Before opening an account with 4-Week Treasury Bill, it helps to understand the category itself. The five short sections below explain how treasury bills work, who they suit, the main risks, where they fit in a plan, and the US regulatory rules.
T-bills are arguably the safest dollar-denominated investment in the world. They're sold at a discount and pay face value at maturity — the difference is your return.
T-bills mature in 4, 8, 13, 17, 26, or 52 weeks. You buy at a discount to face value and receive face value at maturity. Interest is exempt from state and local income tax.
Savers parking cash, building a Treasury ladder, or holding an emergency fund without giving up real yield to inflation.
Credit risk is effectively zero, but reinvestment risk is real: when rates fall, the next T-bill at maturity may yield much less. T-bills are not FDIC insured — they don't need to be.
T-bills work well for known near-term spending — a planned tax bill, a home down payment, the cash portion of an emergency fund in high-tax states. Beyond a year, the yield premium on intermediate Treasuries can be worth the small additional rate risk for money that won't be touched.
Issued by the US Treasury through weekly auctions and sold directly via TreasuryDirect.gov or through any broker. T-bill interest is exempt from state and local income tax — a meaningful boost for residents of California, New York and other high-tax states. They are full-faith-and-credit obligations of the federal government.
