Mauritius FSC Tightens Bank Signatory Rules for Global Business Companies: What Changes in 2026

The Mauritius Financial Services Commission has introduced new requirements governing authorised bank signatories at Global Business Companies (GBCs), tightening the substance regime that underpins the island's status as a structuring hub. The changes are aimed at ensuring that the individuals who control a GBC's bank accounts have a genuine connection to Mauritius rather than acting purely on instruction from abroad.

At its core, the new signatory regime requires that GBCs maintain authorised bank signatories who meet residency and competence criteria, and who can demonstrate real decision-making authority over the company's banking relationships. The FSC's concern is that bank mandates have in some cases been held by individuals with no meaningful presence in the jurisdiction, hollowing out the substance that GBC status is supposed to evidence.

The impact lands most heavily on GBCs used as holding structures for African and Asian investment. Mauritius has long served as a conduit for capital flowing into the African continent and across Asia, with investors valuing its network of double-taxation treaties and investment-protection agreements. Many of those holding vehicles were administered lightly, and the new rules require sponsors to revisit who holds banking authority and whether that arrangement now satisfies the FSC.

For fund managers using Mauritius as a hub, the implications extend to operational governance. Funds structured through Mauritian vehicles will need to confirm that signatory arrangements align with the tightened expectations, particularly where banking decisions were effectively delegated offshore. Managers should anticipate closer scrutiny of board composition, the location of decision-making, and the documentation that evidences local control.

Despite the additional burden, Mauritius remains one of the top jurisdictions for Africa-Asia investment structuring. Its treaty network, political stability, common-law heritage and established service-provider ecosystem continue to offer advantages that newer entrants cannot easily replicate. The FSC's tightening is better understood as a defence of the jurisdiction's reputation than a retreat from it, responding to international pressure on substance to keep Mauritius off grey lists.

The reforms also reflect a wider global direction of travel. Substance requirements have hardened across offshore and midshore centres as the OECD's standards on economic substance and information exchange have matured. Jurisdictions that fail to evidence genuine activity risk reputational damage and the loss of treaty benefits, so Mauritius is moving to stay ahead of the curve rather than react to censure.

Practical steps for compliance start with a review of every GBC's existing bank mandate against the new criteria. Sponsors should identify which signatories qualify, appoint suitably resident and authorised individuals where gaps exist, and ensure board minutes and banking resolutions reflect that control genuinely sits in Mauritius. Engaging the management company early, ahead of the FSC's review cycles, will be far less costly than remediating under supervisory pressure.
