Response to Rod ...Your question is logical given the level of US government debt, high inflation and energy prices, central banks buying up gold to move away from the USD, war in the Ukraine, China entering bi-lateral currency / trade deals, etc. The world is indeed scary but a reserve currency doesn't collapse overnight. Look at Japan. It has stumbled along for close to 2 decades now. Only now is the debt levels finally making the BOJ start lose control of their 10 year JGB yields. Once the rate goes above their 50 bps target rate then watch out.
Back to the USD ... it will remain the reserve for the world for the foreseeable future but marginal erosion of its dominance can be seen. All the above the reasons plus the big one ... OPEC doesn't care what the US thinks anymore (e.g. latest OPEC production cut) ... if oil starts getting bought and sold in other currencies in a major way then watch out. Again, you need a viable alternative which currently doesn't exist but smaller bi-lateral deals are happening.
So my recommendation is that everyone should hold some gold in their portfolio. 5% to 10% depending on your personal circumstances. To be a true hedge you need to have physical gold (which has storage issues and you need to pay GST to buy in Canada). Alternative, is to buy gold mining majors like Newmont or Agnico. You can also consider Wheaton which is the a great royalty streamer.
