Why This Matters
The risks most firms won't explain clearly
Securities-backed lending is marketed as a sophisticated wealth-management tool — and it can be, when used correctly. But it is fundamentally a leveraged strategy. And leverage always cuts both ways.
In 2022, the S&P 500 fell 25% from peak to trough. FINRA margin debt data shows a $237 billion decline in outstanding balances — from $844 billion (October 2021 peak) to $607 billion (December 2022). That contraction represents a combination of forced liquidations, margin calls, and panic-driven voluntary deleveraging.
"The worst time to face a margin call is during a market crash — which is exactly when margin calls happen. Forced liquidation locks in losses at the bottom and may trigger capital gains taxes on shares sold at depressed prices."
Market Decline Risk
What happens when your collateral loses value
When you borrow against a portfolio, the lender monitors your loan-to-value (LTV) ratio continuously. If your portfolio declines in value while your loan balance stays the same, your LTV rises — potentially triggering a maintenance call.
| Market Decline | Impact on $500K Loan / $1M Portfolio |
|---|---|
| 0% (starting position) | LTV = 50% — within normal range |
| −10% | LTV = 56% — approaching caution zone |
| −20% | LTV = 63% — likely maintenance warning |
| −30% | LTV = 71% — probable margin call |
| −40% | LTV = 83% — forced liquidation likely |
| −50% | LTV = 100% — loan equals portfolio value |
Most lenders require maintenance LTV below 65–75%, depending on the collateral type. Once you breach that threshold, you typically have 3–5 business days to respond — by depositing additional cash, adding collateral, or repaying part of the loan. If you cannot respond, the lender sells your securities.
No Grace Period Guaranteed: Under FINRA rules, broker-dealers can liquidate pledged securities to meet margin calls without prior notice. While most lenders provide a courtesy window, they are not legally required to do so. In extreme market conditions (flash crashes, gap-downs), liquidation may occur automatically.
Concentration Risk
Why single-stock collateral is especially dangerous
A diversified portfolio might decline 25–30% in a severe bear market. A single stock can decline 50–80% — or effectively go to zero. The Archegos Capital collapse in March 2021 demonstrated this vividly: concentrated positions in a handful of stocks resulted in $10+ billion in losses across prime brokers when margin calls cascaded.
Single Stock vs Diversified ETF: Crash Scenarios
Concentrated Single Stock
−60%
Possible single-stock decline in a year
Meta fell 64% in 2022. Netflix fell 51%. Individual stocks routinely experience drawdowns that would destroy any borrowing position at standard advance rates.
Diversified S&P 500 ETF
−25%
Worst S&P 500 decline (2022)
Even in the worst modern bear markets, diversified indices have never approached the catastrophic single-day or single-year declines common in individual stocks.
Key Implication: This is why lenders offer 65–80% advance rates on diversified ETFs but only 40–60% on concentrated single-stock positions. The lower advance rate is not conservative enough protection in extreme scenarios — it simply means the margin call comes slightly later.
If you're borrowing against a concentrated tech stock — Alphabet, Meta, Nvidia, Apple, Microsoft — you face sector-specific risks that don't apply to a diversified portfolio. An antitrust ruling, earnings miss, or AI competition shift can trigger a 30%+ decline in days. Your margin cushion can evaporate before you have time to respond.
Rate Risk
When variable rates turn against you
Most securities-backed credit lines carry variable interest rates tied to SOFR or a similar benchmark. Between 2021 and 2023, SOFR rose from near-zero to over 5% — an extraordinary increase that multiplied borrowing costs for anyone with outstanding balances.
| Year | Approximate Cost on $500K Balance |
|---|---|
| 2021 (SOFR ~0.05%) | $10,000–$15,000/year |
| 2022 (SOFR ~3.5%) | $27,500–$32,500/year |
| 2023 (SOFR ~5.3%) | $36,500–$41,500/year |
| 2026 (SOFR ~3.6%) | $27,500–$33,000/year |
An investor who borrowed $500,000 in 2021 expecting $10,000/year in interest suddenly faced $40,000/year by 2023 — a 4x increase. If that investor's cash flow couldn't absorb the higher cost, they faced a choice: repay the loan (possibly by selling stock at a loss) or continue paying far more than planned.
Variable-rate risk is particularly insidious because rate hikes often coincide with market declines — meaning your borrowing cost increases at exactly the moment your collateral value decreases. This double pressure can force liquidation at the worst possible time.

