The price of gold keeps surging this week to more than 1500 US dollars per ounce, due to persistent weakness in the U.S. currency.

And some analysts even predict that the upward trend may last for four years more, with the price eventually rising to 1700 US dollars an ounce.

The U.S. Dollar has weakened significantly in recent months, and the U.S. Dollar Index has hit a 16-month low.

As a result, gold prices hit a historic high of US$ 1,505.55 per ounce before closing at US$ 1,500 per ounce on Wednesday. Silver prices, meanwhile, hit a 31-year high of US$ 44.50 per ounce.

Gold deposits have also risen, and the Bank of Taiwan's per-gram gold deposit sell price also reached a new high of NT$ 1,410.

Investors are selling gold to make a quick profit, but many have reservations about buying gold while prices are high.

According to Central Bank of the Republic of China statistics, Taiwan's gold to foreign exchange ratio remains higher than that of China or South Korea, and stands at just under 5%, or 13.62 million ounces.
