Most emerging Asian currencies slid on Monday on hedge fund selling after mass euro zone sovereign rating cuts by Standard & Poor's, though some investors bought regional units on hopes for inflows to Asia.

The rupiah weakened the most among emerging Asian currencies on Monday, down 1.4 percent on the day to 9,200 per US dollar. Nasution did not give a level that he was targeting for the rupiah, but late last year the central bank appeared to be defending the currency at around 9,200 per US dollar.
