New Money Market ETF Draws $2.1B in First Week
- The Simplify Government Money Market ETF (SBIL) amassed $2.1 billion in AUM in its first week of trading.
- It joins a short list of true money market ETFs launched in the past year.
A new money market ETF just launched, and it's already making waves.
The Simplify Government Money Market ETF (SBIL) amassed $2.1 billion in assets under management in its first week of trading, a rare feat for a freshly launched fund.
The ETF began trading on July 14 and is part of a small but growing group of money market ETFs built specifically to comply with Rule 2a-7 under the Investment Company Act of 1940, the same rule that governs traditional money market mutual funds.
Unlike classic money market funds, which are priced once daily and maintain a constant $1 net asset value (NAV), SBIL has a floating NAV and trades intraday like any other ETF. That’s a key benefit for institutional and retail investors alike, allowing them to move in and out of positions throughout the day without waiting for end-of-day pricing.
SBIL charges an expense ratio of 0.15%.
SBIL Part of a Broader Trend
SBIL’s debut comes amid surging demand for ultra-short-term bond ETFs and cash-like strategies more broadly. While technically labeled a money market ETF, SBIL isn’t radically different from other popular ultra-short Treasury ETFs like the iShares 0-3 Month Treasury Bond ETF (SGOV) or the SPDR Bloomberg 1-3 Month T-Bill ETF (BIL).
These funds invest in high-quality debt with very short maturities—typically under three months—resulting in minimal interest-rate risk and essentially no credit risk.
While SGOV and BIL hold only Treasurys, money market ETFs like SBIL adhere to 2a-7 requirements, which enforce strict rules around maturity, liquidity and credit quality. In practice, the differences are mostly technical. To investors, they all serve as short-term, cash-like vehicles.
A Budding Subcategory
SBIL joins a short list of true money market ETFs launched in the past year. The first was the Texas Capital Government Money Market ETF (MMKT), which debuted in 2024. Since then, BlackRock Inc. (BLK) has entered the space with the iShares Government Money Market ETF (GMMF) and the iShares Prime Money Market ETF (PMMF).
SBIL is by far the largest ETF in the money market ETF category, though the aforementioned SGOV and BIL dominate the broader ultra-short-term bond ETF space.
SGOV recently became the first such ETF to cross $50 billion in assets.
