RE: "Goldman says a Biden win could be a ‘positive catalyst’ for oil prices"9 Nov 2020 10:58
The significant Oil Price drop of Q4 2014 onwards (and the subsequent underinvestment in Exploration since) was only as a direct result of the massive increase in US Shale production, Iran at it's peak was producing 3.9M bpd of which more than 2M bpd is used for home energy consumption. Even if Iran production/exports are allowed to return to global markets post a renewed JCPOA by Biden administration (and that's a big if with Trump administrations recently imposed obstacles in place, and Iran elections not until another 8 months which will likely prevent any potential negotiations in H1 2021), Iran's underinvested aging fields can at first only provide few hundred thousand additional bpd (and likely only from 2022 onward), whereas as GS this time smartly stated "A Biden administration could provide a further boost to oil prices by making production — especially for shale — more expensive and more regulated".
Hence, any eventual additional barrels coming out of Iran (2022 onward) will by far be outweighed by potential drops in US Shale Production, IMOO, DYOR.
