Why Bitcoin Reacts More to Macro Than It Did Before 2020

Bitcoin’s latest reaction to rising Treasury yields fits a pattern that researchers have tracked since 2020.

Bitcoin traded below $84,000 on September 24 as US government bond yields reached multi-decade highs. The 10-year Treasury yield touched 5.145%, while the 30-year yield moved above 5.44%, its highest level since 2004. Strong US economic data and higher energy prices also pushed markets to increase expectations for further Federal Reserve tightening.

Bitcoin traded near $83,300 during the session after giving back part of its September rally. The price move occurred alongside weakness in other risk assets as bond yields rose.

Academic research suggests this kind of immediate macro reaction was far less consistent during Bitcoin’s earlier years.

Bitcoin Did Not Always React Immediately to the Fed

Sören Karau’s 2023 study in the Journal of International Money and Finance examined high-frequency Bitcoin prices around US monetary policy announcements.

The study found that Bitcoin did not show a systematic immediate response to Federal Reserve announcements for much of its history. That changed in late 2020, when price movements around FOMC decisions became more pronounced.

Karau also found that realized Bitcoin volatility around narrow FOMC announcement windows increased after the COVID-19 shock.

After 2020, unexpected US monetary tightening produced an immediate Bitcoin response that increasingly resembled other risk assets. Bitcoin prices generally fell after tighter policy surprises.

The earlier relationship looked different. Karau’s longer-horizon analysis found that before 2018, US tightening could be followed by higher Bitcoin prices rather than lower ones. The paper linked some of that historical demand to economies facing capital controls, particularly in East Asia.

That means Bitcoin’s current macro sensitivity is not simply a stronger version of its old behavior. The response’s direction and timing also changed.

Crypto Became More Connected to Traditional Markets

Meanwhile, the broader crypto market also became more closely linked with equities after 2020. An International Monetary Fund study found that Bitcoin showed relatively little correlation with major equity indices during 2017 through 2019.

That relationship changed after the second quarter of 2020, when Bitcoin and US stocks increasingly moved together as global financial conditions eased and investor risk appetite strengthened.

The IMF measured a sharp increase in cross-market spillovers. Volatility spillovers from the S&P 500 to Bitcoin rose by roughly 13 to 15 percentage points between 2017–2019 and 2020–2021. Return spillovers from equities to Bitcoin also increased materially.

Another IMF paper on the crypto cycle found that Bitcoin’s correlation with the S&P 500 became positive and statistically significant only after 2020.

That study also found that the share of institutional investors helped explain the stronger relationship between crypto and equities. The authors said rising participation by investors active in both markets created a clearer transmission channel between them.

Institutional Participation Changed the Market Structure

Bitcoin’s investor base expanded substantially during and after the 2020 period. Traditional asset managers, public companies, and professional trading firms gained more direct exposure to the market.

That development increased the number of participants who evaluate Bitcoin alongside stocks, bonds, and other portfolio assets.

Research from S&P Global found that Bitcoin’s daily correlation with the S&P 500 increased to about 0.38 from 2020 onward, compared with roughly 0.14 over its broader sample beginning in 2014.

The firm also recorded a stronger negative relationship between Bitcoin returns and changes in market volatility after 2020.

Those findings support the view that Bitcoin increasingly trades within the same risk-allocation framework used for traditional assets, although correlations still vary through time.

Sources covering June 2020 through March 2026 put Bitcoin’s daily correlation with the S&P 500 at 0.375. That relationship became much stronger during several equity corrections.

Inflation Does Not Produce One Consistent Bitcoin Reaction

Bitcoin’s fixed supply has often supported comparisons with inflation hedges, but empirical results show a more complicated relationship. Research found that Bitcoin became more sensitive to US inflation releases after 2020.

However, positive inflation surprises did not consistently lift Bitcoin. Instead, Bitcoin often moved in the same direction as risk assets when inflation data increased expectations for tighter monetary policy.

Marcin Pietrzak reached a similar conclusion using Federal Reserve and European Central Bank monetary surprises.

His research found that Bitcoin responds systematically to central-bank information, but the size and direction of that reaction changed over time. The study found little support for treating Bitcoin as a stable inflation hedge across all periods.

Notably, this distinction matters when inflation rises. Higher inflation can support the scarcity argument around Bitcoin, but it can also push central banks toward higher rates. The resulting increase in bond yields and financing costs can reduce demand for risk assets.

The Current Market Shows the Post-2020 Pattern

Even so, the present macro environment provides another example of the newer relationship. The Federal Reserve raised its policy rate by 25 basis points on September 16 to 3.75%–4.00%, citing elevated inflation.

Days later, Treasury yields moved sharply higher as strong economic data and rising energy prices increased expectations for further tightening.

Bitcoin fell alongside the broader risk-off move. That single session does not prove that rates alone caused the decline. Bitcoin also responds to crypto-specific flows, leverage, regulation, and market positioning.

However, the reaction matches the post-2020 pattern identified across several studies: Bitcoin now responds more quickly to monetary policy, inflation surprises, bond yields, and broader shifts in global risk appetite than it generally did during its earlier market history.
