Understanding SLL / US$ exchange rate dynamics in Sierra Leone using Box-Jenkins ARIMA approach


  • Jackson, Emerson Abraham


This study was carried out with the purpose of producing twelve out-of-sample forecast for a univariate exchange rate variable as a way of addressing challenges faced around dollarization issues in the domestic economy. In pursuit of this, the ARIMA model was utilised, with the best model [1,4,7] indicating that the Sierra Leone - Leone [SLL] currency will continue to depreciate against the United States Dollar [US$] throughout most part of the year 2020. This was done on the assumption of Ceteris Paribus condition, and most importantly on the view that past events of the univariate exchange rate variable is a determinant of future outcomes or performances. In a bid to moving forward, policy recommendations have suggested high level collaboration between relevant policy institutions like the Bank of Sierra Leone and the Ministry of Finance to address issues of concern, for example, a boost to the real sector and many more.
