In 1955, he graduated with a Bachelor of Arts degree in Economics
and later, in 1959, he received his Masters of Arts degree. Immediately
after graduating with his BA, he started his training at the Midland
Bank in London.
Enriched by his life and education abroad, Khalid returned to
Jordan a year later to work next to his father and his older brother,
Abdul Majeed, in developing the growing Arab Bank. In 1956, Khalid
was appointed Assistant Deputy General Manager and, in 1957, he
was elected a member of the Board of Directors of the Arab Bank.
Shortly thereafter, the Bank went through a difficult period:
it had to cope with the nationalization of several of the Bank's
branches in numerous Arab countries and with the aftermath of
the 1967 Arab-Israeli war.
