Rupiah Drops 1.15% as US Dollar Rises to Rp17,660

The Indonesian Rupiah’s depreciation against the US Dollar deepened during trading today, Monday (18/05/2026). According to Refinitiv data, at 10:20 WIB, the Rupiah weakened by 1.15% to the level of Rp17,660/US.Thispressurewasmoresignificantcomparedtothemorningopening, whentheRupiahopened0.97.

The current position of the Rupiah has also moved further away from the closing position of the last trading day of the previous week, Wednesday (13/05/2026), prior to the long holiday. At that time, the Rupiah closed up 0.17% at the level of Rp17,460/US$.

Pressure on the Rupiah is in line with the continued strength of the US Dollar in the global market. The US Dollar Index (DXY) at the same time was observed to have strengthened by 0.07% to the level of 99.353.

Rupiah movements today are expected to remain influenced by external sentiments, particularly the difficult negotiations between the US and Iran to end the conflict. This uncertainty has kept demand for the US Dollar as a safe-haven asset quite high.

The strengthening of the US Dollar ultimately limits the appreciation potential of other currencies, including the Rupiah. This condition leaves the Rupiah vulnerable to continued downward pressure in early week trading.
