In early September 2026, Bitwise Investments released a study that challenges the long‑standing narrative of Bitcoin as a "digital gold". The analysis shows that Bitcoin reacts less to shifts in 10‑year Treasury yields than gold does, while the two assets have tightened their correlation in recent months.

The study was sparked by the U.S. Treasury’s August 19 announcement that it would double the size of its liquidity‑support buyback program for long‑dated nominal coupon securities. The program, previously buying $2 billion of bonds per operation, was expanded to at least $4 billion and set to launch on September 9. In the week that followed, Bitcoin’s price surged 22.4 %—the largest weekly gain since March 2024—whereas gold climbed only about 5 %.

Historically, Bitcoin’s correlation with 10‑year Treasury yields has been lower than that of gold. When Treasury yields rise and bond prices fall, gold tends to move more sharply than Bitcoin. Bitwise attributes this disparity to how each asset is positioned in institutional portfolios. Gold is a staple hedge in fixed‑income allocation models that adjust exposure in response to yield expectations. Bitcoin, not yet a standard component of those models, is held by a more heterogeneous group—including retail holders, crypto‑native funds, corporate treasuries, and sovereign wealth funds—who are still building positions rather than rebalancing around the yield curve.

Supply dynamics also play a role. Gold production can, albeit slowly, respond to price signals, whereas Bitcoin’s issuance schedule is fixed by its protocol and does not change in response to Treasury actions or Federal Reserve policy.

The relationship between Bitcoin and gold has shifted noticeably. Bitwise reports that the 90‑day rolling correlation between the two assets exceeded 0.5 as of August 31 2026—the highest level since 2020. Earlier in the year, the same correlation hovered near zero, according to Grayscale research published on August 27. The rapid swing suggests that macro forces, particularly rising long‑term Treasury yields and concerns about fiscal sustainability, are pulling both assets in the same direction.

For portfolio managers, the findings raise questions about diversification. If Bitcoin and gold are increasingly exposed to the same macro risks, but Bitcoin remains less sensitive to Treasury yields, the optimal allocation could shift toward crypto. For traders, the pattern offers a tactical playbook: Treasury selloffs—especially those triggered by fiscal policy announcements or debt‑ceiling debates—have historically been followed by outsized Bitcoin moves. The 22.4 % weekly gain after the buyback expansion is the most dramatic recent example.

However, the Bitcoin‑gold correlation is volatile. The study cautions that if the 90‑day correlation falls back toward zero, the diversification benefits of holding both assets together could diminish.

The U.S. Treasury’s debt level provides additional context. In August 2026, gross federal debt surpassed $40 trillion, reaching approximately $40.13 trillion by mid‑month. Rising debt levels and higher long‑term yields have intensified scrutiny of Treasury operations and their impact on financial markets.

In summary, Bitwise’s analysis indicates that Bitcoin’s lower sensitivity to Treasury yields and its growing correlation with gold are reshaping how the asset is viewed relative to traditional safe‑haven instruments. The dynamics suggest that Bitcoin may offer a more resilient hedge during bond‑market stress, but the evolving relationship with gold means that investors should monitor correlation metrics closely as they adjust portfolios.
