It's worth a comment on oil prices which have been collapsing with remarkable speed lately. Firstly, let's briefly recap the price history of the last five years, which I have divided into eight eras in the chart above.
So whither these trends now? On the one hand, it seems clear that the recent downward forces on prices will continue: negotiations with Iran will drag on as the US administration is determined to postpone any attack till after the election, while Iran is determined to not give any more ground than it absolutely has to. Similarly, Spain's difficulties rescuing Bankia, and the fact that there are likely still a lot of not-fully-discounted bad loans in Spain's banks, suggest that the Spanish government is near the end of its rope. Meanwhile the tension between the Greek populace and international authorities is not resolved at all. Eurozone leaders at present still appear to have no serious strategy for addressing the problems. Spanish and Greek unemployment continue to soar. And then there is the continued inability of the polarized US political system to come to grips with major challenges - particularly the upcoming expiry of the Bush tax cuts and the automatic spending cuts that will be triggered around the end of this year. All this is chilling stock markets everywhere, particularly as no-one really knows what the implications for the global financial system will be if pieces start to fall off the Eurozone as it trundles forward.
These kinds of considerations suggest that the downward break in oil prices could continue quite a lot further.
On the other hand, with Brent falling below $100, we are now testing the current level of OPEC's tolerance for lower prices. In 2009/2010 they were willing to settle for $70ish without reducing production. However, since that time they - particularly Saudi Arabia - have signed up for extensive domestic stimulus programs to appease the population following the Arab Spring. Thus they almost certainly need somewhat higher prices now. Mr Al-Naimi has been quoted on numerous occasions in the last year saying that $100 was a fair price for oil. Will they cut oil production now, on that rule? Or wait till it crosses $90 or $80? I'd be surprised if it took $80 to get them to act.
Thus I would expect that if the downward movement were to continue, it would not be too much longer before it would trigger a Saudi production cut. There is some possibility (as in 2008) that prices could transiently go lower particularly if events in Europe turn truly dramatic and markets start to panic. Then it takes a while for the effects of production cuts to work through the system. But then again, I would expect market participants to have learnt something from what happened in 2008 and be more prone to price in the effect of OPEC production cuts in advance.
Further, once we are below $100 in Brent prices, there is considerable risk of upward surprises. A breakdown in the Iran talks, European authorities doing something relatively functional, Greek elections producing a pro-agreement coalition, hiccups of any kind in the global oil production system. In the long term, I think oil prices are certainly going to average over $100.
In short, while prices could certainly go lower in the near term, they are at levels were, if I were an oil trader, I'd feel more comfortable being long than short unless my time-horizon was very short. If one were sitting in cash, there could be an argument for waiting a little longer before jumping in on the long side - at least while the situation in Spain seems quite so unresolved.
