Brent crude oil prices hiked to US$76-US$77 per barrel, and estimating a geopolitical risk premium of about US$10 per barrel, Goldman Sachs released a research report saying. Although Goldman Sachs' base scenario is that Brent crude oil will fall to around US$60 per barrel in 4Q25 assuming no supply disruptions, the broker also considered a scenario of reduced Iranian supply, forecasting that Brent crude oil prices could surge slightly above US$90 per barrel. This premium seems reasonable in the tail risk scenario where regional oil production or transportation is negatively impacted.Related NewsM Stanley Expects PETROCHINA (00857.HK) Shr Price to Rise w/ TP/ Rating at $8.75/ Overweight
