The Russian troops have been deployed on the Ukrainian border in more than a dozen strategic locations. For weeks, Putin and other Russian officials have held the narrative that NATO is a threat to their security and they don't want to see it expand in the area anymore. It seems there is a need for a catalyst, aka Ukrainians are throwing missiles into pro-Russian kindergartens and schools. Subsequently, I suspect Russian troops will invade Ukraine as early as the beginning of March; due to the more favourable climatic conditions.
A war in Europe will negatively impact currencies like CHF, GBP and the Euro.
