KEY POINTS • Four sources familiar with OPEC+ discussions told Reuters that additional production cuts were being discussed among options for Sunday’s session. • Three out of four sources said cuts could amount to 1 million bpd on top of existing cuts of 2 million bpd and voluntary cuts of 1.6 million bpd, announced in a surprise move in April and which took effect in May. • OPEC+ pumps around 40% of the world’s crude, meaning its policy decisions can have a major impact on oil prices.
