Concept
Lombard lending is a loan secured by a liquid portfolio of securities. The client pledges stocks, bonds, or funds and receives a credit line without selling the assets: the securities stay in their ownership, dividends and coupons keep accruing, and cash lands in the account. The bank holds the portfolio as collateral and sees its market value at all times, so the limit is decided quickly, without the lengthy underwriting and appraisal of a mortgage. The name itself comes from the Lombard merchants of northern Italy, who lent against movable collateral back in the Middle Ages.
Origins
Modern lombard lending grew out of private banking practice: for a wealthy client with a large portfolio, it is more convenient to borrow against it than to sell the assets and trigger capital gains tax. The classic providers are the Swiss and Luxembourg banks, where lending against pledged securities became a separate line of business long ago, with its own limits and risk models. Over time the range of eligible collateral has widened: today banks take not only stocks and bonds but also cash balances, money market funds, and even life insurance policies with an accumulated cash value.
How the Limit Is Calculated
The limit is calculated from the market value of the portfolio minus a haircut — a discount for risk. The bank assigns each asset class its own advance rate, or loan-to-value (LTV): the more liquid and stable the security, the more can be borrowed against it.
| Asset class | Advance rate (LTV) |
|---|---|
| High-quality government bonds | 80–95 percent |
| Investment-grade corporate bonds | 70–85 percent |
| Blue-chip stocks and broad index funds | 50–70 percent |
| Individual volatile stocks | 0–50 percent |
| Concentrated positions, illiquid holdings, complex structured notes | Discounted harder or not accepted at all |
In Switzerland, FINMA explicitly expects banks to set haircuts by asset type in advance, so there is little room for discretion. Across a mixed portfolio the resulting limit usually settles around 50–70 percent and is arranged as a revolving credit line or a fixed-term tranche.
Rate
The rate on a lombard loan floats: a benchmark plus the bank's margin. The loan is secured by collateral, so the margin is small and the resulting rate comes out lower than on unsecured credit. The benchmark depends on the currency of the loan, and by mid-2026 benchmark levels diverge markedly.
| Currency | Benchmark | Level |
|---|---|---|
| Dollar | SOFR | around 3.6 percent |
| Euro | Three-month EURIBOR | around 2 percent |
| Swiss franc | SARON | 0 percent (SNB rate since summer 2025) |
That makes a franc-denominated lombard the cheapest of the three. The downside of a floating rate is obvious: when central banks raise rates, servicing costs rise in lockstep across the whole line, and the buffer to a margin call melts away.
Use Cases
A lombard loan is taken to raise cash without breaking an investment position: to finance the purchase of property or a stake in a business, to cover a cash-flow gap ahead of a large deal, to pay a tax bill, or, less often, to add leverage and buy more assets. For family capital it is a working liquidity bridge when money is needed here and now and selling off a quality portfolio into a poor market makes no sense. A common scenario is a bridge to close a deal, which is then repaid from the proceeds or refinanced with a longer loan — for a home purchase abroad, usually a non-resident mortgage with its own LTVs, rates and document pack.
Premium financing
A separate branch of lombard lending funds the payment of a large insurance premium on unit-linked, whole-life or PPLI policies: the collateral is the policy itself with its accumulated cash value and, as a rule, an additional portfolio. The pledge mechanics are the same, but the interest-rate risk of the loan and the behaviour of the policy come on top of the portfolio's market risk, so the structure is built for a long horizon and a solid collateral buffer. The Singapore construction in full — single premium, the LTV grid, margin calls, interest deductibility through a VCC and the currency of the leverage — is set out in Universal Life in Singapore.
Loan and taxes
The appeal of a lombard loan is largely tax-driven. Taking out the loan creates no taxable event: selling shares crystallises the gain and the tax on it, whereas borrowing against the same shares leaves the position untouched. This is the basis of the well-known buy-borrow-die logic, where a wealthy owner lives for years on credit against the portfolio and never realises a profit.
The same technique is carried over to illiquid assets, where a sale costs an auction commission on top of the tax — borrowing against a collection instead of selling. For a client who has changed tax residence, the same technique helps wait out an unfavourable jurisdiction and avoid crystallising a gain too early. The precise consequences depend on the country of residence and the ownership structure, so a lombard loan is almost always built into the wider map: holding, family office, and an insurance wrapper.
