A few years ago, $1.30 was believed to be a trigger for more easing by the Fed. Clearly, the situation has changed in recent months where in March 2015 the talk is for the US$ and Euro to reach parity.

Wikipedia defines the LBMA as:
The London bullion market is a wholesale over-the-counter market for the trading of gold and silver. Trading is conducted amongst members of the London Bullion Market Association (LBMA), loosely overseen by the Bank of England. Most of the members are major international banks or bullion dealers and refiners.
COMEX provides an explantion of the COMEX delivery reports (settlement of long/short positions which may not involve any movement of gold) and observes that COMEX delivery should not be compared to warehouse inventory report. COMEX delivery volume is analgous to the Au(T+D) Delivery Volume (aka Settlement Volume) on the Shanghai Gold Exchange.
It is unclear to me however if the COMEX warehouse inventory report changes can be understood as a physical deliveries out of the COMEX system of warehouses. Perhaps this isn't an appropriate question since the COMEX is primarily a paper/derivative market and is not the place anyone would go to physical gold. However, that said, Shanghai Gold Exchange reports very clearly show a large flow of gold into China and that gold has to be coming from somewhere. Is some of the COMEX gold being drained into China?
