FINRA has updated its options rules to address binary contracts, including payouts tied to an issuer’s reported financial or operating metrics. Regulatory Notice 26-21, published on 26 October, confirms that the amendments took effect on 22 October. They also accommodate options guaranteed by registered clearing agencies other than the Options Clearing Corporation.[1]
The changes cover public communications, trading controls and margin. FINRA says the purpose is to apply its existing listed-options framework consistently as product structures and clearing arrangements expand. For member brokers, this brings the new contracts into established approval, disclosure and supervision processes.[1]
The payoff determines the funding requirement
Rule 2360 defines a binary as a cash-settled option with a settlement amount fixed when the contract is created. A call pays that amount if the expiry value meets or exceeds its threshold; a put pays if the value is below it. The underlying can be a security, index or metric, with trading mechanics governed by the listing exchange.[2]
That structure makes the settlement definition central to a broker’s product description. A client assessing a contract on a company metric needs to understand which reported measure determines the result and the relevant threshold. A forecast about the company’s share price alone would not answer those questions.
FINRA’s binary-option margin interpretations
| Position | Specified treatment |
|---|---|
| Long binary option | The option must be paid for in full.Source 3 |
| Short binary option | The ordinary margin requirement is the contract’s exercise settlement amount.Source 3 |
| Qualifying offsetting binary spread | No margin on the short when the fully paid long satisfies the same-underlying, expiry, settlement-amount and strike conditions.Source 3 |
| Qualifying short call and short put | One settlement amount is required when the contracts meet the interpretation’s matching conditions.Source 3 |
The offsets are conditional. For the spread treatment, the long must have at least the short’s settlement amount and expire at the same time; its strike must be higher for puts or lower for calls. The paired-short treatment requires the same underlying, expiry and settlement amount, with the put strike no higher than the call strike.[3]
The operational consequence is that a platform cannot identify an offset simply because two contracts mention the same issuer. Its position and margin records need to distinguish the metric, expiry and payout terms. Otherwise, a visually similar pair may be treated as a hedge even though it fails the prescribed conditions.
Distribution and position controls still matter
The amended Rule 2360 ties exchange-traded binary position limits to those of the listing exchange. Its options-account provisions also require a written customer agreement after account approval and acknowledgment of the relevant disclosure documents and clearing-agency rules. These obligations make clearing identity part of the customer documentation as well as an operational arrangement behind the trade.[2]
In its filing notice, the SEC waived the normal 30-day operative delay, allowing the rule change to operate upon filing. The document retains the Commission’s power to suspend it temporarily within 60 days. Its formal description as a proposed rule change therefore does not mean brokers are waiting for these amendments to become operative.[4]
This is a change to the rules governing FINRA members’ handling of listed options. Availability of an individual contract still depends on the exchange’s product terms and the broker’s offering; the notice does not announce a universal customer launch.[1]
