It seems you are speculating that Putin’s response to Oil & Gas sanctions would be to nationalize all bank accounts and therefore broad sanctions are the only measure that could work. Let’s say that were true. Why then should the west not apply broad sanctions AND include sanctions on Oil & Gas exports as well? It seems to me that this policy would shut down Putin’s war machine faster than either measure alone. I suspect the real reason the west chose to exclude oil & gas from other sanctions is the same reason the sanctions include a carve-out for selling Italian luxury goods to Russian elites. Namely that the west is equally willing to impose pain on the Russian people as it is on Russia’s elites but they are unwilling to take more effective action since it would be politically risky and may impede their chances of re-election - even though it would effectively end the war in Ukraine immediately.
