Crude oil remains in a bull market for one primary reason: demand growth continues to run ahead of supply growth. Looking over the longer term, crude oil prices have reacted sharply each time supply growth has moved above or below demand growth. The commodity cratered after the second quarter of 2014 once supply growth sharply outpaced demand. The bear market didn’t end until the first quarter of 2016, once supply fell below demand growth. Today crude remains in a bull market, albeit a relatively tame one. The dynamics of supply versus demand are shown below for reference:

Looking at the chart above, growth in demand has been remarkably steady while supply has been much more volatile. Digging further into supply data, the biggest source of new supply has unsurprisingly originated from the US. For visual emphasis, this is shown below:

American shale ruins the OPEC party

Thanks to $100+ crude oil, easy access to junk bond markets, and fracking technology, US shale flooded the market with supply at an unprecedented scale. In the past, crude oil supply moved at a glacial pace as large extraction projects took time to assess, finance, and develop. Once fracking technology became widespread, nimbler US firms became the new ‘swing producers’. Unlike producers from the past, US firms can ramp production up and down much more quickly and are thus much more responsive to changes in the market. In short, OPEC finally met its match.

Following the 2014 and 2015 crude oil bear market, many US producers went bankrupt after failing to generate cash flows and losing access to financing. As fracking technology improved over time (lowering breakeven prices necessary to operate profitably), many had predicted another resurgence for US producers in 2017. However, this prediction failed to materialize given a variety of reasons including poor weather and infrastructure bottlenecks. While US supply has been positive following the second quarter of 2017, growth rates today remain subdued. The bull market in crude is thus intact.
