Why will the correlation between long-term interest rates and share prices be different for a long time?
The normal correlation between long-term interest rates and share prices is positive: they fall in recessions and rise in periods of growth. But we are now moving to a new regime dominated not by the economic cycle, but by liquidity. The abundance of liquidity is leading, at portfolio equilibrium, to a rise in both bond prices and share prices, and therefore to a negative correlation between long-term interest rates and stock market indices .
