When it comes to money and currency, two important laws are often discussed—Gresham’s Law and Thier’s Law. While these laws both deal with how money circulates in an economy, they present opposing viewpoints. Understanding these principles is essential for analyzing how different types of currency coexist and how behaviors around money shift. What makes this even more interesting today is the rise of Bitcoin, a digital currency that, while not recognized as legal tender in most countries, seems to defy certain elements of both laws. Let’s delve deeper into both of these laws, understand their interrelationship, and discuss how Bitcoin plays into this economic narrative.
What is Gresham’s Law?
Gresham’s Law states that “bad money drives out good money.” Simply put, when two forms of money are in circulation at the same time—one with intrinsic value and one with less perceived value—the “bad” money (the one with less intrinsic value) will tend to drive out the “good” money (the one with greater perceived value).
Let’s break it down with a classic example:
Imagine an economy where both gold coins and paper notes are accepted as legal tender. The gold coins, backed by their intrinsic value and stability, are regarded as “good” money, while the paper notes are seen as less valuable or even inflation-prone (the “bad” money).
People in this economy, perceiving that the gold coin holds more value, will prefer to hoard the gold and spend the paper notes, even though both are legal forms of payment.
Why? Because paper money doesn’t seem to retain as much long-term value, so people are more motivated to get rid of it (through spending or trading), keeping the gold as a store of value. Gresham’s Law thus describes a behavior where the “bad” money circulates more freely while the “good” money disappears.
What is Thier’s Law?
Thier’s Law is, in a way, a counterpoint to Gresham’s Law. It suggests that “good money drives out bad money,” meaning that over time, better money—whether it’s more stable, more trusted, or more intrinsically valuable—will replace inferior money.
So, when faced with both a stable currency and an inferior one, people will favor the stronger currency. If confidence in the inferior currency (the “bad” money) diminishes or if the economy undergoes reforms, the stronger currency will dominate over time.
For example:
Let’s say a country decides to transition from a paper-based currency system (which suffers from inflation and devaluation) to a gold-backed system. Thier’s Law suggests that people will quickly begin to demand and use the gold-backed currency more, while the unstable paper money will gradually become obsolete or less used.
Importantly, people don’t reject the “bad” money outright in this case—rather, over time, confidence in the inferior currency fades, and people flock to the better form of money, leading to a natural replacement or reduction in the use of the inferior currency.
Do Gresham’s Law and Thier’s Law Contradict Each Other?
At first glance, Gresham’s Law and Thier’s Law seem to contradict each other. Gresham’s Law says bad money drives out good money, while Thier’s Law suggests that good money drives out bad money. However, in reality, these principles aren’t always in direct opposition—they actually apply in different contexts and timeframes.
- Gresham’s Law is more applicable in a situation where both types of money are circulating side by side. The inferior money tends to be spent and widely used while the superior money is hoarded or withdrawn from circulation. This process can happen quickly because people are acting on immediate practical considerations, often involving the desire to protect their wealth.
- Thier’s Law, on the other hand, operates more slowly and describes a longer-term shift in public confidence. It comes into play when an economy moves from a phase where “bad” money is used to one in which a better, more stable form of money takes over. This shift usually happens because of reforms, changing economic conditions, or an evolving loss of confidence in the inferior currency.
In short, Gresham’s Law tends to be a short-term phenomenon, while Thier’s Law relates to a long-term shift. They don’t always apply simultaneously, but their respective impacts depend on how the market perceives the currencies and whether those currencies are in active reform or circulating together.
Bitcoin and the Laws of Money: Does Bitcoin Follow These Laws?
Here’s where it gets really interesting: Bitcoin. Bitcoin is a cryptocurrency with no intrinsic physical value—unlike gold or traditional paper money. As such, it doesn’t qualify as legal tender in most countries and is not backed by any government or central bank. Yet, many people still hoard Bitcoin, rather than spend it.
So, how does Bitcoin fit into these laws?
- According to Gresham’s Law, if Bitcoin were competing alongside some form of bad money (such as inflationary paper currencies) in a given economy, the principle would suggest that people would use the paper money more, hoard Bitcoin, and keep it out of circulation. But Bitcoin is not typically used as transaction money in most places—it’s primarily seen as a store of value or an asset rather than a circulating currency.
- As a result, rather than being spent, Bitcoin is hoarded by investors or treated like digital gold, expected to appreciate in value over time. This hoarding behavior aligns with Gresham’s Law since people avoid spending the “good” money (Bitcoin) and instead use the more readily available “bad” money (fiat currencies).
On the other hand, Thier’s Law doesn’t fully apply to Bitcoin’s situation, at least not in the same way it would to gold-backed money in traditional systems. Bitcoin, by its nature, is not displacing a traditional currency. Instead, it operates in a parallel financial ecosystem. While some Bitcoin advocates argue that it could one day replace “fiat” currencies, this would require a huge shift in global economic behavior, trust in governmental currencies, and perhaps even reforms.
Essentially, Bitcoin’s future as a currency might not be about directly displacing bad money but rather about offering an alternative system to users who lose faith in traditional financial institutions and centralized money.
Bitcoin, Legal Tender, and Economic Change
Bitcoin, while currently not legal tender, still raises important questions about the future of money. As governments explore digital currencies and other alternatives to traditional money, it’s possible that new economic systems might develop where Bitcoin (or other cryptocurrencies) could potentially become a dominant form of money, leading to a scenario where Gresham’s and Thier’s Laws are both at play in entirely new ways.
At present, Bitcoin’s behavior aligns more with Gresham’s Law, where it is viewed as the “good” money that is hoarded rather than spent. Whether it can eventually transition into the “good money” that gradually replaces bad money, as outlined by Thier’s Law, depends on how the public’s confidence in both government-backed currencies and digital assets evolves over time.
Final Thoughts
Gresham’s Law and Thier’s Law offer valuable insights into how different forms of money interact in an economy. While Gresham’s Law often describes short-term behaviors when inferior and superior currencies co-exist, Thier’s Law reflects longer-term economic shifts where better forms of currency push out the worse ones. Bitcoin, with its characteristics as a store of value rather than a currency in daily transactions, provides an interesting case study, showing how people can hoard the “good money” while spending the “bad,” even when Bitcoin is not legal tender. Whether or not it ever transitions into “good money” to displace government-issued currencies remains a fascinating question for the future of global finance.
