KARACHI (Reuters) - The Pakistani rupee fell to a record low on Wednesday because of increased dollar demand for import payments, especially for oil, dealers said. A currency dealer said the rupee traded as low as 86.29, beating the previous record low of 86.25 the previous day. The rupee ended at 86.24/29 to the dollar, compared with Tuesdays close of 86.22/28. Dealers expect the local unit to weaken further.
