When should central banks engage in private sector securities purchases?

Journal of Economic Studies, 2023, vol. 50, issue 5, 1027-1047

Abstract: Purpose - The authors aim to look at the conditions under which central bank easing – and specifically the purchase of private sector securities – can/should contribute to growth, rather than fiscal policy and also ask when can the central bank’s purchase of private sector securities help supplant traditional monetary policy. Design/methodology/approach - After surveying the existing literature, the authors use simple correlation of central bank private asset (stocks, bonds, etc.), interest rates, gross domestic product (GDP) growth, inflation and the extent of the functioning of domestic banking sectors (among others) to classify countries in which these purchases promote pro-growth investment. Findings - Under the typical conditions for unconventional monetary policy, central bank purchases of private companies’ securities can promote growth in some places (like Bulgaria, the Ukraine, Georgia and Greece at the time of our writing) while hurting it in others (like in parts of Latin America and Africa in the mid-2010s). The authors find how such purchases effectively “bypass” dysfunctional banking systems and central/government local bodies fiscal spending, making the central bank the “funder of last resort” in many middle and lower income countries. Practical implications - This paper tells specific central banks to ramp up – or reduce – their purchases of private sector securities. The authors identify exact jurisdictions where such “helicopter money” has led to investment in the past economic growth. Originality/value - All previous work on conventional and unconventional monetary policy has looked at the way monetary policy affects investment and growth through the banking system and holding companies’ reactions constant. The authors do the opposite – looking at how companies respond, holding banking system responses constant. No one has ever looked at these private purchases (taken from a special IMF database), much less tried to argue that central banks can sometimes target investment growth much better than fiscal policy. No one has ever considered them as a funder (rather than lender) of last resort.
