In a statement by the US Treasury secretary, Janet Yellen, she disclosed that this price cap initiative could help restrict Putin's finances and put a hold on the revenues he generates to fund the senseless and brutal war.
With Russia's economy experiencing a contraction and it's budget increasingly getting thin, this action could cut into hispst important source of revenue.
Measures like this taken by the EU are no longer new to the public, because since the war began, they have been seeking for ways to stop him from this mindless attack, but efforts have proven futile. How long will the EU continue searching for 'new and improved' methods to stop him, or is this it?

Agree with your post that the price cap initiative would help Russia gain more capital. To complete the demand and supply and all the efforts for stopping other countries from buying the cheap as it's its perception that preference of buying lower price would prevail against restrictions by other countries.
