Why invest in Indonesia? Most answers are written for a fund manager: a population of more than 280 million, a growing middle class, a young workforce. True, and useless to a manufacturer choosing between Medan, Rayong and Bac Ninh. A factory does not sell to a demographic. It buys feedstock, pays wages, draws power, ships under a tariff schedule and lives inside a licensing regime. Those are the lines on which Indonesia has to win or lose.

This page argues seven reasons on those lines, each with a sourced number, then lists what the seven do not fix. We develop an industrial estate in North Sumatra, so we are not neutral, and we live with the answer long after the investment committee has moved on.

Why Invest in Indonesia: What the Usual List Misses

The consultancy list is not wrong; it is aimed at the wrong buyer. Foreign direct investment into Indonesia reached Rp900.9 trillion in 2025 inside a total realisation of Rp1,931.2 trillion, and the sector and source-country breakdown in our guide to foreign direct investment in Indonesia shows where it went: metals downstreaming, logistics and digital infrastructure. Very little of that capital arrived because of the middle class; it arrived because an ore body, a policy or a tariff made processing here the cheapest option. The seven reasons below are the structural forces behind that pattern, in the order a site-selection team meets them.

Reason 1: The Feedstock Is Already Here

Resource proximity is the first manufacturing-specific reason. Indonesia mined an estimated 2.6 million tonnes of nickel in 2025, two thirds of the world total of 3.9 million tonnes, and holds 62 million tonnes of roughly 140 million tonnes of global reserves, according to the USGS Mineral Commodity Summaries 2026. It produced 51.66 million tonnes of crude palm oil in 2025, as our crude palm oil guide sets out. North Sumatra adds rubber, cocoa, coffee and fisheries.

For a processor, proximity to feedstock removes a freight leg, a currency exposure and a supply risk at once. An oleochemical plant in Medan buys CPO from mills a few hundred kilometres away; the same plant in Rotterdam buys it after a voyage of several weeks and a deforestation due-diligence file. The reason works only for industries whose input is heavy relative to its value: oils, metals, pulp, rubber, fish. An electronics assembler gains nothing from a nickel mine.

Reason 2: Downstreaming Is Policy, Not Preference

Indonesia has decided, by regulation, that its raw materials will be processed onshore. Nickel ore exports were banned from 1 January 2020, and the value of nickel exports rose from Rp17 trillion in 2014 to Rp326 trillion in 2021, a figure the President cited in the December 2022 statement that also announced the bauxite ore ban from June 2023.

The downstreaming roadmap to 2040 targets US$618 billion of investment across 28 commodities, with palm oil, rubber and coconut listed beside the metals, and aims to lift the downstream share of investment from 21% to 50% in 2025 to 2029, according to the Ministry of Investment’s published targets. BPS data for 2025 show base-metals manufacturing growing 15.17% against 5.3% for manufacturing as a whole.

For a manufacturer this is pressure and opportunity at once: a plant abroad that runs on Indonesian raw material will find it harder to buy, while the incentives, gas pricing and estate licensing follow the roadmap’s priority sectors. Put the processing step here and export the intermediate, not the ore or the oil.

Reason 3: Labour Cost Sits Between Vietnam and China

The wage differential is real but narrower than the brochures claim. The table compares statutory minimum wages in the manufacturing regions a site-selection team would shortlist, converted at early October 2026 rates.

Conversions: about Rp17,900, 33.5 baht and 6.69 yuan to the US dollar; Vietnam at the publisher’s November 2025 rate. Medan’s floor is about 36% below Shenzhen’s and 22% below Bangkok’s, and about 20% above Vietnam’s Region I.

Three caveats. Minimum wages are floors, and overtime rules and social contributions differ by country. Indonesian floors are reset every December by formula, and North Sumatra’s rose 7.9% for 2026, so a ten-year model needs a wage-growth line. And unit labour cost is wage divided by productivity, so the advantage is strongest where the work is labour-intensive and the feedstock is local. Wages are one line of seven, and our guide to the cost of doing business in Indonesia adds land, power, gas, water and freight to the same stack.

Reason 4: Treaty Access Is Widening

A plant in Indonesia ships into a widening set of treaties. The ASEAN Trade in Goods Agreement gives tariff-free access across the ten member states. RCEP has applied to Indonesia since 2 January 2023, covering ASEAN plus China, Japan, Korea, Australia and New Zealand.

The Indonesia-EU CEPA was scheduled for signing by the end of October 2026, with entry into force targeted for January 2027 and EU duties to be eliminated on 98.5% of tariff lines, according to the Trade Minister on 6 October 2026. With the United States, the Agreement on Reciprocal Trade signed in February 2026 fixes a 19% tariff on Indonesian goods with zero rates for selected lines: the rate the July 2025 tariff order also set for Thailand, Malaysia and the Philippines, one point below Vietnam.

Behind the treaties sits a domestic market large enough to absorb a plant’s output when export demand wobbles, which Vietnam cannot offer. Market access is now comparable to ASEAN peers, and the EU agreement would put Indonesia ahead of most of them; neither was true five years ago.

Reason 5: Energy Is Priced by Policy

Indonesia produces its own gas and coal and uses policy to price them for industry. The certain natural gas price scheme, HGBT, sets pipeline gas at about US$6.5 per MMBTU for seven sectors: fertiliser, petrochemicals, oleochemicals, steel, ceramics, glass and rubber gloves. In June 2026 the Deputy Minister of Energy and Mineral Resources, Yuliot Tanjung, confirmed there would be no increase for the year. For an oleochemical or glass plant, gas at that level against spot LNG is a structural advantage, not a cyclical one.

