EU MiFID II framework (Markets in Financial Instruments Directive 2) imposes specific best execution and cost disclosure requirements on EU-licensed CFD brokers including the CySEC-licensed entities of major retail forex brokers. The requirements mandate specific quarterly best execution reports (RTS 27, RTS 28), specific cost disclosure documents (KIID-equivalent for CFDs), and specific ongoing transparency obligations. For zero-commission brokers operating EU entities, the disclosure requirements provide specific data that calm-market marketing positioning doesn't capture.
For traders comparing zero-commission accounts in 2026, MiFID II-disclosed data provides specific insight into actual execution and cost characteristics that goes beyond marketing. The disclosure framework matters more for EU residents directly subject to the entities; for non-EU residents, the data is informative but the entities of relevance are different.
What MiFID II Specifically Requires
The framework imposes several specific reporting obligations.
Best execution policy disclosure: Brokers must publish best execution policy explaining how they execute client orders, the criteria they apply, and the venues used.
RTS 27 reports: Quarterly publication by execution venues (which can include forex brokers) showing execution quality data including price improvement, speed, likelihood of execution, and other metrics.
RTS 28 reports: Annual publication by investment firms showing the top 5 execution venues for each class of financial instrument, plus specific summary data on execution quality.
KIID-equivalent CFD disclosures: For CFDs specifically, MiFID II's product intervention measures require specific cost disclosure including total costs as percentage of investment.
Specific ongoing client communication: Trades must be confirmed with specific cost breakdown.
Specific risk warnings: Standardised risk warnings on broker marketing to retail clients.
Specific PRIIPs KID: Specific information document for retail clients in EU.
The combined framework creates substantial reporting obligation.
What Specific Data Brokers Disclose
For specific CySEC-licensed entities of major brokers, the data typically includes:
Specific spread averages: Quarterly average spread across major instruments. Specific data per instrument and account type.
Specific execution metrics: Average execution speed (microseconds typical), specific slippage patterns, specific rejection rates.
Specific top venues: Top liquidity providers/venues for each class of instrument.
Specific cost percentages: Total costs as percentage of typical investment over standard time period.
Specific complaint statistics: Aggregate complaint volumes and resolution patterns.
Specific specific event-day data: Specific event execution quality where required.
The data is published publicly typically quarterly or annually depending on specific requirement.
What the Data Reveals About Specific Brokers
For specific CySEC entities of major brokers in 2026:
Specific XM CySEC entity (Trading Point of Financial Instruments Ltd): RTS 27 reports show specific execution metrics. KIID-equivalent disclosure shows EUR/USD typical cost as percentage of investment.
Specific Exness CySEC entity: Similar specific reporting framework.
Specific Pepperstone EU entity: Specific reports.
Specific IC Markets EU entity: Specific reports.
The specific data is publicly available and provides verification of marketing claims.
How the EU Disclosure Differs From Offshore Disclosure
EU-licensed entities of brokers face the MiFID II framework. Offshore-licensed entities (FSA Seychelles, IFSC Belize, etc.) do not face equivalent disclosure requirements.
Specific implications for EU residents: EU residents using EU-licensed brokers benefit from specific transparency. The data supports informed broker selection.
Specific implications for non-EU residents: Non-EU residents typically use offshore-licensed broker entities that don't face MiFID II disclosure. Specific data is less available.
Specific cross-broker comparison limitation: Comparing specific brokers requires comparable data. EU vs offshore brokers face different disclosure standards.
Specific implication for specific brokers operating both: Brokers operating both EU and offshore entities show different specific characteristics across entities. EU entity data may not apply to offshore entity directly.
The asymmetry is significant for cross-jurisdiction analysis.
What the EU Disclosure Reveals About All-In Cost
The KIID-equivalent disclosure typically shows total cost as percentage of investment over standard time period (e.g., 1 year for a typical retail trader). The figure incorporates:
Specific spread cost: The implicit cost of the broker's spread.
Specific commission: Where applicable.
Specific overnight financing: Where applicable for positions held overnight.
Specific other fees: Where applicable.
Specific total: Combined annual cost as percentage.
The figure reveals true all-in cost rather than the broker's marketing-friendly individual line items.
How to Use the MiFID II Data
For traders selecting brokers, several practices apply.
Specific RTS 27 review: Review broker's published RTS 27 reports for execution metrics.
Specific RTS 28 review: Review annual RTS 28 disclosure for top venue and specific summary data.
Specific KIID review: Review KIID-equivalent disclosure for total cost as percentage.
Specific cross-broker comparison: Compare specific data across brokers.
Specific broker-specific website verification: Most brokers publish specific reports on their EU-entity websites.
Specific specific complaint analysis: Where available, specific complaint patterns provide additional context.
The data supports informed broker selection beyond marketing.
What MiFID II Doesn't Address
Several limitations of the MiFID II framework.
Specific applicability: MiFID II applies only to EU-licensed entities. Offshore broker activity beyond MiFID II reach.
Specific reporting frequency: Quarterly reporting may not capture short-term operational changes.
Specific aggregation: RTS reports show aggregate data. Specific individual situations may differ.
Specific instrument-specific variation: Reports may not capture variation across all specific instruments.
Specific event-day data: Specific event-day execution often not separately disclosed.
The framework provides substantial transparency but specific limits exist.
What Specific 2026 Updates Have Brought
Several specific 2026 developments.
Specific MiFID II review: EU has continued specific reviews and adjustments to MiFID II framework.
Specific DORA integration: Digital Operational Resilience Act effective 2025 has produced specific additional disclosure obligations for EU entities.
Specific climate-related disclosures: Specific ESG/climate disclosures expanding into broader financial framework.
Specific transparency platform initiatives: EU initiatives to standardise transparency framework continue.
The framework continues evolving.
The Decision Reading
For EU-resident traders selecting forex brokers, MiFID II disclosure data provides specific transparency supporting informed selection. Reviewing specific broker RTS reports and KIID disclosures supports specific decision-making.
For non-EU residents, the framework is less directly applicable but EU broker data provides specific reference for broader broker assessment.
For specific multi-jurisdiction analysis, the disclosure asymmetry between EU and offshore entities should be explicitly accounted for.
Honest Limits
The MiFID II framework details reflect publicly available regulatory text and broker-side disclosure through 2026. Specific reporting interpretations vary. None of this constitutes broker or regulatory advice.
