Are Natural Gas Prices Predictable?

ENERGY MARKETS ARE UNPREDICTABLE

The supply and demand equation is extremely complex. The number of variables is very high and the interactions between them are not simple causal relationships. Most forecasting models are based on mathematic wizardry that unveils correlations. However, analysis shows that these correlations change over time, so a current correlation cannot be used to predict the future. Moreover, even if a correlation would be constant, e.g. between the price of electricity and natural gas, this knowledge doesn’t help you very much. It just tells you that one unknown factor (the future electricity price) is correlated to another unknown factor (the future gas price).

On top of this, international energy markets can be shaken by unexpected events. Some of those noticed in the recent past: the shutdown of nuclear power stations in France due to security issues, the impact on worldwide energy markets of the Fukushima nuclear disaster or the shale gas revolution in the US. Anyone claiming that she/he can predict energy markets, is claiming that she/he can predict such events.

Best case, forecasts are right 50% of the time. Therefore, they are not a solid basis for making your pricing decision.   And if your energy buyer believes in forecasting, she or he is a danger to the financial health of your company. One day, she or he will take a decision based on a wrong forecast that makes your company buy energy on the wrong side of the market.
