Taking the current spot price of $1,321.15 per troy ounce, gold purchases by central banks in 2018 amounted to a $27.7 billion spending splurge on the precious metal.
“Heightened geopolitical and economic uncertainty throughout the year increasingly drove central banks to diversify their reserves and re-focus their attention on the principal objective of investing in safe and liquid assets,” said the report released on Thursday.
The WGC said the bulk of the buying was carried out by a handful of central banks with Russia leading the way as it looks to swap out dollars from its portfolio. The Russian central bank sold almost all of its U.S. Treasury stock to buy 274.3 tons of gold in 2018.
The central bank of Turkey increased gold reserves by 51.5 tons in 2018. That marked a second consecutive year of net purchases but was 40 percent lower than the volume it bought in 2017.
Other big central bank buyers were Kazakhstan, India, Iraq, Poland and Hungary.
Net sales of gold from central banks remained small, totaling less than 15 tons. Australia, Germany, Sri Lanka, Indonesia and Ukraine accounted for almost all of that figure.
WGC said total gold demand in 2018 reached a total of 4,345.1 tons. The biggest demand came from jewelry which, while flat on the 2017 figure, accounted for just over half of the total. Bars and coins contributed 1,090 tons in 2018, marking a 4 percent rise from the previous year. Gold used in technology climbed marginally to 334.6 tons.
The price of gold has risen around 9 percent in the last three months.
