How Balance Sheet Recessions Affect the Global Economy: Lessons from Japan, the US, and China



What is a balance sheet recession and why should you care? A balance sheet recession is a type of economic downturn that occurs when a large portion of the private sector is trying to reduce its debt rather than spending or investing. This can happen after a burst of an asset price bubble, such as the housing bubble in the US or the stock market bubble in Japan, that leaves many households and businesses with negative equity (their assets are worth less than their liabilities).

A balance sheet recession is different from a normal recession, where monetary policy (lowering interest rates or injecting liquidity) can stimulate demand and revive the economy. In a balance sheet recession, people with negative equity are not interested in borrowing more money, even at very low interest rates, because they want to repair their balance sheets and restore their credit ratings. Moreover, lenders are also reluctant to lend to those with impaired balance sheets, especially if they have their own balance sheet problems.

As a result, the private sector as a whole becomes a net saver rather than a net borrower, and aggregate demand falls sharply. This creates a deflationary spiral, where falling prices and incomes make it harder for debtors to repay their debts, further depressing demand and prices. The economy can get stuck in a prolonged slump, as happened in Japan for more than two decades after the collapse of its asset price bubble in the early 1990s.

The term “balance sheet recession” was coined by Richard Koo, the chief economist of Nomura Research Institute, who has studied the Japanese experience extensively and warned about the risks of similar scenarios in other countries. He argues that in a balance sheet recession, the government has to play a crucial role by running large fiscal deficits to offset the private sector’s savings surplus and support aggregate demand. He also advocates for debt restructuring and forbearance policies to help debtors recover from their negative equity and resume normal economic activities.

According to Koo, many Western economies have entered a balance sheet recession after the global financial crisis of 2008-2009, which was triggered by the burst of the US housing bubble. He points out the remarkable similarities between house price movements in the US this time and in Japan 15 years ago1. He also notes that massive injections of liquidity by central banks in the US and the UK have failed to prevent contractions in credit available to the private sector and have produced only minuscule increases in the money supply2.

Koo warns that if governments try to reduce their deficits too soon or too fast, they will aggravate the balance sheet recession and cause further damage to the economy. He cites the examples of Japan in 1997 and 2001, when premature fiscal tightening led to deeper recessions and higher public debt ratios. He also criticizes the austerity policies imposed on some European countries, such as Greece, Spain, and Portugal, which have suffered from severe balance sheet recessions and high unemployment.

More recently, Koo has claimed that China is also in a balance sheet recession, as its private sector has been deleveraging since 2016 after a massive credit expansion and investment boom3. He argues that China’s economic slowdown is not due to trade tensions or structural reforms, but to the private sector’s shift from maximizing profits to minimizing debt. He suggests that China should adopt fiscal stimulus measures to support domestic demand and avoid deflation.

A balance sheet recession is a serious challenge for any economy, as it can lead to long-term stagnation and social unrest. It requires unconventional policies that go beyond monetary easing and address the root cause of the problem: excessive private sector debt. By understanding the concept of balance sheet recession and learning from the experiences of Japan and other countries, we can better cope with this phenomenon and avoid its worst consequences.

Book Review: The Millionaire Next Door: The Surprising Secrets of America's Wealthy

 "The Millionaire Next Door" is a must-read for anyone looking to understand the true nature of wealth and success. The book takes a deep dive into the habits and characteristics of America's wealthiest individuals, and what sets them apart from those who struggle to make ends meet. One of the biggest takeaways from the book is that wealth is not necessarily correlated with a high income. Instead, it's often a result of consistent savings, frugal spending habits, and smart investments. The authors bust several popular myths about the wealthy, including the idea that they all inherit their money or that they live extravagant lifestyles. I found the book to be incredibly eye-opening, and it has forever changed the way I think about money.

The authors surveyed and studied thousands of individuals, and their findings are presented in a clear and easy-to-understand manner. On...

How Collusion Affects the Economy: A Guide for Savvy Consumers

To Collude, or Not to Collude: The Economics Behind Collusion Explained Collusion is a term that often has negative connotations in the business world. It refers to a secret or illegal agreement between two or more firms to coordinate their actions in order to gain an unfair advantage over their competitors. Collusion can take many forms, such as fixing prices, dividing markets, limiting output, or sharing confidential information. Collusion can also occur at different levels of the supply chain, such as between suppliers and retailers, or between buyers and sellers. But why do firms collude in the first place? And what are the consequences of collusion for consumers, producers, and society as a whole? In this blog post, we will explore the economics behind collusion and its pros and cons. The Incentive to Collude The main reason why firms collude is to increase their profits by reducing competition and increasing their market power. By colluding, firms can act as if they were a monopo...

How to Avoid the Correlation-Causation Fallacy in Finance: A Quick Guide

  # Correlation Does Not Imply Causation: A One Minute Perspective on Correlation vs. Causation If you are interested in finance, you have probably encountered many graphs, charts, and statistics that show the relationship between two variables. For example, you might see a graph that shows how the stock market performance is correlated with the unemployment rate, or how the inflation rate is correlated with the consumer price index. But what do these correlations mean? And can we use them to make predictions or draw conclusions about the causes of financial phenomena? ## What is correlation? Correlation is a measure of how closely two variables move together. It ranges from -1 to 1, where -1 means that the variables move in opposite directions, 0 means that there is no relationship, and 1 means that the variables move in the same direction. For example, if the correlation between the stock market and the unemployment rate is -0.8, it means that when the stock market goes up, the u...
