The price of gold has risen above $US1,300 an ounce for the first time.
The precious metal rallied to $US1,300.07 during trading at the London bullion market before easing back, the BBC reports.
The price has increased five-fold in the last 10 years, from a low of $US258 in 2000.
The latest rise has been spurred by caution over the global economy.
Gold is regarded as a safe haven by investors worried about inflation. The BBC reports there is concern that inflation may grow, in time, as several leading central banks have tried to stimulate economic recovery with policies that increased the money supply.
Weakness in the US dollar - the currency used to value gold - has also contributed to the price rise. The US currency fell 1% against the euro.
