OPER vs TBLL

OPERCClearShares Ultra-Short Maturity ETF

TBLLAInvesco Short Term Treasury ETF

In short

OPER Most cash-parking ETFs buy T-bills. OPER goes upstream into the overnight repo market, lending against U.S. government collateral, the same plumbing money funds run on. Actively managed, pays monthly, trading since 2018.

TBLL The bill fund that stretches to a full year. TBLL owns U.S. Treasuries maturing in one year or less and charges 0.08%, well under the typical fund in its 0-1 year Treasury group.

Stated mandate

OPER The Fund seeks current income. It is actively managed and primarily invests in repurchase agreements collateralized by U.S. government securities, with lesser investments in individual fixed-income instruments.

TBLL The fund invests primarily in U.S. Treasury obligations with maturities of one year or less and seeks exposure to the ICE U.S. Treasury Short Bond Index.

Why people hold it

• OPER Built around repurchase agreements collateralized by U.S. government securities, so the income comes from short-term funding markets rather than from reaching down the credit ladder.
• Narrow mandate, faithfully executed: what the prospectus describes is what the portfolio holds, one of the tightest mandate-to-portfolio matches in the cash-alternative group.
• Distributions land monthly, which fits how a cash sleeve actually gets used. Live since 2018, so it has operated through both near-zero and high short-term rate environments.

• TBLL Charges 0.08% a year against a 0.14% median for its 0-1 year Treasury cohort, and undercuts BIL, the 1-3 month bill fund at 0.14%.
• Fishes the entire under-one-year curve, about 90 Treasury positions, instead of camping in 1-3 month paper like much of the peer shelf.
• Live since 2017 and a multi-billion-dollar fund, with index tracking among the tighter implementations in its 17-fund group.
• Distributions land monthly, and the portfolio is Treasury obligations only, so no corporate credit rides along.

Worth knowing

• OPER The 0.20% expense ratio sits mid-aisle. ICSH charges 0.08% and JPST 0.18%, so the repo-first approach costs a little more than the cheapest cash parkers.
• It trades lightly next to the category's household names, so the spread at the moment of the trade matters more here than with the most heavily traded peers.
• Small asset base compared with the multi-billion-dollar funds in this corner, and it is an active ETF, not a money market fund, so the share price floats.

• TBLL Not the cheapest seat in the row: XONE runs 0.03% and VBIL 0.06%, so the cost gap is a few basis points.
• Reaching out to one-year maturities carries slightly more interest-rate sensitivity than a strict 1-3 month bill portfolio.
• Moderately traded rather than the volume leader of its category, so spreads deserve a look on larger orders.
