Foreign Exchange Market

Thailand has operated under a managed float exchange rate regime since July 2, 1997. Under this regime, the Thai baht is determined by market forces and reflects prevailing economic conditions. The Bank of Thailand (BOT) does not target a specific exchange rate or peg the Thai baht to any foreign currency. However, the BOT may intervene in the foreign exchange market when the baht experiences excessive volatility that could impede the adjustment of the real economic sector.

The Thai baht generally moves in line with major global currencies, including the US dollar, the euro, the British pound, and the Japanese yen. This reflects the significant influence of external factors on exchange rate movements, such as monetary policy decisions by major central banks, differences in economic outlooks across countries, and shifts in global investor sentiment and risk appetite. Domestic factors, including labor market conditions, the recovery of the tourism sector, current account balances, and Thailand's strong external stability, also contribute to maintaining confidence in the Thai baht.

As Thailand’s economy has become more complex and more deeply integrated with the global economy, exchange rate movements have become increasingly volatile. If exchange rate volatility becomes excessive and could adversely impact the adjustment of the real economy, the BOT may intervene in the foreign exchange market as deemed necessary. In assessing market conditions, the BOT considers not only the USD/THB exchange rate but also a range of indicators, including the Nominal Effective Exchange Rate (NEER), which measures the value of the Thai baht against the currencies of Thailand’s major trading partners and competitors. In this regard, foreign exchange intervention remain consistent with Thailand’s economic fundamentals.

To manage exchange rate volatility, the BOT assesses appropriate policy tools based on prevailing market conditions.

BOT may conduct foreign exchange operations to mitigate excessive short-term volatility, which may result in changes in the level of international reserves.

To moderate rapid appreciation of the Thai baht, the BOT may purchase foreign currency and sell Thai baht, thereby increasing international reserves. Conversely, to limit sharp depreciation pressures, the BOT may sell foreign currency and purchase Thai baht, resulting in a reduction in international reserves.

In addition, if signs of speculative activity emerge in the foreign exchange market, the BOT may implement supplementary measures, including measures to prevent thai baht Speculation, and adjust their intensity as appropriate in response to market conditions.

In this regard, changes in the value of international reserves over time are not solely driven by foreign exchange operations. International reserves are also affected by investment returns and valuation changes when reserve assets are expressed in US dollar terms. In practice, valuation effects account for the majority of fluctuations in international reserves.
