Wealth data as of 5 October 2026 (Forbes Real-Time). Country data per the IMF April 2026 projection.

Low Tuck Kwong is listed as the richest person in Indonesia, with a fortune of about US$16.5 billion, or Rp295.4 trillion, according to Forbes Real-Time Billionaires as of 5 October 2026. Behind him are Robert Budi Hartono (US$15.2 billion) and Prajogo Pangestu (US$15.0 billion).

Meanwhile, Monaco is the richest country in the world by GDP per capita at US$288,002 per resident, according to the IMF's April 2026 projection.

One thing to note up front: wealth rankings change every day because they are calculated from the value of shares in the companies people own. The figures in this article are a snapshot on the date shown, not permanent numbers.

Key Points

• Low Tuck Kwong is listed as the richest person in Indonesia at US$16.5 billion, from coal and energy.
• The top three are close together, only about US$1.5 billion apart, so the order can change within weeks.
• Data center businesses account for two of the ten names, Otto Toto Sugiri and Marina Budiman.
• Monaco is the richest country by GDP per capita, but this measure does not reflect the wealth of each resident.
• Nine of the ten richest countries have small populations. That is not a coincidence, and the final section explains why.

10 Richest People in Indonesia

Forbes Real-Time Billionaires data as of 5 October 2026.

Rupiah figures use an exchange rate of about Rp17,900 per US dollar and are rounded, so they may differ slightly from figures in other media.

What stands out in this list

The top three are only US$1.5 billion apart. Low Tuck Kwong US$16.5 billion, Robert Budi Hartono US$15.2 billion, Prajogo Pangestu US$15.0 billion. At a scale of billions of dollars, a gap of about 9% can reverse within weeks as share prices move. For comparison, in the 17 July 2026 data the gap across the top three was only US$800 million. That is why the top of this list is unstable, and who gets called number one depends on the date the data was taken.

The middle and bottom of the list have shifted too. Compared with the 17 July 2026 data, Tahir and family moved up to 5th and passed Sri Prakash Lohia, while Theodore Rachmat moved up to 9th and passed Lim Hariyanto Wijaya Sarwono.

The sector mix shows a shift. The biggest sources of wealth are still concentrated in natural resources: coal, petrochemicals, palm oil, and nickel. But two of the ten come from data center businesses, a sector that would not have made this list ten years ago.

This wealth is not cash. Almost all of it is the value of shares in companies they own. That means the figures rise and fall with the stock market and cannot be cashed out all at once without pushing down the price of their own shares.

Singapore is the only Southeast Asian country on this list. The IMF has scheduled the October 2026 edition for release on 13 October 2026, so the figures and order in this table may change after that.

Why the list is full of small countries

There is a clear pattern: nine of the ten countries on this list have small populations. Monaco has about 39 thousand people, Liechtenstein about 40 thousand, and Bermuda and the Cayman Islands each fewer than 100 thousand.

This follows directly from how GDP per capita is calculated: total economic output divided by population. A small denominator produces a large number.

Some countries on this list also have special features that lift their figures:

• Financial centers with large economic activity relative to their population. Luxembourg, Bermuda, and the Cayman Islands fall into this category.
• Headquarters of multinational companies. Ireland is the most frequently discussed example, because many global companies book revenue there for tax reasons. Its GDP grows without a matching amount of production inside the country.
• Abundant natural resources with a small population. Norway, with its oil and gas.

The United States, the largest economy in the world by total GDP, does not make the top ten on a per capita basis because its population is more than 340 million.

GDP per Capita Is Not the Wealth of Each Resident

This is the part that matters most, and the one most often misread.

GDP per capita is the average economic output per resident, not the income or wealth that each person actually holds.

It has three limitations:

• It does not account for inequality. A country with GDP per capita of US$100,000 can have most of its residents earning far less than that, if output is concentrated in a small segment.
• It does not account for cost of living. An income of US$100,000 in a country with very high property prices does not necessarily give a better standard of living than a lower income in a country with a cheap cost of living.
• It measures output, not ownership. If that output is produced by foreign companies whose profits are sent abroad, it still counts in GDP even though local residents do not enjoy it.

For a picture closer to residents' real conditions, more relevant measures are income per capita and GDP per capita at purchasing power parity, which adjust for price differences between countries.

The Pattern Across the Two Lists

Reading the two lists together, one thing stands out.

The biggest sources of wealth on the list of Indonesia's richest people are concentrated in productive assets, meaning ownership of companies. Not savings, not cash, and not property as the main part.

Meanwhile, the countries on the richest list mostly rely on a structural position, whether as a financial center, a place where multinational companies book their earnings, or an owner of natural resources with a small population.

The two lists share one thing: their value comes from owning something that produces, not from holding money. Cash loses purchasing power as inflation runs, while productive assets have a chance to grow faster than it.

We cover why paper money loses value over time in fiat money and what devaluation is. For an overview of the instruments in the digital asset category, see types of crypto.

To be clear: none of the names on the richest list built their wealth from digital assets, and this article does not suggest that is the way. The point is about productive assets versus cash, not about any particular asset class.

Conclusion

Low Tuck Kwong is listed as the richest person in Indonesia with a fortune of about US$16.5 billion, or Rp295.4 trillion, as of 5 October 2026, from coal and energy. The top three positions are only about US$1.5 billion apart, so the order can change quickly.

Monaco is the richest country in the world by GDP per capita at US$288,002, and Singapore is the only Southeast Asian country in the top ten.

The most important thing to remember from both lists: GDP per capita is not the wealth of each resident, and the wealth figures of the richest people are not cash but the value of shares that rise and fall every day.

Why do the rankings of Indonesia's richest people change so often?

Wealth is calculated from the value of shares in the companies people own, so it rises and falls with the stock market. The top three are only about US$1.5 billion apart, a gap that can reverse within weeks.

Is the wealth of the richest people held in cash?

No. Almost all of it is the value of shares in companies they own. The figures move with the market and cannot be cashed out all at once without pushing down the price of their own shares.

Which country is the richest in the world?

Monaco, with GDP per capita of US$288,002 per the IMF April 2026 projection. Next are Liechtenstein (US$226,809) and Luxembourg (US$158,733). The IMF has scheduled its October 2026 edition for 13 October 2026.

Why are the richest countries mostly small?

GDP per capita is total economic output divided by population, so a small population produces a large number. Nine of the ten richest countries have small populations, and several are financial centers.

Is GDP per capita the same as the wealth of each resident?

No. GDP per capita is the average economic output per resident. It does not account for inequality, cost of living, or who owns what is produced.

Which Southeast Asian country is in the top 10 richest countries?

Only Singapore, ranked 8th with GDP per capita of US$107,758 per the IMF April 2026 projection.

Is it better to hold cash or own productive assets?

Cash loses purchasing power as inflation runs, while productive assets have a chance to grow faster than it, but their value can also fall. This is not investment advice. Learn the basics in our fiat money article.
