Interesting piece in the FT today about the dramatic move of the WTI curve from contango into backwardation in recent days:

for the first time since the start of the global financial crisis in September 2008 the cost of WTI crude for immediate delivery is higher than forward contracts.

The downward slope of the price curve is known in the industry’s jargon as “backwardation” and signals a tight supply and demand balance, while the opposite condition, which has prevailed for more than three years, is known as “contango”.

The speed and magnitude of the shift into backwardation has left the oil market reeling.

...and it goes on to conclude that physical oil traders have got it right - and stocks really ARE tight! ....US commercial stocks of crude oil are nearly 8% below year-ago levels at 333mn bbls - which is a fair-sized move in the context of history and the supplies needed to keep the supply system running (which are generally thought to be 270-280mn bbls.....so the fall in stocks over the last year has trimmed the stocks buffer vs "system need" by around 35% - from c.100mn bbls)

It is worth considering which of the scenarios postulated at the end of that article are the most likely to be the underlying cause of this price move.  Is the market expecting future oil demand to fall? Possibly, but there hasn't been any sharp change on the outlook there! Will future production rise? Again this is possible - and perhaps one might argue that Gaddafi's death is likely to make Libya better able to draw a line under recent events and move forward, restoring oil supplies.

But the other scenario is that headline (flat) prices move sharply higher.....

Of course, if that were to happen then I'd guess another SPR release may be on the cards - but perhaps the US may not rush to do that this time.....because the weekend news that the heir to the Saudi throne had died may well have been the main cause of the move into backwardation? As the Telegraph puts it:

The likely decision to appoint a hardline conservative prince as heir apparent to the throne of Saudi Arabia could cause a popular backlash against the rulers…
