Many central banks in low-income countries in Sub-Saharan Africa are modernising their monetary policy frameworks. Standard statistical procedures have had limited success in identifying the channels of monetary transmission in such countries. Here we take a narrative approach, following Romer and Romer (1989), and center on a significant tightening of monetary policy that took place in 2011 in four members of the East African Community: Kenya, Uganda, Tanzania and Rwanda. We find clear evidence of the transmission mechanism in most of the countries, and argue that deviations can be explained by differences in the policy regime in place.

Central banks in emerging and developing economies (EMDEs) have been modernizing their monetary policy frameworks, often moving toward inflation targeting (IT). However, questions regarding the strength of monetary policy transmission from interest rates to inflation and output have often stalled progress. We conduct a novel empirical analysis using Jordà’s (2005) approach for 40 EMDEs to shed a light on monetary transmission in these countries. We find that interest rate hikes reduce output growth and inflation, once we explicitly account for the behavior of the exchange rate. Having a modern monetary policy framework—adopting IT and independent and transparent central banks—matters more for monetary transmission than financial development.

Monetary policy transmission in EMs has been found to be weak historically due to under-developed financial markets and heavy central bank intervention in FX markets that undermine the exchange rate channel. Against this background, this paper investigates the transmission of monetary policy, including the role of external factors, in Malaysia and highlight findings that could be relevant for other EMs. We find an important role for the credit and the exchange rate channels. Further, we also find a complementary role for policy tools including Foreign Exchange Intervention (FXI) and liquidity tools such as Statutory Reserve Requirement in shaping the transmission of monetary policy. We then explore the spillover effects of external global factors including global monetary policy and global commodity prices on monetary policy transmission in a small open economy such as Malaysia. The results show that while global commodity prices do not impair monetary policy transmission, global monetary policy tightening could complement domestic efforts to achieve price stability by inducing a global disinflation. Finally, monetary policy transmission is delayed and weakened in high inflationary environment, with the implication that more aggressive and preemptive policy actions may be needed in such cases.

Over the past two decades, many low- and lower-middle income countries (LLMICs) have improved control over fiscal policy, liberalized and deepened financial markets, and stabilized inflation at moderate levels. Monetary policy frameworks that have helped achieve these ends are being challenged by continued financial development and increased exposure to global capital markets. Many policymakers aspire to move beyond the basics of stability to implement monetary policy frameworks that better anchor inflation and promote macroeconomic stability and growth. Many of these LLMICs are thus considering and implementing improvements to their monetary policy frameworks. The recent successes of some LLMICs and the experiences of emerging and advanced economies, both early in their policy modernization process and following the global financial crisis, are valuable in identifying desirable features of such frameworks. This paper draws on those lessons to provide guidance on key elements of effective monetary policy frameworks for LLMICs.

Low-income countries in sub-Saharan Africa present unique monetary policy challenges, from the high share of volatile food in consumption to underdeveloped financial markets; however most academic and policy work on monetary policy is aimed at much richer countries. Can economic models and methods invented for rich countries even be adapted and applied here? How does and should monetary policy work in sub-Saharan African? Monetary Policy in Sub-Saharan Africa answers these questions and provides practical tools and policy guidance to respond to the complex challenges of this region. Most countries in sub-Saharan Africa have made great progress in stabilizing inflation over the past two decades. As they have achieved a degree of basic macroeconomic stability, policymakers are looking to avoid policy misalignments and respond appropriately to shocks in order to achieve stability and growth. Officially, they often have adopted "money targeting" frameworks, a regime that has long disappeared from almost all advanced and even emerging-market discussions. In practice, though, they are in many cases finding current regimes lacking, with opaque and sometimes inconsistent objectives, inadequate transmission of policy to the economy, and difficulties in responding to supply shocks. Monetary Policy in Sub-Saharan Africa takes a new approach by applying dynamic general equilibrium models suitably adapted to reflect key features of low-income countries for the analysis of monetary policy in sub-Saharan African countries. Using a progressive approach derived from the International Monetary Fund's extensive practice and research, Monetary Policy in Sub-Saharan Africa seeks to address what we know about the empirics of monetary transmission in low-income countries, how monetary policy can work in countries characterized by underdeveloped financial markets and opaque policy regimes, and how we can use empirical and theoretical methods largely derived in advanced countries to answer these questions. It then uses these key topics to guide policymakers as they attempt to adjust food price, terms of trade, aid shocks, and the effects of the global financial crisis.

Rwanda: Selected Issues

Do changes in monetary policy affect inflation and output in the East African Community (EAC)? We find that (i) Monetary Transmission Mechanism (MTM) tends to be generally weak when using standard statistical inferences, but somewhat strong when using non-standard inference methods; (ii) when MTM is present, the precise transmission channels and their importance differ across countries; and (iii) reserve money and the policy rate, two frequently used instruments of monetary policy, sometimes move in directions that exert offsetting expansionary and contractionary effects on inflation—posing challenges to harmonization of monetary policies across the EAC and transition to a future East African Monetary Union. The paper offers some suggestions for strengthening the MTM in the EAC.
