Coinbase is pointing to a $22 billion money market ETF as a major new tool for stablecoin reserve management. The fund, IQMM, launched in February 2026 and is described as the first money market ETF built specifically for stablecoin reserves under the GENIUS Act.
IQMM is built around reserve compliance
Under the GENIUS Act, stablecoin issuers must fully back reserves with high-quality, highly liquid assets. IQMM is structured around that requirement. Its holdings include US Treasury securities with maturities of 93 days or less, along with cash and cash equivalents. Coinbase said existing cash-management tools were not designed for this market, while IQMM was built with stablecoin issuers’ reserve needs in mind.
A money market ETF usually holds short-term, lower-risk instruments and gives investors organized access to cash-like assets. In the stablecoin market, that matters less for trading and more for reserve operations. A short point, but a critical one. Coinbase’s message is that reserve management is becoming just as important as payment rails and distribution networks.
Always-on settlement raises demand for stronger reserve infrastructure
The source notes that stablecoins now operate 24/7 and provide instant settlement for both individuals and corporations. That has increased demand for dependable reserve infrastructure. IQMM is positioned as a way to address gaps in reserve management, liquidity planning, and issuance and redemption workflows.
Coinbase argues that reserve operations have so far depended heavily on a narrow set of banking and cash-management channels. That setup is now being challenged. The company’s view is straightforward: the sector needs better systems not only for moving stablecoins, but also for managing the money that stands behind them.
Coinbase extends its stablecoin push into reserve operations
Coinbase already offers products tied to stablecoin distribution, payments, and developer tools. This move pushes that strategy deeper into reserve operations and cash management. The company is signaling that it wants exposure across more stages of the stablecoin lifecycle, not just trading or transfers.
The source also says the GENIUS Act has created clearer rules around reserve backing. That brings new compliance obligations, and it also opens a market for products built around those rules. Coinbase sees its ProShares-related move as an early step in that shift. ProShares’ more than 20 years of ETF experience is presented as an important factor for reserve instruments that sit between crypto markets and traditional capital markets.
