Rising labour costs have only the smallest impact on services inflation
As the inflation episode starts to abate, central bank governors have been keen to advance narratives to justify why they would continue hiking interest rates, especially when it is pretty obvious that the drivers of the inflation were mostly coming from the supply-side and suppressing aggregate spending (via the higher rates) would not be a very effective measure to deploy. This is quite apart from the debate as to the effectiveness of using interest rates to stifle spending, which is a separate discussion with no clear conclusion other than probably not. As I have noted previously, it was hard to argue that inflation was accelerating out of control when it had started to decline many months ago. So they had to come up with a different narrative – which was that while inflation was falling it was not falling quickly enough. That is the current story line the officials trot out. And that allows them to claim that if it doesn’t fall quickly then two things will be likely: (a) workers will build the higher inflation into their wage demands and set off a wage-price spiral that becomes self-fulfilling even after the supply-side factors (Covid, Ukraine, OPEC) abate, and (b) that people would start to expect higher inflation was the norm and build that into the contractual arrangements and pricing. Neither behavioural phenomenon has shown any sign of becoming entrenched, which leaves the central bank officials without a cover. And even research from central banks themselves is demonstrating that there is not ‘high inflation’ mindset taking over.
