Excellent. El Trumpo!
Russia’s oil exports are 7.4 million bpd. Only Saudi Arabia comes close to that.
China’s oil consumption is 16.4 million barrels/day and as of the latest official numbers, that number grew 10% from the previous year. This is well past Covid. It is not virus recovery adding to consumption.
China’s oil production is about 4.5 mbpd. That means they are importing 12 mbpd.
Russia’s pipelines into China have about a 3 mbpd capacity. The conduit to India is another 1 mbpd. The rest is tankered, or actually more often, it is intermixed in Kazahkstan with Azerbaijani crude and sent east to China in the Kazahkstan-China pipeline (the capacity of which I do not know off the top of my head, about 1 mbpd is my recall).
This would add up to about 5.5 mbpd of the 7.4 mbpd Russia currently exports.
I can’t see how these new sanctions will matter, which is besides the reality that Russia has its own Central Bank that can QE a few billion dollar equivalents per year without stressing anything, given their small debt/GDP ratio compared to the US.
