(Kitco News) - Gold and silver prices are holding sharp gains near midday today, boosted by a steady-weaker U.S. dollar index and a dip in U.S. Treasury yields at mid-week. There’s an old trading adage that says markets will do anything and everything possible to frustrate the largest number of traders. Such appears to be the case at present in the safe-haven metals: They sell off on keener risk aversion and rally on better risk appetite. Apparently, the metals traders on this day are focusing more on inflation prospects receding if the war in the Middle East de-escalates. And veteran gold market watchers also remember when their metal used to rally on inflation fears. April gold was last up $155.70 at $4,557.90. May silver prices were up $3.521 at $73.125.
