If you’re looking for a safe place to park your cash, certificates of deposit (CDs) and Treasury bills (T-bills) are two solid options. Both offer decent yields with practically zero risk, but they work in different ways.
So, which one is the better choice right now? Let’s look at the pros and cons of each.
How long does your money stay locked in?
CDs and T-bills both have fixed terms, but they offer different levels of flexibility.
- CDs: Terms typically range from 3 months to 5 years (although it’s possible to find terms that are both shorter and longer than this). At the moment, shorter-term CDs generally have higher interest rates.
- T-bills: Offered in short-term maturities of 4, 8, 13, 17, 26, and 52 weeks. Rates are very similar across all terms, though 52-week T-bills currently have the lowest yields.
If you want to get your money back in under three months, T-bills may be the better choice. If you’re OK with locking it up for longer, CDs might work for you.

Which pays more?
CDs and T-bills currently offer similar interest rates, though it varies based on the term.
- CDs: Right now, most CDs yield about 4.00%. Some CDs with terms of 14 months or less pay up to 4.50%.
- T-bills: Recent yields have been between 4.12% and 4.32%, depending on the maturity date.
Which is easier to buy?
CDs and T-bills are both easy to purchase, but the process is different.
- CDs: You can invest in CDs through banks, credit unions, and brokerages. Once you invest, your money is generally locked in until maturity unless you pay an early-withdrawal penalty.
- T-bills: You can buy T-bills directly from the U.S. Treasury at TreasuryDirect.gov or through a brokerage account.
Tie-breaker: Which is easier to sell?
Most people who buy CDs and T-bills hold them until they mature, then collect the interest. However, both can also be sold if they’re held in a brokerage account. There’s more investor demand for T-bills, so it’s easier to sell T-bills quickly and at the price you want.

How much will you owe in taxes?
The interest you earn will generally be taxed unless your investments are held in a tax-advantaged account, like an individual retirement account (IRA).
- CDs: Interest earned is subject to federal, state, and local income taxes.
- T-bills: Interest is exempt from state and local taxes but still taxed at the federal level.
If you live in a high-tax state, T-bills may have an edge because they avoid state income taxes.
Which one should you choose?
- Pick CDs if: You want the highest interest rate available and plan to keep the CD until it matures.
- Pick T-bills if: You want a shorter term than CDs offer, live in a high-tax state, or plan to sell your investments on the secondary market.
There’s no one-size-fits all answer, so consider all the above and shop around for the best rates before you invest in either CDs or T-bills.
