FDIC would clear de minimis bank mergers in five business days without public comment

The concentration test decides which deals get to use the fast lane, and the FDIC is widening the market it measures. Staff at the board meeting said the recalculated index would "continue to incorporate the deposits of all banks, but would now include a representative share of deposits of thrifts, shares of credit unions and banks and thrifts centrally booked deposits to more holistically consider the financial services market" ^[7]. The Herfindahl-Hirschman Index sums the square of each participant's share of the measured market, so adding credit union and thrift deposits to the total cuts every bank's share and cuts the index with it ^[4]. Two banks in the same county could pass a test they failed before without changing a term of the deal. Transactions that miss the safe harbor would be argued on other pro-competitive factors, and the FDIC flagged rural areas in particular ^[9]. According to American Banker's account of the meeting, the proposal's HHI thresholds and the size test for de minimis were not specified.

Now the clock. Five business days spans no more than seven calendar days. That puts the fast lane at roughly a thirteenth of the 90-day standard period and at least 38 times shorter than the 270-day outside limit ^[5][1][2]. De minimis filings would also skip the public comment period ^[3].

Chairman Travis Hill has argued that the changes account for the way consumers reach financial products through digital channels and from nonbank providers ^[18]. "Not all banks operate nationwide, but all banks compete with banks and non-banks who do," Hill said at the meeting ^[15].

The package reverses a bank merger policy the same agency drafted in 2024, when Hill was its vice chair ^[14][19]. Both proposals now sit in a 60-day comment window ^[13]. Comptroller of the Currency Jonathan Gould recused himself from the state-bank parity proposal, which carried on the two remaining participating votes ^[11][3]. On the merger rule he voted yes and pushed for more. "I'm particularly interested in whether there are opportunities for further reforms by the FDIC or on an interagency basis that are consistent with the requirements of the Bank Merger Act," Gould said ^[17].

The FDIC sets the de minimis bar low, and the five-day lane mostly clears internal reorganizations, whose comment periods are being shortened anyway ^[4]. Or the bar is generous, the widened deposit market pulls most community bank pairs inside the safe harbor, and months come out of small-bank consolidation. Or a later board rewrites it again, and acquirers keep underwriting the old timeline, since the proposal can still be rewritten before it takes effect.

I would put more weight on the market definition than on the five-day headline. A shorter clock helps deals that were going to be approved; a bigger measured market changes which deals are approvable at all ^[7][8]. The evidence against that view would be safe harbor thresholds set tight enough that counting thrifts and credit unions moves no bank pair across a line, in which case the whole package is a change to the filing calendar.
