On June 17, we wondered whether the "parabolic blow off in gold accumulation by ETFs is about to cause a gold price explosion?" Sure enough, yesterday, Goldman Sachs came out with a bullish report on gold in which the firm stated that should gold purchasing by ETFs continue at the recent pace, then gold at $1,400 is a virtual certainty. A quick look at the closing NAV in the gold holdings of GLD, as a proxy of the broader Gold ETF community, indicates that $1,400 - here we come. Just overnight, GLD added another 5.2 tonnes of gold, bringing its new total to a fresh all time high of 1,313.13 tonnes, a whopping 76 tonnes higher than a month ago. As the indexed chart below demonstrates, what we thought could become a positive feedback loop whereby non-physical ETFs scramble to at least catch up to a par NAV, is already in process: the ETF accumulation by GLD, which is now the 6th largest gold-owning entity in the world, has become a self-fulfilling prophecy. If the ETF is indeed purchasing said gold in the open market, there is no way this would not be moving the price much higher, absent massive synthetic shorting by the LBMA. Yet at some point, internal risk controls at even a firm with infinite margin like JPMorgan will take over, and force the bank to cover its record short exposure. When that happens, the already disclosed demand by entities such as ETFs and Central Banks, will catch up with the most manipulated and distorted supply curve in the history of economics.
