I found some lead price charts also, but not the "Why".
Supply vs demand under the constraints of environmental scrutiny with lead as a pervasive evil.
Would you be so kind as to say whether you agree, or not that Shell might be a good bet? You previously posted, "At this point, is there any reason NOT to be long oil?" But seemed possibly contradictory in your link reply to me.
TBH I don't know the ins and outs of Shell specifically.
But consider this.
Some estimates have the world's energy needs doubling in a decade or so.
Without energy, civilization comes to a halt.
Globally, passenger vehicles account for only something like 25% of crude oil usage.
Now factor in population growth + greater demand for passenger vehicles + global shipping + domestic shipping etc.etc.
Now imagine what is going to happen to prices with oil being treated as public enemy #1
+ increasing extraction costs
+ declining production of current oil producing arenas
+
institutional policies, both in the public and private sector, that prohibit investment or lending to companies engaged in fossil fuels.
+ price volatility i.e. production running at or below capacity in the face of global conflicts leads to much more sensitivity to supply disruption
All this in a world of increasing population and increasing energy needs where people still have to eat and goods have to be shipped.
