Treasury Bills as a Cash Alternative
The plain answer
Section titled “The plain answer”A Treasury bill is short term debt issued by the United States government. It can be a useful place for cash you will not need until a known date, but it is not a bank account and does not provide the same immediate access. Use Treasury bills after you understand how they are bought, held, sold, and paid at maturity.
How it actually works
Section titled “How it actually works”When you buy a Treasury bill, you lend money to the federal government for a set period. Bills are commonly sold for less than the amount paid at maturity. The difference between the purchase price and maturity value produces your return.
You can buy bills when the Treasury issues them or through a brokerage that provides access to Treasury securities. Holding method matters. It affects how purchases are scheduled, where maturity payments go, and whether you can sell before maturity.
A bill held to maturity pays according to its terms. If you sell before maturity, its market price may be higher or lower than what you paid. Market price risk is the chance that changing interest rates and demand affect the sale price.
Treasury bills are backed by the credit of the United States government, but they are not FDIC or NCUA insured deposits. Their interest receives federal tax treatment that differs from ordinary bank interest and may receive favorable treatment from state and local income taxes. Check the current tax rules for your situation.
What this means for you
Section titled “What this means for you”Treasury bills can provide a competitive return and a known maturity date. The tradeoff is that buying, selling, and receiving proceeds involve more steps than moving money from savings. They are better suited to planned cash than to money needed immediately.
Before buying, check:
- The maturity date and how it matches your goal
- The expected yield and purchase price
- Where the maturity payment will be sent
- Whether your holding method allows an early sale
- Trading fees or account charges
- The possible sale price if you need money early
- Current federal, state, and local tax treatment
Keep an accessible bank balance for urgent needs. Use Treasury bills for a later layer of cash when the maturity schedule fits your plan.
Common mistakes
Section titled “Common mistakes”One mistake is treating a Treasury bill like an on demand savings account. Access before maturity may require a sale, and settlement can take time.
Another mistake is comparing a bill’s quoted yield with a savings APY without checking how each figure is calculated. Compare the amount you expect to receive over the same holding period after fees and taxes.
Do not assume government backing prevents a loss on an early sale. The payment at maturity and the market price before maturity are different questions.
