Indonesian Manufacturing Rebounds as Export Demand Powers Fastest Expansion Since February

JAKARTA, Investortrust.id — Indonesian manufacturing activity mounted a decisive recovery at the close of the third quarter, breaking out of a brief contraction on the back of accelerating export demand and cooling raw-material costs.

The headline S&P Global Indonesia Manufacturing Purchasing Managers’ Index (PMI) climbed to 52.4 in September from 49.8 in August, crossing back above the 50.0 no-change threshold. The turnaround marked the sharpest overall improvement in Indonesian operating conditions since February, underpinned by positive contributions across all five survey subcomponents.

Southeast Asia’s largest economy is navigating complex external headwinds, from high global borrowing costs to persistent geopolitical friction that has kept energy prices volatile. Sustained factory expansion demonstrates that real-economy production and cross-border trade flows remain intact despite financial market turbulence. With customer demand clearing out finished warehouse inventories and swelling uncompleted order books, the sector enters the final stretch of the year with a durable operational buffer.

Export Demand Sparks Broad Production Rebound

September's manufacturing upswing was anchored by a broad revival in commercial demand. The volume of incoming new orders expanded at the quickest pace in seven months, reflecting new customer project commencements and improving purchasing power across core client bases.

Foreign sales provided critical momentum. Outbound export orders rose for a second consecutive month, expanding at the steepest pace recorded since May 2022.

The influx of customer commitments prompted factories to reverse July's production dip, lifting manufacturing output at the fastest rate since February. To satisfy mounting delivery commitments, producers drew aggressively down on their stockpiles, depleting inventories of finished goods at the fastest pace seen since August 2020.

"The near-term outlook for production looks promising, as backlogs increased the most in five years in September despite the strongest rise in employment since early-2025," said Trevor Balchin, Economics Director at S&P Global Market Intelligence. "Manufacturers sold from existing stock to meet orders as inventories of finished goods fell at the strongest rate in just over six years."

Capacity Pressures and Job Creation

Faced with heavier order books, factory floors added headcount to relieve capacity strain. Employment expanded at its fastest pace since February 2025, marking only the third round of manufacturing job creation in 2026.

Despite the addition of production staff, outstanding business volumes mounted rapidly. The backlog of unfinished orders surged at the fastest rate in five years, underscoring that current factory capacity is running close to its limits to keep pace with order inflows.

Cost Pressures Moderate to Six-Month Low

Factory floor margins gained breathing room as supply-side inflation eased. Input price inflation decelerated to its lowest rate in six months, though overall input costs remained above the historic survey average due to currency movements, raw material costs, and fuel policy revisions.

In response, factory gate charges moderated in tandem, with output price inflation easing to a six-month low.

The cooling of cost pressures prompted manufacturers to step up their procurement activities, expanding purchasing volumes at the fastest rate since February. Inventories of raw materials and production inputs increased at the quickest rate since March 2024, reversing the steady inventory depletion observed between April and July. Supply chains held relatively stable throughout the month, with delivery lead times lengthening only marginally.

Survey data showed domestic manufacturers maintain strong confidence regarding the business environment over the coming year. Sentiment was supported by planned corporate expansions, pipeline customer projects, and hopes for greater raw material price stability heading into 2027.
