A few months ago, this blog commented that a rise in inflation in the advanced economies early in 2016 was “almost certain”. Thank goodness for the word “almost”. Since then, oil prices have plumbed new depths, and the markets have remained obsessed with fears about deflation.

The case for higher inflation in 2016 rested on the fact that the impact of energy on headline consumer price inflation would change direction when oil prices stabilised. This “inevitable” arithmetic effect has been delayed by the slump in oil prices in January, but it should manifest itself in the near future.

The key question, though, is whether this automatic rise in headline inflation presages a more important turning point for underlying inflation in the advanced economies – a turning point that has been wrongly predicted for several years now.
