The impact of financial crises on the exchange markets in the Maghreb countries using the Shannon entropy method

Abstract

This study investigates the effect of financial crises on exchange markets, using the Shannon
Entropy method for different exchange rates in the Arab Maghreb countries during the period
from 2005 to 2017. It was found, through the study, that the periods in which the entropy values
take their lowest value, are considered as an indication of the occurrence of a financial crisis. As
has been reached, that before the financial crisis strikes, entropy takes its highest value, which is
the value that is considered as an early warning system that gives preliminary information
before the crisis occurs.
