What I do not like is that the most civilized nations over the world start to grab Russian money. The effect is just the opposite. All the bank asset freeze triggers cross-default. If one bank does not pay the other, the other won't pay the rest. Then a lot of businesses default.
Also, a lot of US and European investments on Russian mutual funds, ETFs and hedge funds. West investments in Russian assets are far greater than Russian investment in Western assets. Russia is in several of the index funds too. Also global equity index and a lot more. All of those investments and related derivatives are effected.
We'll see a lot of news on this.
