Reuters — Gold prices are currently high and markets should be careful of a potential asset bubble forming, a senior official at China’s central bank said on Wednesday, as prices for the precious metal hit a record high.

“We must keep in mind the long-term effects when considering what to use as our reserves,” Hu Xiaolian, a vice-governor at the People’s Bank of China, told reporters in Taipei, when asked if China had plans to increase its gold holding in its foreign exchange reserves.

“We must watch out for bubbles forming on certain assets, and be careful in those areas.”

Gold hit record highs at US$1,216.75 an ounce in Europe on Wednesday as investors bet on higher prices.

China’s more than US$2-trillion in foreign exchange reserves are mostly parked in U.S. treasuries, despite calls from some in China to invest the reserves in oil and other natural resources that the fast-growing Chinese economy will need in future.

Before gold prices hit record highs, however, China said last month that it is working to improve the allocation of assets in its foreign exchange reserves, when asked whether it would buy any of the gold that the International Monetary Fund is seeking to sell.

SINGAPORE — The U.S. dollar continued to tumble against most Asian currencies Thursday, prompting a wave of foreign-exchange intervention by central banks in South Korea, Taiwan, the Philippines and Thailand seeking to limit damage to their export industries.

Traders said the dollar selloff is unlikely to fade soon, given the prospect for a long period of low U.S. interest rates to support a sluggish U.S. economy and increasing signs central banks in Asia will begin tightening monetary policies in the months ahead.

Surprisingly strong employment data in Australia bolstered speculation the Reserve Bank of Australia — which Tuesday became the first among Group of 20 central banks to raise rates — will deliver another increase before the end of the year. The news pushed the Australia dollar up sharply, and intensified buying of Asian currencies against the U.S. dollar.

“Investors need little encouragement to extend selling of dollars, but received two further green lights today in the form of ongoing weak U.S. consumer credit and a stunningly strong Australian employment report,” said Patrick Bennett, a strategist with Societe Generale.

The U.S. dollar’s downside against Asian currencies is “being slowed by intervention, but consolidation or rallies are opportunities to establish or add to shorts,” he said.
