Saudi Arabia's government has asked banks to discuss providing it with a major international loan that could total around $10 billion, sources aware of the matter said Wednesday.

The government sent an invitation to banks to discuss the loan, the sources said, declining to be identified because the matter is not public.

The invitation did not specify the size of the loan, but the sources said they believed it could be around $10 billion, or possibly more.

Calls to the Saudi finance ministry and central bank seeking comment after hours Wednesday were not answered.
