133: Why Has the U.S. Stock Market Increased by 300%?


The root causes of the U.S. corporate bond and stock market bubble are the ultra-low interest rates. Though interest rates have been falling since the 1980s, the trend has been supported by the Federal Reserve since the Great Recession of 2008 and 2009.

In an effort to jump-start their economies after the recession, central banks cut interest rates to record low levels and pumped trillions of dollars worth of liquidity into the global financial system and markets via their quantitative easing (QE) programs. The central bank-driven liquidity boom has led to "yield-chasing". That has sent bond prices soaring and yields plummeting, as shown in the following the chart:(1)


While the climbing U.S. stock market received attention, a dangerous bubble has been forming in the corporate bond market. This bond bubble is one of the main reasons why the stock market has been consistently pushing to new highs. The purpose of this Post is to explain why the corporate bond bubble poses a risk to the stock market and economy.

The Fed printed brand new fiat money and used it to buy Treasury bonds and mortgage-backed securities. These programs helped to boost the overall bond market. The chart below shows the growth of the Fed's balance sheet since the Great Recession as it created over $3.5 trillion worth of new money:


Low corporate bond yields have encouraged U.S. public corporations to borrow heavily in the bond market since 2007. Total outstanding non-financial corporate debt has increased by over $2.5 trillion, which is a dangerously high level. U.S. corporate debt is now at an all-time high of over 45% of GDP, which above the levels reached during prior excessive pricing conditions. 

Corporations have been using the proceeds of their borrowing to boost their stock prices via share buybacks, dividends, and mergers & acquisitions, instead of making the long-term business investments and expansions that were typical in the past. The chart below shows share buybacks and dividends. Share buybacks are expected to top $1 trillion this year:


The low interest rates and the debt-fueled share buybacks helped the S&P 500 to rise by over 300% from its lows and more than 80% from its 2007 peak:


U.S. corporations are using borrowed money to buy their own shares at very high valuations. That amounts to "throwing good money after bad." For instance the Shiller cyclically-adjusted price-to-earnings ratio (or CAPE) shows that the S&P 500 is hovering near 1929 valuations. The S&P 500 prices have been overvalued since the late-1990s:


Shiller cyclically-adjusted price-to-earnings ratio (or CAPE) now exceeds the perilous levels of the 1929 crash. This suggests a very high level of vulnerability and indicates that another recession may be now forming.

Summary:

The U.S. corporate debt bubble will burst due to tightening monetary conditions which includes rising interest rates. It is the loose monetary conditions that has created the current corporate debt bubble in the first place.  Ending of those conditions will puncture the corporate debt bubble. Falling corporate bond prices and higher corporate bond yields will  most likely cause the current stock buybacks to come to a screeching halt which will ultimately lead to the creation of a downward recessionary spiral. When that will happen is not certain because the government is still inducing rising corporate profits that will continue supporting rising stock market prices.
