Just 12 Thai Industry Codes Hold Half of Corporate Assets 2026
In short
Twelve. That is how many of Thailand's 997 five digit industry codes with asset data it takes to reach half of the country's corporate balance sheet. Those 12 codes are 1.2 percent of all coded industries. They hold 51.1 percent of the country's 102.6 trillion baht in reported assets as of 7 July 2026. One code alone holds 22.2 percent of the national total. Just 19 companies file under it. The other 985 codes split the remaining 48.9 percent among thousands of businesses.
How many industry codes hold half of Thailand's corporate assets?
Twelve. Out of the 997 five digit industry codes that reported total assets for statement year 2568, the most recent year with a full set of filings, just twelve carry half of everything on Thailand's corporate balance sheet. That works out to 1.2 percent of coded industries holding 51.1 percent of the country's corporate assets. Thailand's registered companies reported 102.6 trillion baht in total assets as of 7 July 2026. The remaining 985 codes split the leftover 48.9 percent among themselves. One single code holds 22.2 percent of the national total on its own. Just 19 companies file under that code. Concentration this steep does not happen by accident. A handful of codes inside financial and insurance, real estate, manufacturing, electricity and gas, and accommodation sit at the very top, and thousands of other codes across the rest of the economy trail far behind.

Each bar is one five digit code. The first two codes alone account for more than 30 percent of all reported corporate assets in Thailand.

Ranked by total reported assets, statement year 2568, as of 7 Jul 2026. Section letters are the fixed one letter TSIC groupings.
Why this matters beyond those twelve codes
Most of Thailand's registered corporate capital sits in very few places. A shock to a handful of financial, real estate or utility codes would move the whole corporate balance sheet far more than a shock spread evenly across manufacturing or retail. Asset based measures like collateral capacity and borrowing power cluster the same way. They do not spread out with company count. The 71,899 companies inside the top 12 codes hold just over half of national assets. Those same companies make up only 10.1 percent of the 712,785 companies with reported data that year. A policy aimed at broadening access to credit or investment has to reckon with a corporate asset base this lopsided, not one that is evenly spread across the register.
Definitions
- TSIC code
- Thailand's five digit Standard Industrial Classification code, the finest level of industry detail DBD publishes for a company's registered business activity.
- Section
- The single letter grouping of many TSIC codes into one of 21 broad industries, such as C for manufacturing or K for financial and insurance.
- Total assets
- The sum of assets reported on the balance sheet of every company that filed a financial statement for a given TSIC code and statement year.
- Statement year
- The fiscal year a company's filed financial statement covers, recorded by DBD in the Buddhist calendar. Statement year 2568 corresponds to 2025 in the Gregorian calendar.
- Concentration
- How unevenly a total is spread across its parts. High concentration means a small number of units hold most of the value.
Assumptions
- Only companies that filed a financial statement for statement year 2568 contribute to total assets, so unfiled or dormant companies are not counted.
- Statement year 2569 was excluded because filings were still incoming as of 7 July 2026, with only a few thousand companies represented so far.
- Individual five digit TSIC codes cannot be named because DBD's descriptive field for that level is not populated in this dataset, so codes are identified by number and section letter only.
Methodology
Total assets and company counts come from the DBD registry's five digit TSIC breakdown for statement year 2568, the most recent year with a full set of filings, as of 7 July 2026. Statement year 2569 was excluded because only a few thousand companies had filed by this date, far short of a complete year. Codes were ranked by total assets from largest to smallest, and the running sum was checked against the sector wide total to find the smallest number of codes whose combined assets pass half of the national figure. Section letters shown next to each code are the fixed one letter TSIC sections DBD assigns. The finer five digit industry name is not published in the underlying data, so codes are identified by number only.
How we verified this
- Summed total_assets across all 997 TSIC codes with data in statement year 2568: 102,628,594,300,162.72 baht, which rounds to 102.6 trillion, matching the reported grand total.
- Ranked all 997 codes by total_assets descending and computed a running sum. The sum crosses half of the grand total at the 12th code, 52,446,783,029,050.73 baht, which is 51.10 percent of 102,628,594,300,162.72. The 11th code alone only reaches 49.92 percent, confirming 12 is the minimum count needed.
- 12 divided by 997 recomputes to 1.20 percent, the share of codes figure used in the headline.
- Summed company_count for the top 12 codes: 71,899, divided by the year's 712,785 total companies with data, recomputes to 10.09 percent, rounded to 10.1 percent.
- The single largest code, 22,751,878,020,378 baht divided by 102,628,594,300,162.72, recomputes to 22.17 percent.
