The recent decline in the US stock market, after the longest bull market in history, has prompted many commentators to focus on the negative factors which could sow the seeds of the next recession. Among the main concerns is the inexorable rise in debt since the great financial recession (GFR) of 2008. According to May 2018 data from the IMF, the global debt now stands at $63trln, with emerging economy debt expansion, over the last decade, more than offsetting the marking time among developed nations. The IMF – Global Debt Database: Methodology and Sources WP/18/111 – looks at the topic in more detail.
The title of this week’s Macro letter comes from the poet Stevie Smith:
I was much further out than you thought
And not waving but drowning.
It seems an appropriate metaphor for valuation and leverage in asset markets. In 2013 Thomas Pickety published ‘Capital in the 21st Century’ in which he observed that income inequality was rising due to the higher return on unearned income relative to labor. He and his co-authors gathering together one of the longest historical data-set on interest rates and wages – an incredible achievement. Their conclusion was that the average return on capital had been roughly 5% over the very long run.
This is not the place to argue about the pros and cons of Pickety’s conclusions, suffice to say that, during the last 50 years, inflation indices have tended to understate what most of us regard as our own personal inflation rate, whilst the yield offered by government bonds has been insufficient to match the increase in our cost of living. The real rate of return on capital has diminished in the inflationary, modern era. Looked at from another perspective, our current fiat money and taxation system encourages borrowing rather than lending, both by households, corporates, for whom repayment is still an objective: and governments, for whom it is not.
Financial innovation and deregulation has helped to oil the wheels of industry, making it easier to service or reschedule debt today than in the past. The depth of secondary capital markets has made it easier to raise debt (and indeed equity) capital than at any time in history. These financial markets are underpinned by central banks which control interest rates. Since the GFR interest rates have been held at exceptionally low levels, helping to stimulate credit growth, however, that which is not seen, as Bastiat might have put it, is the effect that this credit expansion has had on the global economy. It has led to a vast misallocation of capital. Companies which would, in an unencumbered interest rate environment, have been forced into liquidation, are still able to borrow and continue operating; their inferior products flood the marketplace crowding out the market for new innovative products. New companies are confronted by unfair competition from incumbent firms. Where there should be a gap in the market, it simply does not exist. At a national and international level, productivity slows and the trend rate of GDP growth declines.
