Gold prices surged to a new 25-year high above $725 an ounce Thursday, on inflationary worries expressed by the U.S. Federal Reserve.
Persistent concerns about Iran's nuclear ambitions also lifted the metal, which is viewed as a hedge against currency weakness, inflation and geopolitical instability.
The June gold contract rose as high as $728 an ounce Wednesday on the New York Mercantile Exchange, its strongest level since 1980. It eased back in morning trading to $726.50, up $20.80 on the day.
The gains came despite the dollar's modest recovery against other major currencies after the U.S. Federal Reserve lifted interest rates to 5 percent and left the door open for further hikes.
Gold investors focused instead on the inflationary fears expressed in the Fed's statement and on the possible inflationary impact of surging prices of crude oil prices and industrial metals, traders and analysts said.
"Inflationary expectations seem to be rising in the U.S. and you could argue some of those expectations are coming from rising commodity prices," said Robert Rennie, chief currency strategist for Australia's Westpac bank.
Gold continues to garner support from concerns over the implications of a showdown between Iran and the U.S. over Tehran's nuclear ambitions.
At the same time, speculation that China and other Asian countries may be turning to gold as a way to reduce their foreign reserve holdings mostly denominated in dollars on a weakening U.S. dollar is also spurring investor sentiment, participants said.
