How Does the Concept of “Margin” Apply to the Seller (Writer) of an Option?

An option writer, particularly of an uncovered option, must post margin to cover the potential loss, which can be substantial or unlimited. This margin acts as a performance bond to the clearing house or counterparty.

The margin is calculated based on the risk of the position and is subject to maintenance requirements. Margin protects the counterparty from default.
