Prior to Friday, crude prices had been climbing as traders harbored concerns of supply disruptions in the Middle East and Venezuela that could tighten the global oil market.
The U.S. earlier this month pulled out of the Iran nuclear deal, renewing sanctions on the country, which the third largest producer among the Organization of the Petroleum Exporting Countries, or OPEC. Sanctions on Iran could limit its ability to export crude oil, leading to further supply shortages.
Simultaneously, fellow OPEC member country Venezuela has continued to undergo extreme economic collapse, putting the country's crude supply in jeopardy.
Given the potential supply disruptions, there is a "real possibility" of oil reaching $100 per barrel, according to Jefferies energy analyst Jason Gammel.
"It is really going to be primarily dependent on whether all of the supply risks that appear to be emerging all come together at the same time," Gammel told Bloomberg.
