Mauritius FSC Introduces New Authorised Bank Signatory Regime for GBCs — Effective 19 June 2026

What Has Changed: The Mauritius Financial Services Commission has amended its Guidelines for Management Companies, inserting a new paragraph 9.2. Every Global Business Company (GBC) bank account must now include at least one officer of the licensed Management Company as an authorised signatory. That officer must be an approved person under Section 24 of the Financial Services Act — individually vetted and approved by the FSC. Previously, GBC bank accounts could be operated with signatories drawn exclusively from the beneficial owner, nominee directors, or other parties outside the Management Company structure.

The amendment closes a gap that had allowed banking control of a Mauritius GBC to sit entirely outside the regulated administrator. By requiring an approved Management Company officer on every mandate, the FSC ensures that a vetted, accountable individual with a genuine connection to the jurisdiction is party to the company's banking arrangements. The change is procedural in form but substantive in effect, reshaping how thousands of GBC bank accounts must be structured.

Why This Matters for GBC Operators: The FSC's stated rationale is to strengthen substance, accountability, and anti-money-laundering oversight. The practical implications are immediate. Existing GBCs must update their bank mandates before 19 September 2026 — three months from the 19 June effective date. Management Companies must ensure at least one approved officer is on the mandate of every GBC they administer. Beneficial owners retain operational access but no longer have sole signatory control. And new GBC incorporations from 19 June must structure banking with a Management Company officer from day one.

For beneficial owners accustomed to unilateral control of company banking, the shift requires a recalibration of expectations. The new regime does not strip owners of access or operational involvement, but it does insert a regulated co-signatory into the chain of control. For Management Companies, the change increases administrative responsibility and exposure, since the approved officer is now formally accountable for the banking relationships of every entity on their book.

Compliance Steps: Step 1 — audit all bank accounts to identify which GBC mandates currently lack an approved Management Company officer. Step 2 — contact your Management Company to arrange for an approved officer to be added to each affected mandate. Step 3 — allow two to six weeks for bank mandate amendments, since institutions will require updated board resolutions and KYC documentation. Step 4 — review any new GBC structures in the pipeline to ensure banking is configured correctly from incorporation.

Why Mauritius GBC Remains a Leading Structure: Despite the tightened rules, the Mauritius GBC remains highly effective. It carries a 15% corporate tax rate with foreign tax credits that can reduce the effective rate substantially, access to 46 double tax treaties, and an EU- and OECD-compliant framework. The FSC's ongoing tightening is consistent with Mauritius positioning itself as a substance-first jurisdiction rather than a light-touch offshore centre, and that credibility is precisely what makes the GBC durable as a vehicle for international holding and investment structures.

Operators who treat the 19 September mandate deadline as a routine administrative update, rather than a scramble, will absorb the change with minimal disruption. Those who delay risk operational friction with their banks and potential supervisory attention from the FSC. The message from the regulator is consistent with its trajectory over the past several years: Mauritius intends to remain a respected jurisdiction, and that reputation is built on enforceable substance rather than convenience.
