‘Asian regional markets rose amid improved global risk sentiment due to hopes of a US-Iran peace deal,’ said Maximilianus Nico Demus, Associate Director of Research and Investment at Pilarmas Investindo Sekuritas, in his analysis on Monday, 25 May 2026.
Senior US officials indicated that the US and Iran are close to reaching an agreement that could reopen the Strait of Hormuz. They are still negotiating key terms, with final approval from both sides likely taking several days.
Although the peace deal is not yet final, the signals have raised hopes for stability in the Middle East. Reopening the Strait of Hormuz is expected to restore oil flows and support the global economy.
Domestically, the IHSG experienced volatile movements influenced by global and local sentiment. The US-Iran deal narrative provided positive catalysts, while pressure on the rupiah exchange rate acted as a negative factor.
Meanwhile, Bank Indonesia (BI) reported a US$9.15 billion current account deficit for the first quarter of 2026, influenced by global economic dynamics affecting the Balance of Payments outlook.

Opening higher, the IHSG remained in positive territory through the first trading session. It stayed in the green zone until the close of the second session.
