> Well, there's a risk of a Russian default now.

I think that risk is 100% as in it's a certainty that Russia will default. Defaulting means not making loan repayments. The ruble is basically worthless so they don't have much to repay their debt with and they can't sell assets to raise the money due to sanctions. Another aspect to consider is that they probably are eager to default at this point as doing so could cause financial damage in the West.
