Thailand will introduce stricter rules on large cash transactions within the next two weeks in a decisive effort to curb grey capital and money laundering.

Under the new measures, any cash deposit or withdrawal exceeding five million baht will require banks to conduct enhanced due diligence.

Financial institutions will be required to obtain clear explanations regarding both the source and the intended purpose of the funds before processing such transactions.

Governor Witteirata Nakan stated that the central bank is moving beyond the boundaries of traditional monetary policy to confront deeper structural risks within the economy.

A central priority is addressing illicit financial flows that undermine financial stability and public trust.

Oversight of transfer systems and digital payment channels has already been strengthened, reflecting a broader regulatory shift toward tighter supervision of the financial ecosystem.

Additional stringent regulations for electronic money operators are also being prepared.

The new criteria are expected to be formally announced within the next two weeks.

The measures mark a significant step in reinforcing the integrity of Thailand’s financial system.
