JCI Predicted to be Volatile Today Amid High Oil Prices and High Interest Rates

The Indonesia Composite Index (JCI) on the Indonesia Stock Exchange (IDX) opened weaker in trading on Wednesday, 3 June 202cap 6, facing predicted volatility. This condition is triggered by a combination of external pressures from high global oil prices and the persistence of high interest rate policies.

The Lotus Andalan Sekuritas research team, in their study in Jakarta, stated that although the short-term prospects for the Indonesian capital market show improvement, vulnerability to external factors remains very high. “The market is still vulnerable to pressures such as high oil prices, global interest rates remaining at elevated levels, and a weakening trade surplus,” wrote the Lotus Andalan Sekuritas research team on Wednesday.

Geopolitical tensions between the United States and Iran serve as a primary factor driving up energy prices. Iran’s threat to block the Strait of Hormuz has pushed global oil prices towards the 100 US dollar per barrel level, raising concerns about a new wave of global inflation.

On the other hand, the US stock market recently hit record highs on 2 June 2026, driven by euphoria in the artificial intelligence (AI) and semiconductor sectors. However, this rally is overshadowed by the risk of market concentration within a handful of giant technology stocks.

Domestically, there are positive signals from the real sector, where the Indonesia Manufacturing PMI returned to the expansion zone in May 2026. This indicates a recovery in domestic economic activity after a contraction in the previous month. However, this optimism is tempered by less encouraging macroeconomic data. In the banking sector, the phenomenon of high undisbursed loans indicates that although Rupiah liquidity remains strong, the demand for productive credit from businesses has not yet fully recovered. This combination of factors is causing investors to remain conservative towards assets in emerging markets, including Indonesia.
