World gold rose about 4.1% on 5 Aug to around $4,247/oz, its biggest move in seven months, after signs of progress in US-Iran talks that could reopen the Strait of Hormuz and lower US bond yields. The Thai Gold Traders Association raised the domestic gold bar price by 1,900 baht to 67,150 baht (jewellery 67,950 baht). Analysts note foreign investors have been net sellers of Thai stocks.
