Macroscope | The real danger of the ESG investment boom is not a stock bubble
- What really matters is not the ‘greenness’ of ESG stocks or green bonds but how these distract from the critical issue of countering climate disaster
- A more officially coordinated and institutional approach is needed rather than corporate and financial sector ‘do-gooding’

This seemed like sacrilege given the reverence for “green” investing, but Eiji Hirano, former chairman of Japan’s Government Pension Investment Fund, is not alone in questioning the cult of ESG investing.
Estimates of how big the ESG market is vary hugely according to definition, but there is no denying that it has reached trillions of dollars. As such, ESG investing has become a major factor influencing how public savings flow into climate and other socioeconomic investments.
One reason that few challenge the ESG orthodoxy is that, as one Wall Street practitioner noted to me, the whole issue of sustainable investment (of which ESG forms the dominant part) is rather “fuzzy”. It is difficult to challenge that which you do not understand.
ESG is more or less whatever you want it to be, or rather, whatever asset managers want to project it as being. They, of course, have a vested interest in extolling its virtues because of the rich source of commission income that ESG investments represent, as veteran Japan securities analyst Jesper Koll notes.
