Morne Patterson — Why Central Banks Are Scared of Deflation

Deflation, defined as a prolonged decline in the prices of goods and services, signals more than just a drop in economic indicators; it embodies a complex threat to economic stability. With an inflation rate dipping below 0%, this phenomenon triggers concerns about unemployment, recession, and fluctuating interest rates that merit a closer analysis. Central banks stand on the frontline, facing the task of combating deflation and its spiraling impact on economies worldwide, which underscores why central banks are scared of deflation.

This article considers the roots and repercussions of deflation, from historical episodes to present challenges, underscoring the critical fear it instills in central banks. By exploring the causes of deflation, its effect on economies through unemployment, recession, and interest rates, and the strategies adopted by central banks to mitigate these effects, readers will gain comprehensive insights into the ongoing struggle against an economic downturn. Through an in-depth analysis, this discussion aims to shed light on the multifaceted relationship between deflation, economic policy, and global financial health.

Understanding Deflation

Deflation, often perceived as a decrease in the general price levels of goods and services, emerges from various economic conditions. Central to understanding deflation are its causes and measurement techniques:

· Causes of Deflation:

1. Decrease in Money Supply: A contraction in the overall money available within an economy.

2. Decline in Consumer Demand: When spending by consumers drops significantly.

3. Increase in Business Productivity: Technological advancements or operational efficiencies that reduce production costs.

· Measurement Using the Consumer Price Index (CPI):

· The CPI tracks around 80,000 items monthly, encompassing:

· Food and Beverages

· Housing (Rents)

· Clothing

· Medical Care

· Transportation (Including Fuel Costs)

· Recreation

· Education and Communication

· Other Goods and Services

Deflation’s impact on the economy initiates a vicious cycle, starting with reduced consumer spending leading to business cutbacks and layoffs. This results in heightened unemployment, further diminishing spending and increasing defaults. The complexity of deflation is further underscored by its relationship with monetary policies and the exchange rate regime. Core countries with financial maturity can often float their currencies to mitigate deflation’s effects, whereas periphery countries may struggle, facing the full impact.

The Fear of Deflation: Historical and Current Perspectives

Deflation, often misunderstood, carries a historical weight that shapes the fears of central banks today. The gold standard, historically linked to the Great Depression, exemplifies the dangers of rigid monetary systems. Central banks worry about deflation because:

· Historical Lessons:

· The Great Depression highlighted the gold standard’s limitations, where currency value directly linked to gold restricted monetary policy flexibility.

· Deflation during this period was not typical but showcased the severe impact of policy missteps under rigid systems.

· Economic Indicators:

· Signals of a stagnating economy, leading to high unemployment and unaffordable debt repayment.

· Businesses face grim outcomes, further exacerbating economic downturns.

“The Fear of Deflation: Historical and Current Perspectives” considers deflation’s nature, as seen in “Deflation: Current and Historical Perspectives.” This book dissects deflation across four parts, examining its relationship with monetary policy, asset prices, and international perspectives. It distinguishes between ‘good’ deflation, driven by positive supply shocks, and ‘bad’ deflation, resulting from negative demand shocks or policy errors. This nuanced understanding challenges the view of deflation as inherently negative, suggesting that outcomes depend significantly on the context and policy responses.

Causes of Deflation

Deflation, a complex economic phenomenon, can be attributed to various factors categorised primarily under two major umbrellas: a decrease in aggregate demand and an increase in aggregate supply.

· Decrease in Aggregate Demand

1. Tighter Monetary Policy: Central banks may opt for a tighter monetary policy, leading to a decline in the money supply. This action often results in higher interest rates, encouraging savings over spending.

2. Reduced Government Spending: A significant cutback in government expenditure can lead to a decrease in overall demand.

3. Consumer Behavior: An increase in consumer savings or a decline in consumer confidence, often due to stock market downturns, can reduce overall spending.

4. Stock Market Failures: Events causing stock market downturns directly impact consumer and business confidence, leading to reduced spending and investment.

· Increase in Aggregate Supply

1. Technological Advancements: Improvements in technology enhance production efficiency, leading to lower costs and, consequently, lower prices.

2. Decrease in Production Costs: A fall in the prices of key production inputs can lead to increased production. When this increase outpaces demand, it contributes to deflation.

3. Oversupply: An oversupply in the market, whether due to increased production capabilities or reduced consumption, pushes prices down.

Understanding these causes helps in identifying the nature of deflation, emphasising the need for a balanced approach in policy formulation to mitigate its effects.

