The country's foreign exchange reserves rose by $90 million to $13.507 billion in the week ending on March 17, the central bank said on Saturday.
Reserves held by the State Bank of Pakistan (SBP) reached a high of $11.245 billion, up from $11.179 billion a week earlier, and those held by commercial banks were $2.262 billion, up from $2.238 billion, SBP said in a statement.
Officials said reserves had grown over the past few weeks because of rising foreign investment inflows and higher remittances from Pakistanis abroad.
Foreign direct investment rose more than 95 percent to $2.97 billion in the first eight months of the 200607 fiscal year (July-June), led by inflows into the financial, communications and energy sectors, official figures show.
Inflows from foreign portfolio investment during July-February were $981.2 million, up from $470.9 million in the corresponding period last year.
