The Macron-Ouattara announcement represents a needed reform. But it is just one of many that needs to happen. Going forward, the challenge will be to keep the benefits of the CFA franc monetary zone, namely a stable currency and low inflation, while transitioning to a new institutional system away from France. A monetary system that holds a former colonial power as the guarantor, regardless of announcements or agreements, will always ultimately fail to eradicate neocolonialism.
