Norwegian Krone crashed to a ten-year low today, as well.
The Krone was the proxy for the ruble since the west stopped trade in rubles. And since the Krone had not been affected by massively jacked up interest rates, it could only go down. You cannot squash Russian oil producers by lowering the ruble and the price of oil in dollars simultaneously. That is just more stupidity out of Europe and the US. Russians oil cost to produce is in rubles not dollars. You can only hurt the Russian people and oil producers with cost tied to US dollars in that idiotic scenario.
