A new Periodic Transaction Report filed with the U.S. House of Representatives shows that Rep. Doris O. Matsui, who represents California’s 7th District, disclosed a purchase made by her spouse involving a U.S. Treasury Note due August 31, 2030. The transaction, dated December 15, 2025, falls into the disclosure category of over $1,000,000, the highest reporting bracket available under the STOCK Act’s tiered system.
For readers who follow congressional stock trading tracking sites, this filing is a straightforward one: a fixed-income instrument backed by the federal government, purchased in a size large enough to require the top-tier disclosure range. Treasury Notes like this one are not equity positions in a company; they represent a loan to the U.S. government with a set maturity date, in this case just under five years out from the transaction.
What the Disclosure Actually Says
Under the STOCK Act, members of Congress and their spouses must report transactions in stocks, bonds, and other covered securities within 45 days of execution. This report identifies the asset only as a U.S. Treasury Note due 8/31/2030, tracked internally by some data platforms under the shorthand ticker GS for government security classification purposes. The filing lists the transaction type as a purchase and the filer as the member’s spouse, not Rep. Matsui herself.
Because the amount range disclosed is over $1,000,000, the exact dollar figure is not made public. STOCK Act reporting rules only require a bracketed range, so outside observers can know the transaction exceeded the seven-figure threshold but cannot determine the precise size beyond that.
Why This Shows Up as a ‘Congress Buy’ Signal
Sites that aggregate these filings, including trackers popular with readers searching for capitol trades tracker data or comparing patterns similar to well-known figures like Pelosi’s investment returns, classify transactions like this one simply as a purchase event. In this case, the classification is congress buy, reflecting that new capital was moved into the asset rather than withdrawn from it.
It is worth noting that Treasury securities are among the most commonly disclosed assets in these filings across both parties, often used as a place to park significant capital in a low-risk, interest-bearing instrument. Nothing in the disclosure indicates any connection between this purchase and Rep. Matsui’s legislative work, and STOCK Act filings exist precisely so that these transactions are made a matter of public record rather than kept private.
