The gold silver ratio (GSR for short) is the number of ounces (oz) of silver required to buy one ounce of gold (i.e. price of 1 oz silver / price of 1 oz gold). It is used by gold and silver traders to determine when to buy or sell the two precious metals. Unlike most other ratios where there is a generally accepted number or a range of numbers, the GSR has none. One oft-quoted number is 17.5, which is the amount of silver to gold in the Earth’s surface. However, based on the last 30 years or so, the ratio did not even hit that number, and the lowest was back in 2011 where the GSR was slightly above 301. Though these two are precious metals and have a high positive correlation with each other (0.79 between 2007 and 20182), the GSR swung wildly between the 30s and 80s...
