The Bank of Thailand has introduced new mandatory reporting requirements for large cash inflows from non-residents as part of a broader strategy to strengthen financial oversight and manage the recent rapid appreciation of the Thai baht.

Under the updated regulations, Thai banks are required to submit detailed reports to authorities on any incoming capital transfers from non-residents that exceed two hundred thousand US dollars, including the purpose of the transfer and supporting documentation.

The central bank governor, Vitai Ratanakorn, said the reporting requirement marks the first time such inflows will undergo review for both their intent and documentation, aiming to give policymakers a clearer picture of cross-border financial flows.

In addition to cash transfers, banks will also be required to report gold trading transactions conducted via digital platforms on both a per-day and per-transaction basis to ensure comprehensive monitoring of foreign exchange activity driving currency movements.

Officials have emphasised that the stricter reporting framework is intended to enhance the Bank of Thailand’s ability to monitor and respond to movements in the baht without directly targeting a specific exchange rate, consistent with international agreements that prevent direct manipulation of currency values.

The baht has strengthened significantly against the US dollar in recent months, outpacing several regional peers, prompting regulators to seek better tools to understand and manage volatile inflows linked to capital flows and digital asset trading.

The new reporting measures, which took effect at the end of December 2025, reflect broader efforts by Thai authorities to bolster financial system resilience and transparency.

By requiring enhanced disclosure of large foreign cash inflows and related transactions, policymakers aim to improve oversight of international capital movements and contribute to financial market stability amid evolving global conditions.
