The global bond sell‐off – why and where next?

The rise in global bond yields since mid‐April has taken markets by surprise. Our analysis suggests that, on balance, some upward correction in yields was justified – especially in the Eurozone. For the US, the evidence is more mixed. A variety of explanations have been advanced to explain the bond sell‐off including Eurozone reflation/inflation, looming US rate hikes and associated uncertainty, liquidity and other technical factors, Chinese reflation and a simple reversal of yields overshooting to the downside. Some of these explanations are more convincing than others: in our view there is some modest evidence for increased uncertainty and liquidity effects but we also think bonds have corrected from overbought levels, especially in the Eurozone. Using some econometric models of bond yields suggests that the recent upward correction of German yields was probably justified; markets had pushed yields too low earlier in 2015. Indeed, the model implies a further ‘corrective’ rise in yields is possible. For the US, different models give slightly different results – a variant of the well‐known Shiller‐Modigliani model suggests yields should still be below 2%. However, a broader error‐correction model including factors such as fiscal variables and foreign flows into US bonds suggests the recent rise in yields was broadly justified.
