Market analyst Rully Arya Wisnubroto of publicly-listed state lender PT Bank Mandiri (Persero) Tbk said that the rupiah's exchange rate on Friday was influenced by external factors.
"External factors dominated (the movement of the rupiah's exchange rate), particularly after the presidential election and the meeting of Bank Indonesia's board of governors," Wisnubroto said.
The external factors included better-than-expected US economic data, he said, adding that investors are currently awaiting the release of US gross domestic product (GDP) data.
"Looking ahead, it seems that the rupiah would remain stable at a range of Rp14,100 to Rp14,200 per dollar. There has been no significant change yet," he said.
