The inventory market capitalization-to-GDP ratio — the so-called Buffett Indicator — measures the size of the equity markets relative to the economy. Since company sector development is determined by financial development, the indicator’s two inputs are anticipated to maneuver in sync over the long run.
So What’s the Pattern in the US?
The Buffett Indicator’s trajectory during the last 50 years shows two major traits:
1. A Rising Pattern
The curve has been on a reasonably steady upswing, with a pronounced acceleration in recent times. What explains this habits? The non-public sector’s development as a proportion of the economic system might be one wrongdoer. This has occurred as the federal government’s contribution to GDP has regularly decreased during the last half century.

The expansion of the cash provide has additionally fueled this acceleration. The US Federal Reserve has steadily decreased rates of interest because the early Nineteen Eighties and the added foreign money this has injected into the system has helped propel the inventory market. With the onset of the worldwide monetary disaster (GFC) in 2007, the Fed instituted its quantitative easing (QE) program. Thereafter, the expansion in fairness market capitalization far outpaced that of GDP. In different phrases, QE helped the inventory markets greater than the economic system.

2. Intervals of Sharp Peaks and Troughs
The curve shows 4 cases of sharp peaks during the last half century. Every of the primary three preceded a burst inventory bubble and a recession earlier than hitting backside:
- 1972–1974: The Buffett Indicator peaked in 1972 at 0.85x after which fell till 1974. This corresponds with the recession of 1973–1975, which was due partly to the primary oil shock and the inventory market crash of 1973–1974.
- 1999–2002: The market cap-to-GDP ratio crested at 1.43x in 1999 after which declined, bottoming out in 2002. What occurred? The dot-com bubble burst, and the economic system fell into recession in 2001. The inventory market crested in 2000 and didn’t attain its lowest ebb till 2002. By that point, the Fed had slashed rates of interest, which helped revive the economic system and likewise contributed to the beginning of an actual property bubble.
- 2007–2008: The Buffett Indicator summited in 2007 at 1.03x earlier than falling to its nadir in 2008 amid the GFC and the recession of 2007–2009. The fairness market peaked in 2007 and didn’t begin to recuperate till 2009, when the Fed’s QE program started to kick in.
At the moment, we’re within the midst of the fourth peak. The one query is when it would attain its summit and start its descent.
Present Deviation from Pattern
The fairness market cap spiked versus nominal GDP after the beginning of QE in 2009. The present spherical of COVID-19-induced QE has widened this deviation even additional. The Buffett Indicator went into overpriced territory in 2013 when it crossed the 1.0x line. That successfully implied that publicly traded firms have been price greater than the entire financial manufacturing. Or that the market anticipated extraordinarily excessive financial development for the following a number of years.
On the finish of 2020, market cap-to-GDP stood at roughly 1.86x. This implies that public firms are actually nearly twice the scale of the economic system. The present mismatch between fairness market cap and GDP is the very best and most lasting within the final 50 years.
Expectations
Each time the market cap has deviated so sharply from GDP, it has snapped again simply as quickly. So if previous is any prologue, we will count on a swift fall in fairness markets. Whereas no person can name the height, among the many doable triggers for a downturn could possibly be shock insurance policies popping out of the Joseph Biden administration, renewed Fed tapering, worsening COVID-19 developments, or a world financial slowdown.
Timing the market is all the time a idiot’s errand, however the Buffett Indicator is flashing pink and has been for some time now, so warning is the watchword.
