HSBC has re-opened its representative office in Libya, and staff employed there have returned to work.
The bank closed the office in February as a result of the unrest.
HSBC's representative office was first established in 2006, although the bank's presence in Libya goes back almost 60 years, having opened its first branch in Tripoli in 1952.
The primary purpose of the representative office in Libya is to provide advice, assistance and services to domestic Libyan institutions and multinational clients with business interests in Libya, and provide financial advice on project, infrastructure and trade finance.
"This is a significant development, and we are delighted to reopen our doors in Tripoli," HSBC Libya CEO Timothy Gray said.
"We look forward to playing our part in working with the new authorities and helping to return Libya to stability and growth."
