Our read on each fund

ETF.net Research

TBLLAInvesco Short Term Treasury ETF

WEEKBRoundhill Weekly T-Bill ETF

In short

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.

WEEK A T-bill fund built around the calendar. WEEK holds Treasury bills maturing in 0 to 3 months, aims to pay every week, and sizes those payments to hold its NAV steady week over week. It launched in 2025 as the first of its kind.

Stated mandate

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.

WEEK The Fund seeks weekly distributions of current income by investing primarily in U.S. Treasury bills maturing within 0 to 3 months at purchase. It is actively managed and seeks to maintain a stable week-over-week NAV.

Why people hold it

  • 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.
  • WEEK Income arrives as weekly cash, not accrual: the fund targets a distribution every week, sized to keep NAV level week over week.roundhillinvestments.com
  • An actively managed bill ladder someone else rolls: it buys Treasury bills maturing within 0 to 3 months and handles the reinvestment as they mature.roundhillinvestments.com
  • Holdings match the label: US Treasury bills, no reach into commercial paper or corporate credit to pad the payout.

Worth knowing

  • 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.
  • WEEK The weekly plumbing costs more than the aisle: 0.19% a year, against a category median of 0.14% and cheaper bills funds like VBIL at 0.06% and CLIP at 0.07%.
  • Not a money market fund: no fixed $1 NAV, and Roundhill discloses that payments exceeding income and gains are treated as return of capital.roundhillinvestments.com
  • A 2025 launch, mid-sized and moderately traded, so spreads and depth trail the entrenched giants of the T-bill aisle.
