“Until a whistleblower speaks, we cannot know for certain, but my conclusion is that the Fed understands that it must protect the dollar from being driven down by QE and that the orchestrated takedowns of gold are part of protecting the dollar’s value, and perhaps also the cutback in QE is a part of the protection by signaling an end of money creation. The Fed also understands that it cannot forever drive down the gold price and that it cannot forever pour liquidity into stock and bond markets. To retreat from this policy without crashing the edifice requires successful orchestrations. Therefore, we are likely to experience more of them in the days to come.”
