Federal officials have issued a rare demand for information about entities holding large amounts of Treasury notes.

The Treasury Department is calling for “large position reports” from individuals or companies that own more than $2 billion in 2% Treasury notes that are set to mature in September 2010 or 3-1/8% Treasury notes that are set to mature in September 2013.

Entities with large positions in those issues must file reports with the Federal Reserve Bank of New York by noon Nov. 14.

Federal agencies set up the large-position reporting program in 1995, to help Treasury Department officials and other securities regulators analyze apparent shortages and price distortions in the Treasury securities market.
