To your first question, Biden's closing of the Keystone XL pipeline and stopping all drilling on federal lands contributed significantly to the shortage and price increase of crude oil.
I posted 4 long-term charts to allow for historical perspective and rationale. For arguments sake, let us assume that rather than closing the XL pipeline, Biden waved a magic wand and, 'hey presto', a fully operational XL pipeline appeared.
Do you seriously contend that this would have affected the 'exponential'* rise in the world price of crude oil ?
As to the increased cost of container shipping, that was caused by the rush to move various goods across the globe and botched up shipping logistics as many ships sailed empty back to China to pick the next batch of masks and other PPE products.
No, 12 month charter rates did not increase 10-fold because of the PPE shortage. The long term rates increased as a direct result of the sharp upturn in IP and the limited supply of world tonnage. A situation persisting today.
As to the rise of rouble, its current strength is completely detached from the state of Russian economy and is the result of the Russian government actions which propped up the rouble to avert the market collapse,
Well they didn’t prop up the rouble. Once the majority of the sanctions had been applied, the Ruskis turned round and required payment for their raw materials in, surprise, roubles instead of dollars! With the limited supply of roubles, the value of the currency reversed its trajectory and them some - resulting in the strongest USD/RR exchange rate for over 5 years.
What you described, are 'currency controls' designed to stop a 'run' on banks and currency flight. The result here was the opposite.
