Financialisation, Business Lending And Profitability In The Uk

This paper addresses the question whether business lending is still an important source of bank profits in the UK banking system. This research question is motivated by the effects of the process of financialisation. It has been argued that one of the consequences of financialisation is a dramatic change in business strategies by financial institutions, which have turned to new fields of profitability – namely, transactions in open financial markets and household/consumer lending – moving away from traditional business lending. However, the extent to which commercial banks have embraced financialisation and the contribution of business lending to bank profitability are likely to be the result of bank-specific characteristics. This paper investigates, therefore, whether the profitability of business lending is driven by bank heterogeneity or whether it is possible to identify systematic characteristics which affect it. Using bank level data from BankScope for a total sample of 83 UK banks and building societies for the period 2005-2009 and employing panel fixed effects estimation, we find very strong size effects: in particular, while business lending is a statistically significant source of bank profits, its quantitative importance varies dramatically across bank size. For large banks, business lending contributes to the rate of return on equity very little. This finding is not due to the occurrence of the financial crisis. Indeed, large size effects are found even when the financial crisis is controlled for. While we detected strong size effects, we could not detect any ownership effects. The profitability of business lending depends on whether banks are large or small, not on whether they are domestic or foreign. One possible policy implication of our findings is that capital injections into the larger banks per se are unlikely to lead to an expansion of credit to business.
