The Central Bank of Russia was the biggest buyer, purchasing 16.55 tonnes. September’s addition marked a 20th straight month of buying for the CBR, which hasn’t seen reserves fall since January 2015 when its holdings dropped by 0.48 tonnes.

And Russia’s central bank was not the only one buying, China and Kazakhstan saw their gold holdings increase by 4.98 tonnes and 4.14 tonnes, respectively, the WGC said. Interestingly, September’s three notable buyers are the only central banks that have seen their holdings increase in 2016, and that isn’t expected to change anytime soon.
