When prices spiral down: Understanding the truth about Deflation

Deflation is coming, seemingly Favourable Information but hiding risks.

Many people feel joy when they first hear about deflation - falling prices mean that the same amount of money can buy more things. However, economists tend to be wary of prolonged deflation. Why is that? Because this seemingly favorable situation, once out of control, could lead to a wave of unemployment, economic stagnation, or even a debt crisis.

Japan's long-term deflation over the past thirty years can be considered a cautionary tale. While the continuous decline in prices has increased consumer purchasing power, it has also led to a decrease in corporate investment willingness and a shrinkage of job opportunities. This is why central banks around the world have set their targets at around 2% annual inflation rate—stable but moderate inflation is seen as a sign of a healthy economy.

What is deflation? Why does it occur?

Deflation refers to the general decline in prices of goods and services in an economy. This is the opposite of inflation (price rise) and directly increases the purchasing power of money. Sounds good, but the problem is: Under what circumstances can deflation turn into an economic meat grinder?

Deflation is usually triggered by three main factors:

Total demand sharply contracts: When consumers and businesses tighten their wallets at the same time, overall purchasing power declines, leading to a sharp decrease in demand for goods and a natural decline in prices.

Oversupply: When a company's production capacity surpasses market demand, especially after new technologies significantly reduce production costs, intensified competition leads to price wars. This is particularly evident in the internet and technology sectors.

Currency Appreciation Effect: When a country's currency is relatively strong, imported goods become cheaper, while domestic exported goods become relatively expensive, leading to a decrease in overseas demand, ultimately driving down domestic prices.

Deflation vs Inflation: The Duel of Two Economic Ailments

Both phenomena will distort the economy, but the mechanisms are completely different.

During deflation, rational consumers choose to wait—because goods may be cheaper next month. This collective delay in purchasing behavior creates a vicious cycle: declining sales → reduced production by companies → increased layoffs → further shrinkage in demand.

In contrast, although inflation suppresses real wealth, it encourages people to accelerate consumption and investment, maintaining economic vitality.

In the era of deflation, how should the government and central banks act?

In the face of the threat of deflation, economic decision-makers typically resort to two main toolboxes.

Monetary policy is the first line of defense. The central bank stimulates borrowing by lowering interest rates—low rates reduce financing costs for businesses and consumers, promoting investment and consumption. When conventional interest rate cuts become ineffective (interest rates are already close to zero), the central bank resorts to quantitative easing (QE), a powerful tool: injecting a large amount of liquidity directly into the financial market, lowering long-term interest rates, and encouraging funds to flow into the real economy.

Fiscal policy is when the government takes direct action. The government increases spending to stimulate total demand or increases disposable income for residents and businesses through tax cuts. This type of policy can quickly boost short-term demand, but it will also increase government debt.

The combination of two policies is often the most effective - the central bank releases liquidity to create conditions for government spending, and the government's stimulus measures directly drive economic growth.

The Double-Edged Sword of Deflation: Appears Cheap, but is Actually Dangerous

Favourable Information:

• Decrease in cost of living: Prices of goods and services drop, enhancing consumers' actual purchasing power and relatively improving living standards.
• Cost optimization for enterprises: decrease in the price of materials required for production, improvement in profit margins.
• Increased Savings Value: With the appreciation of currency, the purchasing power of savings increases, encouraging people to accumulate wealth.

Hidden Dangers:

• Consumption Trap: Consumers generally postpone purchases to wait for lower prices, leading to a continuous decline in total demand and creating the expectation of “the longer you wait, the cheaper it gets.”
• Debt Snowball: In a deflationary environment, the actual value of existing debt increases, and the repayment pressure on borrowers intensifies, which may trigger a wave of defaults.
• Employment Crisis: Insufficient consumption leads to a decline in corporate revenue. In order to maintain profits, companies have to lay off employees on a large scale, resulting in an increase in the unemployment rate.

Conclusion: Deflation is not a gospel

Deflation may seem to be a good thing on the surface, with falling prices and rising currency value, but prolonged deflation can lead to a quagmire of economic recession. Negative effects such as delayed consumption, increased debt, and rising unemployment will gradually transmit, ultimately harming the entire economy.

This also explains why central banks and governments around the world are wary of deflation—moderate inflation, while eroding savings, can keep the economy vibrant; whereas the seemingly cheap world of deflation is actually freezing the blood circulation of the entire economy.
