Between Debt and the Devil by Adair Turner: Study & Analysis Guide

Adair Turner’s Between Debt and the Devil challenges the foundational myths of modern finance, arguing that the very engine of our economic growth—private credit creation—is also the primary source of financial instability and inequality. Written by a former chairman of the UK’s Financial Services Authority, the book moves beyond diagnosing the 2008 crisis to proposing radical solutions that many policymakers still consider taboo. Understanding Turner’s thesis is crucial for anyone grappling with the persistent problems of stagnant wages, skyrocketing asset prices, and the fear of the next inevitable crash.

The Illusion of Neutral Debt

The book begins by dismantling a comfortable assumption: that all debt is economically useful. Turner argues that societies suffer from a debt illusion, the mistaken belief that rising debt is always a sign of productive investment. In reality, a vast portion of modern bank lending does not finance new business capital formation. Instead, it flows into existing assets, primarily real estate and financial instruments. When a bank grants a mortgage for a pre-existing house, it does not create new societal wealth; it simply increases the price of the house. This process generates asset price inflation, enriching asset holders while leaving non-holders further behind. This type of credit expansion creates claims on future income without expanding the economy’s capacity to generate that income, setting the stage for crisis when debt burdens become unsustainable.

The Banking System as an Engine of Instability

At the heart of Turner’s analysis is the mechanism of endogenous money creation. Contrary to the textbook model where banks are mere intermediaries of existing savings, Turner explains that banks create new money ex nihilo (out of nothing) whenever they make a loan. The decision to extend credit is driven by private profit motives and perceptions of collateral value, not by a societal need for productive investment. This system, left unchecked, possesses an inherent pro-cyclical bias. In good times, rising asset prices increase collateral values, encouraging more lending, which pushes prices even higher—a dangerous feedback loop. In downturns, the process reverses, destroying money and contracting economic activity. Turner contends that this dynamic means financial instability is not an occasional bug in the system, but a central feature of financially advanced economies.

The Debt Trap and the "Devil’s Choice"

When a crisis arrives, economies face what Turner calls the devil’s choice. Policymakers must select between two painful paths: protracted austerity to deleverage the private sector, which crushes growth and employment, or aggressive monetary stimulus (like near-zero interest rates and quantitative easing) to encourage renewed borrowing. The latter option, however, simply re-inflates the asset price bubble and piles more debt onto an already over-leveraged system, preparing the ground for the next crisis. This trap explains the post-2008 phenomenon of "secular stagnation"—chronically weak demand despite ultra-low interest rates. The private sector, saturated with debt, refuses to borrow and spend more, rendering conventional monetary policy impotent.

A Controversial Escape Hatch: Overt Monetary Financing

Turner’s most provocative proposal is the controlled use of overt monetary financing (OMF) of fiscal deficits. Also known as "helicopter money" or a permanent money-financed fiscal stimulus, this involves the central bank creating permanent, non-repayable money to fund government spending or tax cuts. Unlike quantitative easing, which buys assets from financial institutions with the hope they will lend, OMF would place money directly into the real economy. Turner argues this could stimulate demand, reduce the over-reliance on private credit for growth, and help manage down excessive debt burdens without a deflationary depression. He is careful to prescribe this as a one-off, rule-bound tool for deep recessions or debt traps, not a routine funding mechanism for government.

Critical Perspectives

While Turner’s diagnosis of excessive credit creation is widely supported by post-crisis economic analysis, his therapeutic prescription remains deeply controversial. The primary objection is the historical association of money-printing with hyperinflation, as in Weimar Germany or Zimbabwe. Critics argue that once the taboo is broken, it becomes politically impossible to limit OMF to emergency scenarios, risking a loss of central bank independence and fiscal discipline. Furthermore, some economists question whether the distributional effects of the chosen fiscal spending (e.g., infrastructure vs. tax cuts) could be adequately managed or politically agreed upon. Turner counters that the greater danger lies in remaining trapped in a cycle of debt-driven booms and busts, and that OMF, governed by clear legislation, is a lesser risk than permanent economic dysfunction.

Summary

• Private credit is not neutral: A large portion of bank lending fuels asset price bubbles rather than productive investment, creating instability and inequality.
• The system is inherently unstable: The endogenous nature of bank money creation drives pro-cyclical booms and busts, making severe financial crises a recurring feature.
• Conventional policy is trapped: After a major crisis, the choices between austerity and ultra-low interest rates both have severe, long-term negative consequences.
• A radical tool may be necessary: Turner argues for a strictly controlled, one-off use of overt monetary financing (central bank money funding fiscal deficits) to escape deep debt traps.
• The proposal is high-risk: The primary critique centers on the immense difficulty of constraining such a powerful tool and the perennial fear of unleashing uncontrollable inflation.
