The BOT is expanding auction sizes for short-term bills and THOR-linked floating-rate bonds in 2026, with a structured schedule to align with liquidity needs and public debt supply
The Bank of Thailand (BOT) issues BOT bonds as one of the monetary policy instruments used to manage money market liquidity, while fostering the development of a liquid debt securities market in Thailand. The annual BOT bond issuance programme is regularly communicated to the market at the start of each year to facilitate smooth and efficient liquidity management among market participants.
For 2026, the bond issuance programme considers the projected liquidity condition in the market, the expected demand for public debt securities and the overall public sector bond supply. To this end, the BOT and the Public Debt Management Office (PDMO) have been collaborating closely on bond issuance in order to maintain an appropriate level of overall public sector bond supply throughout the year.
For the BOT Bond Issuance Programme for 2026, the auction sizes for 3-month and 1-year bills are raised to 35,000 – 75,000 and 25,000 – 65,000 million baht per auctionrespectively. Additionally, the maximum auction size for the 6-month THOR-linked floating-rate bonds is raised to 40,000 million baht per auction.These adjustments aim to align with market conditions.
