## ARTICLE:

The Stock Exchange of Mauritius (SEM) is implementing two major operational reforms designed to enhance market competitiveness and align with international best practices. The exchange will extend daily trading hours while simultaneously transitioning from T+3 (trade date plus three days) to T+2 (trade date plus two days) settlement cycles—a move that mirrors standards adopted by major global exchanges and signals Mauritius's intent to strengthen its position as a financial hub for African capital markets.

### Why Is T+2 Settlement Critical for Mauritius?

The shift to T+2 settlement represents a fundamental modernization of market infrastructure. Currently, investors and brokers operating on the SEM experience a three-day lag between trade execution and final fund transfer—a timeline that increases counterparty risk, ties up capital longer than necessary, and creates friction for cross-border transactions. T+2 settlement compresses this window by one full business day, reducing systemic risk while accelerating cash flow for institutional investors managing regional portfolios across East and Southern Africa.

For international investors entering Mauritian equities—particularly those trading mining, textiles, or financial services stocks—faster settlement means reduced exposure to currency volatility and operational delays. Brokers will also face lower margin requirements and reduced inventory costs, potentially translating into tighter bid-ask spreads and lower transaction fees for retail participants.

### How Extended Trading Hours Boost Market Depth

The SEM's decision to extend trading hours addresses a structural liquidity challenge. Mauritius operates in UTC+4, placing it between Asian close and European open—a timing disadvantage that historically limited participation from both regions. Longer trading sessions create overlapping windows with European markets (especially London close) and early Asian trading, enabling better price discovery and deeper order books during critical volatility windows.

Extended hours particularly benefit algorithmic traders and regional asset managers who currently face compressed liquidity in the final hours of the traditional session. This operational change also reduces the "overnight gap risk" that often plagues smaller exchanges, where major news between close and open can create violent opening gaps.

### Market Implications for the SEM and Region

These reforms arrive at a critical moment. The Mauritian economy faces headwinds from sugar sector decline and tourism volatility, yet its equity market—home to multinational financial services firms, textile exporters, and manufacturing conglomerates—remains undershopped by international investors. T+2 and extended hours remove technical barriers to entry for asset managers in London, Johannesburg, and Dubai who view Mauritius as a gateway to sub-Saharan African equities.

Regionally, the SEM now moves closer to alignment with the Johannesburg Stock Exchange (JSE), which adopted T+2 in 2017. This convergence could enable cross-listing initiatives and encourage Mauritian corporates to attract South African institutional capital—a significant pool of regional investment seeking diversification outside the JSE's concentrated large-cap base.

The reforms also position Mauritius competitively against the nascent East African Securities Exchange Alliance, signaling that the island nation remains committed to deepening African financial integration rather than retreating into niche status.
