Money sitting in a single bank account above $250,000 has always carried some exposure the standard FDIC insurance limit doesn’t cover on its own. Banks have spent years building networks that split large deposits across many banks to close that gap without the depositor lifting a finger, and a rule change adopted at the end of August makes those networks meaningfully more useful for the banks that run them.
What the FDIC Actually Approved
On August 27, 2026, the FDIC’s Board of Directors approved an interim final rule implementing section 902 of the 21st Century ROAD to Housing Act. The rule raises the amount of reciprocal deposits a bank acting as an “agent institution” can exclude from being treated as brokered deposits, replacing the prior flat limit with a new tiered, liability-based calculation that can reach as high as $30 billion. It also broadens the legal definition of “agent institution” itself and clarifies several operational details of how the reciprocal-deposit framework functions.
Two things distinguish this from a routine bank-industry announcement, according to the FDIC’s own press release. First, it is an interim final rule rather than a proposal — it reflects a change the FDIC has already adopted, not one still under internal debate. Second, and just as important, the release states that “comments on the rule are due within 30 days after the date of publication in the Federal Register,” meaning the agency is still formally taking public feedback even as the rule already governs. That combination — adopted now, comment period still running — is exactly what “interim final rule” is designed to convey, and nothing in the FDIC’s release suggests this version is closed to further revision.

How a Reciprocal Deposit Network Gets Past $250,000
The FDIC’s standard deposit insurance limit is $250,000 per depositor, per bank, per ownership category, a figure laid out in the agency’s own Deposit Insurance At A Glance guidance. A reciprocal deposit network gets a depositor past that ceiling without the depositor personally opening accounts at multiple banks. As the National Credit Union Administration’s plain-English explainer describes it, a depositor places a large sum with one bank, that bank places portions of it into a network of other participating banks in amounts that stay under $250,000 at each one, and in exchange it receives an equivalent amount of deposits placed by other banks in the same network — so the total sitting on the original bank’s balance sheet doesn’t change, but the depositor’s funds are now insured in pieces across many institutions instead of exposed at one.
Regulators have historically treated large reciprocal-deposit arrangements with some caution because, structurally, they resemble brokered deposits — funds a bank attracts through a third party rather than through its own direct customer relationships — which regulators have watched closely since the savings-and-loan failures of the 1980s were partly funded by that kind of hot, flighty money. The exclusion this rule expands is the carve-out that lets a bank treat qualifying reciprocal deposits as ordinary deposits instead, avoiding the extra scrutiny and cost that comes with a brokered-deposit label, as long as the bank stays under whatever the current excludable cap is.
Why the Cap Went From a Flat Number to a Tiered One
The move from a single fixed exclusion limit to a tiered, liability-based calculation means the maximum amount of reciprocal deposits a bank can exclude now scales with the size of that specific bank, up to the new $30 billion ceiling, rather than applying the same dollar cap uniformly regardless of institution size. For a mid-size or regional bank that had bumped up against the old flat limit while building out deposit relationships with larger business or municipal customers, a size-scaled cap functions less like a wholesale deregulation and more like an adjustment meant to keep the exclusion relevant as reciprocal-deposit networks and the banks using them have grown.
None of this changes what an individual depositor’s own insurance coverage looks like. A customer using a reciprocal deposit network to insure, say, $2 million is still covered in $250,000 increments across the participating banks in that network, exactly as before — what changed is how much of that arrangement the agent bank itself can carry on its books without it counting against brokered-deposit limits that trigger additional regulatory requirements.
What Comes Next
Because the rule is interim rather than a closed final rule, its current form is not necessarily its last. The 30-day comment window that opens once the rule is published in the Federal Register gives banks, credit unions, and other stakeholders a formal channel to flag problems with the new tiered calculation or the broadened “agent institution” definition before the FDIC considers any further adjustments. Anyone tracking this rule for its eventual final language, rather than its current interim status, should watch for a follow-up Federal Register notice rather than assume the version adopted August 27 is the last word.
