One of the most important questions in financial markets today is inflation. For a start, just the fear of central banks raising interest rates could cause sharp corrections in financial markets. After all, economists are squabbling over what really causes inflation and cannot agree on how much inflation risk there is. After that, the continued fiscal boost planned would create excess demand and so result in high inflation. Financial markets will be nervous, though, producing swings in capital flows in and out of our equity and bond markets.
