Indonesian share prices closed down 1.66 percent on Wednesday as the rupiah fell to its lowest level since April 2002, while record oil prices sparked concerns about a growing state budget deficit, dealers said.
The Jakarta Stock Exchange composite index closed down 12.160 points at 719.042 on volume of 1.05 billion shares worth 1.05 trillion rupiah (113.3 million dollars).
