JCI Expected to Consolidate as Market Awaits Inflation Data Release

RRI.CO.ID, Jakarta - The Jakarta Composite Index (JCI) on the Indonesia Stock Exchange (IDX) is expected to consolidate during trading on Tuesday, September 1, 2026. On Monday, the JCI closed 0.11 percent higher at 6,525.

However, the end‑of‑August session still saw foreign investors selling shares worth IDR 710.56 billion. The stocks most heavily sold by foreign investors were CPIN, EMAS, BUKA, UNVR, and ASII.

Nevertheless, according to Phintraco Sekuritas, the JCI rose 4.64 percent month‑to‑month (mtm) throughout August. From January to August 2026, the index has corrected by 24.53 percent year‑to‑date (ytd).

“For today, from a technical perspective, the JCI is expected to consolidate within the 6,450–6,570 range,” the Phintraco Analyst Team said on Tuesday, September 1. Market participants are awaiting Indonesia’s inflation data, which the Central Bureau of Statistics (BPS) will release today.

The Phintraco team forecasts a 0.2 percent increase in inflation for August. Previously, in July 2026, Indonesia recorded a 0.14 percent deflation.

“Consequently, the estimate is that the annual inflation rate in August 2026 will rise to 3.13 percent from 2.88 percent in July,” the team stated.

Meanwhile, the trade balance is projected to record a USD 300 million deficit in July 2026, narrowing from a USD 450 million deficit in June 2026.

The manufacturing Purchasing Managers’ Index (PMI) is estimated to edge up to 50.5 in August 2026, from 50.2 in July.

Globally, market participants will monitor the impact of US strikes on Iranian territory, which have triggered another increase in global oil prices. “If oil prices remain elevated for an extended period, this could push inflation higher again,” the Phintraco team said.

At the same time, the US Federal Reserve has signaled a stronger focus on bringing inflation down to its 2 percent target. “This further strengthens expectations that the Fed will raise interest rates in September,” the Phintraco team concluded. (Gusti Panji)
