Gold dives to 5-year low in sharp selloff on strong dollar

Gold plunged 4 per cent to its lowest in more than five years on Monday with platinum also sinking 5 per cent to its weakest since 2009 as investors sold the precious metals on the outlook for the US dollar.

It was a sudden, massive drop for gold and platinum prices as they breached critical support levels as the dollar strengthened on growing expectations that the US Federal Reserve will hike interest rates this year.

"It looks like someone was taking advantage of the low liquidity environment at the moment.

It's a bit of speculative selling going on," said Victor Thianpiriya, analyst at ANZ Bank in Singapore.

Nearly 900,000 lots were traded on a key contract on the Shanghai Gold Exchange, compared to less than 27,000 lots on Friday, Reuters data showed. Prior to Monday, volume for July had averaged less than 30,000 lots.

"The market looks very technically weak and the biggest buyer of all, China, is now selling gold as opposed to buying it on price dips.

That's a recipe for weaker prices," said Thianpiriya.

China said on Friday its gold reserves were up 57 per cent at the end of June from the last time it adjusted its reserve figures more than six years ago.

Despite the tonnage increase, gold now accounts for 1.65 per cent of China's total forex reserves, against 1.8 per cent in June 2009.

Spot gold was down 2.4 per cent at $1,106.90 an ounce by 0302 GMT after falling as far as $1,088.05, its lowest since March 2010.

Gold has breached key support levels as the dollar gained after Federal Reserve Chair Janet Yellen told Congress last week that the Fed is on course to raise interest rates if the US economy expands as expected. Platinum lost as much as 5 per cent to $942.49 an ounce, its weakest since February 2009. Palladium dropped as much as 3.4 per cent to its lowest since October 2012.
