Several factors influence gold prices (mainly the US dollar, gold ETF inflows/ outflows, inflation rate, bond yields, safe haven demand, physical gold demand, gold supply) but none is more reliable than real interest rates.
The demand for gold moves inversely to interest rates — the higher the rate of interest, the lower the demand for gold, the lower the rate of interest the higher the demand for gold.
“Native silver” found in the Earth’s crust on its own, is relatively rare. More commonly, it is mined alongside gold, or as a by-product of zinc-lead ore. There are currently only 75 “pure play” silver companies, most of whom have projects in Chile, Argentina, Mexico and Peru.
The rarity of silver and gold becomes apparent when we consider how little of both have been mined throughout history – just 190,000 tonnes of gold and 1.6 million tonnes of silver. Or in ounce terms, 6.1 billion oz of gold and 51.3 billion oz of silver. All the gold ever mined in the world could fit into a cube 21.6 meters on each side, and all the above-ground silver could fit into a 55m cube.
