I am currently doing a research work on quantitative easing and can't find any example in Africa. Do you know of any African central bank that has ever used QE?
Thanks for your help and sorry for the bad english (still learning)
For Quantitative Easing to happen, a central bank needs to expand its balance sheet by, more or less, "printing money" from scratch. Quantitative Easing is a difficult policy in that you want to encourage inflation to force investment, but at the same time you need to control that inflation. For this reason QE should be used only when central banks believe economy is growing slower than it could/should be, which does not happen a lot in Africa.
For QE to be efficient, you need a strong central bank/currency, ie printing new dollars will create more dollars, but printing new 1920s Deutschmarks will only bring down the value of an individual Deutschmark.
To my knowledge, the only African country that wandered in Quantitative Easing is Zimbabwe. The success of this policy may by itself discourage any other comparable country to engage in such a policy.
QE is a last resort policy for stalling economies. Japan, Western Europe and the USA are countries where QE has been widely discussed because it is sometimes believed investment is delayed in hope of better days - QE should prevent this, but this is not a typically african problem, to my knowledge.
TL;DR: Even if African central banks were strong enough to engage in QE, African economies don't need such a policy to date.
Quantitative easing (QE) is an historically unusual monetary policy tool that involves the purchase of financial assets by the central bank. Unlike similar assete purchases used for moving exchange rates, these assets are typically local currency denominated and not sterilized. Although central bank purchase of government debt occurs in both QE and monetization (like what occurred in Zimbabwe and the Weimar inflation), they are actually quite different. Under QE asset purchases are usually expected to be temporary and accumulated assets (money) ultimately resold (returned in exchange for assets). Monetization has neither expectation.
QE is typically been employed as a way of increasing the monetary base when interest rates at or close to the zero lower bound and therefore conventional monetary policy tools like changing the federal funds rate are (thought to be) ineffective. Many African countries are poor candidates for QE because they have pegged currencies, participate in a currency union, or have high inflation.
