BOT projects 2027 Thai inflation to dip briefly into negative territory

The Bank of Thailand (BOT) has announced that Thai headline inflation is projected to average 2.1% in 2026 before dipping temporarily into negative territory in 2027, driven primarily by high base effects from 2026 and falling global crude oil prices.

Inflation Outlook and Energy Dynamics

Don Nakornthab, Senior Director of the Monetary Policy Department at the Bank of Thailand, stated that short-term inflation is expected to remain stable at an elevated level through the first quarter of 2027 before gradually tapering off.

Global crude oil prices are estimated at 93 US dollars per barrel for 2026, falling to 76 US dollars per barrel in 2027.

While headline inflation may experience a temporary sub-zero reading next year, officials emphasized that this does not signify structural deflation.

Core inflation remains stable and is not declining as sharply as headline inflation, which is heavily influenced by energy components. However, energy prices continue to pose a significant risk. The state continues to manage retail domestic prices through the Oil Fuel Fund, but the fund currently carries a deficit of approximately 108,000 million baht, severely restricting its capacity to cushion future external shocks or sudden oil price spikes.

Monetary Policy and Policy Rate Stance

The Monetary Policy Committee (MPC) voted unanimously to maintain the policy rate at 1.00% per annum, viewing it as appropriate to support an uneven economic recovery. The central bank noted that if inflation remains low and stable, monetary policy can place greater weight on supporting economic growth.

At the same time, the BOT cautioned that maintaining a low interest rate for an extended period could accumulate long-term financial stability risks across three key areas:

Financial sector vulnerabilities arising from over-indebtedness and the underpricing of risk.  

External stability risks driven by capital movements and foreign exchange volatility.  

Resource misallocation, which may allow uncompetitive businesses to persist artificially due to low borrowing costs.  

The central bank indicated that if the economic recovery becomes more pronounced, domestic demand strengthens, and price pass-through increases, the BOT stands ready to gradually roll back excessive monetary accommodation.

Economic Growth and Structural Challenges

The BOT revised its economic growth forecast for Thailand to 2.4% for 2026, with growth expected to register at 2.1% in 2027. Although figures show marginal improvement, overall economic expansion remains below potential.

Private investment is clearly on an upward trend driven by artificial intelligence-related business investments, but the labor market remains vulnerable amid mounting economic uncertainties.

The recovery continues to display a K-shaped profile, lacking uniform momentum across sectors. Sustainable and broad-based recovery requires improvements across business activity, employment opportunities, and household incomes alike.

AI Integration and Key Downside Risks

Pranee Sutthasri, Senior Director of the Macroeconomic Policy Department, noted that artificial intelligence is actively transforming economic structures, affecting productivity, manufacturing output, employment, and business models. A critical policy challenge is ensuring that productivity gains are distributed broadly across businesses and workers rather than concentrated in specific segments, which could otherwise widen income disparities.

Key downside risks requiring continuous monitoring include geopolitical conflicts affecting global trade and energy markets, alongside tighter financial conditions that exert pressure on households and small-to-medium enterprises.
