Parity Without an Answer: The FDIC Just Tied 3,185 State Banks to a Variable It Does Not Control

The FDIC's State Bank Parity proposal reached the Federal Register on September 22 at 91 FR 60018, and the trade-press read is that state banks won. That read is half right. The rule closes a gap that let the Illinois Attorney General argue a state bank with no Illinois branch must obey a law a national bank may ignore. What it does not do — what it expressly declines to do — is decide which laws those are.

Read the operative text. Revised § 331.3 provides that host state laws apply to an out-of-state state bank's branch, or to services it provides without a branch, "to the same extent as such State laws apply to a branch in the host State of, or any services provided in the host State by, an out-of-State national bank." That is a conditional. The FDIC wrote the conditional; it did not write the condition. Three sections later the proposal says so plainly: the rule "would not constitute a determination by the FDIC that any particular host State law is preempted by Federal law, though preemption of a host State law would be relevant in determining which State's law applies."

So a compliance officer at one of the 3,449 state banks counted in the proposal now has an answer to the wrong question. Whether Illinois law reaches your card program no longer depends on whether you branched into Illinois. It depends on whether Illinois law reaches a national bank — a question the OCC answers by rule and order, the Seventh Circuit is reviewing, and the Supreme Court has been asked three separate times this year to take up in a neighboring context. Comments close November 23, 2026.

How a branch became the wrong test

Section 24(j) of the FDI Act, 12 U.S.C. 1831a(j), arrived with the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (Pub. L. 103-328) and was sharpened by the 1997 amendments (Pub. L. 105-24, 111 Stat. 238). Its sponsor said the point was "to provide parity between State-chartered banks and national banks," a line the FDIC quotes from 143 Cong. Rec. H3088-89 (May 21, 1997) (statement of Rep. Marge Roukema). The drafting assumption was physical. Banks took deposits and made loans through branches, so branches were where a host state could discriminate. "Branch" is the word the statute uses.

The FDIC tried this once before. A 2005 proposal at 70 FR 60019 (Oct. 14, 2005) read § 24(j) to reach only state banks with interstate branches. It was never finalized. The agency now says that reading "does not reflect the broader purpose and structure of the statute," pointing out that since the first iPhone shipped in 2007, banks routinely serve customers in states where they hold no real estate and may hold none anywhere. On that history the FDIC is right, and the 2005 position was the weaker one. A rule that makes protection from host-state law turn on whether you lease a storefront is a rule that taxes digital delivery.

The trigger is Illinois. The Interchange Fee Prohibition Act, 815 Ill. Comp. Stat. 151/10-1 et seq., bars interchange on the tax and gratuity portions of a card transaction, restricts use of transaction data, and carries civil penalties of $1,000 per electronic payment transaction. Litigation followed. The OCC then moved twice on April 29, 2026: an interim final rule amending 12 CFR 7.4002 to confirm that national banks may charge non-interest fees including interchange, even when a third party sets them (91 FR 22989), and a separate interim final order concluding federal law preempts the IFPA (91 FR 23150). On June 1, 2026 the district court permanently enjoined enforcement against national banks, federal savings associations, card networks, and banks chartered outside Illinois "that are subject to Riegle-Neal, 12 U.S.C. § 1831a(j)(1)." Then the parties fought over who that last clause covers. Plaintiffs read § 24(j) broadly; the Illinois Attorney General read it to reach only branches "physically located" in Illinois. That gap is the rule's reason for existing.

The pointer problem

Here is the part the press release does not emphasize. Go to the OCC's own interim final rule and read new § 7.4002(e), the paragraph titled "State law": "The OCC applies preemption principles derived from the United States Constitution, as interpreted through judicial precedent, when determining whether State laws apply that purport to limit or prohibit charges and fees described in this section."

Stack the two instruments. The FDIC's rule points to national-bank treatment. National-bank treatment, on the OCC's own account, points to judicial precedent. Neither agency supplies a fixed answer, and the courts have not converged on one. The FDIC has built a conditional whose condition is litigated.

That matters more than it would have a decade ago, because the deference that once made OCC preemption pronouncements close to self-executing is gone. Dodd-Frank codified the Barnett Bank "prevent or significantly interfere" standard at 12 U.S.C. 25b and directed courts to weigh OCC preemption determinations under Skidmore rather than defer to them; Cuomo v. Clearing House Association, 557 U.S. 519 (2009), had already signaled the Court's unwillingness to accept the agency's expansive reading of its own authority. Loper Bright Enterprises v. Raimondo (2024) removed what remained. An OCC preemption order is now an argument addressed to a court, not an instruction binding one.

