Thats pretty much my thinking. Not that the ratio really relates to accuracy of anything but its mostly likely that gold is undervalued and behind the curve in its appreciation.
Silver is used in solar polar, its a very useful practical and efficient metal. Its special in all kinds of ways and in addition it might be used for some secondary monetary use however its primary use is industrial and it will always be mined incidentally and in quite great amounts. Any spike in silver is going to be in the tail end of a system which has lost its integrity, most of us know this is possible now.
In recent years silver is less used, less base demand due to photography. Digital cameras use far less silver and none at all in used to create the actual photos of course. Printers use little silver and none in the ink that Ive ever heard of. The rise of electric power is its most likely future growth industry, it has a unique place there so Ive read. There is a big tech release of a new battery recently, its not using silver in that design not sure but I think silver will be relevant in some quantity
The other noble metals are often related in demand to car production for pollution and emissions reduction
Apart from gold and platinum, there are also other bullion metals such as palladium. I am not mentioning silver here, because I don't consider silver as a bullion metal. The majority of the silver mined every year is used for industrial purposes, and not for investment.
Palladium seems very stable. Ive read it is not suitable for monetary purposes as its not equal in its distribution. Russia has the vast majority of known reserves, in some crazy world Russia is the reserve currency maybe you will see this metal used for that.
Hopefully not because it would be equal to our system now where the main producer and controller of dollars is USA and they manipulate the market in their favour debasing worth and distorting capitalism
