CBIL provides targeted exposure to U.S. Treasury bills maturing between 3 and 12 months, capturing the sweet spot of the yield curve where rates are typically higher than ultra-short bills but volatility remains minimal. This positioning aims to maximize yield within the T-bill universe while maintaining near-cash liquidity.
How It Works
The fund holds a ladder of Treasury bills across the 3-12 month maturity spectrum, likely equal-weighted or duration-weighted to maintain consistent exposure as bills mature. As holdings approach the 3-month threshold, they're rolled into new 12-month bills, creating a perpetual intermediate-term Treasury portfolio. This approach captures higher yields than money market funds while avoiding the duration risk of longer-term Treasury ETFs.
Key Features
- Zero expense ratio makes it cheaper than any actively managed cash alternative or money market fund
- 3-12 month focus captures term premium unavailable in ultra-short bills without meaningful duration risk
- Direct Treasury ownership eliminates credit risk present in prime money market funds or bank deposits
Risks
- Opportunity cost risk if short-term rates spike — locked into lower yields until bills mature vs overnight funds
- Modest duration risk means 50-100bp rate spike could create 0.25-0.5% paper losses temporarily
- New fund with zero AUM faces potential liquidation risk if it fails to attract meaningful assets
Who Should Own This
Perfect for investors parking cash for 6-12 months who want better yields than savings accounts without touching corporate credit or duration risk. Also works as a bond allocation for extremely risk-averse retirees or as a temporary haven when inverting yield curves make longer bonds unattractive relative to bills.
