In Regulatory Notice 19-21, FINRA announced that exchange-traded notes ("ETNs") will now be treated differently than investment grade debt securities under the maintenance margin requirements of FINRA Rule 4210(c).3 That rule requires strategy-based accounts to maintain equity equal to 25% of the current market value of all margin securities long in the account, and the greater of 5% of the principal amount or 30% of the current market value of the debt securities short in the account. Debt securities, which include ETNs, are margin securities.

FINRA Rule 4210(e)(2)(C) provides some exceptions, allowing reduced margin requirements for investment grade debt securities, listed non-equity securities and other margin non-equity securities. ETNs are within those exceptions, because they are listed on a national securities exchange and their issuers typically are rated investment grade.
