How it works

TreasuryDirect.gov is the official retail portal of the US Department of the Treasury, operated by the Bureau of the Fiscal Service. When you open an account and purchase a security there, you are not going through a broker, a fund manager, or a fintech middleman. The security is held on the Treasury's own books in your name. There is no layer of private-company risk between you and the counterparty. The two products most relevant to a passive income system are Treasury bills (T-bills) and Series I savings bonds. T-bills are short-term debt instruments with maturities from 4 weeks to 52 weeks. You purchase them at a slight discount to their face value, and when they mature, you receive the full face value — the difference is your yield. The platform's auto-roll feature allows a T-bill to automatically reinvest at the next auction when it matures, meaning a T-bill ladder — multiple bills staggered at different maturities — can run near-passively once established. Series I savings bonds are inflation-indexed. Their composite rate has two components: a fixed rate that locks in for the 30-year life of the bond, and a variable inflation component that resets every May 1 and November 1. The current fixed component (0.90% for bonds purchased May 1 – October 31, 2026) is higher than it was during the 2020–2023 low-rate period, when fixed components were set at 0.00%. That fixed rate matters because it is the permanent baseline — the inflation kicker moves around it. ---

Where it fits in a system

TreasuryDirect does not replace any other platform in a well-built stack — it goes beneath them. Paired with Marcus (high-yield savings): TreasuryDirect handles the "untouchable floor" capital — the reserve you are not touching regardless of what happens elsewhere. Marcus handles the same-day-accessible emergency and near-term cash. They split the cash layer by liquidity tier, which is more precise than parking everything in a single HYSA and calling it done. Paired with Wealthfront or Betterment (robo-advisors): Robo-advisors handle long-hori

Real talk

Pros

• Zero fees of any kind — no account fee, no transaction commission, no management fee
• US government counterparty: structurally different risk profile from every other platform in the library
• Auto-roll on T-bills makes the capital reserve near-passive once configured
• State and local tax exemption on interest income
• I bond fixed rate (0.90% current) locks in for the life of the bond; that component does not move with rate environment changes

Cons

• Interface is utilitarian and dated; customer service is phone-only, no live chat
• T-bills in TreasuryDirect cannot be sold same-day — early exit requires a multi-day brokerage transfer process
• I bonds carry a mandatory 12-month lock and a 3-month interest penalty before year 5
• $10,000 per SSN per calendar year cap on I bonds limits scale
• Not a yield-maximization vehicle — in some rate environments, a well-run HYSA will post comparable or higher rates with more liquidity
