The U.S. Department of the Treasury’s large position rules (17 CFR 420) establish recordkeeping and reporting requirements for entities that control large positions in certain U.S. Treasury securities. Following a notice published in the Federal Register by the Treasury Department requesting information on positions above a large threshold amount (which must be at least $2 billion in size), persons who control a position in a particular U.S. Treasury security exceeding the specified large position threshold must file a report in the Treasury's reporting systems.
The rules are intended to improve the information available to the Treasury Department and other regulators regarding concentrations of control and ensure that regulators have the tools necessary to monitor the U.S. Treasury securities market. There is no presumption of manipulative or illegal intent on the part of the controlling entity merely because it is required to submit a large position report in response to these rules.
The material on this page provides information as to the obligation of holders of large positions in U.S. government securities to file reports as to those positions whenever the Treasury issues a special request. There is also a topic page that provides an overview of the regulation of Government Securities and Government Securities Dealers.
