Final answer:
Customers who are not broker-dealers must maintain a minimum amount of net liquid assets to carry unlisted derivatives in a portfolio margin account.
Step-by-step explanation:
Customers who are not broker-dealers and wish to carry unlisted derivatives in a portfolio margin account must maintain a certain minimum amount of net liquid assets. The amount varies depending on the type and size of the derivatives positions held.
For example, the Financial Industry Regulatory Authority (FINRA) sets the minimum net capital requirement for non-broker-dealer customers carrying unlisted derivatives in a portfolio margin account at $150,000. This requirement ensures that customers have sufficient funds to cover potential losses and meet margin calls.
