I used to believe strongly in financial sanctions over war but I'm becoming more skeptical. Markets and industry are a very hard thing to constrain at a global scale. To do it effectively you basically encourage a giant financial surveillance state and need put huge pressure on partner countries - who often don't even implement it meaningfully. You make business harder for everyone and create lucrative black market organize crime business.
Military action is appearing more preferable to that.
For example:

> In the wake of the February 2022 invasion, Ukraine's allies imposed sanctions on Russian hydrocarbons. The US and UK banned Russian oil and gas, while the EU banned Russian seaborne crude imports, but not gas.
> Despite this, by 29 May, Russia had made more than €883bn ($973bn; £740bn) in revenue from fossil fuel exports since the start of the full-scale invasion, including €228bn from the sanctioning countries, according to the Centre for Research on Energy and Clean Air (CREA).
> The lion's share of that amount, €209bn, came from EU member states.
Meaning 3 years into the war Europe is still sending more $$ to Russia for gas than they send Ukraine in aid
