Russia being perhaps the wealthiest and most powerful nation currently under economic sanctions. Is it possible russia is buying up global reserves of gold in an effort to circumvent global sanctions?
Another nation which has scaled up its gold mining operations in recent times is china. There have been recent headlines claiming the united states is imposing trade sanctions on chinese exports. Perhaps there could be some connection there.
Aside from those obvious candidates, I was thinking that perhaps central banks could be purchasing gold. There have been media sources which claimed it could be a current trend.
Could it be they're preparing for a gold standard currency to rival the dollar and euro on a global market? I mean, it didn't go well for anyone trying to do that (Gadafi is one of the latest examples). But China and Russia might be giving it a shot.
