KARACHI (Reuters) - Pakistans foreign exchange reserves rose to $17.20 billion in the week ending Oct. 14 from $17.17 billion the previous week, the central bank said on Thursday. Reserves held by the State Bank of Pakistan (SBP) were flat at $13.46 billion, while those held by commercial banks rose to $3.74 billion, from $3.71 billion in the previous week, according to the State Bank of Pakistan. Foreign exchange reserves hit a record $18.31 billion in the week ending July 30 but have eased due to debt repayments. The reserves were boosted in June by inflows of $411 million, including a $191.9 million loan from the World Bank, and a loan of $196.8 million from the Asian Development Bank. Higher export proceeds and a record inflow of remittances have helped Pakistans forex reserves grow steadily. According to official data, remittances rose 25 percent to $3.3 billion in the first three months of 2010/11 fiscal year (July-June), compared with $2.65 billion in the same period last year. However remittances fell to $890 million in September, compared with $922 million received in September last year.
