Can we pull off a soft landing?

Central bank hiking cycles in the developed world are slowly but surely coming to an end, raising the question of whether they have pulled off a soft landing, defined as a fall in inflation back towards target of around 2% without a meaningful decline in output and rising unemployment. On the face of it, the answer to this question is a resounding no. Interest rates in Europe, the UK and the US are up anywhere from 300 to 450bp in less than a year, driving up bond yields , and pushing yield curve inversions to near record levels. Anyone using these data points to predict what comes next, using historical relationships, will conclude that the wheels are about to come off in developed economies and their financials markets alike. The difficulties in the US regional banking sector is, in this case, simply a canary in the coal mine, warning of bigger shocks to come. The investment implications of such a view are simple; short equities and long short-term government bonds.

China's Population

Last week we learned that China’s population shrunk last year, for the first time in 60 years, by 850K, the net result of 9.6M live births, and 10.4M deaths. It is worth taking these numbers with a pinch of salt. Accurately accounting for some 1.4B people is difficult, especially down to a sub-1M difference between deaths and births. It’s possible that future revisions will show that China’s population has been shrinking since the beginning of the 2020s, or that it won’t start shrinking until 2025 or beyond. What is clear for anyone with even cursory knowledge of Chinese demographics, however, is that this headline was coming sooner rather than later. China’s fertility rate has long since declined below the replacement level, and all-age mortality is now rising as the population ages. But does it matter that China’s population is now shrinking?

The Quantum Effect of Fertility

Whether you’re an evolutionary biologist, cultural sociologist or a neoclassical economist, the study of human fertility behaviour can be boiled down to an interplay between two immovable forces: the quantum and tempo effect. The first treats the fundamental question of reproduction; how many children to have, and how much resources to invest in each of them. In its simplest form, the quantum effect is the study of how much, if at all, women exert control over the quantity of offspring they produce. The extent to which they do—and almost all disciplines agree that they do in most social contexts—the analysis focuses on the conditions that determine the number of children, and how much resources that are devoted to each of them. It is an analysis of trade-offs, concentrated on the trade-off between the quantity and quality of offspring. How this balance is achieved represents one of the most crucial processes in the study of reproduction, aggregate fertility, and the demographic transition.

Back to the (Macro) Basics

"Where are we in the business cycle?" is a question macroeconomists often are asked by investors. On the face of it, it is a reasonable question. The macroeconomic backdrop is an important input variable for key asset allocation decisions such as whether to be over- or underweight stocks relative to bonds, sector rotation, not to mention FX and credit positions. The question invites the idea that economic expansions are on the clock. They are in the sense that their average length is a question of a relatively simple empirical exercise. But a classic truism still remains. "Economic expansions don't die of old age, they're killed by economic policy", a phrase I have adapted from the U.S. version ending with the idea that economic expansions usually are killed by the Fed.
