Introduction

Bitcoin and US government bonds have historically functioned in opposition within the financial ecosystem. While Bitcoin represents a decentralized digital currency, US Treasury bonds are a form of government-backed debt. However, recent findings from Fidelity Digital Assets indicate a shift in how these two assets are behaving in the market.

New Findings from Fidelity Research

On October 15, 2026, Fidelity published a study highlighting a significant increase in the correlation between Bitcoin’s market capitalization and the real yields on 10-year US Treasury bonds. The data reveals that this correlation has surpassed 0.6—a record high that suggests a notable change from their historically negative or negligible relationship.

The term “real” in real yields refers to the returns on bonds after adjusting for inflation, providing a clearer picture of the actual earnings for investors.

Recent Market Trends

Backing up this newfound relationship, Bitcoin experienced a nearly 30% price increase in the two months preceding the report. Concurrently, 10-year Treasury rates saw more than a 10% rise during the same period.

Impact of US Public Finances

Fidelity attributes the altered dynamics between Bitcoin and Treasury yields to macroeconomic factors, notably the increasing strain on US public finances. As of now, US federal debt exceeds $40 trillion, with interest on this debt emerging as the second-largest expense in the federal budget, only surpassed by Medicare expenditures.

Investors, concerned about these fiscal pressures, may be gravitating towards Bitcoin, which has a capped supply of 21 million coins and follows a transparent issuance schedule defined by its underlying code.

Insights from Industry Experts

Chris Kuiper, Fidelity’s Vice President of Research, emphasized this correlation in his remarks on October 1, 2026. He connected rising Treasury yields and Bitcoin price increases to broader investor sentiment regarding the pressures from fiscal deficits and escalating debt levels.

Conclusions and Future Considerations

This emerging correlation between Bitcoin and US Treasury yields may necessitate a reevaluation of portfolio models that previously relied on the inverse relationship of these assets. Investors must consider that this shift could alter how hedging strategies function.

Moreover, the durability of this correlation is yet to be established, as a 0.6 correlation is unprecedented. Monitoring how this relationship withstands changes in fiscal policy, budget talks, and Treasury auctions will be crucial moving forward.

Currently, Fidelity’s analysis suggests that Bitcoin is increasingly seen as a component in discussions surrounding American finances, particularly in light of the growing debt and interest costs that are unlikely to abate soon.
