If you parked $250,000 in iShares 0-3 Month Treasury Bond ETF (NYSEARCA:SGOV) in the summer of 2024, your August paycheck was roughly $1,127. This August, the same stake paid about $763. The share price barely changed, but the monthly income fell by roughly one-third as short-term interest rates declined. That is the trade-off investors can overlook with cash-like ETFs: principal may remain stable while the income resets lower with interest rates.
What You’re Actually Paying
SGOV’s expense ratio is 0.09%, gross and net, per the prospectus dated June 29, 2026. On $10,000, that is just $9 a year. On $250,000, iShares takes about $225 a year, or roughly $18.75 out of every monthly distribution before you see it.
That $225 looked trivial in 2024, when the fund was providing more than $1,100 a month on a $250,000 balance. It looks different now. Monthly income has fallen from a 2024 peak per-share dividend of $0.458091 (February 2024) to $0.306812 (August 2026). The fee did not shrink with the paycheck. The Federal Funds target was 4.5% a year ago and sits at 3.75% today after three cuts between September and December 2025. Short T-bill yields followed: the 4-week bill now yields 3.7% and the 13-week 3.81% as of August 17, 2026. Your gross yield fell about 75 basis points. Your fee stayed at 9.
The Part the Factsheet Doesn’t Highlight
A flat 0.09% only sounds like a fixed cost. In practice, it is a fixed piece of a shrinking pie. When SGOV yields 5.3%, the fee eats about 1.7% of your gross income. When it yields 3.8%, the same fee eats closer to 2.4% of gross income. As a result, the expense ratio becomes a larger drag on the income the fund generates.
There is also a second cost the factsheet buries: SGOV distributes ordinary income, taxable at your marginal federal rate. On a $250,000 balance producing roughly $3.76 per share over the trailing 12 months, that is thousands in interest reported on your 1099. State tax treatment of the Treasury portion typically flows through, but ETF wrappers and any non-Treasury cash holdings can dilute the state exemption compared with holding bills directly. On top of that, the price has crept from $96.88 to $100.58 over the past year, so a sale before a distribution can turn interest into short-term gains at the wrong tax rate.
The Cheaper Mirror
You can buy the exact securities SGOV holds. Four-week and 13-week Treasury bills, auctioned every week through TreasuryDirect or your broker, carry no expense ratio and are fully exempt from state and local income tax on the interest. The trade-off is real: you manage the roll, you lack intraday liquidity, and small balances get fiddly. Larger, ultra-cheap short-Treasury ETFs from Vanguard and State Street exist in the same corner of the curve at expense ratios in the same neighborhood, so the swap is measured in single-digit basis points, not necessarily an alternative.
The point is the gap is avoidable. A do-it-yourself T-bill ladder on $250,000 gives back the roughly $225 a year SGOV collects, and it does so without changing your interest-rate exposure by a single basis point.

What This Means for You
SGOV is behaving exactly as a 0-3 month T-bill ETF should when the Fed cuts. The question worth asking is whether you are paying a convenience premium that made sense at 5.3% yields and makes less sense at 3.81%. If your cash pile is large and your holding period is long, the fee is not the headline. It is simply the line item that never renegotiates when your paycheck does.
