SGOV vs Buying Treasury Bills Directly: What Changes?
When you want your money to earn returns without taking on the risks of long-term investing, short-term US government debt may be worth exploring. Two options are buying Treasury bills directly or investing in SGOV, an exchange-traded fund (ETF) that holds very short-term US Treasury securities.
Although both provide exposure to US government debt, they work differently. With SGOV, you own shares in a fund. With direct Treasury bills, you own specific securities with defined maturity dates.
Understanding this distinction helps you compare costs, income, access to your money and investment risks.
1. What Are You Actually Buying?
SGOV: An exchange-traded fund
The iShares 0–3 Month Treasury Bond ETF, known as SGOV, is managed by BlackRock's iShares. It seeks to track an index of US Treasury bills with maturities of zero to three months.
You purchase shares through a brokerage account, just as you would buy shares in a company. The fund manages its holdings and distributes income generated by its investments.
SGOV provides ongoing exposure to short-term Treasury securities without requiring you to select and manage individual bills yourself.
Direct Treasury bills: Individual government securities
Treasury bills, or T-bills, are short-term securities issued by the US government. They are available in terms ranging from four weeks to 52 weeks.
Bills are generally purchased at a discount to face value. At maturity, the government pays the face value, and the difference between the purchase price and the amount received represents your return before applicable taxes and costs.
You can purchase bills through TreasuryDirect or through a bank, broker or dealer.
2. SGOV vs Direct Treasury Bills: Key Differences
| Feature | SGOV ETF | Direct Treasury bills |
|---|---|---|
| Ownership | Shares in an investment fund | A specific Treasury security |
| Maturity | Fund continuously manages its holdings | Each bill has a fixed maturity date |
| Income | Generally distributed monthly | Return received at maturity |
| Costs | 0.09% annual expense ratio, according to iShares | No TreasuryDirect purchase fee; broker charges may apply |
| Trading | Shares trade on an exchange during market hours | Can be held to maturity or sold through a broker or dealer |
| Reinvestment | Fund manages its portfolio; distributions may be reinvested through your broker | Eligible maturing bills can be reinvested |
| Price behaviour | Share price fluctuates | Selling before maturity may result in a gain or loss |
3. How Do Income and Distributions Work?
SGOV generally makes monthly distributions. The amount can change depending on the income generated by the fund's holdings and other factors. These distributions are not guaranteed.
Direct Treasury bills work differently. They generally do not pay periodic interest. Instead, investors receive the face value at maturity.
For example, if you purchase a Treasury bill for $9,900 and receive $10,000 at maturity, your return is $100 before applicable taxes and costs.
The timing of income may influence your choice. An investor who prefers regular distributions may appreciate SGOV's structure, while someone saving toward a specific future expense may prefer a bill that matures around the date the money is needed.
However, monthly distributions do not mean SGOV guarantees a particular monthly return.
4. Fees: What Does SGOV Cost?
According to iShares, SGOV's expense ratio is 0.09%.
This means annual operating expenses are equivalent to approximately $9 for every $10,000 invested, assuming the balance remains constant throughout the year. The expense is reflected in the fund's performance rather than normally appearing as a separate bill to the investor.
Direct Treasury bills purchased through TreasuryDirect have no TreasuryDirect purchase fee. However, brokers may charge transaction fees or apply other charges.
SGOV investors may also encounter brokerage commissions, bid-ask spreads or other account-related costs, depending on their platform.
When comparing costs, consider the entire investment process rather than looking at the expense ratio alone.
5. How Easy Is It to Access Your Money?
SGOV trades on an exchange during market hours. You can place an order to sell shares through your brokerage account, subject to market conditions, trading costs and settlement arrangements.
However, the selling price may be higher or lower than the price you paid. SGOV is an investment fund, not an insured bank deposit, and it does not guarantee that you can sell at a particular price.
Direct Treasury bills can be held until maturity, when the government pays their face value, assuming it meets its obligations. If you need your money earlier, you can sell through a broker or dealer, but the market price may differ from your purchase price.
TreasuryDirect also has a limitation worth knowing: newly purchased marketable securities generally must be held for at least 45 calendar days before they can be transferred to a broker or dealer for sale, subject to applicable exceptions. This can make TreasuryDirect less suitable if you anticipate needing to sell a short-term bill before maturity.
6. Price Behaviour: Can Either Investment Lose Value?
Both investments are exposed to market conditions, but their structures differ.
SGOV's share price can fluctuate as the market value of its holdings changes and distributions are paid. Its very short-duration portfolio is designed to limit sensitivity to interest-rate changes, but this does not eliminate investment risk.
A direct Treasury bill held to maturity generally pays its face value, assuming the US government meets its obligations. If you sell it early, however, the market price may be higher or lower than what you paid.
Neither option should be confused with an FDIC-insured savings account. Treasury securities are backed by the US government, while SGOV shares are investment fund holdings and are not insured bank deposits.
7. A Dated Comparison: What Do SGOV's Published Figures Show?
The following figures come from the iShares SGOV product page, dated 15–16 October 2026.
| SGOV measure | Published figure |
|---|---|
| Net asset value (16 October) | $100.58 |
| 52-week NAV range | $100.27 - $100.73 |
| One-day NAV change (16 October) | +$0.03 (+0.03%) |
| Year-to-date NAV total return (15 October) | +2.87% |
| 30-day SEC yield (15 October) | 3.74% |
| 12-month trailing yield (15 October) | 3.65% |
| Expense ratio | 0.09% |
These figures measure different things. Net asset value (NAV) is the value of one fund share. The 30-day SEC yield uses a standardised recent-income calculation, while the 12-month trailing yield reflects income over a longer historical period. Neither is a guaranteed future return.
The year-to-date total return measures performance from the beginning of the year to the stated reporting date. It should not be confused with an annual yield or a promise of future income.
To compare SGOV with direct Treasury bills properly, check the latest bill auction rate and the fund's latest published figures. Make sure you understand the yield conventions, dates, fees, taxes and holding periods before drawing conclusions.
The Bottom Line
SGOV offers a convenient way to maintain exposure to very short-term Treasury securities through a brokerage account, with monthly distributions and an ongoing fund expense ratio. Buying Treasury bills directly gives you ownership of a specific security with a defined maturity date.
Consider SGOV if you prefer ongoing fund exposure and exchange trading. Consider direct bills if you want to match a specific maturity to a planned financial goal.
Neither is automatically better. Compare current yields, costs, access and risks, and remember that a fund's yield is not the same as the return guaranteed by holding an individual Treasury bill to maturity.
