That's how a Wall Street analyst would describe the relationship, same as airline stocks are sensitive to oil prices, one goes up, the other goes down.
And ya better hang on to your hats, cuz there's a storm brewing.
Trump administration is threatening to get tough on Iran sanctions, they want to completely take Iran oil off global market. That's about 1.5 to 2 million bbl per day.
Sauds can make this up, if they want to. But even if they do, we get back to the days pre 2012, where there is no spare capacity. So everytime there's some geopolitical dust up, the price of oil spikes because no producer can bring any more oil to the market to replace a disruption.
And to further complicate, OPEC meets again in June to review their current quotas, that could be an interesting meeting as Saudis will have lost their leverage.
Get ready to pay more at the pump, IDK how much , or how soon, and hopefully this won't last long. But to me, it does not look good. Hopefully, USA will begin putting more oil on market from the Strategic Petroleum Reserve, we really no longer need that, anyway.
