Bank Service Company Examination Coordination Act of 2023

This bill amends the Bank Service Company Act to improve coordination between federal and state banking regulators. It requires federal examiners to notify and coordinate with state banking agencies when examining bank service companies where a state bank is a shareholder or member, aiming to avoid duplicate work and streamline oversight. The law specifies that state agencies can only access information they already have authority to obtain under state law, and it updates definitions to consistently include "State banking agency" throughout the law. This directly affects federal banking agencies (like the OCC), state banking regulators, and the bank service companies they oversee. The changes focus on procedural coordination without altering the core examination requirements for these service providers.
