More on Goldman Sachs oil call - prices $70-$80 and volatile in short term

I posted on GS and oil earlier:

• Oil- Goldman Sachs see Brent retesting $80 late this year rather than summer

Reuters have a bit more detail up now:

• Goldman Sachs expects volatile oil prices in the short-term
• on the back of uncertainty over possible disruptions to supply
• expect benchmark Brent crude in a $70-80 per barrel range

"Production disruptions and large supply shifts driven by U.S. political decisions are the drivers of this new fundamental volatility, with demand remaining robust so far"
