Bitcoin’s 50% drawdown since October 2025, against a roughly 12% decline in the Nasdaq, has fuelled talk of decoupling. On the surface, the price divergence is striking. But a closer look at the data tells a more nuanced story.
Bitcoin Amplified Nasdaq Pain – Not Decoupled, Just Unstable
13 April 2026 - 13:30 CEST
Bitcoin did not break away from equities. It behaved as an unstable, at times highly levered transmission of the same macro risk impulses – such as interest rate expectations and broader risk sentiment – driving the Nasdaq. While short-term correlation weakened at times, Bitcoin’s beta periodically surged. Beta measures how much Bitcoin moves relative to the Nasdaq for the same market move, signalling amplified sensitivity rather than independence.
Same signal, different amplitude
The key to understanding this period lies in the relationship between correlation and beta. At several points, the two moved in opposite directions. On 5 Feb, monthly correlation sat at a modest 0.47, hardly indicative of a tight relationship. Yet Bitcoin’s beta was already pushing 1.95, meaning it was reacting to the same underlying moves, but with nearly double the intensity.

By early March, the dynamic became even clearer. Correlation rose to 0.69, while beta surged above 3, turning Bitcoin into a high-volatility proxy for the same macro trade. Correlation tells you whether assets tend to move together. Beta tells you how much they move – in this case, often two to three times as much – when they do. Over this period, Bitcoin consistently showed that even when the relationship looked loose, the underlying exposure remained. The signal was shared. The amplitude was not.
Why it felt like decoupling
The confusion comes from the price path. From 1 October 2025, Bitcoin fell roughly 52% into its February low. The Nasdaq, by contrast, declined just 12%, with its trough arriving much later, on 30 Mar. That gap is large enough to create the impression of separation.

But correlation is not about how far assets move. It is about whether they tend to move in the same direction on a daily basis. Bitcoin could underperform dramatically and still remain tied to the same macro forces if its day-to-day moves increasingly align with equities. That is precisely what the data shows, particularly as the period progressed.
A shifting relationship
What stands out most is how unstable the short-term relationship has been. Monthly correlation dropped as low as 0.15 in early October 2025, before rebounding sharply above 0.80 a month later. It weakened again into January, then recovered into March, before settling around 0.44 in early April.

At times, Bitcoin traded as a more idiosyncratic asset – meaning its price was driven mainly by crypto-specific flows and positioning rather than broader market moves. At others, it snapped back into alignment with equities, often abruptly and with greater volatility. Zoom out, however, and the picture becomes clearer. Quarterly correlation remained consistently elevated throughout, while yearly correlation has steadily rebuilt, reaching 0.50 by early April, its highest level in the post-October 2025 period. Yearly beta has followed a similar path, rising back above 1. Despite the noise, the longer-term linkage has been strengthening.
Where things stand now
In the short term, the relationship has cooled. The sharp decline in monthly beta from early March levels suggests that the phase of Bitcoin acting as a high-beta proxy for equities has normalized. But over longer horizons, the linkage remains intact. Bitcoin continues to behave like a risk asset exposed to the same macro environment as equities, just with amplified moves.
A better way to think about it
The idea of decoupling suggests a binary outcome – either connected or not. That framing no longer holds. The Bitcoin–Nasdaq relationship is now clearly horizon-dependent, meaning it changes depending on the time frame you examine.
On a monthly basis, it is unstable and sensitive to positioning and narrative
Over a quarterly horizon, the macro linkage remains strong
Over a yearly horizon, the relationship is rebuilding
For investors, that leads to a more useful question. At what horizon is Bitcoin trading purely as a crypto asset, and at what horizon is it trading as a leveraged macro asset? Because the answer is no longer one or the other. It is both, depending on where you look.
