Various governments have messed up the whole earth’s fossil fuel market.

Has this happened before?

Here in the USA in the period 1914 to 1919
the price of “Nut & Slack” sized coal loaded in a railroad car went from
$0.5 per ton to $20 per ton

{at this time a troy ounce of Gold cost $20.67}

40X

In 1971 to 1975
the price of N&S sized coal loaded in a railroad car went from
$8 to $40 per ton

{at 1970 a troy ounce of Gold cost $36 until Richard Nixon “temporarily” suspended the Gold window of currency exchange}

In this recent episode, last year
coal loaded in a seagoing boat in Newcastle, Australia went up
from USA $60 per metric Tonne
to USA $270 per metric Tonne
Both China and Russia government “supreme leader” decisions contributed to this increase.

{ a Troy ounce of Gold varied $1700 to $1940 on markets}

China wanted to punish Australia for publicly demanding truth about the origin of an infectious disease.
China’s effort backfired.
Australia simply found other ready buyers for the coal.
China found out that other coal suppliers demanded more money for inferior coal.
