The Stock Exchange of Thailand (SET) confirmed that its securities trading and payment systems continue to operate normally following a Microsoft 365 outage. Thirapan Sarapak, SET's Deputy Managing Director and Head of Information Technology, stated that SET closely monitored the situation and verified that all primary systems — including trading, payment, depository, and listed company disclosure systems — remain fully operational and unaffected. The issue impacted only email reception, which is isolated from the exchange's trading and core operational systems. SET maintains alternative communication channels to ensure continuity and regularly assesses risks and contingency measures to keep trading running smoothly.
