Summary
Humanity has reached a significant demographic milestone, falling below the replacement fertility rate for the first time in history, according to a recent paper titled "Terra Incognita: The Economics of a Shrinking World." This trend raises critical questions about the future of economic growth and investment strategies, particularly as the global population is projected to peak at around 9 billion by 2056 before entering a decline. The implications for investors are profound, as traditional assumptions about market growth and asset valuations may no longer hold true in a low-growth environment.
The paper highlights that many countries, including China, are already experiencing negative fertility trends, with 219 out of 236 countries studied showing declines since 1950. This shift challenges the long-standing belief that poorer nations will naturally have higher birth rates as they develop. Instead, factors such as education, urbanization, and changing societal norms are contributing to lower fertility rates across various income levels. The authors argue that the demographic changes could lead to a significant slowdown in economic growth, as fewer workers may result in reduced productivity and innovation.
As the discussion unfolds, the hosts explore the potential economic consequences of a shrinking population, including the impact on gross domestic product (GDP) and asset returns. They note that while GDP can grow through increased productivity or a larger workforce, a declining population could hinder both avenues. The conversation also touches on the historical context of population decline, drawing parallels with the economic aftermath of the Black Death, which resulted in higher wages for survivors but also significant societal upheaval.
In conclusion, the demographic challenges posed by falling fertility rates and an aging population may lead to a fundamental shift in economic dynamics, prompting investors to reconsider their strategies in a world where growth is no longer guaranteed.

A Swiss government bond pays half a percent a year. A British one pays more than five. Easy choice, you'd think. But yields can cut both ways. A low yield can mean the world trusts you with its money, or that your economy has stagnated. And high yields can be a sign of a strong economy, or that bond investors are getting nervous. So, low yields or high ones, which would you rather live with? --- Thank you to Trading 212 for sponsoring this episode. Claim free fractional shares worth up to £100.
