Bitcoin's (CRYPTO: BTC) long-standing pitch as "digital gold" is facing a macro reality check. On Federal Reserve announcement days, the ETFs tracking it are behaving like high-growth tech proxies, moving in sync with interest rate expectations and liquidity signals.
Heading into the latest Fed policy decision and Jerome Powell's press conference, trading patterns across major spot Bitcoin ETFs show a clear shift. Funds such as the iShares Bitcoin Trust (NASDAQ:IBIT), Fidelity Wise Origin Bitcoin Fund (BATS:FBTC), ARK 21Shares Bitcoin ETF (BATS:ARKB), and Grayscale Bitcoin Trust ETF (NYSE:GBTC) are increasingly moving more or less alongside equity benchmarks rather than acting as diversifiers.
On Wednesday morning, all the funds were trading marginally lower at less than 1%, same as the S&P 500. Meanwhile, the Nasdaq 100 index was not very far ahead, and was trading less than 1% higher.
From ‘Digital Gold’ To Macro Trade
The data tells the story. Bitcoin's correlation with major equity indices has climbed sharply in recent years, with some estimates placing its relationship with U.S. stocks as high as 0.7–0.8 during macro-driven volatility. For instance, AhaSignals placed Bitcoin-Nasdaq correlation for a 30-day reading at 0.72 as of Feb 27. Meanwhile, AInvest said that the 30-day coefficient between Bitcoin and the S&P 500 climbed to 0.74 earlier this year.
That puts it closer to risk assets like the Nasdaq 100 and other tech stocks than to traditional hedges.
This shift is rooted in liquidity. When the Fed signals easier financial conditions, capital flows into higher-beta assets, lifting both tech stocks and crypto ETFs. Conversely, hawkish surprises tend to drain liquidity, triggering synchronized sell-offs.
Flow trends reinforce the pattern. Data from SoSoValue shows that U.S.-listed spot Bitcoin ETFs have seen strong inflows ahead of key Fed meetings, often followed by sharp outflows when policy commentary turns restrictive. The behavior closely mirrors movements in growth-heavy funds like the Invesco QQQ Trust (NASDAQ:QQQ).
ETF Structure Is Amplifying the Shift
The rise of spot Bitcoin ETFs has fundamentally changed how investors access crypto. By packaging Bitcoin in a familiar format, ETFs have brought in institutional allocators and macro-driven traders who manage exposure across asset classes—not in isolation.
That means Bitcoin is increasingly being traded as part of a broader portfolio strategy, adjusted alongside equities and bonds based on rate expectations and risk sentiment. In effect, crypto ETFs have been absorbed into the same playbook that governs traditional markets.
As macro conditions grab the limelight, Bitcoin funds are increasingly behaving like high-beta extensions of the broader market, reacting less to crypto-specific narratives and more to the direction of monetary policy.
