The oil market is nervous, which seems likely to lead to volatility. The surprise is that sharp moves may trend to the upside rather than the downside. The two big concerns are about how sanctions on Iran may crimp output, as well as how OPEC lacks spare capacity to boost output. Such concerns are a stark change from the attitude that accompanied the sharp price falls in recent weeks, when supply seemed to be expanding strongly.

FINSUM: The Saudis are saying they will expand production to a record, but the reality is they do not want to do so because they don’t want prices to fall. It seems like OPEC will walk a line to keep prices where they are.
