The currency traded in inter-bank transactions at 9,624 to the dollar weakening losing 9 points from the level of 9,615 earlier.
Trust Securities` analyst Reza Priyambada attributed the rupiah fall to negative sentiment from Spain and lack of aggressiveness in the Fed policy.
Reza said Spain was reported to soon propose for bailout fund but realization is expected only by the end of October after regional election in that country and the European Union summit meeting on Oct. 18.
Meanwhile, Milenium Danatama Sekuritas` analyst Abidin said rupiah still has room for strengthening against the US dollar with foreign capital continuing to flow into the country. (*)
