What if bonds are not overpriced? Here’s an alternative view

Analysis

Research Affiliates, arguably the inventors of ‘smart beta’, have raised the question that even though interest rates may be pushed up soon due to regulatory action, it is possible that bond prices are not in a bubble. Contrary to the consensus, maybe sovereign bonds are at fair value.

In a recent paper, Californian-based Research Affiliates, headed by Rob Arnott, of smart beta fame, says:

  • Contrary to common wisdom, low yields do not imply that US Treasury securities are expensive
  • After accounting for macroeconomic trends, Treasury bonds are only moderately overvalued
  • A proper valuation of the bond market requires going beyond simply blaming the Fed’s unprecedented policies of monetary easing, and
  • Given their recent negative correlation with stock returns, Treasury bonds may not be as unattractive as one might think.

The paper, written by Michele Mazzoleni and Ashish Garg, says:

  • “In the frantic months following the fall of Lehman Brothers in 2008, the US Federal Reserve embarked on an unprecedented program of unconventional monetary policy easing. This program included purchases of mortgage-backed securities as well as

    “Treasury bonds, and it continued until October 2014, well beyond most people’s expectations. The large degree of uncertainty associated with the effects of these policies logically led to a wide range of predictions from commentators and practitioners, including the downfall of the US dollar, rapidly rising inflation, and the build-up of a significant bubble in the Treasury bond market. These scenarios, albeit dramatic, were all reasonable possibilities within a highly uncertain economic evolution.

    “Ten years after the onset of financial troubles, the view of policy makers and investors has changed. On the shoulders of a moderate but persistent economic expansion, the US dollar has appreciated against major foreign currencies. Despite an unemployment rate at or below its natural level, core inflation has proven to be stubbornly low, forcing policy makers to reluctantly question their ability to influence prices (e.g., Cochrane, 2017). Yet this benign economic prognosis has hardly changed one belief: policies of easy money have pushed the Treasury bond market into bubble territory (e.g., Mooney, 2017).

    “One may be forgiven for blaming the Federal Reserve; given the long-lasting expansion, a 10-year Treasury note yielding just little above 2 per cent does feel expensive. A notably slow process of policy normalisation has failed to push long-term interest rates closer to their historical values.

    “Moreover, the US stock market has also been on a multi-year run, which is inducing asset managers to speculate on the sustainability of current valuations across US capital markets.1 If a lower dividend yield is associated with expensive equities, then a lower bond yield should indicate expensive Treasuries.

    “We challenge the conventional wisdom. Different from equities, the empirical evidence shows that low Treasury yields do not necessarily imply expensive bonds. Indeed, our research shows that macro fundamentals are major drivers of real interest rates and largely explain the historically low yield environment. “Whereas bonds do appear overvalued, we should not mistake a new normal of expected lower returns for a bond bubble. In addition, returns are not the only dimension that should determine an investor’s asset allocation. Bond and stock returns have been negatively correlated over the last 20 years, suggesting that in the future Treasuries could again offer a hedge against stock market fluctuations.

    “Rightly or wrongly, the Federal Reserve has been a favourite foe of many in the market place. Yet just as policy makers acknowledge the limits of monetary policy, so should investors. In relative terms, Treasury bonds are not as unattractive as one might think.”
