Air temperature and sovereign bond returns

Abstract

AbstractThe relationship between air temperature and sovereign bond returns is founded on competing paradigms: macroeconomic, behavioral and energy demand‐based. Which of these theoretical mechanisms receives support from data? To answer this, we examined four decades of bond data from 31 countries. Overall, daily temperature positively affects government bond returns. A 10°F rise leads to an increase in sovereign bond returns between 0.22 and 0.85 basis points. We also document evidence of asymmetric and nonlinear price responses to both temperature levels and shocks. Our results survive a battery of robustness checks and lend support to the macroeconomic and behavioral paradigms, albeit not the energy demand‐based view.
