Open Banking for Community Banks: What Plaid, Fiserv, and Jack Henry Actually Support

The CFPB finalized its Section 1033 open banking rule in October 2024. A year later, a federal court in Kentucky barred the agency from enforcing it, and the case on appeal is on hold while the CFPB rewrites the rule. The agency opened that reconsideration with an advance notice in August 2025. As of October 2026, no revised proposal has been published, and none of the original compliance dates are being enforced.

The biggest reported change in the rewrite is fees. The 2024 rule barred banks from charging for data access. According to news reports cited by Ballard Spahr in June 2026, the CFPB intends to drop that outright ban and let data providers charge after a set number of free requests.

For community banks, the temptation is to treat open banking as a regulatory problem that has been postponed. That reading is wrong. Open banking is already running at community banks, through their cores, their digital banking platforms and their loan origination systems. The question is not whether it is coming. It is which of your workflows would benefit from it now.

What the Regulation Actually Says

Section 1033 of the Dodd-Frank Act gives consumers the right to access their financial data, subject to rules the CFPB writes. The 2024 rule would have required covered institutions to stand up a standardized developer interface for authorized third parties, on a schedule that started with the largest institutions.

Two things matter for community banks. First, the 2024 rule exempted depository institutions at or below $850 million in assets from the developer interface requirement. In October 2025, ICBA asked the CFPB to raise that exemption to every community bank with $10 billion or less in assets, and to let banks charge a reasonable fee for interface access. Other banking groups have opposed a broader exemption, so the final threshold is genuinely open.

Second, the federal pause is not the only front. New York lawmakers introduced bills in March 2026 that would require financial institutions to build a developer interface and bar them from charging for data access. Both were still in committee as of June.

The practical effect for most community banks right now: no rule requires you to build an API this year. But your customers are already sharing their data with fintechs through aggregators, and your vendors are already building for it.

What Plaid Actually Supports for Community Banks

Plaid says its network covers more than 12,000 financial institutions. The quality of those connections is not uniform. Where an institution has no API connection, aggregators have historically fallen back on credential-based access, which is less reliable and puts the customer's online banking password in a third party's hands.

In November 2025, Plaid expanded its Data Partner Dashboard to community banks and credit unions, letting them see and fix their own connection issues, monitor connection health and update how their brand appears in Plaid Link. It is a free, practical first step for any bank that has never looked at how its customers connect to fintech apps.

The most concrete lending deployment came on April 28, 2026, when MeridianLink announced an expanded partnership embedding Plaid Income in MeridianLink Consumer. A borrower connects a bank account, and income is verified from deposit data instead of uploaded pay stubs. The companies cite 80% conversion in lending flows, which is a vendor figure, and plan to add cash flow underwriting data later in 2026.

For a community lender already running MeridianLink Consumer, this is not a future capability. It is a configuration conversation.

What Fiserv and Jack Henry Actually Offer

The two largest community bank core providers approach open banking differently.

Fiserv. Open banking runs through Communicator Open, which Fiserv describes as a way for institutions on its account processing platforms to reach third-party fintech capabilities and pursue open finance strategies, delivered as RESTful APIs. Integration partners list support for Premier, Signature and Precision. Access is not automatic: PortX, an integration vendor, notes that banks typically need to re-license for API-first contracts and plan for integration work and middleware. If your bank is on Fiserv and has not discussed Communicator Open with its account team, start there.

Jack Henry. Jack Henry built its open banking connections early, through its Banno digital platform. In 2020 and 2021 it signed API-based data access agreements with Plaid, Finicity and Envestnet Yodlee, and in May 2021 it became the first core provider to join Akoya's data access network. Those connections replace credential-based screen scraping for Banno users with token-based access.

The practical difference: a bank on Jack Henry's digital platform likely already has API-based connections to the major aggregators. A bank on Fiserv may need to make a deliberate licensing and integration decision first.

Where Open Banking Adds Value Right Now

Three use cases are live at community banks today.

Income verification. Replacing manual document collection with deposit-based income verification cuts a step that can take days down to minutes, and removes a document request that borrowers often abandon over. The MeridianLink and Plaid integration is the clearest community lending example.

Account opening and funding. Instant account verification lets a new customer fund an account during opening, instead of waiting days for micro-deposits to post. For a bank trying to close the account opening gap with fintechs, that wait is a direct conversion cost.

Cash flow underwriting. Transaction data from a borrower's connected accounts can supplement traditional documentation for thin-file consumers and small businesses with revenue but little W-2 history. It is the use case most vendors, including MeridianLink, have named as next.

Why Not Wait for the Rule

The rewrite will settle the threshold, the fee question and the timeline. It will not change the direction. Customers already connect their accounts to apps, and lenders already verify income from bank data.

The banks waiting for the final rule will be building under a deadline.

For community banks, there is an advantage hiding in the delay. The friction left in open banking is mostly trust: customers deciding whether to connect an account, and to whom. Community banks have more of that than any fintech. The banks that build operational experience while the timelines are soft will move faster when they harden. The banks waiting for the final rule will be building under a deadline.
