Vanguard has 3 funds that can replace your savings account. 1....

1. $VUSXX
2. $VBIL
3. $VMSXX
Here are all the details:
This is a fund that invests in short-term U.S. government securities (like Treasury Bills)
It tries to maintain a stable $1.00 NAV and offers a competitive yield, making it a popular cash alternative.
Note: Other custodians, like Fidelity or Schwab, have their own versions of Treasury Money Market Funds that you can get.
However, it's not FDIC-insured, but it is backed by the U.S. Treasury.
2. $VBIL
$VBIL is Vanguard's newly launched 0-3 Month Treasury Bill ETF. It invests exclusively in U.S. Treasury bills (0–3 months).
The yield is not posted yet, as it's a new fund, but it's probably around the 4.3% range as well.
Since the fund holds T-bills, it will be state/local tax-exempt.
If you are in the 37% tax bracket, it might actually make more sense to hold $VMSXX for your short-term savings.
It's Vanguard's Municipal Money Market Fund, a tax-exempt fund that invests in municipal securities
The yield is 2.71%, but it is exempt on a federal level.
Here's how you can do the calculation:
$VUSXX after-tax yield is 4.27% * (1 - 40.8%) = 2.53%.
$VMSXX after-tax yield is 2.71% * (1 - 5%) = 2.57%.
Tax-exempt interest could also make a difference on your other tax credits/deductions.
However, municipal funds are typically more risky than Treasury funds.
1. Yields comparable to HYSAs without having to switch HYSAs every year.
2. Tax benefits (either state tax-exempt or federal).
But, they aren't FDIC insured like your bank.
