This indicates to me that there can be significant and persistent deviations in the equilibrium real rate from the observed long-run average measured over decades. The average interest rate that seems to have brought aggregate demand and aggregate supply into rough balance in the past may not be the same rate required in every conjunctural setting.
It may seem like second nature now, but we only dreamed of having this ability 20 years ago. While these advances bring us great benefits, financial authorities must remain highly vigilant to the ever-present risk of cyber-attacks on our financial system.
