The Sri Lankan rupee hit a record low for a second day running on Friday due to dollar demand from banks and importers, but remittances and greenback sales by exporters checked the fall, dealers said. The spot rupee ended at 154.30/35 per dollar, surpassing the previous low of 154.28 hit on Thursday, when it closed at 154.15/20. The currency fell 0.4 percent this week, surrendering a 0.2 percent gain made last week.
