I don't see how this could be sustainable, but it would raise a few questions.
Let me try to answer your questions.
One, if sustained, how much higher would US production go over the next 18 months?
I expect US oil production to increase by 1.2 mb/d in 2018. Combined with increases in certain other NOPEC countries, this could be enough to offset the increase in global oil demand, but there's a timing difference: Majority of US oil production increase will happen in 4Q18, while majority of global oil demand increase will happen in July. In any case, just offsetting demand jump in July will not be enough to balance the market, which is already deeply undersupplied. Expect oil prices to continue to increase throughout 2018.
Would this increase Tesla pricing flexibility or drive more demand?
Yes to both. I expect an acceleration of demand for all things Tesla throughout 2018. Model 3 will remain supply-constrained for some time, not only at $60,000 ASP in 2H18, but also throughout 2019, even after the full expiration of the Federal Tax Credit.
They can't really make them any faster, so not sure this matters to Tesla.
It does, because it allows Tesla to keep ASP at $60,000 in 2H18 and $52,000 beyond even as Standard Range enters production. Each $1/gallon increase in gasoline prices translates to additional $500
per year savings to the buyer,
AND higher gasoline prices mean stronger residual values for all Tesla vehicles,
AND reservations for Model Y and Semi will snowball,
AND higher energy prices in general mean higher demand for solar panels, Powerwalls, solar roof, and so on. All of this is crucial for revenue growth and profitability, and therefore, valuation multiples.
The biggest question is if they get $80 a barrel, how much could that speed up peak demand?
Higher energy prices accelerate the world's transition to renewable energy, so sustained $100 per barrel would pull peak demand forward, but I do not expect oil prices to remain above $100 per barrel for long. Surging energy prices will lead to a recession, possibly by the end of 2018.
Any pricing over $60 for the next 18 months is going to create more production investment in the US and anything over $70 is going to fund a lot of new production.
Production is not just a function of price, as oil market participants found out when prices plunged from $100 to $30. Once a well is drilled and completed, it doesn't take much to pump out the oil, so it's pump at will. This led to gross misunderstanding of oil markets: It was only nine months ago when the vast majority of pundits predicted oil prices would be "capped" at $50.
