The American Bankers Association (ABA) has expressed opposition to Circle's application to establish a national trust bank in the United States. In a letter to the U.S. Office of the Comptroller of the Currency (OCC), the ABA also opposed similar applications from Fidelity Digital Assets, Protego Trust, and Ripple. The association argues that these companies have not provided sufficient information for public comment and views the applications as a potential backdoor to becoming national banks. The ABA has urged the OCC to delay the approval process until more information is disclosed about the applicants' business plans. The association seeks a comprehensive public review and stakeholder comment period before any decisions are made regarding these applications.
