$741 billion. That is the volume of assets managed by Global Business Companies (GBCs) registered in Mauritius — roughly fifty times the size of the island's domestic GDP. And yet, according to an analysis published by Le Mauricien and authored by economist Samad Ramoly, this colossal sector contributes only 8.4% to gross domestic product. A paradox that raises fundamental questions about the true nature of the Mauritian economic model.
Two Economies Under One Flag
Mauritius effectively operates as a two-speed system. On one side, the domestic ICT sector generates 5.7% of GDP and employs 15,390 people. On the other, the GBC sector manages massive financial flows, operating with approximately two directors per entity and benefiting from an effective tax rate estimated at around 3%, after having been excluded from 2025 global minimum tax reforms. Financial services broadly account for 13–14% of GDP.
This duality has documented perverse effects. The Bank of Mauritius long delayed interest rate increases — which became the global norm — to avoid choking an already fragile domestic economy, while the rupee lost 64% of its value against the dollar since 1994.
Brain Drain as an Indicator
Another alarm signal: Mauritius ranks 5th globally and 1st in Africa in the Human Flight and Brain Drain Index 2024. A country whose offshore economy is an international success but whose talent flees — a sign of a model that does not capture enough value-added for the local social fabric.
On the fiscal side, pressure remains: budget deficit at 9.8% of GDP and public debt at 88.6%, in a context where the Finance Bill adopted in July 2026 has already initiated structural pension reforms.
Why It Matters
The question raised by this analysis is not the legitimacy of Mauritius' offshore sector, but its articulation with the real economy. A country hosting $741 billion in assets while generating only an 8.4% GDP contribution must examine the quality of its value-capture mechanisms. As international corporate tax regulation tightens and the OECD pushes for a global minimum rate, the strategic repositioning window for Mauritius could narrow faster than anticipated.
