The Bank of Thailand plans to tighten regulations on online gold trading. Central bank officials said the move was intended to curb the impact of wide swings in gold prices on the Thai baht, improving transparency without discouraging gold trading. Starting in March, online gold transactions in Thai baht will be capped at 50 million baht ($1.6 million) per user per day. Transactions exceeding that limit will need approval. The rules won't apply to users holding more than 50 million baht worth of gold before the end of January. Bank of Thailand Governor Vithai Ratanakorn said the regulations will also help combat money laundering.
