Customer Margin Balance Report Due – Period ending 12/31/2018

FINRA Rule 4521 requires member firms that carry customer margin accounts to submit debit and credit balances and all securities margin accounts.

Customer Margin Balance Reporting and Margin Statistics

FINRA Rule 4521 requires that member firms that carry customer margin accounts must submit — via the Customer Margin Balance Form — the following numbers:

• the total of all debit balances in securities margin accounts
• all free credit balances in all cash accounts
• all securities margin accounts on a settlement date basis as of the last business day of the month

After collecting this data via the Customer Margin Balance Forms, FINRA displays it in aggregate form on our Margin Statistics page.
