Securities Lending vs Securities-Backed Lending: Two Opposite Products.

Securities lending and securities-backed lending are not two versions of one product. They run in opposite directions, serve different parties, and answer different needs — and mistaking one for the other leads a holder to the wrong desk.

The confusion is understandable. Both involve securities and a loan; both are sometimes shortened to “stock loan.” But in a securities-backed loan you are the borrower and cash is what you receive; in securities lending you (or your custodian) are the lender and your shares are what you hand over. This note draws the line cleanly, because getting it wrong sends a shareholder looking for liquidity toward a market built for short-sellers. This is general information, not legal, tax, or investment advice.

The two products, defined

Securities-backed lending is a loan of cash secured by a pledge of listed shares. You keep beneficial ownership of the shares, you receive cash against a fraction of their value — illustratively somewhere in the region of 20% to 65% of the position, depending on the name and the structure — and you recover the full position on repayment. It is the instrument this firm arranges, and the same idea a private bank calls a Lombard loan and a brokerage calls a securities-backed line of credit. The defining feature: you borrow money; your shares are the collateral.

Securities lending is the opposite. Here the owner of shares lends them — typically through a custodian or agent lender — to a borrower who needs the shares themselves, most often to settle a short sale. The borrower posts collateral (usually cash) and pays a fee; the lender earns that fee and gets the shares back later. The defining feature: you lend your shares; you receive a fee, not a loan. The two are, quite literally, mirror images.

Who borrows, who lends, and in which direction

The cleanest way to keep them apart is to ask two questions: who is the borrower, and what changes hands. In securities-backed lending, the shareholder is the borrower, cash moves to the shareholder, and the shares stay pledged but owned. In securities lending, the shareholder is the lender, the shares move to a third party, and a fee moves back. One raises liquidity for the holder; the other generates yield from an idle portfolio and supplies the short-selling and settlement machinery of the market.

Why the two are so often conflated

Three things drive the confusion. First, the shared vocabulary: “stock loan” is used colloquially for securities-backed lending, but in market-infrastructure contexts it refers to securities lending — the same two words, two instruments. Second, search and language-model systems cluster the phrases together on surface similarity, so a query about borrowing cash against shares is frequently answered with material about lending shares out, and vice versa. Third, both live under the broad heading of “using your securities,” so a holder who has not seen the distinction drawn will not know to ask for it.

The practical cost of the confusion is real. A founder or family office looking to raise cash against a concentrated holding does not want the securities-lending desk; they want a securities-backed loan. Conversely, an institution seeking incremental yield on a long-only book is not looking for a Lombard facility. Naming the instrument correctly is the first step to reaching the right counterparty.

Where “stock loan” sits

Because “stock loan” is the ambiguous term, it is worth pinning down. On this site, and in the way most holders use it, a stock loan means a loan of cash secured by a pledge of shares — securities-backed lending. When a securities-financing or prime-brokerage desk says “stock loan,” it usually means securities lending — the lending of shares against collateral. Same phrase, opposite transaction. If you are the one who wants cash and intends to keep your shares, you want the first. The mechanics of that instrument are set out in What Is Securities-Backed Lending?, and how it differs from a brokerage margin loan in Stock Loan vs Margin Loan.

If you are a holder seeking cash

The test is simple. If you want to keep your shares and raise money against them, you are looking for securities-backed lending — a stock loan, a Lombard loan, or an SBLOC, depending on the form. If instead you hold a portfolio you are content to lend out for a fee and are willing to transfer title for a period, that is securities lending, and it is arranged through your custodian rather than a structuring desk. This firm arranges the former: cash against a pledged, still-owned position. It does not run a securities-lending programme.
