The Russian Federation‘s energy chief Pavel Zavalny has floated the possibility of accepting Bitcoin as payment for its oil and gas from “friendly countries” such as China and Turkey.

He said those countries could begin paying for energy in Russian rubles, Chinese yuan, Turkish lira — or even Bitcoin

 — rather than the international standard, United States dollar.

According to Russian news media RBC, Chairman of the State Duma Committee on Energy Zavalny stated at a Thursday press conference that he and representatives from China and Turkey have been discussing changes to preferred settlement currencies for its biggest export.

“We have been proposing to China for a long time to switch to settlements in national currencies of rubles and yuan. With Turkey, it will be lira and rubles. The set of currencies can be different, and this is normal practice. If there are Bitcoins, we will trade Bitcoins.”

He further stated that “unfriendly countries” could pay for their oil in rubles or gold. However, it is not clear whether Russia can change the terms of existing contracts with countries that pay in euros or USD.

Russia has been exploring ways it can circumvent international economic sanctions levied for invading Ukraine. Russian banks have been removed from the SWIFT system to prevent them from settling cross-border payments, and most businesses have been prohibited from dealing with Russia, except for oil and gas trading.

Energy is the single most important commodity that Russia exports — and is a key energy source in Europe and other countries, which have found it will be difficult to replace. According to Reuters, the oil and gas trade provided $119 billion in revenue for Russia in 2021.

Including electricity, kerosene, coal and natural gas, the energy trade accounted for 53.8% of Russia’s total $388.4 billion in 2021 exports, according to Russia Briefing.

The crypto market appears to have reacted positively to the news of an expanded international use case for BTC. Bitcoin is up 2.5% over the past day and is now approaching 30-day highs, trading at $43,917, according to CoinGecko.

CEO of Blackrock Larry Fink, the world’s largest asset manager, could be watching his prediction of a new digital payment system come to fruition before his eyes. Fink wrote in a Thursday letter to shareholders that global political instability could pave the way for nations to adopt digital currencies as international settlement tools.
