SOUTHEAST ASIA'S LARGEST AND STEADILY ECONOMY
For investors, what matters when it comes down to sizing up the economy of a country are these two questions: how big is the economy, and how steadily does it grow? According to the IMF's April 2026 World Economic Outlook, Indonesia's nominal GDP ranks 17th in the world, supporting its status as the country in Southeast Asia with the largest economy. Indonesia's purchasing power parity places the country in 7th place, while the economy has seen around 5% growth in most years outside the pandemic, providing statistics that might just be the answers investors are looking for.
Indonesia's nominal GDP of ~US$1.54 trillion positions the country as the 17th largest economy in the world, placing it above many advanced and developing nations, namely the Netherlands and Saudi Arabia. The IMF projects Indonesia's nominal GDP to reach US$2.25 trillion by 2031.
Similarly, Indonesia's purchasing power parity (PPP), which adjusts for local prices to show what money actually buys in Indonesia, provides a positive point of view as it sits in 7th place globally at US$5.36 trillion, ahead of Brazil, France and the United Kingdom. This places Indonesia above several G7 economies, long seen as the world's economic heavyweights, and makes it the only Southeast Asian country in the global top ten, alongside China, India and Japan. For investors, this means that costs and customers' spending power go further than the nominal figure suggests.
Furthermore, Indonesia is currently the only Southeast Asian G20 member, which means a seat where global economic policy is shaped. Alongside steady growth of 5.11% in 2025 and 5.61% year on year in the first quarter of 2026, this provides an investment environment that makes for more predictable planning. Although the rupiah's weakness against the dollar weighs on the nominal figure, the PPP measure looks past exchange rates and shows the underlying economy continuing to grow. A large economy that keeps growing steadily: this is what investing in Indonesia offers.
