CRB Index ending Diagonal - is the commodity cycle done ?

CRB Index has been trending steadily since the time the logistics issues cropped up along the Covid wave across countries , gaining additional impetus from the crude oil rally - ukraine war. However off late its a bit surprising that so many of the commodity shortage or panic demand factors are so quickly priced in , as the ending diagonal in CRB almost makes it certain by way of wave theory that a significant top is placed. This also shows the tendency to stay out of commodities as the central banks who have suddenly woken up to inflation - rather late are now not leaving any scope to increase rates.
