ESMA publishes first FASTER market capitalisation ratios for EU Member States

Executive Summary

ESMA has published, for the first time, annual market capitalisation figures and market capitalisation ratios for EU Member States for reference years 2024 and 2025. The publication implements ESMA’s mandate under the FASTER Directive, which requires ESMA to develop the calculation methodology and publish annual figures and ratios. The data is relevant because Member States whose market size exceeds 1.5% of total EU market capitalisation for four consecutive years are subject to specific withholding tax relief requirements. This update does not itself introduce a new firm-level filing template or an immediate operational deadline, but it provides an official reference dataset that tax authorities, financial intermediaries, custodians, withholding agents and market participants should use in FASTER implementation planning. Under the Directive, Member States must transpose FASTER rules by 31 December 2028 and apply them from 1 January 2030. Firms should treat ESMA’s annual publication as a recurring reference-data control for withholding tax relief scoping.

What Changed

newFirst ESMA FASTER market capitalisation publication

No first ESMA-published annual market capitalisation dataset under the FASTER mandate had been available.

New

ESMA has published the initial annual figures and ratios and states it will continue publishing updated figures each year.

newOfficial reference data for the 1.5% FASTER threshold

Market participants lacked the first official ESMA reference publication for this FASTER threshold assessment.

New

The 2024 and 2025 reference-year ratios provide the first official inputs for tracking the threshold condition.

modifiedFASTER implementation scoping evidence

Implementation planning could identify the FASTER framework but not use ESMA’s first annual Member State ratio publication.

New

Tax operations and compliance teams can update jurisdiction scoping matrices using the ESMA-published 2024 and 2025 data.

newRecurring annual monitoring expectation

No recurring ESMA annual publication cycle under the FASTER mandate had yet been implemented.

New

Firms should expect annual updates and maintain a repeatable control to refresh FASTER reference data.

Field	Validation rule
EU Member State	Maintain the Member State identifier used in ESMA’s annual FASTER market capitalisation publication for each reference year.
Reference year	Record separate ESMA-published values for the 2024 and 2025 reference years and refresh when ESMA publishes annual updates.
Market capitalisation	Use ESMA’s published annual market capitalisation figure as the official source for FASTER scoping controls.
Market capitalisation ratio	Use ESMA’s published ratio to monitor whether a Member State exceeds 1.5% of total EU market capitalisation.
Four-consecutive-year threshold status	Track the 1.5% condition over consecutive ESMA annual publications; do not infer final national obligations without the Directive requirements and national implementing law.
