Bitcoin has effectively offset its modest inflation with massive gains, while the US Dollar Index (DXY) has risen only 12% nominally, with cumulative inflation eroding 20% of its value. Often regarded as a hedge against inflation, Bitcoin maintains a positive but low inflation rate of 0.83%, especially when compared to the dollar’s peak inflation of 9.1% in 2022. A closer look at the cumulative inflation rates for Bitcoin and the US dollar reveals Bitcoin’s unique ability to preserve wealth.
Between 2020 and 2025, Bitcoin surged approximately 960%, dwarfing the DXY’s nominal increase of just 12%. The inflation-adjusted price of Bitcoin, compared to the DXY normalized for inflation, highlights the stark differences in their real value. While the nominal DXY reflects currency strength relative to others, its inflation-adjusted value reveals the persistent erosion of purchasing power.
Currently, the nominal DXY is at 109.8, indicating strong global demand for the dollar amid ongoing macroeconomic uncertainties. However, when adjusted for cumulative US inflation since 2020—averaging over 2% annually and peaking above 8% in 2022—the DXY’s real value declines to 87.5. This 22.3-point drop represents a 20.3% reduction in real purchasing power, underlining the dollar’s susceptibility to inflation despite its relative global strength.
Conversely, Bitcoin’s nominal price has reached roughly $91,000. Adjusting for its annual inflation rate—1.74% between 2020 and 2024, and 0.83% in 2025—its inflation-adjusted price is approximately $84,365. The $6,635 difference reflects a mere 7.3% reduction in value, showcasing Bitcoin’s resilience and ability to preserve purchasing power over time. Bitcoin’s programmed scarcity and low inflation rate are central to this stability, making it an effective hedge against inflation compared to fiat currencies.
The contrast between the inflation-adjusted metrics of the DXY and Bitcoin underscores a significant narrative. Fiat currencies like the dollar face considerable devaluation due to inflation, while Bitcoin’s controlled supply dynamics solidify its role as a hedge against currency debasement. The pronounced impact of inflation on the DXY highlights the challenge of preserving purchasing power in a fiat system, particularly during periods of elevated inflation.
Understanding the difference between nominal and inflation-adjusted values is crucial for evaluating long-term asset performance. The DXY’s nominal strength masks the ongoing erosion of the dollar’s purchasing power, while Bitcoin’s inflation-adjusted price underscores its long-term value preservation. These comparisons underscore the importance of inflation-adjusted analyses in shaping strategies for navigating macroeconomic trends.
Additionally, the inflation rates of the currencies used in calculating the DXY should also be considered to refine these observations. Nevertheless, the outlined figures provide a robust perspective on Bitcoin’s superior performance against the dollar in real terms.
For instance, a $100 investment in Bitcoin in 2020 would now equate to $927 in real purchasing power. In contrast, $100 invested in the DXY today would only amount to $91 in inflation-adjusted terms, illustrating the stark difference in value retention.
