The latest Treasury bill auction came in with yields that should make anyone parking cash in a big-bank savings account sit up and pay attention.
Short-term T-bills are still paying meaningfully more than the national average savings rate, and the gap is wide enough to matter on real money.
At the most recent auction, three-month bills cleared around 4.3%, while six-month bills landed in a similar range.
Compare that to the roughly 0.4% the average savings account pays, according to FDIC data, and the difference stops being academic.
On $10,000, that spread is worth hundreds of dollars a year.
Treasury bills are short-term IOUs sold by the federal government in $100 increments, maturing in four weeks to a year.
When the Fed holds rates high, T-bill yields stay elevated, and banks have little incentive to pass those rates along to everyday depositors.
You can't buy T-bills at your corner bank branch, and many people assume they need a broker or a minimum balance.
In reality, anyone can buy them commission-free through TreasuryDirect, the government's own portal, or through most major brokerage accounts.
There's also a tax wrinkle worth knowing.
T-bill interest is exempt from state and local income tax, which makes the effective yield higher than a comparable CD or savings account if you live in a state with income tax.
That detail alone can swing the decision for savers in places like California or New York.
You can sell T-bills on the secondary market before maturity, but prices move with rates, so you could get back slightly less than you put in if you sell early.
Hold to maturity and the math is simple and predictable.
If you want in, the next auction dates are posted on TreasuryDirect, and you can set up automatic reinvestment so maturing bills roll into new ones without you lifting a finger.
Just don't expect the same yield forever.
These rates track the Fed, and they can fall as quickly as they rose.
One more thing: don't chase this with money you might need this month.
T-bills work best for cash you can genuinely set aside for the full term, whether that's four weeks or six months.
Emergency funds you might tap tomorrow are better off somewhere instantly accessible.
The bottom line is that the gap between what banks pay and what the government pays is still wide enough to be worth a look, and setting up an account takes about as long as opening a new streaming subscription. **Our take:** Treasury bills aren't glamorous, and nobody's going to brag about them at a cookout.
Final Thoughts
But when the spread over a typical savings account is this large, doing nothing is a choice with a real cost attached.
