A federal banking regulator called the Office of the Comptroller of the Currency—the agency that oversees national banks and reviews bank merger requests—had put out a new rule making it harder for bank mergers to sail through quickly, by getting rid of automatic approvals and simplified paperwork for certain deals. This resolution would cancel that rule, meaning the older, more streamlined merger review process would stay in place instead. Banks looking to merge would go back to the previous, faster approval options rather than facing the stricter review the canceled rule had set up.
