The WGC, a non-profit association of the world's leading gold producers, said other big buyers of gold during the third quarter were the central banks of Turkey (18.5 tons), Kazakhstan (13.4 tons) and India (13.7 tons).
In Europe, the national banks of Poland and Hungary also ramped up gold purchases. According to the WGC, the latter has said the buying is to enhance the long-term stability of its reserves.
Gold is often considered as a hedge against any fall in value of the U.S. dollar. During the third quarter, the dollar index ticked up by around 0.7 percent.
Despite the appetite from several central banks, the price of gold fell around 4 percent during the period, slipping below $1,200 per troy ounce to hit its lowest level since January 2017. Bullion has since seen a positive month in October, rising by around 2 percent.
The WGC said that while central bank demand was complemented by more buying of physical bars and coins, jewelry and orders from technology firms, investors took flight.
Data revealed by the council revealed that selling of gold-backed exchange traded funds (ETFs) in the third quarter resulted in sales of more than 116 tons of the precious metal.
The overall net effect was that gold demand in the third quarter was 964.3 tons, 6.2 tons higher on a year-on-year basis.
