Summary of "Exchange Rate Liberalization in Selected Sub-Saharan African Countries"

Core Content

This paper examines the impact of exchange rate liberalization and associated macroeconomic reforms in several sub-Saharan African (SSA) countries during the 1980s and early 1990s. It highlights the successes and failures of these reforms and draws out key lessons for future policy design.

Main Countries and Their Reforms

Ghana

• Before Reform: Severe economic decline, fiscal revenue down to 4-6% of GDP, imports compressed to 3% of GDP, and high inflation (up to 123% in 1981) with massive parallel market spreads (peaking at 4300% in 1982).
• Reform: Launched the 1983 Economic Reform Program (ERP), which included a sharp devaluation of the cedi (89% in 1983), tariff reforms, and the establishment of a foreign exchange auction system.
• Outcomes: Sustained recovery with real per capita income doubling, moderate inflation, and a transition to a market-determined exchange rate.
• Key Reforms:
  • Up-front devaluation to correct overvaluation.
  • Uniform tariff structure with a 30% duty rate.
  • Periodic exchange rate adjustments based on inflation differentials.
  • Introduction of foreign exchange bureaus and auction markets.

Kenya

• Before Reform: Gradual liberalization led to initial improvements in exports and current account balances, but growth recovery was not sustained.
• Reform: Implemented gradual liberalization of the foreign exchange market, including the removal of price controls and import licenses.
• Outcomes: Some growth recovery, but not sustained. Inflation increased due to excess money supply and government spending. Post-1992 policy tightening helped stabilize the exchange rate and restore credibility.
• Key Reforms:
  • Gradual liberalization of the foreign exchange market.
  • Policy tightening after the 1992 elections.

Malawi

• Before Reform: High parallel market spreads, low growth, and frequent foreign exchange shortages.
• Reform: Reverted to a controlled exchange rate regime, combined with fiscal and monetary reforms.
• Outcomes: Improved reserves and some success in stabilizing inflation, but not sustained growth. The country experienced significant volatility in the real effective exchange rate (REER) due to stop-reverse-and-go policies.
• Key Reforms:
  • Controlled exchange rate regime.
  • Fiscal and monetary policy coordination.

Mozambique

• Before Reform: Severe economic distress, 34% decline in real per capita income, high inflation, and low reserve coverage.
• Reform: After 1986/87, implemented floating exchange rate, reduced fiscal deficits, and improved monetary policy.
• Outcomes: Sustained high growth and moderate inflation. Real per capita income increased by 243% from 1986 to 2010.
• Key Reforms:
  • Floating exchange rate regime.
  • Fiscal consolidation and monetary tightening.

Tanzania

• Before Reform: High inflation, declining exports and imports, and severe parallel market spreads.
• Reform: Implemented comprehensive reforms including exchange rate liberalization and fiscal discipline.
• Outcomes: Strong growth recovery, real GDP per capita almost doubling, and inflation averaging 6.8% in 2000–10.
• Key Reforms:
  • Transition to a market-determined exchange rate.
  • Fiscal consolidation and monetary policy discipline.

Uganda

• Before Reform: Severe economic distress, overvalued exchange rate, and negative growth.
• Reform: Attempted floating exchange rate in 1980/81, followed by fiscal and monetary reforms.
• Outcomes: Sustained GDP growth of 7.5% from 1986 to 2010, real per capita income more than doubled, and inflation reduced below 10% after 1993.
• Key Reforms:
  • Floating exchange rate and partial price liberalization.
  • Fiscal and monetary discipline.

Zambia

• Before Reform: Long-term economic decline, high fiscal deficits, overvalued exchange rate, and low foreign exchange reserves.
• Reform: Attempted to correct imbalances but failed, leading to increased inflation and capital flight. After 1989, implemented structural reforms and fiscal discipline.
• Outcomes: Non-mining GDP growth became positive after 1995, and inflation declined significantly.
• Key Reforms:
  • Abandonment of previous flawed exchange rate policies.
  • Introduction of fiscal policy rules and monetary tightening.

Key Lessons

• Exchange Rate Liberalization: A critical component of successful reform, but must be part of a broader set of structural, fiscal, and monetary adjustments.
• Sustained Reforms: Short-term measures without long-term commitment often fail. Sustained and mutually reinforcing reforms are necessary for long-term economic recovery.
• Fiscal and Monetary Discipline: Essential to contain inflation and stabilize the real exchange rate. Loose fiscal policies and accommodative monetary policies can lead to initial inflation spikes.
• Pass-Through to Inflation: The impact of exchange rate devaluations on inflation depends on the policy environment and economic conditions. Tight fiscal and monetary policies can reduce inflationary pressures.
• Exchange Rate Volatility: High volatility in the real effective exchange rate (REER) can be more damaging than the volatility associated with floating exchange rates.
• Expectations Matter: Credible and sustained reforms are necessary to build market confidence and reduce the risk of policy reversals.
• External Assistance: Played a supportive role in the success of reforms, particularly in countries with weak fiscal and monetary frameworks.
• Structural Reforms: Needed to improve efficiency, encourage private investment, and reduce dependency on a single export commodity.

Conclusion

The paper concludes that successful exchange rate liberalization requires a combination of structural reforms, fiscal discipline, and monetary policy tightening. It emphasizes the importance of avoiding stop-and-go policies and ensuring that reforms are credible and sustained. The cases of Ghana, Tanzania, and Uganda illustrate the positive outcomes of well-executed reforms, while Malawi and Zambia highlight the risks of incomplete or poorly sustained liberalization efforts.
