A closely watched case now pending before the Second Circuit could reshape how banks handle a category of fraud claims long understood — based on EFTA’s statutory framework and decades of case law — to sit outside Regulation E. Historically, courts and regulators treated wire transfers as outside Regulation E because they were viewed as bank‑to‑bank payment mechanisms governed by Article 4A rather than consumer‑facing electronic fund transfers.

At issue is whether certain consumer‑initiated online wire transfers may, in part, fall within the scope of the Electronic Fund Transfer Act (EFTA) and Regulation E. The case, brought by New York Attorney General Letitia James on behalf of The People of the State of New York, is fully briefed and submitted following oral argument earlier this month. A decision is expected later this year.

For banks, the significance is straightforward: if the Second Circuit affirms the district court’s reasoning, institutions may face Reg E–style obligations in scenarios where they have traditionally assumed those requirements do not apply.

The Issue

Regulation E generally applies to electronic fund transfers involving consumer accounts, while wire transfers have long been treated as outside its scope and governed instead by UCC Article 4A.

The appeal ultimately turns on how the “transaction” is defined.

New York and the consumer amici argue that a modern online wire transaction consists of multiple distinct “transfers” — a consumer‑initiated electronic debit or payment order submitted through an online or mobile banking interface, followed by a second, separate bank‑to‑bank wire transfer. Under that approach, only the interbank wire would fall outside Regulation E.

Appellant and the banking amici, by contrast, argue that the transaction must be viewed as a single, integrated wire transfer, such that the statutory exclusion applies to the entire flow of funds from start to finish.

That distinction is the question the Second Circuit must now resolve.

A Dividing Line in the Courts

Courts are not aligned on this issue.

Some have followed the district court’s reasoning and allowed claims to proceed under Regulation E where the consumer initiated the transfer through an online banking platform. Others, including courts in California, have rejected that approach, holding that consumer wire transfers remain governed exclusively by Article 4A.

That split is what makes the Second Circuit’s decision important. It is likely to become a reference point for how other courts, and plaintiffs, approach these cases going forward.

Why This Matters Now

Even before a decision is issued, the risk is already material.

Plaintiffs’ lawyers are increasingly focused on how transactions are initiated in online and mobile banking environments, not just how they are classified. Where a consumer accesses an account through a digital interface and initiates a transfer, particularly in fraud scenarios, there is a growing effort to bring those claims within Regulation E.

The disagreement also reflects a deeper tension between two longstanding legal frameworks. Regulation E is designed to protect consumers by allowing time to investigate disputed transactions and, where appropriate, to reverse or reimburse losses. UCC Article 4A, by contrast, prioritizes speed, certainty, and finality in wire transfers, limiting post‑payment disputes to preserve system stability.

The banking industry argues that applying Regulation E to any portion of a wire transaction would undermine those principles by introducing delay, reversibility, and expanded liability into a system designed to operate with near‑immediate finality.

That difference is significant because Regulation E carries very different consequences than Article 4A, including:

• defined investigation timelines,
• provisional credit requirements,
• error‑resolution obligations, and
• potential statutory damages and fee‑shifting.

In practical terms, the classification of a transaction can determine whether a dispute remains an operational issue or becomes litigation exposure.

What Banks Should Be Looking at Now?

Banks do not need to wait for the Second Circuit to act before assessing risk. The key question is not simply how transactions are labeled, but how they are handled and documented.

A few areas are worth reviewing:

1. Classification Protocols

How are online wire‑transfer disputes categorized at intake?
Are they automatically routed outside Regulation E without further analysis?

2. Customer‑Facing Communications

Do denial letters or explanations rely on broad statements that “wire transfers are not covered,” without addressing how the transaction was initiated?

3. Documentation and Evidence

Is the institution preserving clear records of:

• how the customer accessed the account,
• what authentication steps occurred, and
• how the transaction was initiated and processed?

4. Internal Assumptions

Perhaps most importantly, are teams relying on legacy assumptions that may no longer hold if courts continue to move in this direction?

Why the Outcome is Uncertain

The statutory question before the Second Circuit is not an easy one.

The text of EFTA defines ‘electronic fund transfers’ broadly, while its wire‑transfer exclusion speaks narrowly to transfers made by financial institutions over interbank wire services. At the same time, courts and regulators have long treated consumer wire transfers as governed by Article 4A, and Congress has never squarely addressed how EFTA should apply to modern consumer‑initiated online wire transactions.

How the court resolves the case may ultimately depend on whether it views New York’s component‑based analysis as a faithful application of statutory text—or as an artificial division that conflicts with the structure and purpose of Article 4A.

Looking Ahead

The Second Circuit’s decision will not necessarily resolve the issue nationwide, but it will carry weight—particularly in a jurisdiction where many financial institutions operate and where similar claims are likely to be filed.

If the court affirms the district court’s reasoning, banks should expect:

• increased scrutiny of online‑initiated transfers,
• expanded use of Regulation E in fraud litigation, and
• a shift in how disputes are framed at the outset.

If the court rejects that approach, the issue is unlikely to disappear. Plaintiffs will continue testing variations of the theory, and other circuits may be asked to weigh in.

Bottom Line

The question of whether Regulation E applies to certain online wire transfers is no longer settled. With a Second Circuit decision pending, banks should treat this as an active risk area — not a theoretical one.
