Key point: A stock-backed loan combines market-price risk with debt. Maintenance and call thresholds must come from your actual contract.
A call usually requires restoring the required buffer
The lender may ask for cash, additional eligible collateral, or partial repayment. Timing and target ratios depend on the contract.
Failure to act can lead to collateral disposal
Current securities-finance rules contain call and disposal procedures, and TDCC pledge procedures explain how a pledgee can enforce rights after a matured debt remains unpaid.
Selling the collateral may not eliminate the debt
If disposal proceeds do not cover principal, interest, and costs, the borrower may still owe the shortfall under the contract.
Fast markets are the real danger
Gaps and limit-down trading can move collateral through several thresholds before the borrower can respond at a preferred price.
What to check before borrowing
- Provider and any restrictions on loan use
- Advance rate, interest rate, term, and renewal rules
- Maintenance formula, call threshold, deadline, and cure level
- Whether collateral can be sold / substituted and liability for any shortfall after disposal
