Is SACU Ready for a Monetary Union?

This research paper evaluates the viability of the South African Customs Union (SACU) transitioning from a Common Monetary Area (CMA) to a full monetary union. Using Southern African Development Community (SADC) convergence criteria, the authors find that while there is strong convergence in inflation, debt, and reserves, significant fiscal deficits in Lesotho and Swaziland present a major hurdle. The paper suggests that a monetary union would be beneficial and that the South African Reserve Bank (SARB) is well-positioned to lead the process.

• The study concludes that establishing a monetary union would be beneficial for SACU, with the South African Reserve Bank (SARB) potentially continuing to formulate monetary policy for the union.
• SACU member states demonstrate strong macroeconomic convergence in three key areas: inflation rates, national debt levels, and foreign reserve holdings. Inflation showed a trend toward the 2012 target of less than 5%, and debt-to-GDP ratios remained below the 60% target, including in Lesotho.
• Fiscal policy coordination is identified as a primary weakness and a significant challenge to a monetary union. Specifically, Lesotho and Swaziland have exhibited a lack of fiscal discipline, with fiscal deficits reaching 20% and 14% of GDP in 2010, and projected at 21% and 13% in 2011.
• The current Common Monetary Area (CMA) structure, where the South African rand serves as the anchor currency, has contributed to regional monetary stability. This is evidenced by lower average inflation rates in the CMA zone (9.2% from 1990–2002) compared to non-CMA SADC countries (801% overall, or 27.8% excluding hyperinflationary states).
• A significant risk for a Southern African monetary union is the structural diversity of member economies. The dominance of South Africa's economy and the SARB's sophistication may lead to a monetary policy that does not address the idiosyncratic shocks or development challenges faced by smaller, different economies in the region.
