US HB6556

Restricts use of concentration limit exceptions for failed bank mergers, requiring regulators to find "clear and convincing evidence" that the merger is necessary to prevent significant economic disruption or adverse effects on financial stability

Prohibits waiving deposit concentration limits (10% nationwide cap) unless the FDIC has received no qualified bids from institutions not subject to the concentration prohibition

Requires joint congressional reporting within 30 days when regulators waive concentration limits, including justification, alternative bids considered, and recommendations for improving competition in future bank resolutions

Defines "qualified bid" as one from a well-capitalized, well-managed institution where the resulting entity would also be well capitalized

Bars the FDIC from considering "bad faith bids" that would violate concentration limits when determining the least costly resolution option for the Deposit Insurance Fund
