A stock loan and a margin loan are both secured by securities, but they are built for different jobs. A margin loan is a brokerage facility used chiefly to buy more securities, secured against a diversified portfolio under standardised maintenance rules. A stock loan is purpose-built financing against a specific, often concentrated, IDX-listed shareholding — arranged to tolerate exactly the concentration a margin desk penalises. For a founder or major shareholder borrowing against a single large position, the stock loan is usually the right instrument.
The distinction in one line
- Margin loan — leverage to buy more, against a diversified portfolio, on standard terms.
- Stock loan — liquidity against a concentrated strategic stake, on negotiated terms.
Different purposes
The clearest difference is intent. A margin loan exists to amplify a trading strategy — you borrow against your portfolio to buy more securities, taking on leverage. A stock loan exists to extract liquidity from a position you already hold and intend to keep, without selling it and without buying more. One is about growing exposure; the other is about monetising existing exposure while preserving it.
Different collateral
A margin facility is designed around a diversified portfolio. Its maintenance rules assume that no single name dominates, and they react badly when one does — a large single-stock position is typically given a punitive margin value or excluded outright. A stock loan does the opposite: it is built specifically for a concentrated, single-name holding, often a founder's or family's controlling stake, and is structured to accommodate that concentration rather than penalise it.
| Feature | Stock loan | Margin loan |
|---|---|---|
| Collateral | A specific, often single-name listed holding | A diversified brokerage portfolio |
| Who lends | A specialist arranger or private lender | A securities firm or broker |
| Typical use | Liquidity against a strategic stake | Buying additional securities (leverage) |
| Terms | Negotiated and structured per position | Standardised across accounts |
| Recourse / margin | Negotiated; tailored mechanics | Standard maintenance margin and calls |
| Concentration tolerance | High — concentration is the norm | Low — penalised or excluded |
Different mechanics
Margin terms are standardised: the same maintenance margin and the same call mechanics apply across every account, set by the broker. A stock loan is negotiated to the position — the LTV, the tenor, the recourse profile, and the margin and top-up mechanics are all agreed up front and written for your specific holding. That tailoring is what lets a stock loan carry a concentrated position safely, where a margin facility would either refuse it or call it at the first wobble.
When each fits
If you are an active investor running a diversified book and want leverage to trade, a margin loan is the natural tool. If you are a founder, a controlling shareholder, or a family holding a large single IDX-listed position and you want liquidity without selling, buying more, or being forced out by a standardised margin call, a stock loan is built for you. The two are not really competitors — they answer different questions. For the instrument in full, see our stock loans overview and the explainer on what an Indonesia stock loan is.
