KARACHI (Reuters) - Pakistans foreign exchange reserves rose to $14.94 billion in the week ending on March 27 from $14.81 billion the previous week, the SBP said Thursday. Reserves held by the State Bank of Pakistan (SBP) rose to $11.03 billion from $10.90 billion a week earlier, while those held by commercial banks were flat at $3.91 billion, said SBPs chief spokesman Syed Wasimuddin. Pakistans foreign reserves hit a record high of $16.5 billion in October 2007 but fell steadily to $6.6 billion by November 2008, largely because of a soaring import bill.
