KARACHI (Reuters) - The rupee fell to a record low on Tuesday because of increased dollar demand for import payments, especially of oil, dealers said. A currency dealer said the rupee traded as low as 86.25, beating the previous record low of 86.07 made the previous day. The rupee ended at 86.22/28 to the dollar, compared with Mondays close of 86.10/14. Dealers expect the local unit to weaken further.
