Oil and natural gas ETF prices continue to drop, but that could be about to change, according to an article on the Wall St Sector Selector.

Increased volatility in the oil market due to growing tension between the United States and Iran could push oil ETFs if the Obama administration sanctions Iran, according to John Nyaradi, editor of Wall St Sector Selector.

The TransCanada Keystone XL Oil Pipeline Project is another factor affecting oil prices. If the project takes off, oil supplies will open up to the U.S., thus increasing oil prices, the article said. But the project should take two years to come to be completed, according to the article.

Finally, the European debt crisis also is playing a role in oil and natural gas ETF prices. If the debt issue remains unsolved and leads to a global recession, it will lead to lower energy prices due to lower energy consumption, according to the article.
