What you'll learn

If you own a large position in one or more stocks, lending your shares can be an easy way to earn passive income from your idle investments. Stock lending programs give you cash payments every time your shares are lent out, which you can reinvest, put toward diversification, or spend on other expenses. You won’t have to sell any shares, so you can participate without disrupting your long-term investment strategy.

If you’re intrigued, you’re in the right place. Within the next few minutes, we’ll explain the nuts and bolts of how stock lending works, the major benefits you can expect, and a few drawbacks to watch out for.

Almost all brokerage firms do this one way or another. However, you might not have realized that your shares are being lent out (or received any income from them). We want to make sure you can make the most of the stock you’re holding.

What is stock lending?

Stock lending is when another investor temporarily rents some stock from you. They borrow your shares and pay you a fee for lending to them. There’s no term or lockup, and the lending rate is essentially renegotiated each day based on the market demand.

Stock lending is a common practice that’s been available in the US in some form for at least 100 years – and possibly a lot longer.

You don’t sell your stock to participate, so no capital gains taxes are triggered. You merely have a little more money in your pocket from the idle shares in your portfolio. Stock lending is also known as “securities lending,” as the practice is common across stocks, bonds, and fund shares.

The only major requirement on your end is that the stock you loan must be “fully paid,” which means that you fully own the stock yourself – not purchased on margin or borrowed.

How does stock lending really work, though?

We now understand your experience when you loan out a stock, but there’s a lot more going on behind the scenes. The investor on the other side of the loan is usually a large financial institution, and a third-party lending agent, like a brokerage or custodian bank, facilitates the transaction.

Before they receive your stock, the borrower puts up collateral in cash or treasury bills – typically 102% of the value of shares borrowed. This collateral serves as protection in case the shares are not returned. Each day, the collateral requirement is re-evaluated (or “marked-to-market” in investment parlance) as the stock’s price fluctuates. This requirement minimizes default risk.

Your shares are then lent to the borrower for a set period, with the contract reset daily. Rates vary based on demand for the stock and how difficult the shares are to borrow. Hard-to-borrow stocks typically earn higher fees. Rates can vary from a few basis points to 5% or more– we’ll take a closer look at the rates you receive later in this piece.

You maintain full ownership rights on the shares you loan out. Any dividends the borrower receives are forwarded to you (and treated as ordinary income by the tax code). You can also sell at any time, at which point the stock is recalled and the loan canceled. When the term of the loan is complete, you’ll receive the same number of shares that you lent initially. Any returns or losses those stocks experience over the course of the loan will still be yours.

What does the borrower do with your stock?

Famous publisher William Feather once said: “One of the funny things about the stock market is that every time one person buys, another sells, and both think they are astute.” Stock lending helps facilitate some of the complex transactions these astute borrowers hope to carry out. Specifically, borrowers might be:

  1. Short selling: When borrowers want to bet that the price of a stock will decline, they sell the borrowed shares and then buy them back later to return to the lender. This allows them to profit if the stock price declines.
  2. Hedging: Borrowed stock can be used by large financial firms to offset market exposure when they hold certain stocks as collateral. By negating their “long” exposure, they can remain market-neutral.
  3. Covering failed trades: If a brokerage or trader fails to deliver shares for a settlement, they may borrow stock to fulfill their delivery obligation.
  4. Liquidity in the markets: The increased availability of shares from lending can be used by market makers to facilitate a liquid marketplace for trading. 

Some of these transactions may involve significant risk – which is why regulators require borrowers to put down cash collateral of 102% as part of the loan.

How Much Extra Income Can You Earn?

The amount of income you generate from a stock loan depends on two primary factors:

  1. Lending rates: The loan rate is dynamic and based on how hard the stock is to borrow. If there isn’t enough supply of a stock investors want to borrow, rates go up. If the stock is well-supplied, the rates go down. Typical annualized rates can range from 0.2% to 5%, and it is not uncommon to see heavily shorted stocks reach 100%+.
  2. The interest rate for the borrower’s collateral: The collateral is typically invested in low-risk liquid investments like treasury bills, which yield additional income.

To calculate potential earnings from stock lending, just add the lending rate to the effective federal funds rate, then multiply that number by the value of the securities you’re contributing. The result approximates how much you might earn in a year. 

