SGOV vs USFR: Which Treasury Cash ETF Is Better?

SGOV and USFR are both Treasury cash ETFs, but not the same fund. SGOV holds 0-3 month T-bills; USFR holds floating rate notes. How they differ, how each is taxed, and which to pick, with an after-tax yield calculator.

The Answer in One Sentence

SGOV and USFR are both good Treasury cash ETFs. SGOV is the simpler, cheaper default; USFR is the slightly more technical floating-rate alternative. The right answer depends less on the ticker and more on after-tax yield, liquidity needs, state tax treatment, and whether this money is truly cash or long-term portfolio capital wearing a cash costume. For most DIY investors holding cash in a taxable brokerage account, SGOV is the cleaner default. USFR is worth it when its after-tax yield edge is meaningful, or when you specifically want a coupon that resets weekly with 13-week Treasury bill rates.

What SGOV Owns

SGOV is the iShares 0-3 Month Treasury Bond ETF. It tracks an index of U.S. Treasury bills with 0 to 3 months of remaining maturity, which BlackRock positions as a way to preserve capital and manage liquidity with minimal interest-rate risk. As of July 1, 2026 it held roughly $94.7 billion, charged a 0.09% expense ratio, posted a 3.56% 30-day SEC yield, and carried a 0.11-year effective duration, a 0.11-year weighted average maturity, and a 0.01% median bid/ask spread. Its portfolio was 99.57% U.S. Treasury debt.

In plain terms, SGOV is a rolling basket of very short Treasury bills inside an ETF wrapper. It is not a bank account, but it behaves like one of the lowest-volatility Treasury options available to ordinary investors.

What USFR Owns

USFR is the WisdomTree Floating Rate Treasury Fund. It tracks the Bloomberg U.S. Treasury Floating Rate Bond Index, holding newly issued U.S. Treasury floating rate notes (FRNs). As of its March 31, 2026 fact sheet it held roughly $17.6 billion, charged a 0.15% expense ratio, posted a 3.60% 30-day SEC yield, and carried a 0.02-year effective duration, with its holdings entirely in FRNs maturing inside two years.

The distinction is that USFR does not hold 0-3 month bills. It holds Treasury FRNs. Per TreasuryDirect, an FRN matures in two years, pays interest quarterly, and carries a rate equal to an index rate plus a fixed spread set at auction. The index rate is tied to the highest accepted discount rate of the most recent 13-week Treasury bill auction and resets weekly.

Why USFR’s maturity is longer but its duration is shorter

A fixed-rate two-year Treasury note can move meaningfully in price when rates change. A two-year floating-rate note resets its coupon every week, so its price barely reacts to rate moves. That is why USFR can own longer-dated securities than SGOV while reporting an even lower effective duration (0.02 years vs 0.11). The coupon does the adjusting, not the price.

SGOV data from iShares (Jul 1, 2026); USFR data from the WisdomTree fact sheet (Mar 31, 2026). The two SEC yields carry different as-of dates. Both figures are 30-day SEC yields, not distribution or trailing yields, which run higher. Yields move week to week; check current numbers before deciding.

How They Are Similar

  • Treasury-focused and low credit risk. Both give brokerage investors exposure to U.S. government obligations.
  • Monthly income. Both distribute income monthly.
  • Very low duration. SGOV through ultra-short bill maturity, USFR through weekly coupon resets. Different mechanics, similar result.
  • Federally taxable. Treasury income is subject to federal income tax.
  • Usually state-tax advantaged. Income from U.S. Treasury obligations is generally exempt from state and local income tax, subject to your state’s rules and the fund’s annual government-source percentage.
  • Not FDIC insured. Neither is a bank deposit. There is no FDIC or government guarantee, and principal can fluctuate.

Tax Treatment

Federal

In a taxable account, both funds’ distributions are taxed as ordinary income at the federal level. Because these are ETFs, you receive a Form 1099-DIV, not the 1099-INT you would get from holding Treasuries directly. That does not make the income federally tax-free; it is passed through by a regulated investment company. Per IRS Topic 403, Treasury interest is federally taxable but exempt from state and local income tax.

State and local

This is where Treasury ETFs can beat high-yield savings accounts, CDs, and many money market funds in high-tax states. The catch is that the state-exempt share is not always 100%, and tax software does not always apply it automatically. For 2025, iShares reported SGOV at 95.14% U.S. government source income. USFR holds close to 100% Treasury FRNs, so essentially all of its income is U.S. government source and its state-exempt share is typically near 100%. Confirm the exact figure on WisdomTree’s annual tax supplement, since the percentage and your state’s threshold rules both matter.

Capital gains

Sell above your cost basis and you have a capital gain; sell below it and you have a loss. These funds are very low volatility, so the amounts are usually small, but they are not always zero. This is why they belong in the “cash-like” bucket rather than being treated as literal cash.

Run Your Own After-Tax Numbers

The correct choice depends on your federal rate, state rate, the current yields, and how much you hold. The comparator below computes the after-tax yield for SGOV, USFR, and a HYSA, and the break-even HYSA APY you would need to match SGOV after tax.

A fully taxable HYSA must yield at least this much to match SGOV after your federal and state tax. Your HYSA is at 4.00%.

SGOV vs USFR

USFR wins after tax by $22/yr on $50,000. That gap is tiny. Pick the cheaper, simpler fund and move on.

How the calculator works

A 30-day SEC yield is already net of the expense ratio, so the tool does not subtract fees a second time. It applies federal tax to all income and state tax only to the non-exempt fraction of Treasury income. The break-even figure inverts SGOV’s after-tax yield back into the pre-tax APY a fully taxable account would need to match it.

