This Chart Compares the Oil Price History to Natural Gas Price History

The past year has delivered one of the worst crashes in oil price history. WTI oil prices have plummeted 41% since July 2014.

It has been the worst-performing commodity in the energy sector, with prices slumping even lower than natural gas.

oil price historyNatural gas prices have tumbled 31.9% over the same period. The energy sector hasn't been this beaten down since the 2008 financial crisis.

In the chart to the right, you can see how the oil price history mirrored the natural gas price history during the recession.

Both commodities saw a bubble-bursting sell-off in 2008. This was due to President Bush's lifted drilling ban and the Lehman Brothers bankruptcy, among many other causes of the financial crisis. WTI oil and natural gas respectively dropped 78.1% and 57% from July to December that year.

The price spread between oil and natural gas is important because of the amount of energy both commodities provide. You see, natural gas consumers get a lot more bang for their buck...

Why There's a Spread Between the Oil Price History and Natural Gas Price History

A report by CME Group Inc. (NasdaqCME) last year said $1 worth of natural gas - at a price of $5 per million British thermal units (BTUs) - can obtain 200,000 units of energy. Conversely, $1 worth of WTI oil - at a price of $97 a barrel - can only obtain roughly 60,000 units. That's a 330% energy content price gap.

The price disparity stems from how both are traded. Because oil is transported in liquid form, it enjoys high demand and high prices. That liquid form also makes it easier to transport, and it's the No. 1 traded energy commodity in the world. However, because it is easily transported, its prices are exposed to geopolitical factors that can disrupt transports at any time.

Although natural gas is energy efficient, it can't be globally transported due to its physical gaseous state. That's why natural gas prices are lower and less volatile than oil prices.

But the limits of the natural gas trade are about to be removed. The United States will begin exporting liquefied natural gas (LNG) by the end of 2015 and will account for 6% to 8% of the global LNG market by 2020. This will spike worldwide demand in natural gas, providing more room for prices to soar moving forward.