The Impact of Deflation on Economies

Deflation, while often seen through a lens of negativity due to its potential to exacerbate economic crises, carries a dual nature that impacts economies in varied ways.

· Economic Consequences of Deflation:

1. Spiral of Decreased Spending: As prices fall, the anticipation of further declines leads businesses and individuals to postpone spending and investment. This causes a reduction in demand, initiating a deflationary spiral that can deepen a recession.

2. Financial Distress and Market Instability: Deflation can lead to financial distress by exacerbating asset price fluctuations, contributing to macroeconomic instability. A collapse in market liquidity poses severe consequences for asset markets and the broader economy.

3. Employment and Income Effects: The phenomenon often results in falling incomes and higher unemployment rates, as businesses cut back on expenses, including labor. This, in turn, leads to less consumer spending and the exacerbation of debt burdens.

· Positive Aspects and Mitigating Factors:

1. Technological Progress and Living Standards: In some instances, deflation reflects technological advancements, leading to increased abundance and improved standards of living. This aspect of deflation can be beneficial, promoting greater efficiency and competition.

2. Historical Perspectives: Not all deflationary periods have led to negative outcomes. For instance, Switzerland’s economy experienced deflation without significant adverse impacts, challenging traditional views on the subject.

3. Asset and Housing Price Deflations: While consumer goods and services price deflation has shown a weak or insignificant relationship with output growth, asset and housing price deflations have proven to be more economically damaging.

Understanding the impact of deflation on economies requires a nuanced approach, acknowledging both its potential harms and benefits. Economists continue to debate the optimal response to deflation, especially when it results in economic loss, underscoring the complexity of this economic phenomenon.

Methods Used by Central Banks to Combat Deflation

Central banks have developed various approaches to combat deflation, leveraging both monetary and fiscal policy tools. These strategies are designed to stimulate economic activity, increase aggregate demand, and ultimately raise price levels. Below is an overview of the key methods:

· Monetary Policy Tools:

1. Quantitative Easing (QE): Central banks create new money to buy shares, increasing liquidity and encouraging lending and investment.

2. Lowering Interest Rates: Reduces borrowing costs for businesses and consumers, encouraging spending and investment.

3. Open Market Operations (OMO): Buying and selling government securities to control the money supply.

4. Negative Interest Rates: Charging banks for holding reserves to encourage lending rather than hoarding cash.

· Fiscal Policy Tools:

1. Increasing Government Spending: Injects money directly into the economy, boosting demand for goods and services.

2. Cutting Tax Rates: Leaves more money in the hands of consumers and businesses, encouraging spending and investment.

· Notable Implementations:

· The Federal Reserve’s use of QE following the 2008 financial crisis.

· The European Central Bank’s QE program launched in 2015.

· Japan’s “Abenomics” policy framework initiated in 2012.

These tools, while effective in staving off deflation, require careful management to avoid potential side effects such as hyperinflation or asset bubbles.


By understanding the cause of deflation, ranging from decreased aggregate demand to technological advancements, and assessing its pervasive effects on economies through unemployment, recessions, and interest rates, we have highlighted the dynamics that make deflation a force to reckon with. This emphasises the important role of central banks in employing strategies such as monetary and fiscal policies to counter this economic issue.

Conclusively, while the battle against deflation poses a significant challenge, it also opens up opportunities for central banks to innovate and adapt their economic frameworks to ensure stability and growth. The significance of these findings suggests that a nuanced understanding and response to deflation could potentially mitigate its adverse impacts. As we move forward, it is clear that the vigilance and adaptability of central banks will be paramount in navigating the unpredictable terrains of economic fluctuations, reinforcing the importance of continuous research and policy evolution in the face of deflation.


1. What makes inflation a concern for central banks?Central banks are primarily worried about inflation because it can lead to unstable inflation dynamics, such as the de-anchoring of inflation expectations and salary spirals. However, these concerns are not typically reflected in the standard New Keynesian theoretical framework that guides monetary policy.

2. Why is preventing deflation a key objective for central banks?Preventing deflation is critical for central banks because deflation can create a harmful cycle that depresses spending and investment. This cycle can then result in lower economic growth and increased unemployment.

3. How does deflation pose a threat to the economy?Deflation, which is characterised by a general decrease in the prices of goods and services, signals an economy in stagnation. It can lead to severe consequences such as high unemployment, difficulties in repaying debt, and negative impacts on businesses.

4. Why do central banks pay close attention to inflation expectations?Central banks monitor inflation expectations closely because these expectations can significantly influence the spending behaviors of businesses and consumers. Ultimately, these behaviors have a direct impact on the economy’s overall stability.
