Saudi Arabia's crude oil production fell to its lowest level since 1990 in August, driven by attacks on the kingdom's energy infrastructure and export routes stemming from the ongoing conflict with Iran.

Riyadh reported to OPEC that production declined 1.9 million barrels a day to reach 6.238 million barrels a day in August, according to Bloomberg. That figure is lower than a previous wartime low reached in April, which was itself the lowest production level the kingdom had reported since the start of the Gulf War.
