The market for U.S. Treasury securities is the deepest and most liquid financial market in the world. As the national debt approaches historic levels relative to GDP, understanding the structural mechanics of how this debt is issued, priced, held, and sustained is critical to evaluating global financial stability.
Treasury Bills (T-Bills): Maturities from a few days to 52 weeks. Issued at a discount to face value — yield is the difference between purchase price and par. Treasury Notes (T-Notes): 2, 3, 5, 7, or 10-year maturities. Fixed semi-annual coupon. Treasury Bonds (T-Bonds): 20 or 30-year maturities. Semi-annual coupons. TIPS: Principal adjusted daily via CPI. Protects against inflation. Floating Rate Notes (FRNs): 2-year notes with weekly-adjusting coupons tied to 13-week T-Bill auction rates.
U.S. Treasuries are sold via Dutch auctions. Two bid types: Non-competitive bids (retail, capped at $10M, filled first at stop-out rate) and Competitive bids (ranked by yield from lowest to highest until the offering is filled). All successful bidders receive the stop-out yield.
The Primary Dealer Network (~24 elite institutions) is contractually obligated to participate in all auctions and bid for their reasonable share — ensuring the government can always clear debt sales.
Total ~$39.2 trillion: Intragovernmental Holdings (~31%, Social Security/Military trust funds), Debt Held by Public (~69%). Of public debt: Domestic holders include the Fed (SOMA), mutual funds, pension funds, commercial banks, state/local governments. Foreign holders (~26%) led by Japan and China — foreign central bank holdings have been declining as reserve diversification away from Treasuries accelerates.
Rising Debt Service: Annual gross interest expense now exceeds $1 trillion. Higher rates → higher refinancing costs → higher deficits → more debt issuance (self-reinforcing feedback loop).
Treasury Market Liquidity and the Basis Trade: Primary dealer balance sheets (constrained by post-2008 regulation) have grown slower than the Treasury market. Hedge funds fill the gap via the basis trade (long cash Treasuries via repo leverage, short futures). A repo market shock can force simultaneous liquidations — as seen in March 2020.
