With a tariff and a 100% domestic supply(big assumption) we would pay whatever the cost of getting out of the ground plus refining, piping and retail. Somehwere around 50 per bbl.
I don’t think that it’s a big assumption that the USA can supply it’s own domestic demand for oil ... because the USA was already on its way to being the largest oil exporter in the world (I already posted many articles on that) ... UNTIL ... Saudi Arabia decided to “crash the party” with oil so cheap that it bankrupts American producers.
Oh ... one more thing ... don’t forget to include a SIZEABLE PROFIT to that equation, as these companies are in this business for profits, and not merely to cover costs ... :-) ...
