It's been speculated for a time whether or not the US and its allies would sanction Russian oil and gas. Here's your answer. The EU appeared to be dead against it.
This is negative for oil and gas.
The full comment from the White House's Deleep Singh:
"US measures are not designed to reduce or impair Russia's ability to supply energy to the world but we think it'd be a strategic mistake for Putin to weaponize his energy supply because it will accelerate world diversification away from it"
So the US and Europe is more worried about Putin hitting back on other sanctions by limiting oil & gas exports.
Along along with USD/CAD are unmoved by this.
Update: Singh also says the US won't attempt to remove Russia from SWIFT.
So what is really at stake here? Some individual sanctions and sanctions against Russian banks? That might be tough for them but is it really a factor for the global economy.
