Option-implied asymmetries in bond market expectations around monetary policy actions of the ECB

This paper uses data on German government bond futures options to examine the behaviour of market expectations around monetary policy actions of the European Central Bank (ECB). In particular, this paper focuses on the asymmetries in bond market expectations, as measured by the skewness of option-implied probability distributions of future bond yields. The results show that market expectations are systematically asymmetric around monetary policy actions of the ECB. Around monetary policy tightening, option-implied yield distributions are positively skewed, indicating that market participants attach higher probabilities for sharp yield increases than for sharp decreases. Correspondingly, around loosening of the policy, implied yield distributions are negatively skewed, suggesting that markets assign higher probabilities for sharp yield decreases than for increases. Furthermore, the results indicate that market expectations are significantly altered around monetary policy actions, as asymmetries in market expectations tend to increase before changes in the monetary policy stance, and to decrease afterwards.
