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 3 months or less, yields 0.09%, and carries 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 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 and uses floating-rate coupons tied to short-term reference rates, keeping duration very short while capturing a credit spread that Treasuries do not pay.
What SGOV Delivers Today
Yield behavior follows the T-bill curve almost point-for-point. The 3-month T-bill yields 3.72% as of June 16, 2026, and the 6-month sits at 3.80%. With the Fed funds upper bound at 3.75% and locked there since December 2025, monthly distributions have settled at around $0.30 per share. Over the past year, the return comes in at 3.94%, which works out to roughly $3,940 dollars on a $100,000 dollar position, 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 limitation is income. The risk profile is excellent, and the expense ratio is hard to beat, yet the payout reflects that Treasury holders are compensated for duration and credit risk, and this structure 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 pick up a different exposure. The natural move is senior secured corporate credit, where returns come from spread compensation rather than 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. 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. 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, including OCP CLO, Octagon, KKR, Ares, and Magnetite, with no single CLO exceeding 0.88% of net assets.
The dollar comparison favors JAAA. Its one-year total return is 5.05%, or roughly $5,050 on a $100,000 position, versus SGOV’s 3.94%. NAV stability has held: JAAA trades at $50.61 with a year-to-date price change of 2.03%, indicating most of the return comes from monthly distributions rather than price movement. Recent monthly distributions have run around $0.20 per share, down from $0.27 in 2024 as short rates have eased.
The Tradeoffs to Disclose
CLOs come with their own set of risks. 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, the NAV can move, as it briefly did in March 2020 before recovering. 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-cut risk is another factor to weigh. JAAA’s coupons float, so if the Fed resumes cutting rates, JAAA distributions will compress in step. Goldman Sachs projects another 50 basis points of cuts, bringing the target to 3-3.25% in 2026, while Vanguard expects the Fed to hold near its 3.5% neutral estimate. Both funds would see income decline, though JAAA’s spread over T-bills would likely persist.
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. 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 recent data points support JAAA as the higher-income option with comparable duration. 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.
