Famous economists write a letter to Janet Yellen
Here is the letter, they argue for a price cap on Russian oil and gas:
As envisaged by the G7, the price cap would set a maximum price that Russian oil could be traded in conjunction with G7 services. This price, set in dollars, would be substantially below the world price, yet above the marginal cost of production in Russia. To use US, UK, EU, and allied financial services (such as insurance, credit, and payments), market participants will need to attest that all qualifying purchases are at or below this threshold.
Given the importance of participating countries for global finance and for shipping, compliance with this cap will create pressure for a lower price on Russian oil moved by tanker. While we do not expect all trades will be performed under the price cap, its existence should materially increase the bargaining power of private and public sector entities that buy Russian oil.
The price cap maintains economic incentives for Russia to produce current volumes. In April 2020, when the price of the Brent benchmark was close to $20, Russia continued to supply oil to world markets, because that price was above the cost of production in many or most existing Russian oil fields. Russian has little or no available onshore storage, and since shutting down and restarting oil fields is expensive and risky, it was more profitable for Russia to continue producing in the presence of low prices. The price of Brent now is around $96 per barrel, but Russia receives significantly less due to the “Urals discount”. This discount is caused by the perceived stigma of buying Russian products for some customers; they decline to bid for Russian oil, which reduces effective demand and lowers the price that the remaining customers need to pay.
The oil price cap proposal would effectively institutionalize the Urals discount and consequently further lower the dollar value of the Russian government’s primary revenue stream.
