Thai banks face 200% fraud surge as cybercrime outpaces ASEAN peers
Fraud losses in Thai banks have surged over the past five years, rising by more than 200%. A new report reveals that cybercrime and internal misuse now cost financial institutions billions annually. Many banks admit their current defences are falling short.
Between 2021 and 2025, annual fraud losses in Thailand jumped from 1.2 billion baht to 3.8 billion baht. This increase outpaced other ASEAN nations, with Indonesia seeing a 150% rise, the Philippines 180%, and Malaysia 120%. Cyber fraud and insider abuse were the main drivers behind Thailand's sharp climb, according to the ASEAN Banking Fraud Report 2025.
A recent survey found that 87% of Thai banking leaders reported growing fraud losses. Four in five institutions lose over 155 million baht ($5 million) yearly, while 55% exceed 310 million baht ($10 million). Despite the rising costs, only 23% of banks can fully investigate fraud cases within a day.
Nearly all respondents (92%) flagged real-time payments as a significant risk. The speed of instant transactions leaves little time to spot suspicious activity. At the same time, 87% of banks struggle to detect money mule accounts, particularly when they span multiple institutions.
Current fraud controls are seen as weak, with 39% of leaders rating them five out of ten or lower. In response, 85% of banks are now exploring new detection technologies. Behavioural-based tools are gaining traction, with 76% either using or testing them.
Reputational harm also weighs heavily on institutions. Three-quarters of respondents view damage to public trust as a bigger threat than financial losses alone.
Thai banks face mounting pressure as fraud losses climb and detection gaps persist. With real-time payments expanding, institutions are racing to upgrade their defences. The shift toward behavioural-based tools signals a push for faster, more effective solutions.
