SUMMARY
- Non-energy goods prices have risen steadily over the past six to nine months, while service sector inflation has been more benign. Some might argue that without a pickup in service sector inflation, the bank could face an undershoot of the 2% inflation target in two to three years’ time.
- A cyclical (short-term) rise in productivity is possible, based on the view that productivity improves as resources become scarce, but a secular (longer-term) return to 2% productivity growth does not appear likely.
- Assuming that the Brexit negotiations do not heavily disrupt the UK economy and that underlying momentum continues to tighten labor market conditions, we would expect to see some modest upward drift in wages as the pool of workers shrinks and employees feel more confident about asking for a raise. This in turn could lead to a rise in domestically generated inflation over the next few years.
In its recent quarterly inflation report, the Bank of England gave the market some fascinating insights into the challenges it will face in setting appropriate monetary policy over the coming years. In particular, the bank will need to weigh the risk posed by the current period of above-target inflation against the medium-term challenge of maintaining inflation at the 2% target.
Too much or too little?
Given the current above-target inflation and better-than-expected GDP growth, the report’s primary focus (not unreasonably) was on how much inflation overshoot the bank is willing to accept and how quickly it expects inflation to move back toward the 2% target. We would agree with the bank’s forecasts that Consumer Price Index (CPI) inflation will rise toward 3% by the end of the year before slowly drifting back toward 2% over 2018 and 2019. Similarly, the bank expects UK GDP growth to weather the Brexit-related uncertainty and average 1.75% over the next two to three years, which should support a narrowing of the output gap and thus medium-term wage growth and domestic prices.
However, as we look two to three years out, is inflation risk still skewed to above-target prints, or will the UK (like many other developed markets) instead find itself with the challenge of below-target inflation? As my colleague Tiffany Wilding pointed out in a recent PIMCO Blog post, even the U.S. economy looks on track to undershoot its inflation target, despite continued improvement in employment growth and historically low unemployment. Similarly, Europe and Japan are exhibiting very benign underlying inflationary pressures despite historically low measures of unemployment. Can the UK buck this trend over the medium term, or will it succumb to the same global forces? And what are the implications for UK monetary policy, and for asset prices more broadly?
Starting with the here and now, the Bank of England’s assessment is that the current rise in inflation can be explained by the pass-through effect on import prices of the 10% drop in the pound sterling following the Brexit vote last June. One way to look at this is to separate the rate of inflation in non-energy goods prices, which tends to be correlated with import prices, from service sector inflation, which tends to be more reflective of domestic price pressures (see Figure 1).
Already the picture becomes much clearer. While prices for non-energy goods have risen steadily over the past six to nine months, price movements in the service sector have been much more benign. With the exception of some volatility around the Easter holiday in April, service sector inflation has remained steady between 2% and 3%. This would certainly support the view that there is little sign of any secondary effects putting sequential upward pressure on the inflation rate. Indeed, one might argue that without some pickup in service sector inflation, the challenge facing the bank in two to three years’ time could be a potential undershoot of the 2% level.
