Bitcoin Surges Ahead of S&P 500: The Rise of Crypto ETFs in a Volatile Month

The past month has been a pivotal period for cryptocurrency markets, with Bitcoin outperforming the S&P 500 by a significant margin amid geopolitical tension and shifting investor sentiment. . While the S&P 500 declined 11.6% in the immediate aftermath of U.S. tariff announcements on April 2, Bitcoin rebounded sharply after a 90-day tariff suspension on April 9, culminating in a 48.1% outperformance over equities. This divergence underscores Bitcoin’s growing role as a macro-hedging tool—and the critical role of Bitcoin ETFs in institutionalizing its adoption.

Bitcoin’s Volatile Month: A Hedge Against Uncertainty

Bitcoin’s journey this month was marked by extreme volatility. After falling to $75,000 by April 2—down 10.5% from its January high—it surged 8.2% on April 9 following the tariff suspension. By April 22, it stabilized near $84,500, with technical indicators signaling further upside potential. .

The catalyst? U.S. President Donald Trump’s “Liberation Day” tariffs, which targeted Chinese tech exports, triggered a flight to perceived safe havens. While gold (via GLD) rose 22% since January, Bitcoin’s correlation with equities dropped sharply. The BTC vs. S&P 500 divergence coefficient fell from 0.16% to 0.083%, signaling a shift toward Bitcoin as a standalone asset class. This is a stark contrast to its 2022 performance, when Bitcoin fell 65% alongside a 19% decline in the S&P 500.

The ETF Lens: Democratizing Bitcoin Exposure

The surge in Bitcoin’s price would not have been possible without the growth of regulated Bitcoin ETFs, which have become the primary vehicle for institutional and retail investors alike.

Top Bitcoin ETFs: Performance and Market Share

1. iShares Bitcoin Trust ETF (IBIT): With $48.12 billion in assets under management (AUM) as of April 19, IBIT dominates the space. Its 0.12% expense ratio (waived until 2025) and high liquidity make it a favorite for index investors. .
2. Fidelity Wise Origin Bitcoin Fund (FBTC): At $16.34 billion AUM, FBTC appeals to institutions seeking a grantor trust structure.
3. Grayscale Bitcoin Mini Trust (BTC): With a 0.15% fee, it targets cost-sensitive investors, amassing $3.6 billion AUM.

In contrast, legacy funds like Grayscale’s original GBTC (1.5% fee) have seen outflows, underscoring the premium investors place on low-cost access.

Why ETFs Matter: Liquidity, Regulation, and Institutional Trust

Bitcoin ETFs have three key advantages:
1. Regulatory Safety: Unlike decentralized exchanges, Bitcoin ETFs operate under SEC oversight, reducing counterparty risk.
2. Liquidity: IBIT, for instance, averages 46 million shares traded daily—a stark contrast to the fragmented OTC markets of 2020.
3. Policy Tailwinds: Trump’s pro-crypto stance and the EU’s MiCA regulation have reduced volatility. Bitcoin’s annualized volatility dropped to 52% in March 2025, down from 95% in 2021.

This institutional credibility is reflected in Bitcoin’s price action: its correlation with Nasdaq stocks fell to 0.16% in April, compared to 0.65% during the 2022 crash.

The S&P 500’s Struggles: A Mirror of Macro Uncertainty

While Bitcoin thrived, the S&P 500 mirrored its early volatility. The index fell 11.6% immediately after the tariff announcement but rebounded 9.5% on April 9—a reflection of its sensitivity to trade policy. However, the broader trend remains bearish: the S&P 500 is still down 19% since 2022’s peak, far outperforming Bitcoin’s recovery.

The divergence highlights a key theme: investors now view Bitcoin as a distinct asset class, decoupled from traditional equity markets. This is particularly evident in sectors like tech, where stocks like Nvidia—hit by $5.5 billion in tariff-related charges—underperformed.

New S&P 500 ETFs: Diversification or Distraction?

Even as Bitcoin ETFs dominate headlines, new S&P 500-linked products aim to address concentration risks. For example, the iShares S&P 500 3% Capped ETF (TOPC) limits any single stock to 3% of holdings, reducing exposure to megacaps like Apple. Similarly, the Global X S&P 500 U.S. Revenue Leaders ETF (EGLE) targets firms with >50% domestic revenue—a play on trade policy resilience.

However, these ETFs face an uphill battle. Existing S&P 500 ETFs like VOO (0.03% fee) and SPY (0.09% fee) remain benchmarks for passive investors. The new funds’ expense ratios and track records remain untested, though their strategies align with a broader market shift toward risk mitigation.

Conclusion: Bitcoin’s Institutionalization Is Here to Stay

Bitcoin’s outperformance over the S&P 500 in April 2025 is more than a short-term blip—it’s a sign of its evolution into a macro-hedging tool. With Bitcoin ETFs now holding over $53 billion in AUM and volatility dropping to 52%, the asset class is attracting institutional capital at scale.

The data is clear:
- Bitcoin’s divergence from equities hit a 48.1% premium in April.
- Low-cost ETFs like IBIT and BTC are capturing 90% of inflows.
- Regulatory clarity and policy support are reducing Bitcoin’s volatility to levels comparable to gold.

For investors, the message is straightforward: Bitcoin’s rise is no longer just for speculators. As ETFs democratize access and macro risks persist, it’s a critical component of a diversified portfolio.
