Natural gas and the US dollar in the short-term
In the past four trading sessions, natural gas futures and the US Dollar Index moved in opposite directions three out of four times. The correlation between the two over the past four trading sessions was -56.6%. There was an inverse quantitative relationship between them during that short period.
When the dollar falls, it makes commodities cheaper for importing countries, which boosts prices. In the past, US natural gas wasn’t exported in large quantities outside North America. Historically, there wasn’t a relationship between natural gas and the dollar.
In February 2016, the US started exporting natural gas in the form of liquefied natural gas from the lower 48 states to outside North America.
Natural gas and the US dollar in the long-term
On March 3, 2016, natural gas futures closed at $1.64 per million British thermal units—a 17-year low. From March 3, 2016, to January 18, 2017, natural gas active futures rose ~101.3%, while the US Dollar Index rose 3.4%. During that period, the US Dollar Index and natural gas prices moved in opposite directions based on the closing prices in 122 of 222 trading sessions. The correlation was -11.2% during that period. It shows the lack of a relationship between the two over a longer period. So, other factors, like the weather, were driving movements in natural gas.
Natural gas and Donald Trump
Donald Trump’s aggressive energy policy could lead to higher natural gas production. It could boost natural gas exports. His policies could also mean the return of coal as a source of fuel for power generators. It would make even more gas available for exports.
So, as US natural gas becomes a more international commodity, prices could develop a relationship with the US Dollar Index that’s similar to the relationship between crude oil and the US Dollar Index.
