Household Debt Repayments

Abstract

Why do households repay their debt during COVID-19 crisis? Well-being and financial implications’, the study will examine the impacts of COVID-19 policy interventions on household debt repayments and financial resilience.
Bank of England statistics show that households repaid £7.4 billion of consumer credit in April 2020, the largest net repayment on record. Researchers at Birkbeck, University of London, University of Zurich and Lancaster University will explore the role of monetary expansion, debt repayment moratoriums, lockdowns and furloughing in household debt repayment, controlling for specific characteristics such as ethnicity, age, gender, health and employment.
The study will also examine persistence on both household debt repayments and debt exposure. Recent statistics show that British households have increased their debt exposure by £6 billion as they fall behind on credit card payments, council tax and utility bills. The study will deliver evidence and projections that will inform policy making decisions in real time and enhance impact.
