The Bank of Thailand (BOT) has officially implemented a new
regulatory framework supervising systemically important retail
payment systems (SIRPS), effective February 21, 2026, with
PromptPay being the first payment system designated as a SIRPS.
Under this new set of regulations, the BOT may designate payment
systems under the Payment Systems Act B.E. 2560 (2017) as SIRPSs
based on quantitative and qualitative assessments. Once a system is
designated as a SIRPS, the operator becomes subject to expanded
supervisory obligations beyond the general requirements of the
Payment Systems Act.
Enhanced Supervisory Requirements
SIRPS operators must comply with a heightened supervisory regime
across three key areas, outlined below.
