In their annual report 2015 the IMF stated that the world official holdings in gold are 30.506 ton (980.800.000 ounces) as per 2009. This is very remarkable, because in their annual report 2014 the world official holdings in gold were 27.346 ton (879.200.000 ounces). In the annual report 2015 there is no explanation for the difference of 3.160 ton (101.600.000 ounces) with a retrospective effect to 2009.
