Key operational functions
Open-market operations (OMO)
Liquidity management via bond repo
BoT conducts daily open-market operations primarily through bilateral repurchase agreements using Thai government bonds and BoT bonds as collateral. OMO is the primary tool for managing overnight interbank liquidity and keeping the actual interbank rate close to the 2.5% policy rate (as of 2024).
Government bond auction management
Primary-market issuance coordination
BoT acts as the issuance agent for Thai government bonds on behalf of the Public Debt Management Office (PDMO). Conducts competitive-bid auctions for Treasury bonds (2-50-year maturity) and Treasury bills (28/91/182-day). Primary dealers are required to bid at each auction.
FX bond cross-flow monitoring
Capital-flow surveillance
BoT's bond-market operations function monitors foreign-investor flows in the Thai government bond market. Non-resident holdings of Thai government bonds are approximately 10-15% of outstanding, down from a 2012-2013 peak of 20%. FX intervention is available when flows create excessive baht volatility.

Policy rate trajectory
MPC cut timing and bond-yield impact
If Thailand's MPC cuts the policy rate from 2.5% in 2025 (market pricing as of early 2025), Thai government bond yields would decline, generating capital gains for existing holders and reducing government borrowing costs. Rate-cut timing is a key driver of foreign-investor positioning in Thai bonds.
Government deficit financing
Fiscal expansion and bond supply
Thailand's fiscal deficit (approximately 3-4% of GDP in FY2024-2025) requires significant new government bond issuance. High bond supply relative to demand could steepen the Thai yield curve at longer maturities, requiring BoT OMO intervention to maintain orderly market conditions.
USD strengthening
Capital-outflow and baht-bond impact
A strong USD environment historically triggers capital outflows from emerging-market bonds including Thai government bonds. Non-resident sell-offs can push Thai long-bond yields up 20-50 basis points, requiring BoT to balance currency-stability goals with bond-market stability.
