Foreign exchange reserves fell to $16.34 billion in the week ended March 2, compared with $16.42 billion in the previous week, the central bank said on Thursday. Reserves held by the State Bank of Pakistan (SBP) fell to $11.90 billion from $12.06 billion a week earlier, while those held by commercial banks rose to $4.44 billion, compared with $4.36 billion the previous week. "The decrease in SBP's forex reserves are due to scheduled debt repayments," said Syed Wasimuddin, chief spokesman of the central bank.
