Indonesian Manufacturing Surges and Economy Grows 5 Percent Amidst Global Oil Volatility: What is the Strategy Safeguarding the National Trade Surplus?

The Indonesian economy entered the fourth quarter of 2026 with a series of indicators pointing toward positive developments. Manufacturing activity, as measured by the S&P Global Purchasing Managers’ Index (PMI), rose sharply to 54.0 in October 2026, up from 52.4 in September. This achievement indicates increasingly robust expansion in the manufacturing sector, marking the highest level since March 2024. Concurrently, monthly inflation eased to 0.22%, compared to 0.30% in September.

On the trade front, Indonesia recorded a trade surplus of US$3.36 billion in September 2026. Although still in surplus territory, the value was lower than the US$3.55 billion recorded in the previous month. The Central Statistics Agency (BPS) noted exports reached US$27.59 billion, while imports stood at US$24.23 billion. Year-on-year, exports grew by 11.87%, while imports surged at a much higher rate of 18.41%. This glaring divergence in growth rates highlights that increased economic and manufacturing activity is accompanied by a massive appetite for imported goods.

This trade condition warrants close attention, as import growth from January to September 2026 reached 19.67%, far outpacing export growth, which stood at a mere 5.58%. Nevertheless, the processing industry remains the backbone of exports. In September 2026, the export value of the processing industry hit US$23.27 billion, equivalent to 87.36% of total non-oil and gas exports. This development underscores the sector's massive contribution to foreign trade while simultaneously signaling that manufacturing expansion must be matched by the ability to efficiently source raw materials and capital goods.

Before the official September data release, economists had widely predicted a shrinking trade surplus due to surging imports. Bank Mandiri's Chief Economist estimated a surplus of US$2.25 billion, while BCA's Chief Economist David Sumual projected an even lower surplus of US$1.52 billion.Both projections factored in a spike in imports driven by supply recoveries from several Asian countries and a 15.8% month-on-month jump in Brent crude oil prices. On the export side, an 11.7% increase in coal prices to export side, an 11.7% increase in coal prices to US$146 per ton and rising demand from key trading partners provided critical support. Ultimately, the actual US$3.36 billion surplus significantly outperformed both economists' expectations.

Amidst trade dynamics and external pressures, domestic demand remains a steadfast pillar of Indonesia's economic growth. Based on data presented by innovation and public policy observers, the Indonesian economy grew by 5.61% in Q1/2026 and 5.29% in Q2/2026. Growth prospects for the entirety of 2026 are also projected to remain above 5%. The IMF estimates 5.1% growth, while the World Bank projects 5.2%. However, global energy price pressures remain a structural vulnerability, primarily because Indonesia still imports approximately one million barrels of oil per day.

In terms of fiscal policy, the government has committed to maintaining subsidized fuel prices—namely Pertalite and Biosolar—through the end of 2026. This policy is viewed as a vital mechanism utilizing the State Budget (APBN) as a shock absorber to cushion public purchasing power against global energy price hikes. Meanwhile, manufacturing and investment activities show positive momentum. Bank Indonesia's PMI in Q3/2026 was recorded at 52.28, while realized investments reached Rp528.7 trillion. Bank credit disbursement grew by 13.26% annually, with investment credit surging by 23.20%. These indicators prove the presence of strong financing activity and business capacity expansion despite global economic headwinds.

Public consumption activity further underpins the economy. Electronic money transactions reached Rp226.47 trillion in July–August 2026, while QRIS transaction volume in Q3/2026 skyrocketed by 75.80%. Furthermore, national and international events continue to drive regional economic circulation. The Mandalika MotoGP in October 2026 alone was estimated to generate a multiplier economic impact of approximately Rp5 trillion. However, optimism regarding economic growth must be tempered. An LPEM UI survey in the second half of 2026 revealed that 52% of 63 economists assessed that economic conditions had worsened compared to three months prior.

These diverse indicators demonstrate that the Indonesian economy possesses multiple engines of growth, spanning manufacturing, investment, consumption, and fiscal policy support. However, imports massively outpacing exports, reliance on specific commodities, and global energy price pressures remain structural risks that demand acute attention. For the business world, these conditions highlight the critical necessity of maintaining production cost efficiency, reinforcing supply chains, and meticulously managing raw material procurement and financing.

Looking ahead, the government must fiercely guard price stability and public purchasing power while aggressively strengthening domestic industrial competitiveness, ensuring that increased production translates into higher exports and robust job creation. Business actors, in turn, must capitalize on domestic growth opportunities by elevating productivity and anticipating volatile import costs. By executing on these fronts, economic growth will transcend mere statistical achievements and deliver broad, sustainable benefits to society and the business landscape alike.
