The rupiah weakened in the spot market. According to data compiled from Investing.com, the US dollar exchange rate against the rupiah reached Rp17,293 at 1:30 PM WIB.
The rupiah fell by 136.8 points, or 0.80%, compared to the previous trading session.
Earlier in the morning, the currency had even touched the 17,300 level, based on data published by Bloomberg as of 10:33 AM WIB.
Citing Katadata, economist and currency and commodity observer Ibrahim Assuaibi said that both external and internal factors are believed to be driving the rupiah’s depreciation.
He noted that the rupiah’s weakening past the 17,000 level occurred faster than initially expected, which had been projected for the end of April 2026.
From the external side, geopolitical tensions involving Iran, Israel, and the United States are among the key drivers.
“In this week’s meeting between the US and Iran facilitated by Pakistan, Iran did not attend the negotiations because the US had violated the ceasefire agreement by seizing Iranian tankers passing through the Strait of Hormuz,” Ibrahim said in a statement on Thursday (April 23, 2026).
According to him, Iran has lost trust in the US and is prepared for a prolonged conflict.
The situation has been further complicated by a unilateral ceasefire claim by the US, which included conditions such as prohibiting Iran from imposing tariffs in the Strait of Hormuz and requiring uranium to be transferred and stored in the US.
“These two conditions are unlikely to be accepted by Iran, as they are part of a country’s sovereign rights and obligations. Therefore, Iran does not want to be intervened in by the US,” he added.
On the domestic side, Ibrahim pointed out that large portions of government debt are nearing maturity, which could weigh on fiscal performance.
Another recent internal factor is the government’s decision to raise prices of non-subsidized fuel while keeping subsidized fuel prices unchanged.
“Not increasing subsidized fuel prices means the government’s subsidy burden will grow, forcing it to find budget reallocations to support subsidized fuel like Pertalite. This could lead to a widening fiscal deficit again,” Ibrahim explained.
