Thai Baht Surges Past 31 per Dollar as Bank of Thailand Tightens Scrutiny on Gold-Linked FX Trades
Bangkok accelerates regulatory actions to temper rapid baht appreciation amid gold trading flows and dollar weakness
The Thai baht strengthened sharply against the US dollar in late 2025, breaking past 31 baht to the dollar and prompting authorities to take measures to curb the rapid rise as policymakers weigh implications for exports and tourism.
Currency data show the baht reached levels above 31.10 and 31.15 per US dollar in recent trading, its strongest in more than four years, propelled by record-high global gold prices and related trading flows that have amplified foreign exchange market movements.
Analysts have observed that these gains reflect heightened volatility rather than fundamental improvements in Thailand’s economy, with the currency emerging as one of the best performers in the region in recent weeks.
The Bank of Thailand (BoT) has responded by tightening its oversight of foreign exchange transactions, particularly those linked to gold trading, which central bank officials say have accounted for a significant share of dollar sales and baht purchases.
BoT Governor Vitai Ratanakorn noted that such flows, at times representing as much as twenty per cent of total FX market activity, have added upward pressure on the baht and triggered closer scrutiny of dollar-selling documentation by commercial banks.
The central bank is also seeking approval from the Ministry of Finance to obtain detailed FX transaction data from major gold dealers to bolster monitoring and risk assessment.
In parallel, the Ministry of Finance and BoT are exploring broader measures to manage the surge, including potential reporting requirements for online gold trading platforms and consideration of tax or transaction-limit frameworks for gold dealers active through digital apps, aiming to address abnormal inflows without constraining ordinary retail activity.
Officials emphasise that these steps are designed to enhance transparency and financial stability while avoiding undue impact on everyday consumers and small-scale traders.
Policymakers have flagged concerns that a persistently strong baht could weigh on key economic drivers such as Thailand’s export sector and tourism, as a robust currency can make Thai goods and services less competitively priced abroad.
The central bank’s actions form part of a broader effort to ensure that exchange rate movements remain aligned with underlying economic fundamentals, particularly as global dollar weakness and seasonal capital flows continue to influence markets.
