"While it is true that derivatives commonly referred to as “futures” or “paper-gold” have been heavily used to suppress the gold price – let it be known that physical gold bullion [or something that can pass as physical gold bullion] is still required in the settlement process to make the highly leveraged paper sales appear credible.... ...As such, observable physical inventory... or something that “can pass” for being as much is vitally required at ALL TIMES."Good news for your gold bars: Olympus tells us "Gold bullion bars have been fraudulently adulterated through the insertion of slugs of inexpensive base metal of similar density. These insertions are difficult or impossible to detect through weighing, radiography, or X-ray fluorescence, so some precious metals processors have resorted to drilling or cutting bars to verify integrity. However a simple ultrasonic test can quickly and reliably locate inserts with no need to drill, cut, or otherwise alter the bar." Hat-tip Zero Hedge.
