**Thailand has officially entered a state of technical deflation, marked by ten 
straight months of declining inflation rates.**

### Key Takeaways on Thailand’s Technical Deflation

 * **Definition & Context**
    - Thailand has entered _technical deflation_, defined as a sustained decline
      in prices for more than six months.
    - Inflation has been negative for 10 consecutive months, averaging **-0.13% 
      in 2025**.
 * **Economic Risks**
    - Deflation often signals weak demand: households consume less, businesses cut
      investments, and margins shrink.
    - Thailand’s growth slowed to **2.4% in 2025**, raising concerns about a deflationary
      spiral similar to Japan’s post-1990 stagnation.
    - Deflation can cause consumers and businesses to delay spending and investment,
      worsening recessionary pressures.
 * **Nuances in Thailand’s Case**
    - Household consumption remains weak but still positive.
    - The **Bank of Thailand** emphasizes that _underlying inflation_ (excluding
      energy) is still positive, framing this as “negative inflation” rather than
      full deflation.
    - Authorities expect recovery through **tourism rebound** and **household consumption
      growth**.

The statistics of the kingdom have shown for 10 months inflation results lower than
the experts’ statistical forecasts (these being on average negative for the whole
of 2025 with -0.13% annual average) according to Thanavath Phonvichai (the associate
professor and president of the University of the Thai Chamber of Commerce and chairman
of the Economic and Trade Forecast Center) in technical deflation.

Although the growth forecasts for 2026 suggest a simultaneous recovery in inflation,
it appears to show no signs of slowing down, which could have adverse effects on
the Thai economy.

If Europe and the world are much more aware of the dangers of inflation, the opposite
phenomenon remains rare since Covid and the recent global geopolitical crises are
rather synonymous with rising raw material costs.

Price deflation is a general and long-lasting corollary, often indicative of a marked
weakening in demand and economic activity. It reflects a deep slowdown: households
consume less, businesses reduce their investments and margins contract.

The Thai case, however, appears more nuanced. The growth and consumption of households
in the kingdom are certainly at half-mast but appear positive. Experts define a «
technical deflation» as a lasting decrease in prices for more than 6 months due,
according to Phonvichai, to the general decrease in fuel costs and agricultural 
prices.

Government measures also pushed global prices down, the consumer price index (CPI)
dropped by -0.66% at the beginning of 2026 compared to the same month last year,
more than expected.

Nevertheless, Bank of Thailand reassures and talks more about negative inflation,
highlighting that the figures for underlying inflation (excluding energy costs) 
remain positive.  Under the vigilance of the kingdom’s economic institutions, the
financial system remains. More than a classic deflationary episode, Thailand would
go through a cyclical adjustment, prelude to an upturn due to the increase in household
consumption and the recovery of tourism, planned by those same authorities.

The possibility of a return to deflation cannot be ruled out, says Thanavath Phonvichai.
Indeed, the weak growth that the country is experiencing (2.4% in 2025) may, if 
monetary and budgetary policies to restart the kingdom’s growth can degenerate into
a deflationary spiral.

A scenario feared by the economic authorities of the country of smiles, given the
consequences it had on Japan after the crash of 1990. Deflation indeed pushes consumers
and all economic actors to wait: they postpone their investments in anticipation
of lower prices, demand collapses, companies suffer revenue losses, cut jobs creating
a loop in which the economy sinks into a deeper recession.

This scenario also concerns and worries the Chinese neighbor, which has been observing
a slowdown in its dynamic real estate sector and household consumption since 2023.
