I think energy is the biggest economic issue with this potential conflict, both in terms of how it impacts short term supply chains but also if the UK/US start doing sanctions. For my portfolio the biggest impact is BP as my only energy holding, and because it holds a very profitable 20%+ stake in Rosneft a Russian company so will the UK govt look at that as an issue, also BP has lots of operations in Russia working with Russia and Russian companies.
However if it doesnt escalate and materially change the working arrangements then BP/Rosneft are very strong players:
Could be a bumpy ride for me
