PARIS: While the explosion of debt is throwing a shadow over global economic growth, experts warn that sub-Saharan Africa, where several countries are already in default, is experiencing its worst-ever crisis.

The rise in interest rates and over-indebtedness is already crimping the ability of countries to finance their development, as a number of African leaders emphasised at appearances at the World Economic Forum in Davos.

Following the 20072009 global economic crisis central banks in industrialised countries have generally kept interest rates low and countries from the Global South, which had mostly beenborrowing bilaterally or from international financial institutions, gained unprecedented access to financial markets.

`Many developingcountries in a desperate need for cash injection in their economies rushed to these low-cost loans, in markets with no rules or regulation,` said Kenyan economist Attiya Waris, who also serves as an independent expert for the United Nations.

She added that the International Monetary Fund had encouraged them to do so.

The money helped provide a much-needed boost to many African economies, but countries dependent upon the export of raw materials such as oil, minerals and wood came under intense pressure when commodity prices began falling in 2015.

The Covid pandemic further aggravated the situation.
