A new IJCB article shows that historically [i] inflation expectations had a strong impact on long-term yields and [ii] economic data surprises had a strong impact on inflation expectations. However, the influence of compensation for inflation and inflation risk on U.S. bond yields has faded in the era of non-conventional monetary policy.
More than a year after its launch, the impact of “quantitative and qualitative easing” seems pervasive. The Bank of Japan asserts that the output gap has closed, that inflation expectations have increased, and that the conquest of deflation would be in sight. The policy board has maintained its commitment to the 2% inflation target through forward guidance and large-scale JGB purchases. However, without successful fiscal consolidation and supply side reforms this policy poses new serious risks.
With G7 public debt stocks at record highs, inflation has become a key fiscal concern. A new IMF paper estimates that a fall of inflation to zero would raise debt ratios by another 5-6%-points. A rise of inflation to 6% would lower debt ratios by 11-18%-points of GDP through real debt erosion. Inflation would offer additional fiscal benefits, such as higher revenues through “seigniorage” and progressive income tax tariffs.
Warwick professor Nicolas Crafts notes that the UK’s exit from recession and deflation in 1930s has similarities to Japan’s current expansionary policy. At the time the UK managed recovery and reflation through very low rates and initial currency devaluation. Crafts argues that such strategies may require abandoning inflation-targeting independent central banks.
Macrosynergy is a London based macroeconomic research and technology company whose founders have developed and employed macro quantamental investment strategies in liquid, tradable asset classes, across many markets and for a variety of different factors to generate competitive, uncorrelated investment returns for institutional investors for two decades. Our quantitative-fundamental (quantamental) computing system tracks a broad range of real-time macroeconomic trends in developed and emerging countries, transforming them into macro systematic quantamental investment strategies. In June 2020 Macrosynergy and J.P. Morgan started a collaboration to scale the quantamental system and to popularize tradable economics across financial markets.
