How should the rise in the equity risk premium be interpreted?
The equity risk premium has risen as a trend in the United States and the euro zone. How should this be interpreted? It may stem from : The decline in long-term interest rates, if equity investors expect it to be temporary and not long-lasting: they would then discount future profits with a higher interest rate than the market rate; A rise in risk aversion; A rise in the supply of equities. An econometric analysis shows that long-term interest rates have had a significant effect , risk aversion has had a smaller effect , while share buybacks have had an effect in the United States. This suggests that equity investors are going to have to accept the idea that long-term interest rates will remain low for the equity risk premium to truly fall.
