No on both counts. SGOV is an exchange-traded fund, the iShares 0-3 Month Treasury Bond ETF. FDIC insurance covers bank deposits, and SGOV is not one. It is also not a money market fund, because it trades on an exchange at a moving price instead of holding $1.00. What stands behind it is its holdings: US Treasury bills maturing within three months.
SGOV gets filed mentally next to savings accounts and money market funds because people use it for the same job, parking cash. The three are built differently, and the differences decide what can go wrong.
Three things that do the same job differently
| Bank savings | Money market fund | SGOV | |
|---|---|---|---|
| What it is | A deposit | A mutual fund | An ETF |
| FDIC insured | Yes, to $250,000 | No | No |
| Price | Fixed | Targets $1.00 | Moves daily |
| How you get in and out | Transfer | Once a day at the fund's price | Buy and sell on the exchange |
| Fee | None stated | Often 0.10% to 0.45% | 0.09% |
What actually backs SGOV
SGOV holds US Treasury bills with three months or less to maturity. A Treasury bill is a direct obligation of the US government, which is the reason short-term Treasuries are the benchmark other "safe" assets get measured against. FDIC insurance is itself a promise backed by the same government. So the question "is it insured" slightly misses the point: SGOV does not have insurance on top of its assets because the assets are the government's own debt.
That is a statement about credit risk. It is not a guarantee about the share price on any given day, and it does not make SGOV a deposit.
Why the price moves, and why that is fine
A money market fund works to keep its share price at $1.00 and pays you interest separately. SGOV does it the other way around. Interest builds up inside the fund, so the share price creeps up a little each day, then drops by the amount of the distribution when it pays out each month. The sawtooth on the chart is the interest, not a loss.
Because the bills mature within three months, changes in interest rates barely move the price. Outside that monthly payout pattern, day-to-day moves have been tiny. You also pay a bid-ask spread when you trade, usually a penny a share.

The protection you do have
- SIPC. If your brokerage fails, SIPC covers up to $500,000 per customer, including $250,000 in cash, to get your securities back to you. It protects against the firm failing, not against a price change.
- Segregated assets. The fund's Treasury bills are held by a custodian, separate from BlackRock's own balance sheet.
- The state-tax treatment. Not a safety feature, but it is the practical edge: most of SGOV's income is exempt from state income tax, which a bank account's interest is not. See is SGOV exempt from state tax.
"Is it FDIC insured" is the right instinct pointed at the wrong test. For cash you cannot afford to see move by a single cent, or that you need at 9 p.m. on a Sunday, a bank account is the right tool and no fund replaces it. For cash you are holding for months, SGOV's lack of FDIC insurance is the least interesting thing about it. The fee, the state-tax treatment, and how it compares with a money market fund or a high-yield savings account are what change the number you end up with.
SGOV, FDIC insurance, and money market funds
- SGOV is not FDIC insured. FDIC covers bank deposits, and SGOV is an ETF.
- SGOV is not a money market fund. It trades on an exchange and its price moves; it does not target $1.00.
- It holds US Treasury bills maturing within three months, which are direct obligations of the US government.
- The share price rises daily as interest accrues and drops on the monthly payout. That pattern is income, not a loss.
- SIPC covers your brokerage account to $500,000 if the firm fails. It does not cover price changes.
Common questions
No. FDIC insurance applies to deposits at insured banks, and SGOV is an exchange-traded fund, not a deposit. SGOV holds US Treasury bills maturing within three months, which are direct obligations of the US government. Shares held at a brokerage are covered by SIPC up to $500,000 if the brokerage fails, which is separate from FDIC insurance and does not protect against price changes.
No. SGOV is an ETF that holds short-term Treasury bills. A money market fund is a mutual fund that aims to hold a constant $1.00 share price and transacts once a day. SGOV trades on an exchange throughout the day and its share price moves, rising as interest accrues and dropping when it pays its monthly distribution.
Its share price can dip slightly, and it drops each month by the amount of the distribution it pays. Because it holds Treasury bills maturing within three months, interest rate changes have had very little effect on its price, and past dips have been small and short. Past performance does not guarantee future results.
They are safe in different ways. A savings account has a fixed balance and FDIC insurance up to $250,000. SGOV holds US Treasury bills, carries no deposit insurance, and has a share price that moves by small amounts. SGOV's income is largely exempt from state income tax, while bank interest is not.
