Finansia Syrus Securities Public Company Limited (FSS) is a Thai securities operating company and SET member 24. Its main retail distinction is between prefunded cash-balance trading, a cash account settled through ATS and a financed credit-balance account. The Thai SEC’s June 2026 KYC/CDD complaint is material: the current enforcement register still describes an inquiry, rather than a completed court case.[9][1][11][12]

SET’s SIPF scheme compensates eligible missing-client-asset losses only under its specified insolvency or unfulfilled-award conditions, up to THB1m per investor per participating broker. It does not insure trading losses. Confirm FSS’s current participation and the account’s eligibility before relying on that limit.[13]
