Margin Requirements, Calls, and Borrow Costs

Margin requirements, calls, and borrow costs determine whether leveraged exposure can remain open and what carrying or close-out costs can arise.

Margin Call covers initial and maintenance requirements, equity percentages, call thresholds, deficiency calculations, broker liquidation rights, and the difference between adding cash and selling positions.

Borrow Fee covers the distinct cost of borrowing securities for a short sale, including changing rates, hard-to-borrow status, lender recalls, distribution obligations, and forced-cover risk.

Use Margin for the broader securities, futures, derivatives, initial, maintenance, house, and portfolio-margin framework. Use Margin Account for broker loans, margin debt, buying power, interest, and collateral eligibility.

Evidence to Check

• Current position, market value, debit, equity, and applicable requirement.
• Product, account, broker, exchange, clearing, and house-margin methodology.
• Borrow rate, quantity, availability, recall terms, and distribution calendar.
• Call notice, response permitted, transfer timing, and liquidation record.
• Interest, fees, spread, tax effects, and post-close reconciliation.
