capital-control evidence behind that decision, the Financial Risk Management Kit provides the working dashboards and committee reporting structure without turning the rule into another orphaned memo.
