Sudan: Summary of Selected Issues

Core Content

This document provides an analysis of Sudan's monetary policy framework and its effectiveness in transmitting monetary policy to inflation, as well as an assessment of gold taxation and external stability. The report is prepared by the International Monetary Fund (IMF) as part of its periodic consultation with Sudan and is based on data available up to September 5, 2013.

Main Policy Issues

1. Monetary Transmission Mechanism in Sudan

• Introduction: The secession of South Sudan in 2011 caused significant economic and fiscal shocks, leading to rapid deterioration in Sudan's economic conditions. This has impacted the effectiveness of monetary policy and increased inflationary pressures.
• Monetary Policy Framework: Sudan's monetary policy is based on a fixed exchange rate system, but the presence of multiple exchange rates weakens its effectiveness. The central rate, commercial banks rate, and parallel market rate are key components of the exchange rate regime.
• Channels of Transmission:
  • The interest rate channel is not effective due to the Islamic banking system's prohibition of interest and the underdevelopment of the interbank market.
  • The asset price channel is also underdeveloped, as asset markets are not well developed.
  • The exchange rate channel and bank lending channel are the primary mechanisms through which monetary policy affects inflation.
• Model and Estimation:
  • A regression model is used to estimate the impact of reserve money, nominal effective exchange rate (based on the parallel rate), and private sector credit on inflation.
  • The results show that reserve money has a positive and significant effect on inflation with a lag of 4 to 5 months.
  • The exchange rate (NEER) has a negative effect with a lag of 3 months, indicating that devaluation increases inflation.
  • Private sector credit has a significant and immediate effect on inflation.
• Policy Recommendations:
  • A prudent fiscal policy is necessary to support monetary policy.
  • Reforms of the monetary and financial system are needed to enhance the central bank's operational independence and improve transparency.
  • Unification of exchange rates should be prioritized to reduce inflationary pressures and improve the effectiveness of monetary transmission.
  • Using reserve money as a nominal anchor is recommended to enhance the effectiveness of monetary policy.
  • Termination of central bank participation in financial institutions is needed to prevent inflationary pressure through liquidity injections.

2. Gold Taxation in Sudan

• Background: Sudan's tax-to-GDP ratio is low, limiting its fiscal space for development. The gold sector is a major export earner, with its share in total exports increasing from 1% in 2008 to over 40% in 2012.
• Current Tax Regime: The gold sector contributes less than 0.1% of total tax revenue, indicating inefficiencies in the current taxation system.
• Taxation Principles:
  • Natural resource taxation should be designed to capture economic rents above normal profits.
  • A special regime is needed to ensure that the government captures a fair share of the mineral wealth for socio-economic development.
• Recommendations:
  • Streamline taxation on the gold sector to increase revenue.
  • Introduce progressivity for large mining companies.
  • Extend the fiscal net to include small producers.
  • Compare Sudan's gold taxation regime with those of other countries to identify best practices.

External Stability Assessment

• Background: Sudan's external stability is assessed in terms of competitiveness, reserve adequacy, and exchange rate dynamics.
• External Competitiveness: The country's export composition and trade terms are analyzed to evaluate its competitiveness in international markets.
• Price Competitiveness: The impact of exchange rate movements on domestic prices and inflation is examined.
• Reserve Adequacy:
  • Sudan's reserve levels are assessed against common rules of thumb and optimal levels.
  • The study highlights the importance of maintaining adequate reserves to support external stability.
• Exchange Rate Dynamics: The relationship between exchange rates and macroeconomic indicators, such as GDP and inflation, is explored.
• Conclusion: The findings emphasize the need for a comprehensive approach to stabilize the economy, including fiscal and monetary reforms, and improving the effectiveness of the monetary transmission mechanism.

Key Information

• Sudan's monetary policy framework is constrained by the Islamic banking system and the lack of effective instruments.
• Inflation is driven by reserve money, exchange rate movements, and private sector credit.
• The transmission lags have been significantly reduced since the secession of South Sudan.
• The gold sector is a crucial part of Sudan's economy and offers a promising avenue for increasing tax revenue.
• Fiscal reforms are essential to support monetary policy and reduce inflation.
• Exchange rate unification is recommended to stabilize the economy and reduce inflationary pressures.
• Central bank independence and transparency are critical for effective monetary policy implementation.
