What Is Hyperdeflation?
Let me explain hyperdeflation directly to you: it's an extremely large and relatively quick level of deflation in an economy.
Key Takeaways
- Hyperdeflation refers to extremely large decreases in the general prices of goods in an economy—or, correspondingly large increases in a money's purchasing power.
- Hyperdeflation is very rare, with perhaps the only example being Bitcoin's quick and meteoric rise in price in a short span of time.
- Hyperinflation is the opposite theoretical concept and is rare, but there have been several cases where the prices of goods have increased rapidly as the value of the currency plummets.
Understanding Hyperdeflation
You need to understand that hyperdeflation occurs when the purchasing power of currency rises drastically in a relatively short period of time. This increase results in debts being more pronounced, as the real value of goods and services increases and the value of the currency falls.
If hyperdeflation were to occur, it would have severe economic consequences as people would forgo making a purchase today when they know it will be much cheaper to buy it tomorrow, or the day after, or the day after—and so spending and investment will grind to a halt.
Hyperdeflation is quite rare and can be contrasted with the still rare but more common periods of hyperinflation, where prices rise rapidly as the purchasing power of currency falls steeply.
I see hyperdeflation as more or less a theoretical term, and there is no exact measure of the difference between it and deflation. However, hyperdeflation, like deflation, can lead to a deflationary spiral in which a deflationary environment leads to lower production, lower wages and lower demand, and thus lower price levels. This scenario creates a feedback loop that continues until an outside force (the government, for example) steps in.
The United States has experienced severe periods of deflation following the Civil War and World War I. Some economists believe that the financial crisis of 2007-2009 brought on a period of deflation in the United States. Japan entered a severe period of deflation that has been ongoing since the 1990s.
Deflationary Spiral
While hyperdeflation is rare, deflation by itself can lead to pernicious negative feedback loops. A deflationary spiral is a downward price reaction to an economic crisis leading to lower production, lower wages, decreased demand, and still lower prices. These events often occur during a period of severe economic crisis, such as the Great Depression.
Deflation occurs when general price levels decline, as opposed to inflation which is when general price levels rise. When deflation occurs, central banks and monetary authorities can enact expansionary monetary policies to spur demand and economic growth.
If monetary policy efforts fail, however, due to greater-than-anticipated weakness in the economy or because target interest rates are already zero or close to zero, a deflationary spiral may occur even with an expansionary monetary policy in place. Such a spiral amounts to a vicious circle, where a chain of events reinforces an initial problem.
Example of Hyperdeflation
Unlike hyperinflation, there are scant few documented real-world examples of hyperdeflation in history. Recently, however, the world has seen the emergence of cryptocurrency: a decentralized digital currency that works through a blockchain, or public transaction ledger.
Bitcoin, created in 2009, was the first digital currency and remains the most well-known. Many observers have labeled its recent volatility as an unprecedented example of hyperdeflation. Some cryptocurrency experts and economists label its rising prices as a bubble, noting that the currency has long-term prospects. However, they also point out the possibility that deflation will occur.
By design, the number of new coins decreases each year, but demand for Bitcoin is growing. This dynamic may lead to the digital economy entering a deflationary period. Since no centralized banking system or Federal Reserve equivalent oversees the currency, no intervention policies will be set into motion.
Furthermore, Bitcoin cannot be dropped and picked up by a fortunate passerby; if one loses their personal key, they lose the money, and the money is effectively pulled out of circulation. Additionally, there is a high level of wealth concentration among Bitcoin holders, meaning there is a relatively small number of users who can sell or, more importantly to this scenario, not sell.
With rising value comes more incentive to buy and hoard Bitcoin, which only increases the price and further decreases supply. This situation could hypothetically lead to a real-world occurrence of hyperdeflation.
