H.R. 5921 would direct the Department of the Treasury to oppose International Monetary Fund assistance for Iran and transactions in Special Drawing Rights held by Iran. (Special Drawing Rights are an international reserve asset of the International Monetary Fund that are distributed to each member country.) Based on the cost of similar diplomatic efforts, CBO estimates that implementing those aspects of the bill would cost less than $500,000 over the 2024-2028 period. Any spending would be subject to the availability of appropriated funds.
