The Real Effects of Zombie Lending in Europe

Belinda Tracey

‘Zombie lending’ occurs when a lender supports an otherwise insolvent borrower through forbearance measures such as repayment holidays and temporary interest-only loans. The phrase was first coined for Japan in the late 1990s, but more recently several authors have documented that zombie lending to European firms has been widespread following the sovereign debt crisis (see Acharya et al (2019), Adalet McGowan et al (2018), Banerjee and Hofmann (2020), Blattner et al (2018) and Schivardi et al (2017)). In a recent paper, I examine whether these lending practices contributed to the subsequent low output experienced by the euro area. My findings suggest that zombie lending had negative consequences for output, investment and productivity in the euro area over the period 2011 to 2014.

How does zombie lending affect economic performance?

Zombie lending can lower output by misallocating funds across firms. By tying up credit to zombie firms, the flow of lending to more productive firms in the economy may be restricted, which lowers overall productivity. Several authors have argued that zombie lending to inefficient firms is not just a by-product of economic conditions but has in fact hampered the economic recovery in the euro area in recent years (see Acharya et al (2019), Blattner et al (2018) and Caballero et al (2008)). And these lending practices may ultimately have deleterious effects on banks’ balance sheets if they merely forestall firm liquidations.

But there are also potential benefits associated with zombie lending. It may not always involve lending to genuinely insolvent firms but rather firms with good long-term prospects experiencing a temporary period of weak demand. The Covid-19 crisis is a good example where these benefits are more likely to exist than in the economic setting covered by my paper. While it is too early to ascertain whether this applies to zombie lending activities in the euro area, there is some evidence that it may have been relevant for the Japanese case. Fukuda and Nakamura (2011) show that the eventual bankruptcy of Japanese firms who benefited from zombie lending was rare and that most of these firms recovered in the 2000s. They argue that if these supposed zombie firms were truly inefficient, the zombie lending they received would not have prevented their ultimate insolvency.

A model of zombie lending

To assess the impact of zombie lending practices on firm behaviour and economic performance, I develop a dynamic model of heterogeneous firms that incorporates a role for forbearance lending.

The model includes the following four key ingredients: (i) firms can borrow from a lender to finance their operations; (ii) firms can default on their loan obligations, leading to either their liquidation or a form of ‘zombie lending’; (iii) zombie lending takes the form of renegotiation over a reduction to the outstanding loan repayment; and finally (iv) lenders have incomplete information when making a loan because they do not know precisely whether a firm is ‘low quality’ or ‘high quality’, where the former firm type have lower average productivity than the latter. Rather, lenders rely on the partial information they can observe to determine the probability that a firm is low quality (ie the ‘firm-type risk’).

What I find

The model is fitted to euro-area firm-level statistics over the period 2011 to 2014, a period marked by higher levels of zombie lending (Acharya et al (2019)). The fitted model represents a ‘benchmark scenario’ with zombie lending. To evaluate the impact of zombie lending, I conduct a counterfactual exercise in which firms still have the option to default and liquidate but no longer have access to any zombie lending option.

The results can be summarized as follows. I first show that the rate of firm liquidation is only a little higher in the counterfactual scenario with no zombie lending as compared to the benchmark scenario. This is the net result of two effects. First, in the absence of zombie lending, the probability of liquidation for a given level of capital increases because liquidation is now the only default option (Chart 1). Second, and in turn, loan schedules become more expensive, as lenders take account of this increased risk of liquidation in their loan pricing (Chart 2), which results in firms taking on significantly less leverage, ie they choose smaller loans. The overall effect is that the counterfactual liquidation rate (ie proportion of firms that are actually liquidated) is little changed from the benchmark scenario.

Chart 1: Firm liquidation probabilities

Note: The figure plots how the liquidation probabilities vary with the size of a firm’s capital choice. The liquidation probabilities are on average higher in the counterfactual with no forbearance. But firms respond by making different choices about their leverage and so the liquidation rate is little changed in the counterfactual. A firm’s choice of capital depicted by the x-axis is scaled by the average level across firms.

Chart 2: Loan interest rate schedules

Note: The figure plots how the loan interest rates vary with the size of the loan repayment. The interest rate loan schedules are on average higher in the counterfactual with no forbearance. A firm’s loan repayment depicted by the x-axis is scaled by the average level of capital across firms.

The average of firms’ growth, investment rates and total factor productivity are higher in the counterfactual scenario with no zombie lending. A key driver of these results is that there is a larger proportion of high-quality firms in our counterfactual scenario; the zombie lending that is present in the benchmark scenario prevents low-quality firms from liquidating, which is a drag on aggregate output, investment and total factor productivity. Specifically, I find that aggregate output, investment and total factor productivity are around 5%, 8% and 1% higher in steady state in our counterfactual scenario with no zombie lending. These findings suggest that zombie lending practices may have been one of the contributing factors in relation to the recent low output across the euro area.

