Are all products with a Yes/No outcome binary options?

No. Relevant factors include the contractual claim, underlying, payout, market structure, target market and applicable law.

Are binary options completely prohibited in Germany?

BaFin’s product-intervention measure generally covers the marketing, distribution and sale of the binary options within its scope to retail clients. It does not amount to a blanket prohibition of every binary payout structure or every Yes/No event question.

What made retail binary options toxic?

The problematic combination comprised, in particular, an all-or-nothing payout, very short maturities, negative expected value, opaque OTC price formation, no secondary market and provider conflicts of interest.

BINARY OPTIONS / PRODUCT ANATOMY

The binary outcome
was not the toxic element.

A legitimate mathematical payout structure became problematic when combined with short maturities, negative expected value, opaque OTC distribution and a provider that also acted as counterparty.

01 / FROM OPTION TO DIGITAL PAY-OFF

One line of development,
three different questions.

Black–Scholes–Merton explains the valuation of standard European options under model assumptions. It is neither a seal of quality nor proof of fairness for a subsequent distribution product.

Conventional option

The right to buy or sell an underlying at the strike. Value at expiry changes with distance from the strike; it is not merely zero or fixed.

VARIABLE PAYOUT

Black–Scholes–Merton

A valuation framework using inputs such as spot price S, strike K, time to expiry T, interest rate r and volatility σ. The model assumptions remain part of the result.

VALUATION MODEL · 1973

Digital / Binary

Cash-or-nothing and asset-or-nothing are established derivative payouts. The mathematical payout profile alone does not determine whether a specific offering is toxic.

FIXED OR ZERO

02 / TOXICITY STACK

Toxicity arose from the stack.

The more of these characteristics coincide, the further the product shifts from transparent risk transfer towards conflict-laden short-term speculation.

01All-or-nothing payout

02Extremely short maturities and repetition

03Provider as direct counterparty

04Proprietary price and lifecycle control

05No liquid secondary market or fair exit

06Aggressive bonuses and misleading simplicity

07Operational fraud and payout risks

BREAK-EVEN CHECK55,56^%

If a winning position pays €80 while a loss costs €100, a 50% success rate is insufficient. Before costs, 55.56% is required to reach an expected value of zero.

p × 80 − (1−p) × 100 = 0

03 / SCOPE OF INTERVENTION

What ended up on the index.
And what did not automatically.

The precise scope follows from the relevant measure and its exemptions. The shorthand ‘binary is prohibited’ is analytically too crude.

CORE SCOPE

Retail distribution of covered binary options

Marketing, distribution and sale of qualifying binary options to retail clients—where the product is a financial instrument and no defined exemption applies.

NOT CATEGORICALLY COVERED

Conventional exchange-traded options
Binary payouts as a mathematical structure
Every conceivable Yes/No event question
Every prediction market irrespective of design
Non-monetary opinion and simulation markets
Professional activity as categorically ‘permitted’—other duties remain

Important: ‘Not covered by this product-intervention measure’ does not automatically mean ‘exempt from authorisation’ or ‘permissible’. Financial-market, gambling, consumer, data and advertising law require separate assessment.

04 / DEBATE-STANDARD POSITION

Counterarguments that must withstand scrutiny.

Classification before intervention

First determine whether the specific event question and contractual mechanics constitute a financial instrument at all.

Substance before label

A binary outcome does not automatically turn an information market into a retail binary option.

Exchange ≠ House

Two-sided matching with transparent price formation differs from a provider that sets the quote and acts as counterparty.

Exit changes risk

Secondary trading and a visible order book differ materially from an irreversible fixed payout held to expiry.

Governance is a product feature

Objective resolution, a source hierarchy, surveillance, position limits and an audit trail reduce classic adverse incentives.

Retail protection remains central

Classification does not negate the need for protection. It may require a virtual-first design, professional target markets or regulated infrastructure.

ESMA · 2026

Event Contracts are not classified by name alone. The event question helps determine whether a financial instrument exists; for a binary financial instrument, existing national measures are relevant.

GGL · GERMANY

The public position is clearly negative on paid betting on public affairs. It does not automatically determine the treatment of every non-monetary information simulation or its MiFID classification.

05 / REGULATORY EXPERIENCE

Practice sharpens the questions.
Sources support the statement.

The assessment logic combines longstanding experience in financial-market, platform and product development with published legal and regulatory sources. Proprietary regulatory experience improves the quality of the questions; it is not presented as a public claim to authority.

06 / PRIMARY SOURCES
