Rupiah Opens Stable, US Dollar Holds at Rp16,990

The rupiah opened stagnant against the United States (US) dollar at the start of trading this week on Monday (6/4/2026). According to Refinitiv data, the Garuda currency opened trading at Rp16,990/US$, or relatively unchanged from the previous trading close on Thursday (2/4/2026). The rupiah closed weakening by 0.09% in that session. Meanwhile, the US dollar index (DXY), which measures the greenback’s strength against six major world currencies, was recorded strengthening by 0.22% to the level of 100.248 at 09:00 WIB. The rise in DXY indicates that the US dollar is still being sought by investors amid increasing global uncertainty. The rupiah’s movement this morning is still overshadowed by external sentiment, particularly the strengthening of the US dollar in global markets amid growing investor concerns over the escalating Iran war. The US dollar moved in the green zone this morning as market participants monitored the latest developments in the Iran conflict. Investors’ main focus is on the latest deadline from US President Donald Trump regarding the reopening of the Strait of Hormuz. In a social media post on Easter Sunday, Trump threatened to target power plants and bridges in Iran on Tuesday (7/4/2026) local time if that strategic route is not reopened. The market views that statement as reinforcing the risk that geopolitical disruptions could last longer. Trump’s latest ultimatum has become a negative sentiment for the market, not merely because war is certain to break out soon, but because each new threat makes the risk of disruption appear longer, deeper, and heavier for the global economy. This situation has led investors to view this conflict as an issue that could spread from oil price surges to inflation, and then to interest rates. This is the condition that makes the US dollar the primary safe-haven asset at present. Ultimately, the strengthening of the US dollar in global markets signals that investors are still hunting for dollar-denominated assets. This situation makes the room for strengthening of other countries’ currencies, including the rupiah, increasingly limited.
