# Bank of Thailand tightens checks on foreign-currency and gold inflows as Singapore prepares another tightening

Thailand is using paperwork rules to slow a gold-driven rise in the baht, while China's central bank says it will keep letting the market decide the yuan's exchange rate.

The Bank of Thailand (BOT) is [tightening checks on foreign-currency inflows and gold transactions](https://www.nationthailand.com/business/banking-finance/40072040), The Nation reports. The move adds to rules in force since December 29, 2025. Under those rules, banks must [verify the source and purpose of incoming foreign currency worth $200,000 or more](https://www.hlbthai.com/bank-of-thailand-bot-applies-stricter-document-checks-for-foreign-currency-inflows/), and must get proof of an overseas gold sale for every gold-related foreign-exchange transaction.

The rules target gold trading. Thai authorities say [daily gold trading values have reached roughly half of Thailand's gross domestic product](https://thailand.prd.go.th/en/content/category/detail/id/2541/iid/458538). Gold-linked deals at times account for up to 20% of foreign-exchange turnover, which creates large flows through the dollar that push the baht higher. The Finance Ministry and the BOT have also proposed taxing online gold trading in the same way as ordinary goods and limiting transaction volumes. Thai households and traders are using gold as a store of value on a large scale, and the state is responding by adding cost and paperwork to that trade.

Singapore faces the opposite problem. The Monetary Authority of Singapore (MAS) manages its currency instead of setting an interest rate, and it is [expected to tighten policy](https://www.investing.com/news/economy-news/singapore-poised-to-tighten-monetary-policy-amid-strong-growth-and-rising-inflation-risks-4940164) because growth is strong and inflation risks are rising. That means letting the Singapore dollar rise faster. The MAS has already [tightened twice this year](https://www.businesstoday.com.my/2026/07/28/policy-outlook-on-singapore-revised-after-recent-mas-tightening-forecast-for-another-round-in-october/), in April and July.

In Beijing, the People's Bank of China (PBOC) [said it remains committed](https://english.news.cn/20261009/febdca8836524c6fa8481a28aab2bf64/c.html) to letting the market play the decisive role in setting the yuan's exchange rate. State media publish this standard language whenever the central bank wants to discourage bets on a one-way move. The PBOC still sets a daily reference rate, and its statement leaves that power in place.

## What this means

The three central banks are managing the same high-dollar, high-oil environment with different tools. Singapore uses its exchange rate openly as an anti-inflation tool. Thailand adds friction at the bank counter so that gold trading does not push the baht higher. China restates that the market leads while keeping its daily reference rate. The Thai measures hurt foreigners who bring money into Thailand, gold dealers, and residents who hold gold and sell it abroad. Each large inflow now needs documents and can be delayed. Most market attention is on interest rates, but the new development is administrative control of capital and gold flows, which is harder to price and easier to tighten. The desk's read is that Thailand will add further limits on gold trading or volume caps within months if the baht keeps rising, because the BOT has already shown it prefers administrative measures to cutting rates. A clear fall in gold prices that slows Thai trading volumes on its own would make further measures unnecessary and prove this read wrong.

## What to watch

- Whether Thailand puts its proposed online gold tax and volume limits into law. This would turn guidance into binding capital-flow restrictions.
- The MAS policy statement this month. A third tightening would confirm that Singapore is using a stronger currency to fight imported inflation.
- The gap between the PBOC's daily yuan reference rate and market forecasts. A widening gap would show Beijing is steering the rate despite its statement.