Why do zombie firms get credit?

An important question is: why do primarily low-quality firms receive zombie lending in our benchmark scenario, given a profit maximising bank would not ordinarily want to throw good money after bad by lending to a firm it judges to have poor prospects?

Several authors argue that the answer lies in the fact that lenders face zombie lending incentives in order to avoid the declaration of non-performing loans on their own balance sheets (see Andrews and Petroulakis (2019), Acharya et al (2019), Blattner et al (2018), Caballero et al (2008), Jordà et al (2020), Schivardi et al (2017) and Storz et al (2017)). My model highlights that information asymmetry faced by lenders is another key driver. Lenders do take account of firm-type risk. But because they cannot perfectly predict firm quality, the interest rate schedule is more favourable than otherwise for low-quality firms, and vice versa for high-quality firms. The end result is that the vast majority of firms in receipt of zombie lending are low quality because credit is (mis-)allocated to these firms with higher default risk.

Further questions

While the model provides new findings about the impact of forbearance lending on firms’ financial decisions and their dynamics, some related questions remain unanswered. For example, the model does not incorporate a role for ‘zombie lending incentives’ but rather focuses on how zombie lending affects the firm behaviour and economic performance. Similarly, the model does not include any role for the potential increased unemployment associated with higher firm liquidation rates. Zombie lending could mitigate aggregate demand externalities if these lending practices can prevent an increase in unemployment (see Haldane (2017)). But given that I do not find that liquidation rates increase significantly in the absence of zombie lending, this suggests a smaller role for such a potential offsetting channel. Nonetheless, a full examination of whether the costs of zombie lending, due to lenders misallocating credit, outweigh the benefits, due to preventing an increase in unemployment, presents an exciting avenue for future research.

  1. At last. Thanks Belinda for this report.
    Sadly as you may note from previous comments Zombies have been able to survive because of low interest rates and the some Bond policies of central banks.
    The impact? Mis allocation of resources and low productivity?
    Hopefully the penny will finally drop within the BOE?

  2. ZOMBIE/Junk lending/debt survives due to rates and buyers reaching for higher yields, even though low but higher than good quality debt. Debt Deflation is and will take hold and much of this Zombie debt prices will drop like a rock. Yields will rise on US Treasuries and other Sovereign Debt, which lead to other Yields rising in all other Debt,

    Make no mistake Yields will rise, Central Banks do not control the rates, its the Market that sets the rates and Central Banks and others follow.

    The Zombie Companies are already having trouble servicing their Debt, as Yields rise the problems will increase. Zombie debt is non self liquidating. Debt Deflation will take its toll on the Bond MKTS.

  3. The UK Government has no coherent strategy to deal with the eventual collapse of the Corporate Debt Bubble. It needs one. I refer the reader to the Ambition 2030 report put out by the Covid Recovery Commission as a response to the economic shock of the Pandemic. It has echoes of the Plan for the New Economy put forward by the Commission on Economic Justice in 2018. The Plan was itself a reworking of the Alternative Economic Strategy put forward by Tony Benn as a mechanism to escape the Common Market. From these, we see that ‘Command and Control’ systems for economic recovery still have a grip on the collective imagination of BEIS, despite the contrary fixation shown by DIT for globalised trade deals. But the real value of a ‘Command and Control’ economic plan does not lie in picking winners in advanced manufacture or ‘Green’ technology: it should be applied instead to manage the wave of corporate insolvencies that will follow from the next financial crisis. To do this, the UK Government should set itself up as the insolvency practitioner of last resort. ‘Command and Control’ measures could be used to coordinate the restructuring of insolvent firms across entire sectors of the economy, to enable new companies to emerge shorn of debt and thereby boost their productivity. It would be a massive undertaking. But so is the task of rebuilding British industry after forty years of globalisation and offshoring. Legal tools can be applied to assist. British business is now already familiar with the idea of the Government taking ‘debt for equity’ stakes in failing companies as an alternative to outright nationalisation. The new Corporate Insolvency and Governance Act 2020 contains a power for a cross-class cram-down of commercial debts in a restructuring plan. It remains to be seen how effective the Act will be in preventing ‘vulture funds’ from manipulating corporate valuations to achieve ‘loan to own’ outcomes. But that should be the aim of the Government. Having regard to the legislative steps that the Belgian Government has taken to hobble ‘vulture funds’ in exploiting sovereign debt, comparable initiatives need to be taken to make the UK corporate space as unattractive as possible for exploitative behaviours in insolvency practice.
