description: Tokenized money market funds providing yield-bearing treasury management for institutions. Unlike stablecoins (which typically don't earn yield), money market funds are productive assets generating returns. Institutions prefer MMFs over non-yield stablecoins for treasury management but require privacy for position sizes and yield strategies.

## Problems

### Problem 1: Position and Strategy Privacy

Large MMF positions reveal treasury management strategies and cash reserves. Competitors can infer financial health and business plans from position sizes.

**Requirements:**

* **Must hide:** Position sizes, subscription/redemption timing, yield optimization strategies
* **Public OK:** Fund NAV, total AUM, portfolio composition (at aggregate level)
* **Regulator access:** Investor concentration monitoring, liquidity stress testing data, SEC reporting

**Constraints:**

* Daily NAV calculations
* SEC Rule 2a-7 compliance (for US funds)
* Liquidity requirements for redemptions

### Problem 2: Redemption Pattern Privacy

Redemption patterns signal liquidity needs or market views. Large redemptions can trigger runs if publicly visible.

**Requirements:**

* **Must hide:** Individual redemption requests, timing, amounts
* **Public OK:** Aggregate fund flows (delayed)
* **Regulator access:** Liquidity monitoring, stress scenario analysis

**Constraints:**

* Same-day or T+1 redemption requirements
* Gate and fee provisions
* Systemic risk monitoring obligations

## Recommended Approaches

See detailed solution architecture and trade-offs in [**Approach: Private Money Market Funds**](/approaches/approach-private-money-market-funds/). Key considerations:

* Privacy-preserving subscription/redemption mechanisms
* Confidential NAV sharing with authorized parties
* Integration with custody and settlement infrastructure

## Open Questions

* How does yield attribution work with position privacy?
* What's the relationship to stablecoin privacy patterns?
* How to handle fund gates/fees with position privacy?

* Differentiation: Unlike stablecoins, money market funds earn yield. Institutions prefer MMFs over non-yield stablecoins for treasury management.
* Market context: Tokenized treasuries/MMFs are among the largest RWA categories outside stablecoins
