Not at all. The economic fallout of Russias takover of Ukrane will have about as much impact on the world's finances as the Russian takover of Hungary in 1956.
There will be much hot ir blown, otherwise, no impact.
IMHO this is a pretty unique situation, with Russia having a major southern naval base there, and so many ethnic Russians. Nevertheless it is a long term loosing position for Putin and Russia no matter what option they choose, both economically and politically.
In spite of calls from some US politicians for 'action', there wont be sanctions or anything else other than some symbolic G8 (G7?) meeting posturing, freezing some mostly symbolic transactions, etc. Both sides know they are not the only ones who get to move the chess pieces here.
Even now the Russians are seeing the economic effects in their falling markets and currency. And both the other European countries and Russia see the disaster a trade war would have.
Long term this is really bad for Russia, tips their hand (heavy hand) and makes their neighbors even more wary of ties with them. There will be more long dislike of Russia in Ukraine and an even stronger desire to be allied with the west.
Short term it makes Putin vastly more popular in Russia (they like strong shirtless leaders apparently), so short term is a plus for him. But he has to stop short of disturbing the economic conditions to severely or risk tipping Russia into a deep recession.
Other than as a source for raw materials and gas and oil, Russia is not too critical to the world economy, so I doubt there will be much economic impact in the west, assuming the west and Ukraine will still keep buying Russian energy resources.
We have been in much much greater areas of differences with Russia in the past. This is pretty localized and will likely remain so.
On the other hand... It made no sense for the assassination of a minor Austrian archduke to start a world war either. So I guess when you assume that people or countries will act in their best long term interest, you have to take it everything with a hopeful grain of salt.