Interest deductibility: a question of jurisdiction
Interest on a lombard loan rarely reduces tax by itself. In the US, the investment interest deduction under IRC §163(d) lets interest on borrowing for investment be deducted up to net investment income, and long-term gains and qualified dividends enter that base only by a special election — at the cost of their preferential rate (Form 4952). In the UK there is no deduction for private borrowing beyond a narrow list of qualifying loans. Most continental jurisdictions likewise deny it for personal borrowing, though interest is deductible at company or fund level when the borrower is corporate. Bottom line: the borrower's jurisdiction and tax wrapper change the economics of buy-borrow-die as much as the rate itself.
What to check in the contract
The terms of the credit line matter more than the advertised rate. Most lombard lines are uncommitted: the bank may revise the limit or demand repayment at its own discretion, especially in a falling market. It is worth establishing in advance the margin call triggers and whether there is a cure period — the window in which additional collateral may be posted before the bank starts selling the pledge. The currency matters: a loan in one currency against assets in another adds exchange risk on top of market risk. Cross-collateralisation deserves separate attention, where the entire portfolio at the bank becomes security for the line and the freedom to dispose of the assets narrows.
A margin call in numbers
The mechanics are best seen in figures. A $10 million blue-chip portfolio at a 60 percent advance rate supports a $6 million line; assume it is fully drawn. The market falls 20 percent: the portfolio is worth $8 million, the permitted debt is 60 percent — $4.8 million — against $6 million drawn. The shortfall is $1.2 million.
| Measure | At origination | Market −20% |
|---|---|---|
| Portfolio | $10m | $8m |
| Debt ceiling (60%) | $6m | $4.8m |
| Drawn | $6m | $6m |
| Shortfall | — | $1.2m |
There are three ways out. Post more collateral: cash closes the gap one for one ($1.2 million), while securities count after the haircut — $1.2 million / 0.6 = $2 million of the same blue chips. Partially repay — the same $1.2 million. Or let the bank sell the pledge: a cure period of 2–5 business days is typical, but on an uncommitted line, as noted above, the bank need not wait. Banks distinguish initial margin — the level at which they lend — from maintenance margin — the threshold to be maintained; the buffer between the two is the argument for not drawing the line to the ceiling: a fully drawn limit turns the first dip into a margin call.
Pledge vs title transfer: who holds title
The legal form of the security matters as much as the LTV. A classic pledge keeps title with the client: the securities sit in a segregated custody account and the bank may not use them. The alternative — title transfer, or a pledge with a right of use clause — passes title or the right of use to the bank, which may rehypothecate the securities in its own operations. The difference surfaces if the bank fails: for the re-used securities the client turns from owner into an unsecured creditor. Check the right of use clause and the rehypothecation limit (for example, no higher than the debt outstanding), along with how custody segregation and deposit protection are arranged — more in the review of Geneva private banks.
Leverage Works Both Ways
Lombard lending is an ordinary banking product, but leverage amplifies both profit and loss. With a floating rate and volatile collateral, the borrower carries a double risk: rising interest rates and falling collateral at the same time. To live off the proceeds of a lombard loan, practitioners cite a portfolio of €8–10 million to have enough buffer against a margin call.
Q/A
Is it safe to draw a Lombard line to its full limit?
No. The maximum line shows what the bank will lend against today's collateral value and haircuts, not a safe debt level. If it is fully drawn, even a modest portfolio fall or haircut change can create an immediate shortfall and trigger a margin call.
What can the bank demand after a margin call?
The borrower will usually have to post acceptable collateral, add cash or repay part of the debt; if the demand is not met, the agreement may let the bank sell pledged assets. The cure period, valuation method and any right to act without waiting depend on the particular facility.
Why match the loan currency to the collateral?
A mismatch creates currency risk on top of portfolio movements. Even if the securities do not fall in their own currency, an adverse exchange-rate move can reduce their collateral value relative to the debt and bring a margin call closer, so the currency pair and the safety buffer must be assessed together.
How does a pledge differ from a title transfer?
Under a conventional pledge title normally remains with the client; title transfer or an agreed right of use gives the bank title or permission to use the securities. That changes rehypothecation and insolvency risk, so the contract must be checked for custody segregation and reuse rights.
Can a Lombard loan be treated as permanent income?
No. The facility creates liquidity, not income: interest accrues, the debt remains and the collateral is revalued. It is more resilient with moderate drawings and a large liquidity buffer; a floating rate and a falling market together can turn a temporary drawdown into a forced sale.
