OPEC countries are prepared to step in to alleviate any market shortages together with other producers, the group suggested on May 14, acknowledging recent geopolitical developments could hit oil supplies.

“Despite the large uncertainties prevailing in key market fundamentals, OPEC, as always, stands ready to support oil market stability, together with non-OPEC oil-producing nations,” OPEC said in its monthly oil market report.

The U.S.’s withdrawal from the Iran nuclear deal and the reimpostion of sanctions against its economy is expected to hit the OPEC country’s oil exports while Venezuelan supply is taking a hit after economic and political crises impact its energy industry.
