Will the mystery official buyer of gold please step forward?
The World Gold Council's (WGC) third-quarter demand report on Thursday showed central bank buying reached nearly 150 tonnes, far above most analysts' estimates, but the buyers were not named.
According to an analysis by Reuters of IMF data, previous buying patterns and delays in data reporting, the most obvious candidates are China and India.
