World gold rose to about 4,540 USD, a high in over two and a half months, after the US Treasury signalled more bond buybacks, which weakened the dollar. Thai gold bars are back above 70,000 baht. The rally is fragile: long bond yields quickly climbed back (30-year to 5.25%), and US ETF holdings were net sellers for the year to date (down 33.08 tonnes). Shop owners who buy or sell gold for stock or pricing should expect volatility and avoid locking in large positions on a single rally.
