H.R. 3948 would amend the Bank Holding Company Act of 1956 to require Global Systemically Important Banks (GSIBs) to submit an annual report to the Board of Governors of the Federal Reserve containing a description of the activities and goals of the company. It would also require the Board of Governors to post those reports on its website. CBO estimates that enacting H.R. 3948 would decrease revenues by $3 million over the 2021-2031 period.
