Appetite for Egypt's domestic debt has increased since the central bank floated the pound currency in November as part of an International Monetary Fund loan agreement aimed at reviving the economy.

Foreign holdings in Egyptian government securities reached 180.7 billion Egyptian pounds ($10.13 billion) as of July 4, the head of public debt at Egypt's Finance Ministry, Sami Khallaf, said.

Egypt attracted $9.8 billion in foreign investment in domestic debt instruments in the 2016-2017 fiscal year that ended in June, compared to $1.1 billion the previous year, the finance ministry said this week.
