Banks in Thailand are increasing scrutiny of digital financial transactions as part of ongoing efforts to combat fraud and the use of so-called “mule accounts.” These accounts are often used by criminals to move funds linked to scams or illegal activities. Following stricter controls on traditional bank accounts, financial institutions are now focusing more closely on digital banking channels. Under guidance from the Bank of Thailand, banks are strengthening monitoring systems and introducing measures designed to detect suspicious activity earlier.

As part of this approach, banks are aligning transaction limits with customer risk profiles under a tiered framework. Customers are categorized into three levels—S (small), M (medium), and L (large)—based on financial behavior and account activity. Mobile banking transfer limits typically correspond with these categories, with daily ceilings of under 50,000 baht, 50,000 to 200,000 baht, and above 200,000 baht respectively. Some banks are also reviewing policies around digital savings accounts and considering combined transfer limits across multiple mobile banking platforms in order to close potential loopholes.

For businesses operating in Thailand, these changes may result in stricter identity verification, closer monitoring of transactions, and limits on daily transfers through mobile banking platforms. Companies that rely on digital payments, supplier transfers, or frequent online transactions should review their banking arrangements to ensure they align with current compliance requirements and do not disrupt operational cash flow.

The tightening of these measures is already having an effect, with industry estimates suggesting that fraud-related losses in the banking system have declined significantly over the past year. For business owners, the key takeaway is clear: maintaining transparent financial practices and well-managed corporate banking structures is becoming increasingly important in Thailand’s evolving regulatory environment.

New Scrutiny for Foreign-Owned Businesses in Thailand

Thailand is stepping up efforts to prevent the use of Thai “nominee” shareholders in companies controlled by foreign investors. The Department of Business Development (DBD) under the Ministry of Commerce is preparing new rules aimed at closing loopholes that allow foreigners to operate restricted businesses by placing shares in the names of Thai individuals who are not the true owners.

According to government data, Thailand currently has more than 780,000 registered companies, and about 118,000 include some level of foreign shareholding below 50 percent. Authorities believe that a large portion of these may involve nominee arrangements. Earlier measures introduced at the start of 2026 already require Thai shareholders in certain foreign-linked companies to provide bank statements proving they have the financial means to purchase their shares. Officials say those rules have already reduced questionable registrations but attempts to bypass the system continue.

For business owners, the main change is that company registrations and amendments involving foreign participation will face closer scrutiny. Authorities are expected to require additional documentation when foreigners are added as partners, directors, or authorized signatories. Regulators are also increasingly verifying company addresses—particularly when multiple businesses are registered at the same location—and checking shareholder information against government databases used for financial crime monitoring.

Investigations in sectors such as tourism, property development, and export-related businesses show that enforcement is becoming more active. Under Thailand’s Foreign Business Act, both Thai nominees and the foreign individuals behind them can face fines of up to 1 million baht and possible imprisonment if authorities determine the structure was designed to bypass foreign ownership restrictions.
