FINRA clarifies options rules now cover binary options, effective immediately
FINRA's October 28 digest confirms a rule change that already took effect this week: binary options now fall squarely under existing options oversight. Compliance and legal teams at member firms offering or clearing these products should understand which rules now apply and the margin computation changes before examiners ask about them.
- Regulatory Notice 26-21, published Oct. 26, 2026, applies Rules 2220, 2360 and 4210 to binary options.
- The notice covers binary options whose payout is based on an issuer's reported financial or operating metrics.
- It also covers binary options cleared by a registered clearing agency other than The Options Clearing Corporation.
- FINRA updated its Rule 4210 interpretations to clarify the required margin computations for binary options.
- The rule changes took effect Oct. 22, 2026, four days before the explanatory notice was published.
