This paper investigates the relationship between oil prices and exchange rates in three African countries using a Vector AutoRegressive (VAR) model. We use daily data on nominal exchange rates, oil prices and short term interbank interest rates from 01/12/2003 to 02/07/2014. The results suggest that the exchange rate of the three selected countries behavior is different in the event of an oil price shock, not only before and after the oil peak of July of 2008, but also between each other. Therefore, no general rule can be made for net oil importing sub-Saharan countries, such as Botswana, Kenya and Tanzania. We conclude that after an oil price peak, the Botswanan pula clearly appreciates against the US dollar, the Kenyan and Tanzanian shilling.