Stock lending rates can range from a few basis points for easy-to-borrow stocks to over 5% per year for hard-to-borrow stocks. Typically, growth stocks attract more speculators, resulting in higher fees. For example, in 2022, LCID generated the highest revenue, consistently trading at a premium of 5% or more throughout the year. VISA, TSLA, UBER, LYFT, and UPST have been among the best stocks for stock lending in recent years.

You should also keep in mind that the third-party intermediaries who facilitate the transaction charge a commission, leaving you with a split of the revenue generated.

How much can you earn overall?

Let’s look at an example to see how it all adds up.

As an example, imagine you held a $100,000 stock position, which had an annualized loan rate of 2%. Fees are usually paid monthly, so that would mean about $167 a month in income if the lending rate stayed the same. In fall 2023, short term interest rates are close to 5%, which means you’d receive another $416 or so from interest on the borrower’s collateral – or $583 in total monthly income.

And remember that you still technically own the stock, so you’re also benefiting from any appreciation it experiences while on loan.

Hard-to-borrow stocks can earn even higher yields – sometimes two to three times as much as the stocks in this example.

Pros and cons of stock lending

Stock lending gives you passive income from something you already own. In exchange, you take on some risks and limitations. Here’s a closer look at those pros and cons:

The benefits:

Stock lending offers quite a few ways for you to take advantage of your significant equity holdings:

Earn passive income on existing stock positions

Stock lending provides passive income on idle assets you were planning to hold. It can act as a wind at your back by improving annual returns.

High fees for hard-to-borrow growth stocks

Lending rates can exceed 5% for stocks that are in demand.

There’s no change in ownership

You maintain voting rights and can recall the shares whenever you’d like.

Receive dividends as usual

Any dividends paid on lent stocks are passed through to you by the borrower. Note that these are manufactured dividends, not qualified dividends, for tax purposes.

Easily recall shares or sell lent stocks

You can cancel an existing loan or sell stocks you’ve lent out at any time.

No day-to-day management needed

Once you’ve opted in, stock lending programs run on auto-pilot, with shares lent out as demand arises. The incremental income just starts accruing.

Risks and downsides

All investments carry risks, including the loss of principal. Here are some of the potential downsides you may encounter:

Loss of SIPC protection

While stocks are on loan, they are not covered by the federal insurance program that protects investors against the failure of their brokerage.

Possibility of not finding borrowers for your shares

If nobody borrows your shares, you earn no additional income.

Borrower default risk

You could lose principal if the borrower becomes insolvent. After the Great Financial Crisis, the SEC instituted tighter collateral requirements of at least 102% of shares borrowed, though it is still possible that the collateral isn’t enough to replace the borrowed stock, and the borrower declares insolvency.

Reinvestment risks on the cash collateral

Lenders usually opt for safe, conservative, and highly liquid investment options (like short-term treasury bills) for the collateral that’s received, but all investments bear some risk.

So, is stock lending a good idea? And is it safe?

Stock lending can be a safe and productive investment strategy when done carefully and with a clear understanding of the associated risks. However, like any investment activity, it carries some potential risks that investors should be aware of. 

Stock lending is a good fit for long-term investors who do not need intraday liquidity and have a moderately optimistic view of their holdings. The added income simply enhances your overall return without needing to change your core positions.

If you look at the pros and cons in the previous section – or talk them through with an investment advisor – and feel like the upside outweighs the risk, it can be a compelling strategy to include in your portfolio.

Choosing a brokerage for stock lending

If you decide you’re ready to generate extra income by lending out your idling shares, the next step is finding the right provider. Here are key factors to evaluate:

  • Fee splits
    Look for platforms that pass through most of the lending income to you rather than taking a large cut themselves. As of Nov 2023, most brokerages still pass zero stock lending revenue to clients.
  • Security and transparency
    Ensure robust safeguards around collateral management, borrower vetting, and reinvestment of collateral.
  • Smooth experience
    Look for an easy sign-up process, clear reporting, and the ability to turn stock lending on and off.

Some brokerages currently offer stock lending programs. If you evaluate providers using these three factors, it can help you make an informed decision.
