Wealth Lending by Geography
The 50% figure most people associate with margin lending is a U.S. rule, not a global one. Here is how the regulatory shape, not just the numbers, actually differs across five jurisdictions.
| Jurisdiction | Common term | Primary regulatory framework | Advance-rate approach |
|---|---|---|---|
| United States | SBL, SBLOC, PAL, LAL | Regulation T (brokers) and Regulation U (banks); FINRA Rule 4210 for margin maintenance | 50% statutory cap on purpose credit; no federal cap on non-purpose credit, which is where most SBL lending sits |
| Switzerland | Lombard lending | Bank-by-bank risk policy; no single statutory advance-rate cap identified in this research | Reported ranges vary by asset class (e.g. roughly 50%-80% at Julius Baer, by asset class); individually negotiated per client |
| United Kingdom | Lombard loan | Largely outside the FCA-regulated mortgage perimeter (not secured on UK residential property); FCA still requires affordability/suitability review | Bank-by-bank; no single statutory cap identified in this research |
| Hong Kong | Lombard loan | Split regulation: HKMA (banking, under the Banking Ordinance) and SFC (securities, under the Securities and Futures Ordinance), coordinating via MOU | Bank-by-bank; diversified portfolios reported to achieve higher advance rates and lower margin-call likelihood than concentrated ones, consistent with the mechanism seen in every jurisdiction covered here |
| India | Loan against securities (LAS) | RBI-regulated directly; a draft circular (Oct. 25, 2025) proposed materially higher limits | Statutory LTV ceilings: proposed increase from 50% to 60% on shares, 50% to 75% on debt mutual funds (draft, not yet confirmed finalized) |
The pattern underneath the differences
Only one jurisdiction covered here, India, regulates the loan-to-value ratio on securities-based lending directly, with a statutory ceiling. The United States regulates a narrower slice, purpose credit specifically, leaving the much larger non-purpose SBL market without a federal cap at all (see this site's Regulation U guide for why that distinction exists). Switzerland, the UK, and Hong Kong take a lighter statutory touch still: advance rates are set bank by bank, with regulators focused more on suitability, conduct, and prudential soundness than a specific published ceiling.
This is not evidence that any one jurisdiction is more or less “safe” for a borrower. It means the actual protection a borrower has, a statutory ceiling, a suitability requirement, or simply a bank's own competitive discipline, comes from a genuinely different source depending on where the loan is booked.
What this page does not yet cover
Singapore-specific regulatory detail (the Monetary Authority of Singapore's framework for Lombard-style lending) was not located to this vertical's verification standard in this research pass and is deliberately omitted rather than merged into the Hong Kong row or guessed at. The same applies to numeric tax-treatment and dominant-use-case comparisons across all five jurisdictions, which the original scope for this page called for but this pass could not source to a defensible standard, jurisdiction by jurisdiction, within the time available. Both are flagged as the next research pass for this page, not silently dropped.
Frequently asked questions
Is the 50% loan-value cap from U.S. Regulation U a global standard?
No. It is specific to purpose credit under U.S. Regulation U. India's RBI regulates loan-to-value directly for loans against shares (a proposed increase from 50% to 60% was under consideration as of a late-2025 draft circular), while Switzerland, the UK, and Hong Kong largely leave Lombard lending's advance rates to bank-by-bank risk policy rather than a single statutory cap on non-purpose credit.
Is Lombard lending regulated the same way everywhere?
No, and the regulatory architecture itself differs, not just the numbers. In the UK, most Lombard facilities fall outside the regulated mortgage perimeter (since they are not secured on UK residential property), though the FCA still requires affordability and suitability assessments. In Hong Kong, banking and securities activity are split between two separate regulators, the HKMA and the SFC, that coordinate under a formal agreement. In the U.S., the analogous framework is Regulation T and Regulation U, run by the Federal Reserve. Each jurisdiction built a different regulatory shape around the same underlying product.
Which jurisdiction has the most standardized wealth-lending rules?
The U.S., by a meaningful margin, at least for margin lending specifically: Regulation T's 50% initial margin and FINRA Rule 4210's 25% maintenance floor are both codified, publicly documented rules that apply uniformly across FINRA member firms. Non-purpose SBL lending in the U.S. is comparatively less standardized (no federal maintenance-margin floor), which is closer to the pattern seen in Lombard lending in Switzerland, the UK, and Hong Kong, where terms are set bank by bank.
Important information
This page is informational only and is not investment, tax, or legal advice, and is not a recommendation to borrow or a statement that any specific lender is best for you. Interest on a securities-based, Lombard, or similar loan may or may not be tax-deductible depending on how the proceeds are used; consult a qualified tax advisor about your own situation. Borrowing against a portfolio carries margin-call risk: if pledged collateral loses value, a lender can require additional collateral or repayment on short notice, potentially forcing a sale at a loss. Rates are typically variable and can rise. Figures labeled "published" come from a lender's own rate disclosures as of the date shown; figures labeled "estimated" are ranges derived from a limited sample and are not a quote. SwitchWize receives no compensation from any lender named on this page.
