Réunion's retail sector is undergoing a historic shift. On July 31, 2026, France's Competition Authority officially approved the merger between Groupe Caillé, which operates around fifty Leader Price stores across the island, and IBL, the Mauritian conglomerate that controls Make Distribution, the operator of four Run Market hypermarkets.
A New Third Force Takes on the Carrefour-Leclerc Tandem
The combined entity will bring together more than 50 retail outlets, immediately positioning itself as the third-largest player in Réunion's grocery market — behind the dominant Carrefour-Leclerc duo. For consumers already dealing with one of France's highest costs of living, the emergence of such a large new player raises legitimate questions about mid-term competitive dynamics.
The Coca-Cola Clause at the Heart of Negotiations
The deal was approved — but with binding commitments. The authority flagged a specific risk tied to IBL's subsidiary Edena, which is set to secure exclusive Coca-Cola bottling rights on Réunion from October 1, 2026. That dominant position over the island's bestselling beverages created potential for anti-competitive practices.
IBL pledged to supply all Réunion-based distributors with Coca-Cola products on «equitable, transparent and non-discriminatory» terms, with no exclusive bundling allowed with other products in its portfolio. Regulators will monitor compliance over time.
IBL Deepens Its Footprint on Réunion
For IBL, this deal marks a major strategic move across the Indian Ocean region. The Mauritian conglomerate, already active in numerous sectors throughout the islands, extends its commercial reach on Réunion well beyond its existing four hypermarkets. Groupe Caillé, a long-established local distributor, brings its proximity network and deep knowledge of Réunion's commercial fabric.
Why It Matters
This Franco-Mauritian merger illustrates the deepening economic integration between the two most populous islands of the Indian Ocean. It comes amid heightened scrutiny over purchasing power in France's overseas territories, as national and local governments seek to tackle the high cost of living. A third heavyweight in retail should, in theory, sharpen price competition — provided the commitments made to regulators are genuinely upheld. The coming months will be the real test.
