Discussion and Analysis by Charles Porter:
Bank of England: Stop and Think – Please!
Inflation within the United Kingdom is uncontrolled and rampant, surely, we have to raise interest rates! At least that’s what the first page of an economics textbook might suggest. In reality, a decision to tighten UK monetary policy on November 2nd could be extremely harmful to both the real economy and the Brexit negotiation period. The jibe above is not to suggest that Dr. Mark Carney is not a learned and intelligent man; by contrast, his successes at the Bank and, for that matter, throughout his career, have been commendable. Suggesting an imminent interest rate hike, however, seems foolish.
The Bank of England is not an extraordinary central bank. It too shares a mandate to control price inflation in the economy. Of course, as the economy overheats and inflation ensues, an increase in the rate of interest encourages saving over consumption, thereby cooling down the inflated economy. With year-on-year CPI inflation registering at 3.0%, according to ONS data released on Monday, the UK is unequivocally a price-inflated economy.
However, there is no domestic inflationary pressure. The rise in the overall price level is almost exclusively driven by an exogenous factor: the exchange rate. The Brexit result from the June 23rd referendum has seen sterling lose approximately 15% of its value, event to date, against the Euro. This has caused a delayed effect of import price inflation, and, therefore, general price inflation that grips the economy whilst reserves and stock are depleted and refreshed at inflated rates.
Therefore, domestic inflationary pressure may no longer be measured by the overall level of price inflation within the UK economy. Instead, by turning to the components of the CPI basket, degrees of exchange rate sensitivity can be isolated to understanding the UK economy. Presented below is overall inflation against food inflation and services inflation. Food inflation, is a basket component that is highly dependent upon importation and, therefore, the deterioration of Sterling’s value. Services trade, by contrast, is less determined by the rate of exchange and the market comprises of a higher propensity for domestic consumption and production.
If there were no domestic inflationary pressure outside of exogenous exchange rate price inflation then total inflation should be explicable by, for example, food inflation alone without a significant correlation to services inflation. Indicatively, above, we can see that this hypothesis is verified. The differential within food CPI inflation, measured by the right-hand axis, is far more significant than steady services inflation. Moreover, the adjusted scale seems to represent a good co-movement of food inflation with overall inflation.
In this second part of this article, we analyse the underlying relationship between the components of inflation and analyse Bank of England monetary policy in light of these result. The conclusion reveals that a Bank of England rate hike next week could be foolish.
US Trade War Tariffs With all markets awaiting what emanates from POTUS later today, Trump has certainly achieved one aim: getting the world’s collective attention. Increasingly desperate TV pundits have spent the past hours dragging past Trade Negotiators into the studio in an effort to get them to predict what the tariffs will look like. […]
De-Dollarization A shift away from the US Dollar with Central Bank Reserves denominated in US Dollars moving down from a high of just over 70% down to 60% in the past 20 years is note worthy but the speed of that decline makes it less striking. However there are 3 factors that are changing the […]
Pairs Trading Back in the days when I worked in Bermuda for a hedge fund, we were always seeking stocks that were overvalued and other stocks that were undervalued having analysed both sets of historical price behaviours. Normally those stocks were in the same industry but not necessarily in the same geographic region. In the […]
