Do elevated profit margins from larger deficits justify US equity valuations?
Core argument: The U.S. fiscal deficit averaged 6.6% of GNP over 2012–2022, more than double the just-under-3% average of 1950–2011, a pattern the author finds holds even when Covid years are excluded.
Between 1950 and 2011, the fiscal deficit averaged just less than 3% of GNP each year. In the period from 2012 to 2022, the fiscal deficit was more than double the previous average, at 6.6%. This isn’t just the impact of the pandemic: the same basic pattern holds even when I exclude the Covid years! The main sources of the increased deficit have been health spending and social security expenditure (again true even with Covid data excluded). Is this era of what Minsky would have called “Big Government” here to stay? Even if I take a very bullish view, that this is indeed a new era of permanent deficits and thus profit margins will remain elevated relative to history, I still cannot find any valuation attraction in U.S. equities in aggregate. The Shiller P/E naturally embodies the decade of higher-than-normal profit margins and yet still stands at 30x. Even without any valuation or margin mean reversion, this dooms investors to low returns in the long run.
