Abstract

With recourse to archival, printed primary, and secondary sources, this paper reconstructs global real interest rates on an annual basis going back to the 14th century, covering 78% of advanced economy GDP over time. I show that across successive monetary and fiscal regimes, and a variety of asset classes, real interest rates have not been “stable”, and that since the major monetary upheavals of the late middle ages, a trend decline between 0.6-1.8bps p.a. has prevailed. A consistent increase in real negative-yielding rates in advanced economies over the same horizon is identified, despite important temporary reversals such as the 17th Century Crisis. Against their long-term context, currently depressed sovereign real rates are in fact converging “back to historical trend” – a trend that makes narratives about a “secular stagnation” environment entirely misleading, and suggests that – irrespective of particular monetary and fiscal responses – real rates could soon enter permanently negative territory. I also posit that the return data here reflects a substantial share of “nonhuman wealth” over time: the resulting R-G series derived from this data show a downward trend over the same timeframe: suggestions about the “virtual stability” of capital returns, and the policy implications advanced by Piketty (2014) are in consequence equally unsubstantiated by the historical record.
