Zombie Companies and the Cost of Free Capital: What Schumpeter Would Have Said

Joseph Schumpeter's concept of creative destruction rests on a mechanism that is easy to describe and politically difficult to allow: the elimination of unproductive capital. In Schumpeter's model, recessions perform a necessary function — they clear the economic landscape of firms and capital structures that are no longer viable, freeing resources for more productive deployment. The recession is the forest fire that makes new growth possible.

The ZIRP era was, among other things, an experiment in what happens when you suppress that mechanism for an extended period. The answer — increasingly documented in academic research and visible in economic data — is the proliferation of zombie companies: firms that cannot generate sufficient operating cash flow to cover their debt service but can survive by continuously refinancing at low rates.

The definition and the data

The most commonly used definition of a zombie company, developed by economists at the Bank for International Settlements, is a firm that has been in existence for at least ten years, is publicly listed, and has had an interest coverage ratio below one — meaning operating earnings are insufficient to cover interest expense — for three or more consecutive years.

By this definition, the share of publicly listed zombie companies in advanced economies rose from roughly 2 percent in the 1980s to approximately 15 to 16 percent by the late 2010s. The BIS research, published in 2018, found that the rise in zombie firms was correlated with declining interest rates and was concentrated in sectors with high capital intensity and significant debt loads — exactly the sectors where low rates provided the greatest refinancing benefit.

The ZIRP era suppressed Schumpeter's mechanism of creative destruction for over a decade. The costs are still being counted.

What zombies actually cost

The cost of zombie companies is not primarily the capital tied up in them — though that is real. It is the spillover effects on the rest of the economy. BIS research found that zombie firms crowd out investment and employment at healthy firms — they compete for workers, for customers, and for credit, often at subsidized effective rates made possible by their creditors' reluctance to recognize losses. The healthy firms that would grow in a normal environment are constrained by competition from zombies that should not exist.

The productivity implications are significant. Aggregate productivity growth in advanced economies decelerated markedly during the ZIRP era — a period in which technological capability was, by most measures, advancing rapidly. The coexistence of technological progress and productivity deceleration is easier to explain if you account for the misallocation of resources toward zombie firms that the technology should have displaced.

What Schumpeter would have said

Schumpeter was not a cruel man, but he was a clear-eyed one. He understood that the political economy of creative destruction was its central problem: the beneficiaries of destruction are diffuse and future-oriented (the new firms that replace the old ones, the workers who will eventually find better employment), while the costs are concentrated and immediate (the workers who lose jobs today, the shareholders who lose capital, the communities whose anchor employers close). Democratic systems consistently underweight the diffuse future benefits and overweight the concentrated immediate costs.

He would have recognized ZIRP-era zombie preservation as exactly this dynamic: a politically rational but economically costly decision to protect concentrated losers at the expense of diffuse future winners. He would not have been surprised by it. He would have noted that the costs compound — that each year of zombie survival is a year of misallocated capital and suppressed competitive pressure on the survivors, and that the eventual reckoning, when rates normalize, is larger and more disruptive than the earlier, smaller reckonings that were avoided.

The normalization reckoning

The 2022 rate cycle is testing zombie balance sheets in real time. Companies that refinanced at 2 and 3 percent through the ZIRP era are facing maturities in a 5 to 7 percent environment. The private credit market has absorbed much of this stress — providing bridge financing at high rates that allows technically insolvent businesses to continue operating — but this is Schumpeterian reckoning deferred, not avoided.

Schumpeter understood that capitalism's creative energy and its destructive energy are the same energy. Policies that suppress the destruction suppress the creation. The zombie company problem is not a curiosity — it is the measurable cost of a decade of suppressed creative destruction, still working its way through the system.
