Holders of the iShares 0-3 Month Treasury Bond ETF (NYSEARCA:SGOV) own one of the simplest cash-equivalent products on the market. SGOV holds U.S. Treasury bills maturing in three months or less, carries a 0.09% expense ratio, and maintains close-to-zero duration risk. The appeal is straightforward: a place to park cash that earns the prevailing T-bill rate with state-tax-exempt income. The real question is whether a slightly different structure can deliver more income with a comparable duration profile, and a AAA-rated alternative has built a track record of doing exactly that.
That alternative is the Janus Henderson AAA CLO ETF (NASDAQ:JAAA), which holds the senior tranches of collateralized loan obligations rated AAA by major credit rating agencies. The fund pays monthly distributions, uses floating-rate coupons tied to short-term reference rates, and keeps duration very short while capturing a credit spread that Treasuries do not pay. With roughly $28.4 billion in assets, it has grown into one of the largest active fixed income ETFs in the market.
What SGOV Delivers Today
Yield behavior follows the T-bill curve almost point-for-point. The 3-month T-bill yields approximately 3.70% as of mid-July 2026, and SGOV’s 30-day SEC yield sits at 3.57%, reflecting the fund’s close tracking of front-end rates. The Fed funds upper bound has held at 3.75% since December 2025, and SGOV’s 12-month trailing yield stands at 3.80%. Over the trailing year, the total return comes in at roughly 3.9%, or about $3,900 on a $100,000 position. That result is a clean reflection of front-end rate exposure rather than any duration swing.
Where the Income Stops
The appeal is safety and cost, but the ceiling on income is structural. SGOV’s risk profile is excellent and its expense ratio is hard to beat, yet the payout reflects a simple reality: Treasury holders are compensated for duration and credit risk, and SGOV bears almost none of either. Anyone who wants more dollars per year on the same balance, without extending duration, has to step outside the Treasury market and accept a different kind of exposure. The natural move is senior secured corporate credit, where returns come from spread compensation rather than from the front end of the curve.
How JAAA Generates the Pickup
The structure sits at the top of the capital stack. JAAA holds AAA-rated CLO tranches that are paid first from the cash flows of diversified pools of senior secured corporate loans, with subordinated layers absorbing losses before they ever reach the top tier. The fund held 607 debt issues as of its Q1 2026 factsheet, with an effective duration of just 0.07 years, roughly equivalent to SGOV’s near-zero interest rate sensitivity. Historical default rates on AAA CLO tranches have been effectively zero across the asset class, although that record is backward-looking rather than a guarantee, a reminder of how capital structure and credit waterfalls shape the risk profile.
The yield mechanism is structural: CLO coupons float with short-term rates, so duration is near zero, similar to SGOV. The tranches pay a spread over the reference rate to compensate investors for the underlying loan exposure, and that spread is the source of the income pickup. JAAA’s expense ratio is 0.20%, higher than SGOV but modest for a credit product. Top positions are spread across managers such as KKR, Anchorage Capital, Carlyle, and Magnetite, with no single CLO exceeding approximately 1% of net assets.
The dollar comparison favors JAAA. Its one-year total return runs close to 5%, or roughly $5,000 on a $100,000 position, versus SGOV’s approximately 3.9%. The forward dividend yield is approximately 4.8%, and NAV has been stable at around $50.55, indicating most of the return comes from monthly distributions rather than price movement. Monthly distributions have averaged roughly $0.20 per share recently, reflecting the step-down in short rates since the Fed’s last cut in December 2025.
The Tradeoffs to Disclose
CLOs come with their own set of risks that are distinct from those of Treasury ETFs. AAA tranches sit at the top of the waterfall, but they still carry credit and liquidity exposure that Treasuries do not. In a severe dislocation, NAV can move, as it briefly did in March 2020 before recovering quickly. Tax treatment adds another wrinkle: SGOV income is exempt from state and local taxes, while JAAA distributions are fully taxable as ordinary income at the federal, state, and local levels. For investors in high-tax states, that difference eats into the pickup in headline yield and highlights the tradeoff between Treasury purity and structured credit.
Rate risk is another factor to weigh. JAAA’s coupons float, so if the Fed resumes cutting rates, distributions will compress in step. The rate outlook has shifted materially since this article was first written. Goldman Sachs, after stronger-than-expected jobs data in May and June 2026, scrapped its earlier calls for 2026 cuts entirely, pushing its forecast to June and December 2027, with a terminal rate still targeted around 3% to 3.25%. Goldman’s own confidence in that revised timeline is limited, assigning roughly 30% odds to its two-cut 2027 scenario. That uncertainty cuts both ways for JAAA holders: a prolonged hold keeps current spreads in place, while earlier-than-expected cuts would compress distributions faster. Either fund would see income decline if the Fed resumes easing, though JAAA’s spread over T-bills should persist regardless of direction.
How To Think About the Swap
The swap is cleaner in tax-deferred accounts, where the ordinary-income treatment of CLO distributions has no impact on after-tax returns. In taxable accounts, holders in high-state-tax jurisdictions can weigh the state-tax exemption on SGOV income against the credit spread on JAAA before moving the full position. A partial reallocation, keeping a portion in SGOV for true cash needs and shifting the rest into JAAA, captures part of the income pickup without committing the entire balance to credit risk.
For investors who hold SGOV strictly as a yield vehicle, the data support JAAA as the higher-income option with a comparable duration profile. For those who hold SGOV specifically for Treasury exposure and zero credit risk, JAAA does not fit the goal, and the incumbent stays in place.
Editor’s note: This update refreshes SGOV’s 30-day SEC yield to 3.57% and 12-month trailing yield to 3.80% as of mid-July 2026, updates JAAA’s forward dividend yield to approximately 4.8%, AUM to roughly $28.4 billion, and effective duration to 0.07 years per the Q1 2026 factsheet, and corrects the Goldman Sachs rate-cut outlook to reflect the bank’s June 2026 decision to remove all 2026 cut expectations and push its forecast to June and December 2027.