Two caveats. Eligibility is by sector and plant, allocation is contested when supply is tight, and the decree can change. And the grid is coal-heavy, which matters if your customers audit Scope 2 emissions.

Reason 6: The Investment Regime Is More Open Than It Was

The 2021 Positive Investment List reversed the old logic: a sector is open to 100% foreign ownership unless it is listed as closed or conditional, and most manufacturing codes are open. A foreign company invests through a PT PMA with total investment above Rp10 billion per five-digit KBLI per location, excluding land and buildings, licensed through the OSS risk-based system under Government Regulation 28 of 2025. The PT PMA holds land under HGB, not freehold, and inside an estate the practical route is HGB over the developer’s title.

Tax holidays and allowances exist for pioneer industries, but the Ministry of Finance grants them against conditions, never an estate, and the registration windows change. The regime is not frictionless. It is predictable enough to model, which it was not under the old Negative List.

Reason 7: Geography, and the Infrastructure Cycle Behind It

Indonesia sits on the Strait of Malacca, through which 102,525 vessels over 300 gross tonnes passed in 2025, about 281 a day, as our Strait of Malacca shipping route guide sets out. A plant on the Sumatran shore is a day’s sailing from Singapore and Port Klang, on the direct route to China, Japan and India.

The geography is old; the infrastructure cycle built on it is new: the Trans Sumatra toll road, the Kuala Tanjung and Patimban port programmes, and the Ministry of Transportation’s target to cut logistics cost from 14.29% of GDP to 8%. That target is also this list’s honest admission: the geography is a reason to invest, and today’s logistics cost is the reason to choose the site carefully. Our landed-cost model for a port-integrated estate shows what 5, 30 and 100 km from a berth cost one tenant a year.

What the Seven Reasons Do Not Fix

A list that counts only the upside is marketing, so here is the other column.

• Logistics cost. About 14.29% of GDP, a 2023 Logistics Performance Index score of 3.0 against Malaysia’s 3.7, and import dwell time averaging 3.02 days at the main ports in 2025. The treaties lower the tariff at the border; they do not shorten the road to it.
• Permits. The written licensing timeline and the practical one differ. Our guide to doing business in Indonesia covers it without pretending it closes.
• Land. Acquisition outside an estate is slow and title documents vary parcel by parcel. Inside an estate the developer carries that risk, which is the main thing an estate sells.
• Policy change. Export levies, domestic market obligations and wage formulas move every year. Model them as variables, not constants.

Where SIIPE Fits

SIIPE (Sumalacca Integrated Industrial and Port Estate) is a planned 5,600-hectare integrated industrial estate, deep seaport and township in Medan Belawan, North Sumatra. Around 840 hectares has been acquired; 4,760 hectares remains to be acquired or reclaimed. The current development phase covers 3,000 hectares: 1,800 ha industrial estate, 400 ha deep seaport and 800 ha residential township.

Of the seven reasons, SIIPE is built around three. Feedstock: North Sumatra’s palm oil, rubber and fisheries are the estate’s target sectors. Downstreaming: the masterplan allocates plantation processing and refining plots, the step the roadmap wants onshore. Geography: the site is 4.7 km from Belawan Port, about 10 minutes by road, and the masterplan puts every plot under 5 km from the estate’s own berth at the Sumalacca Dry & Liquid Bulk Port, which is planned, not operational.

SIIPE does not offer the operational readiness of an established Java estate today. Estate utilities are planned, and the application for special economic zone and free trade zone status is in process and has not been granted. We welcome 100% foreign investment, subject to your sector’s position on the Positive Investment List.

Frequently Asked Questions

Why invest in Indonesia rather than Vietnam?

Vietnam wins on wage floors and on operational readiness today. Indonesia wins where the plant processes a local raw material, because feedstock proximity and the downstreaming policy remove freight and supply risk, and where the domestic market matters as a hedge. Treaty access is now broadly comparable between the two.

What is the minimum wage for manufacturing in Indonesia in 2026?

Minimum wages are set by province and regency each December. For 2026, Medan’s floor is Rp4,335,198 a month and North Sumatra’s provincial floor is Rp3,228,971, up 7.9% on 2025. At about Rp17,900 to the US dollar, those are roughly US$242 and US$180 a month before overtime and contributions.

Can a foreign manufacturer own 100% of its Indonesian plant?

In most manufacturing sectors, yes. The 2021 Positive Investment List opens a sector to full foreign ownership unless it is listed as closed or conditional. The vehicle is a PT PMA with total investment above Rp10 billion per business line per location, and it holds land under HGB rather than freehold.

What is Indonesia’s downstreaming policy?

Downstreaming, or hilirisasi, requires raw materials to be processed in Indonesia before export. Nickel ore exports have been banned since January 2020 and bauxite since June 2023, and the roadmap to 2040 targets US$618 billion of investment across 28 commodities, including palm oil, rubber and coconut as well as metals.

Does Indonesia have a free trade agreement with the European Union?

Not in force yet. The Indonesia-EU Comprehensive Economic Partnership Agreement was scheduled for signing by the end of October 2026 and is targeted to enter into force in January 2027, when the EU is expected to eliminate duties on 98.5% of tariff lines.
