Fully Paid Securities Lending Explained

Fully paid securities lending is the arrangement that lets your broker borrow stock you own outright and lend it on to someone who has to deliver real shares, usually a short seller. You keep the price exposure and you collect part of the fee the borrower pays. What you hand over is narrower than it sounds, and specific: the vote, SIPC coverage on the loaned position, the tax character of a dividend that lands mid-loan, and any certainty about how long the loan lasts.

How does fully paid securities lending work?

Start at the borrower's end. A short sale is a sale of stock the seller does not own, and it settles like every other sale: under T+1, real shares reach the buyer one business day later. The seller's broker has to locate those shares first, and the lender at the other end of that locate is very often another broker's retail customer.

Fully paid is the load-bearing term here. It means shares owned free and clear, bought with your own cash and never pledged against a margin debit. Under SEC Rule 15c3-3 a broker cannot put that stock to work for its own account without a written agreement with the customer and collateral posted against the loan. A fully paid lending program is that agreement, signed in advance.

The loan runs on collateral rather than trust. The borrower posts at least 100 percent of the market value of the shares, and 102 percent in cash is the long-standing convention in US equities. For fully paid loans that collateral sits at a third-party custodian bank, marked to market every day: the stock rises and more collateral goes in, the stock falls and some comes back out. The borrower pays a fee for the life of the loan, the lending broker keeps a share of it, and the remainder reaches the customer whose shares went out the door.

What sets the borrow fee?

Borrow rates are negotiated broker to broker rather than printed on a public tape. The demand behind them is visible, though. Short interest, the count of shares sold short and still open, is reported twice a month; divide it by average daily volume and you get days to cover, the number of normal trading days it would take to buy those shares back. Names where a lot of stock is wanted and little is available to lend sit at one end of that range. Everything else sits in the pile the desks call general collateral.

At each name's most recent settlement date, MPT carried 22.89 days to cover, against 2.85 for MSFT at the far end of the panel. The fee spreads out the same way the demand does. General collateral is quoted in fractions of a percent a year, while a genuinely scarce borrow can be quoted in the tens of percent. The most shorted stocks ranks the crowded end of that range, and what short interest measures covers how the twice-monthly report is assembled.

The fee is quoted the way interest is quoted: an annual percentage rate on the market value of the loan, accrued daily. Take a hypothetical $10,000 of stock on loan at 0.30 percent a year. That accrues about 8 cents a day, close to $30 over a full year, before the program's split. The same position on a name quoted at 30 percent accrues about $8 a day. Identical shares in an identical account, with a hundredfold difference in what the loan pays.

Can loaned shares be recalled?

Yes, and the demand that sets the rate shifts from one report to the next, which makes a recall routine rather than exceptional. The panel below tracks days to cover for two large dividend payers across every settlement date of the past two years.

SELECT
    toString(settlement_date)                      AS as_of_date,
    formatDateTime(settlement_date, '%b %e, %Y')   AS as_of_label,
    round(maxIf(days_to_cover, ticker = 'KO'), 2)  AS ko_days_to_cover,
    round(maxIf(days_to_cover, ticker = 'XOM'), 2) AS xom_days_to_cover
FROM global_markets.stocks_short_interest
WHERE ticker IN ('KO', 'XOM')
  AND settlement_date >= today() - 730
GROUP BY settlement_date
HAVING countIf(ticker = 'KO') > 0
   AND countIf(ticker = 'XOM') > 0
ORDER BY settlement_date

Between Aug 15, 2024 and Jul 15, 2026, KO moved from 2.43 to 2.95 days to cover, with XOM finishing the window at 2.94. A loan struck against demand that travels like that is open-ended by design. The borrower returns the shares once the short is covered, and the lending broker can recall them at any point. Lending never blocks a sale either: selling the stock closes the loan inside the same transaction, and the fee stops accruing that day.

Short interest is the loan book, short volume is the flow

Fees accrue on shares still out on loan, not on trades that happened to be marked short. Daily short volume counts sell orders flagged short as they print, including the many opened and closed inside the same session. Short interest counts what remains open at the settlement date. A stock can show a high short-marked share of volume every single day and still carry a thin standing loan book.

