GMO is a Boston asset manager co-founded in 1977 by Jeremy Grantham with Richard Mayo and Eyk Van Otterloo, known for valuation-driven dynamic asset allocation built on long-horizon mean reversion. Grantham is famous for calling historic bubbles, warning publicly ahead of both the 2000 dot-com crash and the 2008 financial crisis. Flagship publications include the GMO Quarterly Letter (now written by Asset Allocation co-heads Ben Inker and John Pease), Grantham's Viewpoints essays and the 7-Year Asset Class Forecast.

This report argues that rich countries' economic growth has slowed down, and with climate change and COVID-19, we need a big government spending plan like the post-WWII Marshall Plan—but for green infrastructure (like clean energy and electric buses). For regular investors, this means future opportunities may shift to these areas, and we shouldn't worry too much about government debt because interest rates are very low, making borrowing cheap. It's worth reading because it explains why now might be a good time to invest in green industries.
GMO Chief Investment Strategist Jeremy Grantham points out that the world faces the dual challenges of a climate crisis and the COVID-19 pandemic, urgently requiring large-scale public investment akin to the Marshall Plan to upgrade energy, transportation, and industrial infrastructure. The report a
This chapter discusses the predicament of long-term economic growth slowdown in developed countries, rising income inequality, the climate crisis, and the overlapping impact of the COVID-19 pandemic. The author, Jeremy Grantham, argues that the current environment of negative real interest rates offers a once-in-several-decades window for large-scale public investment. He believes the new U.S. administration should launch a green infrastructure fiscal stimulus plan akin to the Marshall Plan.
1. Long-Term Economic Growth Slowdown: Real GDP growth in developed countries has fallen from over 4% in the 1960s to less than 2% currently (as shown in Exhibit 1 data). This trend is masked by the short-term boom of a few tech companies like FAANG.
2. Debt Concerns Exaggerated: The author argues that debt is double-entry bookkeeping, with every $1 of debt corresponding to $1 of credit. Current negative real interest rates make long-term risk-free borrowing costs extremely low, making the interest coverage ratio the key metric.
3. Lessons from 2009: The U.S. mistakenly allocated resources in 2009-2010 to bail out insolvent banks (rather than addressing liquidity issues), which violated the spirit of capitalism. This time, infrastructure should lead the fiscal plan.
4. Returns on Green Infrastructure: The global green transition requires decades and tens of trillions of dollars in investment, but the returns on green infrastructure investment are substantial. If financed at negative real interest rates, it would be "the best business deal in history."
5. U.S.-China Comparison: The U.S. has only 400 electric buses, while China has 400,000 (a 100-fold difference). Green energy and industry will become key areas of future geopolitical competition.
Annual real GDP growth in developed countries has steadily declined from over 6% in the 1960s to less than 2% in recent years, with a forecast drop to approximately -4% in 2020.
