Following the public hearing commenced by the Bank of Thailand (BoT) on August 5, a prominent risk management regulation was proposed. Reportedly, a specific target rule will take effect in October.
The consensus from the hearing points to a central bank mandate requiring financial institutions to scruntinise prospective customers who intend to buy high-value property worth at least 5 million Thai baht (115,000 US dollar) with cash. In accordance, buyers withdrawing or depositing 5 million Thai baht or more in physical cash must provide a formal declaration proving the rationale, necessity and source of funds.
Should a customer’s stated reason prove inconsistent, or if they fail to provide adequate documentation, banks are required to block the transaction and report it directly to the Anti-Money Laundering Office (AMLO).
Such measures are highly driven by persistent Thai concerns regarding illicit business operations within the territory. More broadly, this policy is in perfect alignment with the overarching Q4 2026 framework targeting the shadow economy, which also imposes stricter controls on bulk currency exchanges, bullion trading and suspicious stablecoin (USDT) flows.
In tandem with this context, the BoT, alongside the Thailand Banking Sector Computer Emergency Response Team (TB-CERT), held the 2026 Cybersecurity Annual Conference, titled “Responsible Innovation: Quantifying Cyber Risk for Business Trust”, on August 7. The BoT’s assistant governor Daranee Saeju acknowledged that “cybersecurity is not simply an IT issue,” rather “a fundamental to preserving trust in the financial system”.
She further explained that the central bank is working to broaden preventive measures to shield financial infrastructure from being exploited by illicit activities. This endeavour, she explained, is highly focused on increasing sophistication by utilising artificial intelligence (AI).
What does this mean for businesses?
For legitimate enterprises, this shift simply means adapting to tighter compliance protocols during major asset acquisitions. While transparent operations will face minimal disruption, businesses must prepare for extended bank processing timelines and stricter financial reporting. Ultimately, the framework might safeguard the market by weeding out illicit capital, although it remains inherently difficult to dismantle the transnational organised crime (TOC) networks within a Southeast Asia region that has been notoriously labelled as the “ground zero” for illicit business and scam syndicates.
