First-quarter earnings have been a slippery slope for big oil companies thus far as geopolitical challenges and receding prices may be putting the clamps on profitability for the rest of 2019.

Venezuela sanctions as well as production cuts in Canada have affected the profit margins for companies, such as industry giants Exxon and Chevron. Exxon said earnings showed a loss of $256 million in the first quarter and net income dropped to $2.35 billion, which represents its lowest in the last three years.

“It was a tough market environment for us this quarter,” said Exxon Senior Vice President Jack Williams, who oversees the company’s refining and chemicals businesses. “The margins were at historically low levels.”

Of course, the latest drop in earnings doesn’t mean big oil is hurting in any way.

“They’re still making money, but the fat margins have disappeared,” said Sandy Fielden, director of oil research for Morningstar Inc.
