Why the oil price means bubble trouble

There are plenty of explanations for what’s happening in the global oil markets. It’s caused by the economic boom in the world’s largest developing countries, particularly China and India. It’s caused by the unwillingness of the oil cartel Opec to pump more crude. It’s caused by the fact that the world has reached peak oil – the moment in our history where supplies of the black stuff start to dwindle.
All of these factors may have contributed to the upward trend in the oil price over the past six years, which has seen the cost of a barrel of crude rise from around $20 a barrel to $135 a barrel today. None of them really explain, however, why the price should have gone up by more than $5 in the past 24 hours and by a third in little more than a month. That sort of price action is the result of a speculative frenzy of the sort that was witnessed in the dotcom mania of the late 1990s. The oil market, to put it simply, is a massive bubble waiting to be popped.
