SGOV vs high-yield savings accounts
Both are popular places to keep cash earning interest. The trade-off is SGOV’s state-tax advantage versus a savings account’s deposit insurance and instant access.

Short answer: A high-yield savings account (HYSA) is an insured bank deposit whose interest is taxed by your state. SGOV is an uninsured Treasury bill fund whose income is mostly exempt from state tax. If you live in a high-tax state and won’t need the money on a moment’s notice, SGOV can leave you with more after tax. If you value insurance and instant transfers, an HYSA is simpler.

The tax math
At SGOV’s current 3.76% SEC yield, someone in the 24% federal bracket with a 9.3% state tax keeps about 2.84% after tax, assuming 95.14% of the income is state-exempt. A savings account would need to pay about 4.26% to match. In a state with no income tax, the advantage disappears and you can compare the rates directly.
Access to your money
Savings account transfers are usually available the same or next business day without a trade. SGOV must be sold during market hours, and the cash settles one business day later. Both are fast compared with a CD or Treasury bill held to maturity.
Risk
A savings account balance cannot fall below what you deposited (up to insurance limits). SGOV’s price moves by cents around $100 and has stayed in a narrow range, but it is not guaranteed. SGOV’s credit risk is the US government’s; a savings account’s is the bank’s, covered by federal deposit insurance up to the limit.
