Wall Street stocks resumed their upward climb Wednesday, while oil prices dropped with traders interpreting a delay to an OPEC+ summit as a sign of possible discord.

A statement announcing a delay to 30 November of a planned summit of the 13-member OPEC group led by Saudi Arabia and their 10 partners led by Russia did not provide any explanation. 

The oil exporters are due to decide on their output policy amid slumping crude prices and weak crude demand as China's post-Covid rebound stutters and Europe and the United States confront slowing economies.

The current output strategy by OPEC+ that saw nine members led by Riyadh cut production to boost prices has failed to bring about lasting recovery.

Oil prices initially tumbled following the announcement of the delay, but finished the day only modestly lower.

"The delay of the meeting has sent prices lower because it increases the risk of the Saudis removing their additional voluntary cuts to the tune of one million barrels per day that has been in place since July," said City Index and FOREX.com analyst Fawad Razaqzada. 

Some analysts have pointed to possible discord between top oil exporter Saudi Arabia — which has pushed for production cuts to support prices — and Russia.
