Thai gold bar prices fell 700 baht on 31 Aug to 69,550 baht, and gold jewellery sells at 70,350 baht, after a 1,600-baht drop on Saturday. The drop follows a stronger dollar and higher US bond yields after Fed Chair Kevin Warsh's Jackson Hole speech, which lifted markets' odds of a September rate hike from 35.4% to 56.9%. Hua Seng Heng sees a short-term rebound with resistance near 70,400-70,700 baht. For a shop holding gold stock or taking gold as collateral or payment, prices are volatile, so avoid large buy-in or sell-off decisions based on one day's move.
