The Jakarta Composite Index (IHSG) fell by more than 1% at the start of trading today, Friday (March 13, 2026). At around 09:27 WIB, the index had declined by 1.06% to a level of 7,284.41.

A total of 463 stocks recorded declines, while 151 shares advanced and 344 remained unchanged. The total trading value reached Rp2.19 trillion, involving 5.2 billion shares across 321,800 transactions.

The movement of the IHSG this morning mirrored the trend in other Asian markets. Australia’s S&P/ASX 200 slipped about 0.3% during early Asian trading, while Japan’s Nikkei 225 dropped by 2% and the broader TOPIX index declined by around 1.4%.

In South Korea, the benchmark KOSPI index plunged nearly 3%, while the small-cap KOSDAQ index fell by almost 2%.

This decline occurred as investors grew increasingly concerned about oil supply disruptions amid a conflict expected to last for an extended period.

Global oil prices have surged by more than 38% in less than two weeks due to serious threats to global supply routes.

Brent Crude Oil rose to US$100.72 per barrel, while West Texas Intermediate (WTI) stood at US$95.37 per barrel.

The price surge was triggered by attacks on two oil tankers and oil port facilities in Iraqi waters, raising concerns about the safety of navigation in the Strait of Hormuz. Iran’s military even warned that oil prices could potentially soar to US$200 per barrel.

In another development, amid large-scale military operations launched by the United States and Israel, U.S. intelligence assessments indicate that Iran’s current leadership structure remains intact and far from collapse. The report emphasized that the regime in Tehran continues to maintain firm control over its population.

The position of supreme leader has reportedly been taken over by the son of Ali Khamenei, namely Mojtaba Khamenei, in order to preserve political stability. Meanwhile, an Iranian Kurdish militia group had offered support for a rebellion, but the option was rejected by U.S. President Donald Trump after intelligence agencies questioned the group’s military capabilities.

According to the latest reports, Mojtaba stated in his first public address since being chosen as Iran’s supreme leader that the Strait of Hormuz must remain closed. This measure is intended to use the strait as leverage to pressure adversaries.
