In academic and policy circles there is deep mistrust of public sector involvement in credit allocation, much more than in the credit allocation decisions made by commercial banks. This mistrust continues, despite the financial crisis of 2007–08 demonstrating the huge dangers of a deregulated credit market. Whilst, post-crisis, financial regulators have begun to develop policies aimed at reducing lending in certain sectors, calls for proactively directing finance to support desirable sectors of the economy have largely been ignored.
In a new UCL Institute for Innovation and Public Purpose (IIPP) working paper, co-authored with Dutch economists Dirk Bezemer and Lu Zhang and Frank van Lerven, we examine the theoretical, historical and empirical evidence around credit policy and its effects on the allocation of credit.
Our motivation, aside from the crisis, is the remarkable ‘debt shift’ in advanced economies over the past 40 years which has seen banks move away from their primary textbook role of lending to non-financial firms to support productive investment. Whilst total bank credit has roughly doubled relative to GDP since the early 1970s in advanced economies, the share of credit supporting firms has actually fallen, from 60% to 40%. The vast expansion in lending has been mainly to support households to buy houses and, to a lesser extent, consumer goods and the purchase of financial assets.
Total credit and business credit share in advanced economies, 1973–2005. Data is averaged across 17 advanced economies.
Mortgage and other asset-market lending typically does not generate income streams sufficient to finance the growth of debt. Instead, the empirical evidence suggests that after a certain point relative to GDP, increases in mortgage debt typically slows growth and increase financial instability as asset prices rise faster than incomes.
These new empirical findings support a much older body of theory that argues that credit markets, left to their own devices, will not optimise the allocation of resources. Instead, following Joseph Schumpeter’s, Keynes’ and Hyman Minsky’s arguments, they will tend to shift financial resources away from real-sector investment and innovation and towards asset markets and speculation; away from equitable income growth and towards capital gains that polarises wealth and income; and away from a robust, stable growth path and towards fragile boom-busts cycles with frequent crises.

This means, we argue, there is a strong case for regulation, including via instruments that guide credit. In fact, from the end of World War II up to the 1980s, most advanced economy central banks and finance ministries routinely used forms of credit guidance as the norm, rather than the exception. These include instruments that effected both the demand for credit for specific sectors (e.g. Loan-to-Value ratios or subsidies) and the supply of credit (e.g. credit ceilings or quotas and interest rate limits).
In Europe, favoured sectors typically included exports, farming and manufacturing, while repressed sectors were imports, the service sector, and household mortgages and consumption. Indeed, commercial banks in many advanced economies were effectively restricted from entering the residential mortgage market up until the 1980s. Public institutions — state investment banks and related bodies — were also created to specifically steer credit towards desired sectors.
The financial liberalisation and deregulation of the 1980s saw the gradual removal of credit guidance and credit control policies which were seen to distort the efficient allocation of capital. This was a key element of the ‘Washington Consensus’ pushed by the World Bank and the IMF to developing countries. Many State Investment Banks were also privatised.
Our empirical investigation of the relationship between credit policy and credit allocation examines two time periods with different samples. Firstly, for the 1973 to 2005 period, for advanced economies, we find that the liberalisation of credit markets and removal of credit guidance is significantly associated with a lower share of lending to non-financial firms, supporting the Schumpeter-Keynes-Minsky hypothesis.
In a second sample sample, for the 2000 to 2013 period, we use a wider sample of countries, including emerging markets. In this period, there has been somewhat of a shift by financial regulators back towards the use of credit controls, following the emerging market economy crises’ of the late 1990s and early 2000s and, in advanced economies, following the global financial crisis of 2007–08. However, for this period we do not find a significant relationship between the introduction of these ‘macro-prudential’ policies and the share of lending to non-financial firms.
We hypothesise this may be related to post-2000 interventions being primarily focused purely on financial stability concerns rather than economic growth and the need to steer credit towards productive sectors of the economy. We conclude that both types of credit policy may be needed.
The debate about the pros and cons of credit guidance is not a closed case and the empirical evidence presented in our paper raises as many questions as it answers. More detailed empirical and qualitative research, examining examples where credit guidance policy has been both successful and less so, is required going forward.
However, given the huge challenges facing modern economies, not least the need to rapidly transition to low-carbon economies, financial policy-makers should be encouraged to experiment with credit guidance policies to support sustainable and inclusive growth, while also maintaining a focus on financial stability issues. To do so, greater collaboration between central banks and ministries of finance and industrial policy will likely be necessary.
