Thailand's Currency Remains Strong With $300 Billion Reserve Buffer

The Bank of Thailand says the country's external stability remains solid, with limited risk of severe capital outflows. The central bank revealed that capital inflows into Thai assets have totaled roughly 50 billion baht since the start of the year. On September 18, Surachai Thanbunyong, senior director of the monetary policy department at the Bank of Thailand, stated that the baht's movement is primarily driven by dollar fluctuations, which depend on global economic conditions, major central banks' policies, and geopolitical factors.

The interest rate differential between Thailand and the United States is already priced into the market, as reflected in the baht's stable movement in recent periods. Regarding Japan's recent move to raise rates to 1.25%—which is not significantly different from Thailand's—the Bank of Japan's non-unanimous 7-2 decision has prompted markets to reduce expectations for further hikes.

The Bank of Thailand assesses that its current policy rate is appropriate for Thailand's context, with future moves dependent on the outlook. Given that the Thai economy is recovering below potential and inflation is rising from supply-side factors, monetary policy can remain accommodative while supporting coordinated multi-sector policies to address economic challenges.

Thailand's external stability remains strong with substantial buffers. Net foreign reserves exceed $300 billion, well above international standards and covering short-term foreign debt 2.8 times over. This means the risk of severe capital outflows is limited. Although some capital has moved out since the Middle East conflict began, outflows remain relatively low compared to other regional countries, so the Bank of Thailand is not concerned about capital flight.

Since the start of 2025, portfolio flows have remained positive, with roughly 50 billion baht in net inflows into Thai assets, driven primarily by stock market investment and bond purchases.
