Closed-end funds can be purchased on margin at most brokerages because they trade on stock exchanges and qualify as margin securities under Federal Reserve Regulation T. The federal minimum is 50% of the purchase price in your own capital, with the broker lending the rest, but individual firms often demand more equity, exclude low-priced or thinly traded CEFs entirely, and can change the rules on a specific fund at any time. Margining a CEF also carries risks that don’t show up when you margin an ordinary stock, and those are the risks worth understanding before you place the trade.
Why CEFs Are Eligible for Margin
Regulation T governs how much credit a broker-dealer can extend for securities purchases. Because closed-end funds are listed on exchanges like the NYSE or Nasdaq, they meet Reg T’s definition of a margin security. Open-end mutual funds don’t: they’re redeemed through the fund company rather than traded on an exchange, and they generally cannot be bought on margin.
Eligibility isn’t permanent. A CEF can lose margin status if it is delisted, drops below continued listing standards, or if the broker decides it no longer meets internal risk criteria. Confirm margin eligibility for the specific fund with your broker before placing the order rather than assuming past treatment carries over.
Minimum Equity and the 50% Initial Requirement
FINRA sets a baseline of $2,000 in equity to open and use a margin account. If the total purchase costs less than $2,000, you deposit the full purchase price in cash.1FINRA. FINRA Rule 4210 – Margin Requirements
Above that floor, Regulation T requires 50% initial margin on equity securities, including CEFs. Buying $20,000 of a closed-end fund means putting up at least $10,000 of your own capital and borrowing the other $10,000 from the broker.2Financial Industry Regulatory Authority. Margin Regulation
The 50% figure is a federal floor, not the number you’ll always see. Brokers routinely require 60% or 70% initial equity for a CEF that swings in price or trades few shares a day. Some firms make certain CEFs entirely non-marginable when the share price falls below a threshold such as $3 or $5, since low-priced securities are weak collateral.
Maintenance Margin and Margin Calls
Once you own the position, the initial rule stops mattering. What matters from that point on is maintenance margin: the minimum equity percentage your account must carry at all times. FINRA Rule 4210 sets the floor at 25% of the current market value of long positions.1FINRA. FINRA Rule 4210 – Margin Requirements Most brokers set a house requirement higher, often between 30% and 40%.3Securities and Exchange Commission. Investor Bulletin: Understanding Margin Accounts
A worked example. You buy $20,000 of a CEF, putting up $10,000 and borrowing $10,000. Your broker requires 30% maintenance equity. The position falls to $13,000. Your equity is now $3,000, which is 23% of market value. You’re below the 30% threshold, so the broker issues a margin call, and you’d need to deposit enough cash or additional securities to bring equity back to 30% of the position’s current value, roughly $900 in this case.
Forced Liquidation
If you can’t meet the call, or even if you can but the broker chooses not to wait, the firm has the right to sell securities in your account without contacting you first. The required FINRA margin disclosure statement is explicit: a firm can immediately sell securities without notice, and you don’t choose which positions get liquidated.4FINRA. FINRA Rule 2264 – Margin Disclosure Statement
Most firms will try to reach you, and many offer a window of two to five business days to meet the call. They aren’t required to. In fast-moving markets, firms protect their own capital first, and the position they sell may be your highest-conviction holding rather than the one you’d have picked.
Risks That Are Specific to CEFs
Buying any security on margin amplifies gains and losses. CEFs add structural quirks that make margin more dangerous than it is with a typical stock or ETF.
Discount and Premium Swings
A CEF’s share price is set by supply and demand on the exchange and can diverge significantly from the net asset value of the underlying holdings. A fund might trade at a 5% discount to NAV one month and a 15% discount the next while the portfolio itself barely moves.
Your maintenance requirement is calculated on the market price of your shares, not on NAV. If sentiment sours on a sector or on CEFs broadly, the discount can widen sharply, driving the share price down independent of portfolio performance. You can be right about the underlying investments and still get a margin call because the market repriced the wrapper.
