As a finance professional, I often encounter investors who wonder whether open-ended mutual funds can be used as collateral for margin loans. The answer isn’t straightforward—it depends on brokerage policies, regulatory constraints, and the fund’s underlying assets. In this article, I’ll dissect the marginability of open-ended mutual funds, examining key factors that influence their eligibility, regulatory considerations, and practical implications for investors.

Understanding Marginability and Open-Ended Mutual Funds
What Are Open-Ended Mutual Funds?
Open-ended mutual funds are investment vehicles that pool money from multiple investors to buy a diversified portfolio of stocks, bonds, or other securities. Unlike closed-end funds, which trade on exchanges like stocks, open-ended funds issue and redeem shares directly with investors at the net asset value (NAV) per share.
The NAV is calculated as:
\text{NAV} = \frac{\text{Total Assets} - \text{Total Liabilities}}{\text{Number of Outstanding Shares}}What Does “Marginable” Mean?
A security is marginable if a brokerage allows investors to use it as collateral for a margin loan. The Federal Reserve’s Regulation T and brokerage house rules determine which assets qualify.
Are Open-Ended Mutual Funds Marginable?
The short answer: Sometimes, but not always.
Key Factors Influencing Marginability
- Brokerage Policies
- Some brokerages permit margin loans against mutual funds, while others exclude them entirely.
- Example: Fidelity allows certain proprietary mutual funds as margin collateral, while others may not.
- Fund Composition
- Funds holding highly liquid securities (e.g., large-cap stocks) are more likely to be marginable.
- Funds with illiquid assets (e.g., private equity, real estate) are typically excluded.
- Regulatory Requirements
- FINRA and SEC rules require brokerages to apply haircuts (discounts) to collateral value.
- The standard haircut for mutual funds is typically 30%, meaning only 70% of the NAV can be borrowed against.
Example Calculation: Margin Loan Against a Mutual Fund
Suppose you own $100,000 worth of a marginable open-ended mutual fund. If the brokerage applies a 30% haircut:
\text{Loan Value} = \$100,000 \times (1 - 0.30) = \$70,000This means you can borrow up to $70,000 against your fund holdings.
Comparing Marginability Across Asset Classes
| Asset Type | Typical Marginability | Haircut (%) |
|---|---|---|
| Large-Cap Stocks | Yes | 25-30% |
| Open-Ended Mutual Funds | Varies by Brokerage | 30-50% |
| ETFs | Usually Yes | 25-30% |
| Bonds (Investment-Grade) | Yes | 15-30% |
| Illiquid Securities | No | N/A |
Why Mutual Funds Are Less Frequently Marginable Than ETFs
- Redemption Process: Mutual funds settle trades at end-of-day NAV, whereas ETFs trade intraday like stocks.
- Liquidity Concerns: Some mutual funds hold less liquid assets, making them riskier collateral.
Risks of Using Mutual Funds as Margin Collateral
- Market Volatility Impact
- If the fund’s NAV drops significantly, the brokerage may issue a margin call, forcing you to deposit more funds or liquidate positions.
- Interest Costs
- Margin loans accrue interest, which can erode returns if the fund underperforms.
- Regulatory Changes
- Brokerages can revise margin requirements, reducing the loanable value of your holdings.
Practical Considerations for Investors
When It Makes Sense to Use Mutual Funds as Collateral
- You need short-term liquidity but don’t want to sell long-term holdings.
- The fund is highly liquid (e.g., an index fund tracking the S&P 500).
When to Avoid It
- The fund is volatile or holds illiquid assets.
- You’re already highly leveraged.
Conclusion
While some open-ended mutual funds are marginable, their eligibility depends on brokerage policies, liquidity, and regulatory constraints. Investors should carefully assess the risks, including margin calls and interest costs, before pledging mutual funds as collateral. Always consult your brokerage’s margin agreement and consider alternative liquidity strategies if needed.
