A whole lot of factors coming together imo; to look for a specific cause is the fallacy of scientism when applied to human affairs. Gold market player's reaction to the Blanshard lawsuit is certainly helping boost things overnight.
It wouldn't surprise me to see gold pushing $400 before March, maybe even within two weeks!
That's unknowable, despite what the technical analysts say. ;^)
1) I was not asking for a specific cause, just speculation, as you provided in your answer.
2) I thought Blanchard had made a big deal about how they were leaving the gold-selling business, circa 2000, all but apologizing for having recommended that its customers buy gold for an investment. Has that changed? If so, when did that change?
