So I'm a total newbie when it comes to commodities and global markets, so please feel free to tell me if I'm just being very stupid, but here's my view on the oil situation.
To me, oil seems like a brilliant investment at the moment. Saudi is now basically unable to artificially reduce the price of oil any further via their oil output. They've pretty much tried that, no holds barred, in an attempt to suffocate US oil production but have fallen far short of that (thus, I assume, statements like the one you posted, in the hope of scaring the market and driving it down further). US output looks pretty resilient and prices look like they will need to stay severely depressed (below $60) for a sustained period in order to substantially dent US output. The vast majority of US oil has a break even price of $50 or lower.
Now the Saudi's are in a bit of a pickle. Even with disappointing growth in emerging markets and low global demand, prices don't look likely to plunge below $60, leaving the US market mostly unscathed (even if some investment might be delayed). The low of $58(ish) was reached at a time of panic and I imagine speculators waiting for it to bottom out.
At some point Saudi will have to recognise that they don't have enough clout to suffocate US oil output and will then likely re-adjust their output back down to avoid the market becoming massively oversupplied for a long period of time.
There's already a growing consensus that oil will end 2015 above $70 and there aren't many substantial catalysts left that could put downward pressure on the price (increased output, disappointing growth, speculator panic have all been 'used up' already), short of another full-scale global economic slowdown.
Tl;dr: Even with many strong downward pressures, oil has refused to fall well below $60. OPEC will want to address market imbalance soon. Price can only really go up. Views?
