Rupiah Weakens 0.12% to Rp 17,124 per US Dollar, Dragged by Global Inflation Surge

JAKARTA, KOMPAS.com - The rupiah exchange rate in the spot market came under pressure at the start of trading on Monday (13/4/2026). The Garuda currency opened at the level of Rp 17,124 per US dollar.

That position weakened by 0.20 points or 0.12% compared to Friday’s (10/4/2026) close at Rp 17,104 per US dollar.

Currency and commodity analyst Ibrahim Assuaibi assessed that the Garuda currency will still struggle to move away from levels above Rp 17,000 per US dollar in the coming week. In addition to geopolitical tensions in the Middle East, the rupiah’s weakening is also driven by uncertainty over the direction of US monetary policy.

“The rupiah is likely to weaken further. The rupiah’s depreciation is quite significant, and it is likely to remain above the Rp 17,000 level,” Ibrahim told reporters on Sunday (12/4/2026).

“In trading over the next week, the US dollar is likely to widen significantly. I see its support at 97.00, and resistance at 100.900. What does that mean? There is a high likelihood that the range will widen to 97,000 and 101.00. That’s if we round it off, from 100.900,” he explained.

According to him, Iran’s closure of the Strait of Hormuz is the root cause of the rupiah’s exchange rate weakening. The tightening of that narrow shipping route directly disrupts global crude oil distribution, as this route is one of the world’s main energy trade arteries.

The rise in oil prices then fuels global inflation due to higher energy costs. In this situation, central banks tend to maintain high interest rates for longer to curb inflation.

At the same time, geopolitical uncertainty prompts global investors to shift to safe-haven assets like the US dollar. The increased demand for the dollar causes the index to strengthen and the rupiah to weaken.
