Noman’s monthly $XAU:$GOLD chart is an impressive piece of work IMO and I think it deserves further examination.
Here is a look at the movements in $GOLD and $XAU in parallel with the ratio.
You will note that the two largest $XAU corrections occurred when the $XAU:$GOLD ratio turned down shy of the 80 mark.
Notice that no impulse rally resumed until the ratio turned up again after hitting the 20 mark, or nearly so, with one exception – in March 2020 when the ratio turned up at the 50 mark. That dive in March of this year was enough to shake the confidence of most PM bulls.
In any case, I don’t believe the near term inflation/deflation debate is yet decided.
