The G/S ratio ranged between 60 and 90 (roughly) for the last 7 years. Prior to the silver boom around 2011, the ratio ranged between 50 and 80 for the prior decade (more or less). Looking at the historical chart for the last 30 years, outside of short lived spikes/valleys, the ratio seems to range steadily between 50 and 90 (seems like a huge range, but the charts show fairly steady slopes between the spikes). We are exiting a sharp spike in the ratio. It would seem that the ratio is likely to get range bound again for a while (maybe between 70 and 90?).
