Treasury Department is calling in the big bond players.
The U.S. Department of the Treasury has issued a call for Large Position Reports from entities holding substantial positions in the 4-5/8% Treasury Bonds of February 2055, requiring reports from those whose holdings equal or exceed $6.9 billion as of June 2, 2025.
Why does this matter? These periodic reporting requirements help Treasury monitor market concentration in specific securities without presuming anything nefarious about large holders. “Treasury does not believe that large positions are inherently problematic, and there is no presumption of manipulative or illegal intent merely because an entity’s position is large enough to subject it to Treasury’s large position reporting regulations,” the department explains on its website.
Reporting Details and Deadlines
Entities holding the specified bonds must submit their reports before 12:00 P.M. Eastern Time on Monday, September 15, 2025. The specific security in question carries the CUSIP number 912810UG1 with a maturity date of February 15, 2055, and the reporting threshold has been set at $6.9 billion par value. Those falling below this threshold aren’t required to file a report.
Reports can be submitted through Treasury’s LPR webform, though the department has also made provisions for fax submissions in cases where entities encounter difficulties with the online system. “Large Position Reports may be submitted using Treasury’s LPR webform available at https://www.treasurydirect.gov/laws-and-regulations/gsa/lpr-form/,” the department noted in its announcement.

Evolution of Reporting Requirements
The reporting regime has undergone several refinements in recent years. In December 2014, Treasury amended its large position reporting rules to enhance the quality of information collected, allowing for better analysis of supply and demand dynamics in Treasury securities. Those changes became effective on March 10, 2015.
Later, a technical amendment published on October 18, 2018, provided the department with additional flexibility regarding how and where large position reports are filed. This update became effective the following month.
These periodic calls for large position reports help maintain transparency in one of the world’s most important markets without creating undue burdens on smaller market participants. It’s part of Treasury’s ongoing efforts to ensure the integrity and efficiency of government securities markets — a critical component of America’s financial infrastructure that affects everything from mortgage rates to retirement funds.
For bond market observers, these reporting requirements offer a glimpse into the sometimes opaque world of Treasury trading, where massive positions can occasionally move markets in unexpected ways.
