Economy in Brief: April 2024

Global inflation trends have been in concert for major money center countries/areas- excluding Japan, of course. Inflation flared after Covid struck and in the wake of the Russian invasion of Ukraine. It continued to ramp up more than central bankers thought. Interest rates were raised from very low levels- the U.S. led the pack in terms of rate hike speed, getting its key rate up to its prevailing inflation rate in record time after a long period of being asleep at the switch. It said it stood prepared to hold rates ‘higher longer.’ Then the next unexpected thing happened; inflation fell sooner and more sharply than expected and it did this globally, not just in the U.S. However, we are now into phase three of this process: inflation went up more and longer, inflation then fell more and faster and now inflation is off peak but not back were we want it—and it is looking stubborn. This is more or less a global money center country/area description of inflation. Inflation that went through its boom-bust phase, as you clearly see from the sequential growth rates of the German PPI is now up from its lows. The headline price level is falling but losing momentum. The core PPI is only falling in its ‘legacy’ 12-month rate.

German PPI inflation falls by 2.8% over 12 months, falls at a 3.4% annual rate over six months, and falls at a 1.2% rate over three months. Core PPI inflation falls by 0.7% over 12, months then rises at a 0.7% annual rate over six months and three months. The core points the way for trend.

The NSA (not seasonally adjusted) sequential data show acceleration across and three major PPI sectors: consumer goods, investment goods and intermediate goods. Prices only fall over 12 months for intermediate goods. All other sectors trends show increases by period and all show acceleration in progress.

German CPI data show higher inflation over three months than over 12 months for the headline and the core with a dip in between – not a steady state acceleration but a clear hint at where things are headed and with German inflation rates clearly above the EMU-wide 2% mark.

Registrations for cars in Europe for March fell by 8.8% month-to-month after falling by 1% in February. January, however, had been a strong month for registrations in Europe. The sequential trends are mixed and do not show a clear way forward. The 12-month change in sales/registrations falls 4.7%. Over six months registrations fall harder at an 11.9% annual rate, but then over three months registrations gain at a 7% annual rate. These data are prone to volatility. To adjust for that, I execute the same calculations on three-month average data to smooth out the volatility and let the trend shine through. Unfortunately, this procedure still does not produce a clearer picture of trend.

Chart 1, executed on year-over-year growth rates, shows registrations gradually losing momentum among reporting countries. Sequential growth rates across countries finds Germany and Spain with accelerating sales/registrations. France and Itay with fairly clear trends showing decelerating sales. Meanwhile, the U.K. trend shows confusion with no clear pattern emerging.

Looking very broadly, all reporting countries show registrations lower in March everywhere except for France, in 2024 compared to January 2020 before Covid struck. France is the lone exception that shows registrations in March higher by just 2.2% than they were over four years ago. That is not exactly a stunning success.

When the Music Stopped, or at Least the Inflation Progress... U.K. inflation on the HICP measure eased to 0.4% in March from 0.5% in February. The month-to-month CPIH measure also rose by 0.4% from 0.5% in February. The CPIH excluding food, energy, alcohol, and tobacco rose by 0.4%, the same as in February. The Bank of England looks at several inflation gauges; it targets HICP, which rose 3.2% year-over-year in March and slowed slightly from its year-over-year pace of 3.4% a month ago. The HICP steps inflation down to 2.7% over six months but then inflation rises at a 3.9% annual rate over three months, not what the Bank of England was looking or hoping for. The CPIH is 3.7% year-over-year, down to 3.3% at an annual rate over six months and up to an even worse 4.4% over three months. The core CPIH that excludes food, energy, alcohol, and tobacco, pretty much all things necessary or fun in life, rose by 4.7% over 12 months, cooled to 3.7% over six months, but then ticked up to 3.8% at an annual rate over three months.

Inflation makes progress, but not reliably enough The bottom line is that inflation, as represented by either six-month or three-month inflation rates, is generally lower than it was over 12 months ago, indicating ongoing progress on the inflation front. However, the progress isn't as substantial as the Bank of England would like to see; there's some backtracking over three months compared to six months that's not what monetary policy is looking for to gain confidence that inflation will continue to fall toward target.

Diffusion results are mixed Sequential diffusion- Diffusion calculations applied to the categories in the table showed an inflation over 12 months that exhibits diffusion of 23% compared to inflation rates of 12-months ago. The diffusion measure is the percentage of categories where inflation is accelerating period-to-period. Over six months, diffusion falls to 7.7%. HICP inflation on that comparison fell to 2.7% from 3.2%. The diffusion calculation comes from comparing the inflation rate in each category over six months to the same category over 12 months. If the inflation rate is higher over six months than over 12 months, we count it as acceleration. Acceleration was quite rare over six months, occurring only for housing and household expenditures. However, over three months with the HICP rising to 3.9% compared to 2.7% over six months, diffusion jumped from 7.7% to 61.5%. Being above 50% is critical because it means inflation is accelerating in more categories than it is decelerating and that tends to add more authenticity to the acceleration of inflation over three months. It tells us that the acceleration was not just because of a few rogue categories or several large increases in categories that had a high weight, but rather it's something that's broad-based.

Monthly diffusion- Monthly data are more lenient on the diffusion front. In March diffusion is only 38.5% with the month-to-month gain of 0.4%, below a 0.5% rise in February. Inflation is accelerating in March in only 38.5% of the categories. However, in February inflation rose 0.5% compared to 0.1% in January and inflation accelerated in 61.5% of the categories, clearly over half of them. In January with that low inflation print of 0.1%, inflation accelerated in only 30.8% of the categories. Over the last three months, the diffusion data were quite good for two months and moderately bad for one of them. However, when we go back to the table to look at the three-month changes compared to six-month changes, the BOE has that high 61.5% diffusion number staring us in the face.