Forced Liquidation
How lenders protect themselves — at your expense
When a maintenance call is not met, the lender liquidates your pledged securities to reduce the loan balance. This is not a negotiation — it is a contractual right the lender exercises to protect their capital. Key facts:
No advance notice required
Under FINRA rules, broker-dealers are not obligated to issue a margin call before liquidating. Courtesy calls are common but not guaranteed — especially in fast-moving markets.
Lender chooses what to sell
You typically cannot choose which securities are liquidated. The lender may sell your most appreciated positions — triggering the maximum possible tax bill at the worst possible time.
Liquidation IS a taxable event
A forced sale triggers capital gains taxes just like a voluntary sale. If you borrowed to avoid taxes, a forced liquidation defeats the entire purpose — and you owe taxes on top of having sold at a depressed price.
You may still owe money
If the portfolio value has dropped below the loan balance (in extreme scenarios), selling all pledged securities may not cover the debt. You could owe a deficiency balance.
This is the nightmare scenario: market crashes, your stock is sold at the bottom, you owe capital gains taxes on the forced sale, you lose the shares permanently, and you may still have outstanding loan balance. It's rare — but not impossible, and it happens during exactly the kind of market dislocation that makes recovery difficult.
Risk Management
How to protect yourself if you borrow
If you choose to use securities-backed lending, these practices significantly reduce your risk:
Borrow conservatively: target 30–40% LTV maximum
Even if the lender offers 70% advance, borrowing only 30–40% gives you a 50%+ market decline cushion before hitting maintenance levels.
Maintain cash reserves equal to 6–12 months of interest
Ensures you can service the loan even if your income is disrupted or rates spike unexpectedly.
Use diversified collateral where possible
A portfolio of 20+ stocks or broad-market ETFs is far less likely to trigger a margin call than a single concentrated position.
Know your exact maintenance requirement
Ask the lender: at what portfolio value will I receive a margin call? Calculate what market decline percentage triggers it. If that number is less than 30%, you're too leveraged.
Have a pre-planned response to a margin call
Decide in advance: will you deposit additional collateral, make a partial repayment, or allow selective liquidation? Don't make this decision under pressure.
Monitor monthly — set price alerts
Set alerts at 10%, 20%, and 30% declines from your starting collateral value. Each alert is a decision point to reduce exposure before a call is forced.
Never use loan proceeds to buy more risk assets
Borrowing against stocks to buy more stocks (or crypto, or options) creates layered leverage that can unwind catastrophically. Keep borrowed funds in productive, non-speculative uses.
The Embark Alternative
Income from concentrated stock — without leverage
Every risk on this page exists because of one thing: leverage. You're borrowing against a volatile asset and hoping it doesn't decline faster than your ability to respond. Embark's approach eliminates leverage from the equation entirely.
The Embark Approach
No Margin Calls — Ever
You're not borrowing. There's no debt, no maintenance requirement, no forced liquidation trigger.
10%+ Targeted Annual Income
Your stock generates yield through institutional options strategies — income you keep, not interest you pay.
No Variable Rate Exposure
Your income isn't affected by SOFR movements. No surprise cost increases.
Tax-Deferred Entry
§721 in-kind contribution avoids the capital gains trigger — same benefit as borrowing, without the debt.
If your goal is income from a concentrated stock position, Embark's §721 SPV delivers that income without the structural risks of borrowing. You keep upside exposure, avoid forced liquidation, and generate yield — all while deferring capital gains taxes through a partnership contribution rather than a pledging arrangement.
FAQ
Risk questions answered directly
Can I lose my stocks with a securities-backed loan?
Yes. If your collateral value drops below the maintenance requirement and you cannot meet the margin call (by depositing cash or additional securities), the lender can and will sell your pledged shares — potentially without advance notice.
What is a margin call?
A margin call (or maintenance call) is a demand from the lender to restore your loan-to-value ratio to acceptable levels. You typically have 3–5 business days to respond by depositing additional collateral, making a cash payment, or allowing partial liquidation — but this grace period is not guaranteed.
What happens if my stock-backed loan collateral falls?
Your loan-to-value ratio increases. If it breaches the maintenance threshold (typically 65–75% depending on lender and collateral type), you'll receive a margin call. Failure to cure the call results in forced liquidation of your pledged securities.
Can a lender sell my shares without asking?
Yes. Under FINRA rules, broker-dealers have the contractual and regulatory right to liquidate pledged securities without prior notice to cure a maintenance deficiency. Most lenders provide courtesy notification, but they are not required to do so.
How do I avoid a margin call?
Borrow conservatively (30–40% of portfolio value maximum), use diversified collateral, maintain substantial cash reserves, monitor your LTV ratio weekly, and have a pre-planned response strategy before a call ever occurs.
