LONDON/NEW YORK, Dec 9 (Reuters) - Holders of Ghana's international bonds will announce next week the formation of a steering committee as the West African nation heads toward a foreign debt restructuring, two sources with knowledge of the matter told Reuters on Friday.

Ghana's marketable dollar-denominated debt totals some $13.7 billion across maturities ranging from 2023 to 2061, according to Refinitiv data.

Ghana has begun restructuring its debt by rolling out a plan to swap $10.5 billion in local bonds with new ones. It had not yet announced plans for a foreign debt restructuring. (Reporting by Jorgelina do Rosario in London and Rodrigo Campos in New York; Editing by Leslie Adler)