SELECT
    toString(date)                                        AS session_date,
    formatDateTime(date, '%b %e')                         AS session_label,
    round(100 * max(short_volume) / max(total_volume), 1) AS short_volume_pct
FROM global_markets.stocks_short_volume
WHERE ticker = 'KO'
  AND date >= today() - 120
GROUP BY date
HAVING max(total_volume) > 0
ORDER BY date

Across the last 68 sessions, the short-marked share of reported KO volume finished at 30.9 percent on Aug 7. That daily line travels far more than the loan book underneath it. Short interest versus short volume takes the two measurements apart.

What does the lender give up?

Four things change while the shares are out.

• The vote goes with the shares. They were delivered to a buyer who now holds the record position, and only a holder of record votes at the annual meeting. Recalling the shares ahead of the record date is the way back.
• SIPC coverage does not apply to the loaned position. Collateral stands in its place: cash held at a third-party custodian and marked to market every day, at a value above the stock itself.
• A dividend paid during the loan arrives as a substitute payment rather than a dividend, and its tax character changes with it.
• The loan has no fixed term. It can be recalled or returned on any day, and the rate can be renegotiated as demand moves.

How are dividends handled on loaned shares?

The buyer at the other end of the short sale holds the record position, so the company's dividend goes there. Only one holder of record can receive it. The lender is paid the same cash amount by the broker instead, on the same date, as a payment in lieu of dividend. The economics match. The tax treatment does not. A substitute payment is not a dividend at all, so it lands as ordinary income rather than qualifying for the lower dividend rate. Payment in lieu of dividends shows how that arrives at tax time.

Qualified treatment carries its own holding-period test in any case: more than 60 days held inside the 121-day window centered on the ex-dividend date, which the ex-dividend date explainer sets out. A loaned share fails on separate ground, since what arrives is not a dividend to qualify in the first place. The panel below counts how often the question comes up across eight large payers.

SELECT
    ticker,
    count()                    AS payment_count,
    round(sum(cash_amount), 2) AS cash_per_share
FROM
(
    SELECT
        ticker,
        id,
        any(cash_amount) AS cash_amount
    FROM global_markets.stocks_dividends
    WHERE ticker IN ('AAPL', 'MSFT', 'JNJ', 'KO', 'XOM', 'PG', 'CVX', 'PEP')
      AND ex_dividend_date >= today() - 365
      AND ex_dividend_date <  today()
    GROUP BY ticker, id
)
GROUP BY ticker
ORDER BY cash_per_share DESC

CVX distributed $6.98 a share across 4 payments over the trailing year. Every one of those ex-dividend dates is a date on which an open loan would have turned a qualified dividend into ordinary income. All 8 names in the panel pay on a quarterly cadence, so a position lent out for a full year meets roughly four of them.

FAQ

Does lending my shares stop me from selling them?

No. A sale closes the loan as part of the same transaction, with no lockup and no notice period. Lending changes the character of what you receive along the way, not your ability to trade the position.

Do I still get dividends on shares that are on loan?

You receive the same cash amount, but it arrives as a payment in lieu of dividend rather than as the dividend itself. That substitute payment is taxed as ordinary income, so a dividend that would have been qualified is not qualified while the shares are out.

Is loaned stock protected if the broker fails?

SIPC coverage does not extend to the loaned position. Collateral takes over that job: cash of at least 100 percent of market value, 102 percent by convention, held at a third-party custodian and marked to market daily.

Why do some stocks pay far more to lend than others?

Lending rates track scarcity. Where many shares are wanted and few are available to lend, the rate climbs; a name with ample lendable supply sits in general collateral and pays a fraction of a percent a year. The demand panels above show the visible half of that balance.

Every panel here ships with the SQL that produced it, so you can open one and see exactly how the number was counted. To check how crowded the borrow looks on a name you already hold, ask the question in plain English on the Strasmore terminal.
