Foreign exchange reserves rose by $50 million to $11.22 billion in the week ended April 11, the central bank said on Thursday.
The State Bank of Pakistan's reserves rose to $7.86 billion from $7.80 billion a week earlier while reserves held by commercial banks marginally fell to $3.36 billion from $3.37 billion, the bank said.
Pakistan recently received $500 million from the World Bank and $848 million from the International Monetary Fund, which was reflected in the data last week.
Foreign reserves hit a record high of $16.5 billion in October 2007 but fell to $6.6 billion in November last year, largely because of a soaring import bill.
Pakistan agreed in November to an IMF emergency loan package of $7.6 billion to avert a balance of payments crisis.
