The US Treasury has issued a proposed rule for determining fees to be paid by large financial institutions to cover the cost of the recently established financial-stability watchdog and other expenses related to the Dodd-Frank regulatory overhaul.

The Treasury plans to start collecting the semiannual fees in July 2012 from US bank holding companies with at least $50bn in total consolidated assets, foreign banks with at least that amount of assets in US operations, as well as nonbank institutions that fall under the supervision of the Federal Reserve, according to the proposal.
