What’s changing, and why is it important?
In July 2026, the Ministry of Economy & Tourism of the United Arab Emirates (the “Ministry” and “UAE”) published its Guidelines on Relevant Market Definition (the “Guidelines”), providing a detailed look into the Ministry’s framework for market definition assessment. The Ministry considers market definition to be a “fundamental pillar” to the competitive assessment across all competition enforcement contexts and a “crucial stage” in competition enforcement.
The issuance of the Guidelines marks a further important step in the implementation of the UAE’s competition law regime. It follows the introduction of revised merger control thresholds in 2025 and the adoption in April 2026 of implementing regulations for the 2023 Federal Competition Law (see our previous blog on these reforms).
The Guidelines are particularly important for the UAE’s merger control regime, where filing obligations are dependent on parties meeting revenue and/or market share thresholds in the “relevant market” in the UAE. The introduction of the Guidelines provides a crucial tool to merging parties and advisers for determining when transactions may require mandatory notification to the Ministry. More substantively, the Guidelines will provide an important source to help merging parties prepare the “economic report” on the competitive effects of a merger required by the UAE merger notification rules. Beyond merger control, the Guidelines will also provide an important tool for self-assessment of behavioural competition law compliance.
