Thai gold prices rose about 100 baht on 19 Oct 2026 versus the previous close. Bar gold: buy-in 66,000 baht, sell-out 66,200 baht per baht-weight. Jewellery 96.5%: sell-out 67,000 baht, buy-back about 64,673 baht. The spread between buying and selling is wide, so a shop that buys back gold loses roughly 2,300-2,400 baht per baht-weight on the round trip. Global spot is around US$4,176/oz. Brent crude is about US$110 amid US-Iran tensions, which can feed into fuel and transport costs. If you hold gold for business or pricing, check the buy-back spread before you trade.
