Energy commodities apart from natural gas were sharply lower on Monday amid global demand uncertainties. Moody's outlook cuts as well as further contraction of Spain's GDP in Q2 dented energy demand prospects.
Crude oil prolonged its slump as investors were worried about Eurozone's fiscal difficulties. Market participants also awaited US crude oil inventories data due on Wednesday. Inventories are expected to remain flat.
Brent oil declined as demand concerns outweighed supply worries. Tensions between Iran and world's major economies coupled with turmoil in Syria limited the downswing.
Natural gas was the only gainer, approaching seven-month high amid abnormally hot weather forecasts in the US.
Heating oil moved in tandem with Brent and crude oil ahead of the US supplies data. Rally of the US Dollar also weighted down on the commodity.
