Thailand’s foreign exchange reserves are a critical macroeconomic indicator, underpinning currency stability and external debt servicing capacity. The latest figure of 273.30 billion THB compares favorably with the 12-month average of 262.10 billion THB, signaling a strengthening external buffer.

Fiscal Policy & Government Budget

Fiscal discipline continues, with the government targeting a budget deficit of 3.50% of GDP in 2025. Foreign exchange reserves support sovereign creditworthiness, enabling sustainable borrowing costs. The government’s external debt stands at 18% of GDP, well within manageable limits.

External Shocks & Geopolitical Risks

Global trade tensions and regional geopolitical risks persist, but Thailand’s diversified export base and rising reserves provide resilience. The recent surge in reserves helps cushion against potential capital outflows triggered by external shocks.

Drivers this month

• Export earnings growth (3.10 billion THB)
• Foreign portfolio inflows (1.80 billion THB)
• Central bank currency interventions (1.00 billion THB)
• Reduced external debt repayments (-0.50 billion THB)

Immediate reaction: Thai government bond yields declined by 5 basis points, while the THB appreciated 0.30% against the USD. Market participants view the reserve build-up as a positive signal of external resilience.

Looking ahead, Thailand’s foreign exchange reserves face a mix of opportunities and risks. The base case scenario projects reserves stabilizing around 275 billion THB by year-end, supported by steady exports and moderate capital inflows.

Bullish scenario (30% probability)

• Global demand accelerates, boosting exports and tourism receipts.

Base scenario (50% probability)

• Exports and capital flows remain steady, maintaining reserves near current levels.

• Central bank may need to intervene more aggressively, tightening financial conditions.

Thailand’s foreign exchange reserves have strengthened notably in October 2025, reflecting a resilient external sector and prudent policy management. This improvement enhances the country’s ability to absorb shocks and supports a stable macroeconomic environment. However, vigilance is warranted given ongoing global uncertainties and regional risks.

Maintaining reserve growth while balancing monetary and fiscal policies will be key to sustaining investor confidence and economic stability. The Bank of Thailand’s measured approach and the government’s fiscal discipline provide a solid foundation for navigating the months ahead.
