Thailand’s New Economy to Become SET’s Next Big Catalyst

Thailand has a capital-market problem that is becoming harder to ignore: the economy is changing, but the stock market still looks remarkably similar to the one built decades ago.

Energy and utilities have historically been the heavyweight of the Stock Exchange of Thailand, consistently accounting for more than 20% of the SET Index’s market capitalization. Banks, property and other traditional industries have also played an outsized role.

There is nothing inherently wrong with having large energy or banking companies on the exchange. The problem is what their dominance says about the structure of Thailand’s capital market.

While the economy is trying to move into its next chapter, the stock market remains heavily tied to its last one.

That is why the government’s attempt to connect Board of Investment-promoted companies with the Thai capital market deserves more attention than simply another initiative to increase IPOs.

Thailand is already seeing a substantial shift in where investment is going. In the first six months of 2026, applications for investment promotion reached 1,300 projects worth 1.47 trillion baht, up 37% from the same period a year earlier. Digital industries alone accounted for 1.12 trillion baht, followed by electronics and electrical appliances at 120.2 billion baht. Investment is also flowing into electric vehicles, logistics, automation and robotics.

This is the kind of investment Thailand has spent years trying to attract.

But attracting factories, data centers and advanced manufacturing facilities is only half the equation. Thailand also needs a financial ecosystem capable of funding these businesses as they grow.

That is where the BOI-to-IPO initiative could become strategically important.

The Securities and Exchange Commission and SET have been working to create a special pathway for New Economy companies, including businesses promoted by the BOI and the Eastern Economic Corridor Office. The objective is not simply to add more names to the exchange, but to make the Thai capital market a more accessible source of funding for companies operating in industries that are expected to drive future growth.

The timing is particularly important.

Thailand is competing for investment at a time when companies are reassessing global supply chains amid geopolitical tensions and economic uncertainty. Capital is looking for locations that offer infrastructure, supply-chain connectivity and policy support. Thailand has an opportunity to position itself not merely as a manufacturing base, but as a place where companies can invest, expand and eventually raise capital.

That requires the capital market to become part of the investment strategy rather than an afterthought.

The SEC’s move to streamline the IPO approval process is therefore significant. It aims to reduce the average consideration period from 147 days to 60–100 days. Crucially, the objective is not to remove regulatory requirements, but to make the process faster and more efficient while retaining investor protection.

The message from policymakers should also be clear: Thailand does not need IPOs for the sake of IPOs.

It needs quality companies.

A rapid increase in listings could make the statistics look impressive without fundamentally changing the market. The real test is whether new-economy companies can use the Thai capital market to finance expansion, develop their supply chains and create value that remains in Thailand.

The potential benefits extend well beyond the exchange.

A company that raises capital locally has more resources to reinvest. New-economy businesses create new investment opportunities for the market. Their expansion can generate jobs and demand for domestic suppliers, while helping diversify the economic base.

The BOI estimates that projects approved for investment promotion in the first half of 2026 could create more than 82,000 jobs, use more than 386 billion baht of domestic raw materials annually and generate over 1.2 trillion baht in annual exports.

That is the bigger opportunity.

Thailand’s capital market should not abandon the industries that built it. Energy companies, banks and traditional businesses will remain important to the economy.

But a stock market that continues to reflect mainly yesterday’s economy risks becoming less relevant to tomorrow’s investors.

The BOI-to-IPO strategy is ultimately an attempt to close that gap.

If Thailand can connect investment promotion with capital-market access, the country could create a cycle in which new investment produces new businesses, new businesses create new investment opportunities, and the capital market helps finance the next stage of growth.

The goal should not be a bigger stock market.

It should be a stock market that better represents the economy Thailand is becoming.