Leverage Stacked on Leverage
Most closed-end funds borrow money at the fund level to boost returns. Under the Investment Company Act of 1940, a CEF issuing debt must maintain at least 300% asset coverage, capping debt leverage at roughly 33% of total assets; preferred stock is capped at 200% coverage, allowing up to 50%.5Office of the Law Revision Counsel. 15 U.S. Code 80a-18 – Capital Structure of Investment Companies Leverage ratios of 25% to 35% are common.
When you buy a leveraged CEF on margin, you stack personal borrowing on top of the fund’s borrowing. A 10% decline in the fund’s underlying assets hits NAV harder because of the fund’s own debt, and that magnified NAV drop hits your equity even harder because of the margin loan. This double-leverage effect is where accounts blow up during corrections.
Distributions Aren’t the Buffer They Look Like
CEFs draw income investors with generous monthly or quarterly distributions, and those payments feel like a cushion against margin risk. They aren’t as protective as they appear.
Cash distributions received in a margin account typically reduce your debit balance automatically, which lowers borrowing costs slightly. The distribution also reduces the fund’s share price by roughly the same amount on the ex-date. Your loan balance drops, but so does the market value of your collateral. The net effect on your equity percentage is minimal, and if the share price is falling for other reasons, distributions won’t stop a margin call.
A portion of many CEF distributions is classified as return of capital rather than investment income. Return of capital means the fund is sending back some of your own investment. Your cost basis drops, but your margin loan doesn’t care about cost basis. The loan balance stays the same regardless of how the distribution is categorized.
What the Loan Costs You
Margin loans aren’t free, and for CEF investors chasing yield, the interest cost eats directly into the income advantage that drew them to the fund. Brokers charge interest on the outstanding margin balance, calculated daily and billed monthly.
Rates vary widely. As of early 2026, competitive brokers charge roughly 4% to 6% on six-figure balances, while several major full-service firms charge over 10% on smaller loans. If you’re holding a CEF yielding 8% on margin at 10.5% interest, you’re paying more to borrow than you’re collecting in distributions. Even at 5%, a meaningful share of the distribution goes to servicing the loan rather than building wealth.
Rates are also variable. Most brokerage margin rates are tied to a benchmark like the federal funds rate, so borrowing costs can rise even though your position and distribution income haven’t changed.
Tax Treatment of the Interest
Interest paid on a margin loan used to buy investment securities is classified as investment interest expense and is potentially deductible on your federal return. Two catches matter.
You have to itemize on Schedule A to claim it. If you take the standard deduction, the margin interest gives no tax benefit.6Internal Revenue Service. Publication 550 (2025), Investment Income and Expenses The deduction is also capped at your net investment income for the year. Net investment income includes taxable interest, non-qualified dividends, and short-term capital gains, but not long-term capital gains or qualified dividends unless you elect to treat them as ordinary income. Excess margin interest carries forward.7Internal Revenue Service. About Form 4952, Investment Interest Expense Deduction
For CEF investors this limitation bites. Many CEF distributions include qualified dividends, return of capital, or long-term gains, none of which count toward net investment income under the default rules. You could owe substantial margin interest with relatively little deductible income to offset it. Running Form 4952 numbers before committing to a leveraged CEF strategy is worth the effort.
When Margin on a CEF Makes the Least Sense
Certain CEF characteristics make margin riskier than usual. Funds trading at narrow premiums to NAV are exposed to discount widening that can erase the premium and drive the share price down quickly. Funds with leverage ratios near the statutory limits are already amplifying portfolio moves before you add margin. Funds paying distributions primarily from return of capital may be eroding their own asset base, weakening the collateral behind your loan over time.
CEFs trading at wide discounts to NAV with low fund-level leverage and distributions well-covered by investment income present a more favorable profile for margin use, though the interest cost still has to make sense against the yield. And remember that margin requirements and eligibility can change without warning; brokers retain full discretion to raise requirements or restrict margin on specific securities at any time.2Financial Industry Regulatory Authority.
