What is a margin call in a stock loan?

Lenders mark pledged securities to market on a defined cadence. When the ratio of loan balance to risk-adjusted collateral value exceeds a contractual limit, you enter a remediation window. The lender is protecting recovery value in a hypothetical liquidation—not passing judgment on your favorite stock. Understanding how lenders value collateral helps you anticipate calls before they arrive.

You may receive a written notice with the shortfall amount and options to cure: post cash, add securities, substitute eligible collateral if allowed, or repay part of the loan. Some agreements specify business-day timelines; others are less forgiving in stress. If you disagree with a mark, dispute processes exist—but while you argue, clocks may still run. Keep custodian contacts handy; operational delays are a common reason cures fail.

Retail margin lives inside broker rulebooks and house margin grids. Specialty stock loans may use bespoke covenants tied to your portfolio mix. Compare product mechanics on stock loans and review SBLOC concepts if you are also considering wealth-platform lines.

Ignoring a maintenance notice can cascade into default and enforcement. Overconfidence after a long bull market causes borrowers to run too hot on LTV. Plan for gaps, halts, and currency swings if collateral is denominated differently than the loan.
