Mauritius faces an invisible bank tax with a 4.25% interest rate gap, hindering economic growth

This gap acts as an "invisible tax" on the country's vital forces, with a banking oligopoly accused of stifling local entrepreneurs and citizens. The article argues that lowering the key interest rate, a popular demand to stimulate growth, would be a macroeconomic error. Such a reduction would immediately diminish the purchasing power of savers and retirees by cutting savings account yields and accelerate the depreciation of the Mauritian rupee.

Since Mauritius imports most consumer goods, a weaker currency would fuel imported inflation, severely impacting household budgets for essentials like food, fuel, and medicine. For local businesses, a weakened rupee would exacerbate the chronic shortage of foreign currency, making it difficult for SMEs to finance raw material purchases in USD or Euros.
