“Sudan will be, by 3 1/2 times, the largest HIPC case,” Baker said. “The total amount of debt relief expected to be delivered at the completion point, the end of the HIPC process, is $50 billion.”

Altogether, Sudan’s external debt burden is expected to fall from about $56 billion, or 163% of gross domestic product as of the end of 2020, to $6 billion 14% once the completion point is reached and with the participation of all creditors, the IMF said in a statement.

The extended credit facility will last for 39 months, Baker said.

Sudan, where long-time dictator Omar al-Bashir was ousted amid a 2019 popular uprising, is racing to turn around an economy wrecked by decades of mismanagement, sanctions and isolation from global markets. Inflation hit 379% in May as authorities enact a re-balancing of the currency and battle shortages of key commodities.

Finance Minister Gibril Ibrahim told Bloomberg this month that Sudan is seeking to clear 70%-90% of its overseas debt in the near future, with the remaining commercial arrears taking longer.

Earlier, the U.S. Treasury Department said the U.S. aided Sudan in clearing some $1.4 billion of arrears to the IMF.

It provided Sudan same-day bridge financing of about $1.15 billion in March, at no cost to U.S. taxpayers, the Treasury said in a statement.

“These steps will unlock much-needed financing and will help build the foundation for poverty reduction, inclusive development, and economic growth,” Treasury Secretary Janet Yellen said.
