Thailand is taking a bold new step to stem the tide of online financial scams, introducing strict daily transfer caps for mobile and internet banking customers. Announced on August 19, 2025, by the Bank of Thailand (BOT), the move is a direct response to a surge in digital fraud that has cost consumers and the financial system billions. The new rules, which will affect millions of bank users across the country, are already making waves among customers, banks, and regulators alike.
According to the Associated Press, the BOT now requires banks to set a daily limit of 50,000 baht (about $1,537) on many online transfers. The regulation is especially targeted at protecting the most vulnerable—children and the elderly—who have been disproportionately affected by scams in recent years. Daranee Saeju, assistant governor for Payment Systems Policy and Financial Consumer Protection at the BOT, explained that the goal is to "prevent criminals from receiving and transferring a large amount of money at one time, and enable timely freezing of illicit funds in order to increase the chances that victims will be able to recover at least some of their money."
The new transfer caps are part of a three-tiered system. Customers will be assigned daily limits of under 50,000 baht ($1,537), under 200,000 baht ($6,147), or above 200,000 baht, depending on their risk profile as determined by banks through know-your-customer (KYC) processes. This means that while the strictest cap will apply to those deemed most at risk—such as new users, children under 15, and adults over 65—customers with a proven track record of responsible transactions may continue to enjoy higher transfer thresholds.
The regulation is being rolled out in phases. For new mobile and internet banking customers, the rules take effect by the end of August 2025. Existing users will have until December 31, 2025, to comply. This staged approach is designed to give banks time to adjust their systems and inform customers while ensuring that the most pressing risks are addressed quickly.
The urgency behind these measures is clear. As reported by the Bangkok Post and corroborated by multiple outlets, June 2025 alone saw 24,500 scam cases related to money transfers, resulting in losses totaling 2.8 billion baht ($86.1 million). The average loss per case was a staggering 114,000 baht ($3,504), and the largest single fraudulent transfer reached 4.9 million baht ($150,591). Even more alarming is the speed with which scammers operate: on average, they siphoned off half of the stolen funds within just three minutes, while it typically took victims between 19 and 25 hours to report the crime.
The scope of the problem is vast. In the first half of 2025, children under 15 were involved in 78,468 financial scam cases, while victims over 65 accounted for 416,453 cases, according to data cited by the BOT and reported by AP. These numbers underscore why the new rules are particularly focused on vulnerable groups. Banks are now required to monitor these accounts more closely, impose tighter transfer limits, and conduct extra verification checks to reduce risk.
The BOT's approach is not one-size-fits-all. Customers who need different transfer limits for legitimate reasons—such as business payments or family support—can request changes through their bank's mobile app, by phone, or in person at a branch. This flexibility aims to balance security with convenience, a crucial consideration as Thailand continues its rapid shift toward digital banking.
That shift has been dramatic. According to figures cited by the Bangkok Post and other outlets, Thailand had just 18 million online banking users in 2009. By 2020, that number had soared to over 50 million, and as of August 2025, there are about 12 million mobile banking users alone. This digital transformation has brought many benefits, but it has also created new opportunities for scammers, whose tactics range from phishing text messages and fake loan apps to sophisticated voice cloning schemes.
The BOT has been proactive in responding to these evolving threats. Previous safeguards included capping mobile banking transfers at 50,000 baht per transaction (with facial recognition required) and 200,000 baht per day in total. But as scam methods have grown more sophisticated, regulators have recognized the need for even stricter controls. As Daranee Saeju put it, "Capping transfers will slow down the thieves, making it easier for banks to freeze suspicious activity. This could help return lost money to some victims."
Thailand's crackdown is also part of a broader global trend. Regulators worldwide are putting pressure on banks to take a more active role in protecting customers from online fraud. The scale of the problem in Southeast Asia is particularly acute, with criminal networks exploiting the region's rapid digitalization and sometimes lax enforcement. In Thailand, the BOT has stepped up cooperation with local banks and law enforcement, and by July 2025, banks had already closed more than 3 million accounts linked to fraud, including 177,000 so-called "mule accounts" used to move illicit funds.
Not everyone is thrilled about the new restrictions. Some customers worry that the caps will make it harder to conduct legitimate business or personal transactions, especially for those who regularly need to transfer large sums. However, the BOT has emphasized that the system is designed to be adaptable, with higher limits available for those who demonstrate a history of responsible banking.
As the banking sector adapts to these new rules, the BOT is keeping a close watch. The central bank has promised to review and update the regulations as scam tactics evolve, ensuring that Thailand's financial system remains both safe and user-friendly. "The main aim is to give Thai banking customers a safer environment without losing the ease of digital services," Daranee Saeju told reporters, according to AP.
For now, the message from the Bank of Thailand is clear: the fight against online financial fraud is entering a new phase, one that puts customer protection front and center. With digital scams showing no sign of slowing down, the stakes for banks, regulators, and ordinary Thais have never been higher.
Thailand’s decisive action to cap online transfers is a sign of the times—a necessary adjustment in a world where convenience and risk often go hand in hand, and where vigilance is the new normal for anyone moving money online.
