Joel,
 Luke is telling us China's capital account is partially open via gold. A country's capital account:
      Â
 represents the balance of payments with other countries,
·        tracks the changes in a country's assets and liabilities in a year, AND
·        informs others whether a country is an importer or exporter of capital.
China’s manufacturing exports are at 30 highs which means their USD inflows are at 30 year highs. China/Chinese buy gold and oil. As China/Chines buy gold, gold’s price rises in CNY. China exports manufactured goods but must import oil, and other raw materials.
Since 1973 or so, oil and gold were priced in USD. When China had to buy oil in USD and the oil price rose, the value of CNY dropped against the USD and oil was much more expensive to China/Chinese consumers. Â China had to sell is foreign reserves held in USD to pay for oil. When those reserves are exhausted, China/Chinese had a CNY currency crisis. CNY collapses.
If CNY rises in gold but gold is priced in USD and gold  doesn’t rise because the gold price is set in London, then the CYN falls in value to the USD which makes oil much more costly in CNY.
If oil and gold rise in USD, then China has to sell its foreign currency reserves (USD) to pay for oil. When the FX reserves are exhausted, China can not import oil or other commodities and a currency crisis develops.
Luke is saying that today, the marginal barrel of oil and marginal commodity ton is priced in CNY and gold.
If CHY rises in value with the price of gold, then gold and CNY buys more oil and other commodities than in USD in the USA, GB or Europe. The USD falls in value to the CNY and Ruble and energy becomes more expensive to the USA/consumer.
Biden has attempted to reduce oil prices by releasing oil from the SPR.
Russia, KSA, Iran (Venezuela if it resurrects) etc. all accept CNY for oil and NG (Russia actually discounts the price of oil to China if payment is in gold.
This discount in energy prices is a tremendous economic advantage for China. I am reading in other publications that the cost of reshoring manufacturing and building high tech plants and facilities is 5-6X greater in the USA Â than the cost in China. BOOM!
Luke says that gold is simply another form of capital. It gold has more value in China or Asia or Russia or KSA or Iran, then gold reserves in London/New York will move to new to new depository  destination in China and Moscow and elsewhere.
If the pricing of gold and symbiotically oil/energy moves to China instead of London or New York then what will happen to the USD/CNYÂ or the USD/RUB or the USD/EUR relationship?
Â
According to Luke, gold is the new currency for the BRICs. Energy will be priced in gold and the USD will be devalued to reflect this.
This country is going to need every hydro carbon molecule it can get for its own capital account.
This is why I think the Permian basin will be squeezed like a lemon or lime on a hot summer day.
I hope I am at least half way correct and that this helps. I hope other readers understand it better than I do.
