Coupon securities only: notes, bonds, TIPS and floating rate notes; bills are not included. Each bar is what Treasury issued to the private sector of that security in the quarter, by settlement date: the auction amount less the Federal Reserve's SOMA add-ons. TIPS are at inflation-adjusted principal. Issuance only: coupon interest is not included.

'Net coupon issuance' is the quarter's issuance of all the coupon securities less the coupon securities that matured in the quarter and were not held by the Federal Reserve's SOMA portfolio (which rolls its maturities at auction outside the private offering), in $ billions. The line under the menu gives the issuance, the maturities and the net.

The current quarter mixes settled auctions, announced auctions at their offering sizes, and the Treasury Borrowing Advisory Committee's recommended and provisional sizes for auctions not yet announced; it is marked in the quarter menu and is a convention, not a forecast. Months follow settlement dates, which move to the next business day, so a quarter that ends on a weekend can hold a few settlements from the quarter before or after. History begins in the fourth quarter of 2003, when the Federal Reserve's holdings by security become available.
