TEMPO.CO, Jakarta - Bloomberg Dollar Index said the rupiah fell 6 points or 0.04% to Rp14.176/USD in the opening Friday, September 4. On Thursday, the rupiah closed down 33 points or 0.23% to Rp14.170 per US dollar.
The rupiah weakened as US employment data increased, triggering market worries that the Federal Reserve will soon raise interest rates. The Fed Meeting will be held 16-17 September 2015.
On Thursday, the US dollar index closed up 0.6% to 96.405. The dollar strengthened after the European Central Bank (ECB) expanded the scope of their stimulus program.
ECB President Mario Draghi signalled policy makers that they can increase stimuli to counter the risk of slower growth. The decision pushed the dollar index to rise to its highest level since August 12, 2015.
"It [was triggered by] Draghi's speech," said Bart Melek, Head of Commodity Strategy TD Securities as quoted by Bloomberg, on Friday.
NH Korindo Securities Indonesia (NHKSI) estimated that Bank Indonesia middle rate of the rupiah exchange rate to the US dollar in trading Friday, will reach its weakest point at Rp14.172.
