Key Takeaways:
A disputed $4 million payment by JPMorgan Chase has galvanized the banking industry's push for changes to interbank settlement rules, with lenders arguing the current framework leaves them exposed to arbitrary financial penalties.
JPMorgan Chase deducted $4 million from a counterparty in what the industry has dubbed the "Salami Incident" — a reference to the practice of slicing a payment into small, unauthorized deductions. The move, which came to light in recent weeks, has triggered a backlash from other banks that say the current interbank payment framework lacks clear guardrails for such disputes.
"The existing rules were designed for a different era of banking, and they don't adequately address the kind of unilateral payment adjustments we're seeing," said James Okafor, a banking regulation analyst. "The industry needs a modernized framework that defines what constitutes a valid deduction and what doesn't."
The $4 million dispute centers on a payment that JPMorgan allegedly deducted without prior agreement from the receiving bank, according to people familiar with the matter. The incident has become a rallying point for lenders pushing for regulatory reforms, with several major institutions now calling on the Federal Reserve and the Clearing House to update the rules governing interbank settlements. The current framework, known as Regulation J and the Uniform Commercial Code Article 4A, has not undergone significant revision in more than a decade.
Industry Push for Reform
The backlash reflects broader frustration among banks over the lack of clarity in payment dispute resolution. Under current rules, a receiving bank can reverse or adjust a payment if it believes an error occurred, but the criteria for what constitutes an error remain loosely defined. This ambiguity, industry executives say, creates opportunities for what critics describe as "salami-slicing" — making multiple small deductions that individually may not trigger alarms but collectively add up to significant sums.
The American Bankers Association has begun drafting proposed rule changes that would require explicit counterparty consent before any payment adjustment exceeding $100,000, according to a person familiar with the discussions. The proposal would also mandate a 48-hour notification window and create a formal arbitration process for disputed deductions.
Regulatory Scrutiny Intensifies
The Federal Reserve has taken note of the industry's concerns. A Fed spokesperson said the central bank is "reviewing the current interbank payment framework and evaluating whether updates are warranted to ensure the integrity and efficiency of the payment system." The Fed last updated Regulation J in 2018, when it made technical changes to the check-collection and funds-transfer rules.
The incident comes at a time when the banking sector is already facing heightened regulatory scrutiny. The Fed's annual stress test results, released this week, showed that the 31 largest U.S. banks hold $1.1 trillion in capital — above regulatory minimums — but the tests also flagged operational risk as a growing concern across the industry.
For JPMorgan, the dispute adds to a series of regulatory headaches. The bank paid $348 million in penalties in 2024 related to trade surveillance failures and has been navigating heightened oversight of its internal controls. The $4 million at stake in the Salami Incident is negligible relative to JPMorgan's $4.1 trillion in assets, but the reputational fallout and the industry pushback it has triggered could prove far more costly.
If the industry succeeds in pushing through rule changes, banks could face higher compliance costs and more rigid payment processing requirements. The Clearing House, which operates the core U.S. payment system used by the largest banks, is expected to release a white paper on proposed rule changes by the end of the third quarter, setting the stage for what could be the most significant overhaul of interbank payment rules in a decade.
