Together we think these secular trends can account for 300bps of the historic decline in the global real rate. Moreover, we think these secular trends are likely to persist. This suggests the global neutral rate, which acts as an anchor for individual countries’ equilibrium rates in the long-term, will remain low, perhaps around 1%.
