Gold continues to lead the precious metals rally, reaching new all-time highs in multiple currencies including the US dollar at $2,771/oz, while silver lags behind at $30.57/oz with a gold-silver ratio of 90. Major supply constraints are emerging in the silver market, with US refineries facing three-month backlogs for COMEX Good Delivery Bars and industrial consumers struggling to source reasonably priced physical silver, amid a reported billion-ounce supply deficit over the past six years.