SGOV and USFR Are Not the Only Options

  • Need FDIC insurance or instant bank access? Use a HYSA, money market deposit account, or CD ladder. FDIC insurance covers $250,000 per depositor, per insured bank, per ownership category.
  • Need brokerage cash-like exposure with state-tax benefits? SGOV or USFR fit.
  • Want the simplest Treasury cash ETF? SGOV.
  • Want ultra-low-duration floating-rate exposure? USFR.
  • Need exact maturity matching? Buy Treasury bills directly or build a bill ladder.
  • Need same-day cash? Do not rely only on ETFs. U.S. ETFs settle T+1, so proceeds are not instantly available.

The Economics of Cash

Safe cash-like instruments are not built to compound wealth. They are valuable because they are safe, liquid, and reliable. Over the long run, cash and bills are the lowest-returning major asset class. The Dimson-Marsh-Staunton data summarized in the UBS Global Investment Returns Yearbook 2024 puts real annual returns since 1900 at roughly 5.1% for global equities, 1.7% for bonds, and 0.3% for Treasury bills.

Two mistakes follow from ignoring this. Some investors leave large balances in a near-zero bank sweep and give up real yield. Others treat a 5-to-15 basis point difference between two Treasury ETFs like a major portfolio decision. Cash is for known liabilities, reserves, tax payments, and psychological stability. Long-term growth belongs to diversified risky assets, not to a cash ETF.

Who SGOV Makes Sense For

  • Taxable brokerage cash and emergency-fund overflow.
  • Down payments due in the next 0-24 months.
  • Estimated tax payments and RSU proceeds awaiting reinvestment.
  • Investors in high-tax states using the Treasury state-tax exemption.
  • DIY investors who want simplicity and do not want to run Treasury auctions.

Less so for: anyone who needs FDIC coverage, instant checking access, cash before a trade settles, or who is using “cash” as a market-timing substitute for a long-term allocation.

Who USFR Makes Sense For

  • Investors who understand floating-rate Treasury mechanics.
  • Investors who want Treasury exposure with the lowest possible duration.
  • Investors who see a meaningful after-tax yield advantage right now.
  • Investors comfortable with a slightly more technical structure and a review of the annual tax supplement.

Less so for: anyone who wants the simplest possible explanation, who would be unsettled to learn the fund’s average maturity is longer than SGOV’s, or who is chasing a few basis points of last month’s yield.

What I Recommend

Default to SGOV. It is cheaper, larger, more liquid, and easier to explain: cash in very short Treasury bills, low fees, high liquidity. Reach for USFR when the after-tax yield spread is real and worth the extra complexity, or when you specifically want weekly floating-rate exposure. In most conditions the gap is small enough that the tie-breaker is fees and simplicity, both of which favor SGOV. This is a basis-points and mechanics decision, not a core portfolio decision.

Mistakes to Avoid

  • Treating ETF shares as FDIC-insured bank deposits.
  • Ignoring T+1 settlement when you need cash on a specific day.
  • Chasing last month’s distribution yield and confusing it with the SEC yield.
  • Forgetting to apply the fund’s state-exempt percentage at tax time.
  • Parking long-term money in a cash ETF because volatility feels uncomfortable.

How Summitward Helps

Summitward turns this from a ticker debate into a household decision. Map your cash into buckets (emergency fund, tax reserve, down payment, RSU proceeds, and investable long-term capital), then compare after-tax yields across SGOV, USFR, HYSAs, CDs, money market funds, and direct T-bills with your own federal and state rates. The tools flag the difference between same-day bank cash and T+1 ETF settlement, and the opportunity cost of holding more cash than your liabilities require.

Frequently Asked Questions

Is SGOV or USFR better?

For most DIY investors, SGOV is the better default: lower expense ratio (0.09% vs 0.15%), larger and more liquid, tighter bid/ask spread, and simpler to explain. USFR is better when its after-tax yield is meaningfully higher or you want a coupon that resets weekly with 13-week bill rates. The practical difference is usually small.

Are SGOV and USFR taxed the same way?

Broadly yes. Both distribute ordinary income reported on a 1099-DIV, federally taxable and generally state-exempt as U.S. Treasury income. The state-exempt percentage differs: iShares reported SGOV at 95.14% for 2025, while USFR’s all-FRN portfolio runs close to 100%. Check each fund’s annual tax document for the exact figure.

Why does USFR have a longer maturity but a shorter duration?

USFR holds two-year Treasury floating rate notes, but their coupons reset weekly. Frequent resets keep the price from reacting to rate changes, so the effective duration (0.02 years) is even lower than SGOV’s (0.11), despite the longer stated maturity.

Should I hold both SGOV and USFR?

There is little reason to. They own the same issuer, the U.S. Treasury, so holding both adds no diversification. Pick the one that fits your preference for simplicity (SGOV) or floating-rate mechanics (USFR).

Are these a replacement for a savings account?

Only partly. They often beat a HYSA after tax in high-tax states, but they are not FDIC insured and settle T+1. Keep genuinely immediate cash in a checking or savings account, and use SGOV or USFR for the reserve layer you can access within a day or two.

Key Takeaways

  • SGOV is the simpler default. Cheaper (0.09%), larger, more liquid, and holds 0-3 month Treasury bills.
  • USFR is a strong floating-rate alternative. It holds Treasury FRNs that reset weekly, with an even lower duration and a slightly higher fee.
  • The gap is usually a few basis points. Compare after-tax yields; do not over-optimize a small difference.
  • Both are federally taxable and mostly state-exempt. SGOV was 95.14% state-exempt for 2025; USFR runs near 100%. Apply the percentage at tax time.
  • Neither is FDIC insured, and both settle T+1. Keep truly immediate cash in a bank account.
