Why Currency Value Rather Than Money Supply Drives Inflation

Why Currency Value Rather Than Money Supply Drives Inflation

In this discussion, we explore the intricate mechanics of monetary policy and the historical evolution of currency value with an expert who has spent decades analyzing the intersection of strategic management and economic stability. While traditional economic education often links inflation strictly to the expansion of the money supply, this conversation challenges that narrative by examining how currencies can lose significant purchasing power even when the quantity of money remains stable. We delve into the failures of fixed-supply models like Bitcoin, the intentional devaluations of the 20th century, and the “ratcheting effect” that prevents modern fiat currencies from ever recovering their lost strength.

Traditional theories often equate inflation with the expansion of the money supply, yet currency value can decline even when the supply remains fixed. How should we distinguish between a change in the quantity of money and a decline in its value? What metrics best reflect this distinction?

To truly understand monetary health, we must stop looking solely at how many dollars are in circulation and start looking at what a single dollar is actually worth. Historically, we have seen instances like the period between 1775 and 1900 where the U.S. money supply increased by 160 times, yet the value remained perfectly stable because it was pegged to gold. The best metric for this distinction is a neutral benchmark, typically gold, which has served as a constant measure of value for centuries. When the price of gold rises from $20.67 to $35 or $1,200, it isn’t the gold becoming more “expensive”; it is the currency unit losing its fundamental weight and utility.

Bitcoin was designed with a fixed supply to ensure stability, yet its value has fluctuated wildly for over a decade. Why does a rigid supply fail to produce a stable monetary unit? What specific factors cause a currency to lose its utility as a practical medium of exchange?

The Bitcoin experiment has effectively proven that the quantity theory of money—the idea that a stable supply equals stable value—is fundamentally flawed. Even with a predictable, fixed growth rate, Bitcoin’s value has swung violently, making it impossible to use for long-term contracts or basic daily commerce. A currency loses its utility when it becomes a speculative asset rather than a stable yardstick; if you don’t know what your money will buy tomorrow, you cannot use it to coordinate a complex economy. True monetary stability requires the flexibility to meet the economy’s demand for liquidity while maintaining a fixed value against a trusted benchmark.

In 1933, the dollar’s value against gold dropped by over 40% despite no significant increase in the money supply or “printing.” What were the primary macroeconomic goals behind this intentional devaluation? How did this shift demonstrate that inflation can be a tool of policy rather than a result of finance?

The 1933 devaluation, where the dollar fell from 1505 milligrams of gold to just 889 milligrams, was a calculated move by the Roosevelt Administration to manipulate the macroeconomy. There was no “money printing” involved in the sense of funding a deficit; instead, the goal was to artificially push commodity prices higher to alleviate the pressures of the Great Depression. This era proved that a government can simply decide to make its currency less valuable to achieve a specific policy outcome, such as easing debt burdens or changing trade balances. It was a clear demonstration that “monetary inflation” is often a deliberate choice by policymakers who believe they can manage a nation’s prosperity by tinkering with the unit of account.

During the 1970s, the dollar lost 90% of its value against gold while the Federal Reserve maintained relatively low money supply growth. How does the abandonment of a gold-linked benchmark lead to such a massive collapse in purchasing power? What are the social and economic consequences of this instability?

When the United States severed the link to gold at $35 an ounce, the dollar became a floating entity with no anchor, leading to a decade of “destructive chaos” where its value eventually plummeted to the point that it took $350 to buy that same ounce. This collapse happened even though base money growth remained in the single digits, similar to the stable 1960s. The social consequences were devastating, as the price of oil surged from $3 to $20 a barrel, eroding the savings of ordinary citizens and creating a volatile environment where long-term planning became impossible. Without a fixed benchmark, the currency is subject to the whims of market sentiment and “unintentional accidents” that punish those who hold cash.

Floating fiat currencies often experience a “ratcheting effect” where values decline but rarely recover their original strength. How does this cycle impact long-term debt burdens and unemployment? What specific mechanisms could a central bank use to prioritize value stability over quantity management?

The “ratcheting effect” occurs because central banks find a declining currency value “comfortable”—it feels like a temporary boost, even if it is ultimately harmful—while an increasing value is seen as harsh and recessionary. When a currency gains value, debts become more difficult to pay back and unemployment often rises, so central banks rarely take the “hawkish” steps needed to restore a currency to its former strength. To fix this, a central bank must move away from managing the “quantity” of money and instead focus on a “price rule” or a fixed benchmark. By committing to maintain the currency at a specific weight of gold, the bank subordinates supply to the market’s demand, ensuring that the value remains the constant priority.

High government debt and persistent deficits are often cited as precursors to currency devaluation. What historical precedents suggest that governments might devalue their currency to manage unsustainable debt? What steps must be taken to implement a fixed benchmark before a total currency collapse occurs?

Historically, when governments face mountains of debt they cannot repay through taxation, they often resort to devaluing the currency to “shrink” the debt to dust. We are seeing a modern version of this today; even with the Federal Reserve taking a relatively responsible stance and reducing the base money supply since 2021, the dollar has still fallen significantly against gold. To prevent a total collapse, a government must show the political will to fix the currency to a benchmark like gold before the market forces a devaluation. This requires a transition from the “pure destructive chaos” of floating rates to a system where the value of the monetary unit is treated as an immutable law rather than a policy lever.

What is your forecast for the future of global fiat currencies in relation to gold?

I believe we are heading toward a period where the persistent debt and deficit problems of global governments will lead to further significant declines in fiat currency values. Governments today seem unwilling to fix their monetary systems until they have effectively devalued away their existing obligations. Consequently, my forecast is that the value of the dollar and other major currencies will continue to fall against gold until the resulting economic instability becomes so unbearable that we are forced to return to a gold-fixed benchmark to restore order.
