Principles for Navigating Big Debt Crises
Free PDF at economicprinciples.org; first issued as A Template for Understanding Big Debt Crises.
Summary
Dalio sets out a template for how large debt crises unfold and then tests it against forty-eight case studies, of which three are examined in detail: Germany in 1918 to 1924, the United States in 1928 to 1937, and the United States in 2007 to 2011. The book is in three parts, being the archetype, the detailed cases, and the compressed data on the remaining forty-five.
The framework separates deflationary debt crises, where the debt is in the country's own currency and the central bank can print, from inflationary crises, where debt is in a foreign currency and printing does not help. He describes a sequence of phases: the early part of the cycle, the bubble, the top, the depression, the beautiful deleveraging, and the pushing on a string phase. The central claim is that policymakers have four levers, being austerity, debt defaults and restructurings, transfers of money from those who have to those who do not, and money printing, and that outcomes depend on the mix. A beautiful deleveraging happens when printing is large enough to offset deflationary forces without generating unacceptable inflation.
The book's strengths are the case-by-case data and the fact that Dalio's firm used this framework to position through 2008, which gives it a track record. The weaknesses are structural: the template is descriptive rather than predictive, it does not specify how to identify the phase you are in at the time, the writing is repetitive, and the analysis of the political economy of deleveraging is thin. Academic economists have criticised the mechanical treatment of debt-to-income ratios. Bridgewater makes it available free, which tells you it functions partly as a marketing document for the firm's worldview.
Key takeaways 7
- Debt crises follow a repeating sequence because debt growth must eventually exceed income growth, and the pattern differs depending on whether the debt is denominated in the country's own currency.
- Policymakers have exactly four tools for a deleveraging, being austerity, default and restructuring, wealth transfers, and money printing, and only the mix determines whether the outcome is orderly.
- A deleveraging goes well when money printing is large enough to offset the deflationary effect of defaults and austerity without producing a currency collapse.
- Austerity alone always fails, because cutting spending reduces the income against which the debt is measured.
- Central banks that act early and at sufficient scale shorten depressions substantially, and the 2008 response was faster and larger than the 1930s one for that reason.
- Debt crises in a foreign currency cannot be resolved by printing and therefore produce currency collapses and inflation instead of deflation.
- The top of a debt cycle is identifiable from debt service growing faster than income and from new lending going to fund asset purchases rather than productive investment.
