The Unprecedented Rise of US National Debt
The United States national debt has reached a staggering milestone, officially surpassing the $38 trillion mark in early November. This monumental figure, as reported by the U.S. Treasury’s Debt to the Penny dataset, stood at approximately $38.118 trillion as of November 6. The pace of this increase is truly remarkable, with the debt surging by roughly $1.1 trillion since mid-August alone. The $37 trillion threshold only made headlines a few short months prior, illustrating a relentless expansion of public liabilities.
While traditional economic indicators often frame this growth in dollars, a fascinating and increasingly relevant perspective emerges when we view this colossal sum through the lens of Bitcoin. This approach, which compares the rapidly expanding national debt against a finite, transparent asset, offers a unique insight into the scale of America's fiscal trajectory.
The Bitcoin Lens: A Striking Comparison
Using Bitcoin as a unit of account, financial analyst Sani from TimechainIndex calculated that, at a working price of $103,500 per BTC, the current U.S. public debt equates to approximately 368.3 million BTC. This figure is derived by simply dividing the $38.118 trillion debt by Bitcoin's price. This comparison is not a claim that the U.S. would ever repay its obligations in Bitcoin, but rather an analytical tool to highlight the stark contrast between a fixed-supply asset and a continuously expanding liability.
What makes this perspective particularly compelling is the rapid increase in the debt's Bitcoin equivalent over a relatively short period. Since January 20th of this year, the national debt has grown by an estimated $1.9 trillion. Valuing this specific increase at $103,500 per BTC reveals an addition of roughly 18.36 million BTC to the national ledger. This is where the comparison becomes truly astounding.
"The unit-of-account lens revealed a larger move in debt than in price at the start of the week, underscoring the relentless growth of national liabilities."
To put 18.36 million BTC into context, consider Bitcoin's post-halving issuance rate, which is approximately 450 BTC per day, or about 164,250 BTC per year. This means that the increase in U.S. national debt over just ten months of this year alone is equivalent to more than a century's worth of new Bitcoin supply. This stark comparison vividly illustrates the immense scale of government borrowing when juxtaposed against the unyielding scarcity of Bitcoin.
Bitcoin's Price: A Variable in the Equation
The total Bitcoin equivalent of the debt is, naturally, sensitive to Bitcoin's price. As the price of Bitcoin fluctuates, so does the number of BTC needed to represent the $38.118 trillion debt. A higher Bitcoin price would mean fewer BTC are required to express the national debt, while a lower price would require more. For instance, if Bitcoin were to trade at $200,000, the debt stock would still equate to about 190.6 million BTC. Even at this elevated price, the total still represents an order of magnitude above today’s circulating supply of roughly 19 to 20 million coins.
Here's a snapshot of how Bitcoin's price impacts the debt equivalent:
- $80,000 per BTC: ~476.5 million BTC
- $100,000 per BTC: ~381.2 million BTC
- $103,500 per BTC: ~368.3 million BTC (current calculation basis)
- $120,000 per BTC: ~317.7 million BTC
- $150,000 per BTC: ~254.1 million BTC
- $200,000 per BTC: ~190.6 million BTC
A practical observation at current levels suggests that a $10,000 movement in Bitcoin's price can shift the 'debt in BTC' figure by approximately 32 to 36 million BTC, representing a substantial 9-10% change that is non-linear across the curve.
The Dynamics Influencing the Debt-to-Bitcoin Ratio
The path of this ratio, whether it bends lower or continues to climb, depends on a complex interplay of fiscal policy and market dynamics for Bitcoin.
On the Debt Side (Numerator):
- Treasury's Borrowing Needs: The U.S. Treasury continues to raise significant new cash through quarterly refundings. In November, for example, the Treasury announced $125 billion of issuance, refunding $98.2 billion coming due and raising an additional $26.8 billion in new cash.
- Interest Costs: Rising interest rates directly increase the cost of servicing the national debt, further contributing to its growth. Projections from the Congressional Budget Office (CBO) indicate that net interest costs could climb towards 4% of GDP by 2035.
- Maturity Schedule: A significant portion of marketable debt, around 31%, matures within 12 months, requiring constant refinancing and adding pressure to issuance.
On the Bitcoin Side (Denominator):
- Spot ETF Flows: The emergence of U.S. spot Bitcoin ETFs has introduced a new dynamic. Sustained positive flows into these ETFs would support spot demand for Bitcoin, potentially pushing its price higher and mechanically reducing the 'debt in BTC' ratio. However, week-to-week swings in ETF flows remain common.
- Fixed Supply: Bitcoin's predictable and limited supply mechanism, particularly post-halving, acts as a stark contrast to the government's ability to issue debt. While Bitcoin's on-chain supply inches higher predictably, the debt numerator can add hundreds of billions within weeks.
The macro overlay from budget projections paints a challenging picture. The CBO's 2025 to 2035 outlook anticipates debt held by the public to reach around 156% of GDP by 2055 if current policies remain unchanged. With near-term real economic growth projected under 2% and inflation drifting towards 2%, the nominal GDP denominator lacks a strong boost, reinforcing the arithmetic of a steady or higher 'debt in BTC' reading unless Bitcoin's price significantly appreciates or deficits are substantially compressed.
A Powerful Unit of Account
The comparison of U.S. national debt to Bitcoin serves as a powerful analytical framework, offering a unique perspective on fiscal sustainability and the inherent scarcity of certain assets in an era of expanding government liabilities. It highlights the vast differences in supply mechanics between fiat currencies, which can be expanded through debt issuance, and a digitally scarce asset like Bitcoin.
As we move forward, market participants and policymakers will be watching several key indicators: the Treasury's auction mix, changes in net new cash targets, the evolution of Bitcoin ETF flows, and subsequent CBO updates as budget debates continue. A significant shift in any of these inputs will inevitably impact either the numerator (the debt) or the denominator (Bitcoin's value), constantly reshaping this telling ratio.
The simple math highlights how a fixed-supply asset interacts with a rising liability, providing an unparalleled view into the scale of modern fiscal challenges.
