Margin calls: when leverage demands payment

Borrow money to trade and you've added a second party to every position: the lender. When things go against you, that lender can demand cash — right when you have the least appetite to provide it. That's a margin call, and it's one of the sharper edges of leverage.

How it works

When you trade on margin, you're borrowing against your account to control a larger position. Brokers require you to maintain a minimum equity level (maintenance margin). If your positions lose enough value that your equity falls below that line, you get a margin call: add cash or liquidate positions to restore the minimum.

If you don't act, the broker can — and will — sell your positions for you, on their timeline, not yours.

Why it's so punishing

The cruelty of margin calls is their timing. They arrive during declines, because that's when your equity drops below the threshold. So you're forced to either:

• Add cash precisely when you may be least able or willing, or
• Sell into weakness, locking in losses at the bottom — the exact opposite of what you'd choose.

It can become a spiral: forced selling pushes prices lower, triggering more calls. Leverage that felt fine on the way up turns into forced, loss-realizing selling on the way down.

Respecting it

• Don't run leverage so high that a normal pullback triggers a call. Leave room for ordinary volatility.
• Know your maintenance requirements before you use margin, not after.
• Remember the lender's interests aren't yours. Their job is to protect their loan, even if that means liquidating you at the worst moment.

A margin call is leverage sending the bill. The way to avoid the worst of it is the same as always: keep leverage modest enough to survive the bad days that will come.
