The capping in the metals is obvious.
There is no economic news or theory that is needed otherwise to explain it.
The question is how long it can last.
Have a pleasant evening.
“Behold, God’s dwelling is with mankind;
he will dwell with them.
They will be his people,
and he will be their God,
God-with-them.
He will wipe every tear from their eyes,
and there will no longer be death.
Neither will there be any mourning or crying or pain,
for the old order has passed away.”
Revelation 21:3-4
