Conventional wisdom says investors ought to worry about rising oil prices. But history says this isn't necessarily bad news for the markets ...

If you’ve been suffering from sticker shock at the pump lately, you’re not alone. Nationally, there’s been a sixty-cent-a-gallon increase in gas prices, on average, over the past year.

That’s in large part because the price of a barrel of crude oil has risen from about $45 a barrel to more than $70 during that time. Some of it can be attributed to the relative health of the global economy, which is boosting demand. At the same time, though, there have been supply issues.

For instance, there have been production disruptions in Venezuela, which has been enmeshed in political and economic turmoil. There’s also the U.S.’s decision to exit the Iran nuclear deal and threatening sanctions against countries that do trade with Iran, the third biggest oil producer in OPEC (Organization of the Petroleum Exporting Countries). And there are other, more localized hiccups, which combined have helped raise prices to the point where President Trump has urged Saudi Arabia to increase production. Saudi Arabia, despite Trump’s proclamations, has yet to agree to do so.
