Most energy commodities strengthened week-on-week on the back of the minor gains in oil and the rising equities. Despite the positive tone in global stock indices, oil prices only gained a meagre 0.8% last week on the back of a weaker dollar and mixed indications from the US inventories data. Coal prices also moved up marginally, driven by the stronger energy complex and higher freight rates. Carbon prices returned to track the key energy contracts and closed 1.5% higher, after spending the past two weeks racking over the uncertainties of an industrial length due an EU court ruling. North European gas prices were fairly volatile last week, driven by the variation in consumption and supplies. Strong flows through the IUK exports helped eased the continental demand whilst balancing the length in the UK system. Gas forward contracts ticked up echoing gains in the prompt and oil market. Spot power prices were bullish last week on reduced wind and nuclear availability, while forward contracts also moved up amid tightness in the short-term market and positive sentiment from the primary fuels.
