Putin says 'unfriendly countries' must buy Russian oil and gas in rubles.

[Slammer]

23. Turkish lira

That might have been a good idea at the beginning of the sanctions.

But now, the EU has barred countries from transferring Euros into Russia and the US has barred dollar transfers.

It's not going to have as strong of an effect for countries to go out and buy the Turkish lira or the Mexican peso and use that to buy rubles.

In fact, buying the Turkish lira might be a good idea. They're scrambling to stabilize their currency by bringing in foreign currency after having 73% inflation last year.

Use Turkish lira to buy rubles. Use rubles to buy gas and oil products.

Russia at the end of it is still stuck with a currency that'll lost a large chunk of it's value by the end of the year.