The escrow-interest fight shows what that looks like in practice, and it is the strongest available preview of where interchange is heading. The First and Second Circuits have split on whether the National Bank Act preempts state interest-on-escrow laws, the Ninth Circuit has gone its own way, and multiple petitions asking the Supreme Court to resolve it were pending as of late summer. Ten state attorneys general sued the OCC in the District of Oregon in August over its escrow preemption rule and determination — State of Oregon v. Office of the Comptroller of the Currency, No. 3:26-cv-01672-SI (D. Or., filed Aug. 11, 2026). Same statutory architecture, same agency, no settled answer after three years of litigation. Anyone assuming the interchange question resolves faster should say why.

Scope is the sleeper, not interchange

The economics here are small, and the FDIC's own numbers say so. Total transfers from the IFPA applying to state banks come to roughly $2.28 million a year, which the agency spreads across 3,185 affected institutions at about $713 per bank. One-time system costs are the larger figure at $308 million, but they concentrate in the handful of banks running payment systems in house: three acquirers fully in-house, five partially, with the remaining 103 outsourced. For a $600 million community bank that outsources cards, the IFPA exposure is $22,500 in upgrades and a rounding error in lost interchange.

So this rule is not about interchange revenue. Read § 24(j) as the FDIC quotes it: "[t]he laws of a host State, including laws regarding community reinvestment, consumer protection, fair lending, and establishment of intrastate branches." The rewritten § 331.3 carries all four categories forward and attaches them to the national-bank benchmark for services delivered without a branch. That is a much larger surface than card fees.

The FDIC knows it. Its second question for comment asks whether the rule "would affect settled applications of specific types of host State laws to out-of-State State banks in a way that may have unintended consequences," and requests examples. An agency does not ask that question about a rule it believes is narrow. A state bank lending into fifteen states from one charter now has a colorable argument that host-state consumer-protection requirements do not reach it wherever they would not reach a national bank. That argument will be tested by a state regulator or a private plaintiff, and the bank asserting it will be the test case.

To be fair, the competitive concern driving this is real, and the FDIC states it more bluntly in the small-entity analysis than anywhere else: the current uncertainty "may incentivize State-chartered banks to convert to Federal charters." That is the actual stake. Eleven other states have begun pursuing IFPA-style legislation. If each one reaches national banks differently than state banks, charter choice stops being about supervision and becomes about litigation exposure. CSBS President and CEO Brandon Milhorn made the same point supporting the proposal, arguing it would help ensure "charter choice is driven by business needs and supervisory quality rather than outdated regulatory distinctions." Preserving a viable state charter is a legitimate objective, and on that score the proposal is well aimed.

It just does not deliver certainty. It delivers a cross-reference.

What to watch

Comments close November 23, 2026. The rule text set the window at sixty days from publication, which lands on a Saturday; the published deadline is the following Monday. Three things belong in a comment letter. First, ask the FDIC to say how a bank determines, in real time and without litigating, whether a given host-state law applies to a national bank; a safe harbor keyed to a published OCC determination would be worth more than the rule as drafted. Second, press the scope question the agency itself raised, with named statutes in fair lending and state UDAP. Third, note that § 27 of the FDI Act, 12 U.S.C. 1831d, is untouched by design, and that the rule's silence on the interaction between rate exportation and non-rate terms will generate exactly the confusion the proposal says it is preventing.

The IFPA's effective date has slipped to July 1, 2027, which gives everyone a full compliance cycle. Use it. The Seventh Circuit appeal and the pending escrow-interest petitions will both move before then. Either could reset the benchmark this rule points at.

Bottom line

The FDIC has fixed a drafting problem worth fixing: after this rule, a state bank no longer has to open a branch it does not want in order to be treated like a national bank it is not. But institutions should not mistake a cross-reference for an answer. The rule makes state-bank compliance derivative of national-bank preemption at the precise moment national-bank preemption is least settled — contested across three circuits, litigated by ten state attorneys general, and entitled to no judicial deference after Loper Bright. Boards briefed that this proposal removes legal risk are being briefed wrong. It relocates the risk to a docket the bank does not control.
