The momentum behind spot Bitcoin exchange-traded funds (ETFs) hit a sudden pause on Thursday, December 19, as the market witnessed a dramatic reversal: a record-breaking single-day outflow of $671.9 million**. This marked the end of a 15-day streak of consecutive inflows—the longest such run since the ETFs launched in January 2024. The shift in sentiment wasn't isolated to Bitcoin; Ethereum ETFs also saw outflows, breaking an 18-day winning streak with **$60.5 million exiting the market.
This sudden reversal underscores growing uncertainty among institutional investors, triggered by evolving macroeconomic signals and regulatory clarity—or the lack thereof.
Market Reaction to Fed Chair Powell’s Comments
The sell-off followed Federal Reserve Chair Jerome Powell’s remarks during a press conference on Wednesday, which sent ripples across financial markets. Powell reiterated that the Federal Reserve is not authorized to hold Bitcoin or any cryptocurrency, emphasizing that the central bank’s role is limited to regulation and oversight—not asset acquisition.
“It seems that the US BTC ETFs are all capitulating after the news that the FED isn’t allowed to hold BTC. So does that mean no strategic Bitcoin reserve fund? Total outflows net -$671.9 million,”
— Mark Cullen, crypto analyst
While not a surprise from a legal standpoint, the confirmation dashed hopes of a future U.S. strategic Bitcoin reserve, a concept that had gained traction among pro-crypto policymakers and investors. Additionally, Powell signaled a more hawkish stance on monetary policy, tempering expectations for interest rate cuts in 2025. With inflation still above target, the Fed now anticipates only two rate cuts in 2025, down from earlier projections of three or four.

Record Outflows Across Major Bitcoin ETF Providers
According to data from Farside Investors, Thursday’s outflows were the largest since the debut of spot Bitcoin ETFs in January. The $671.9 million exodus surpassed the previous record of $564 million set on May 1, 2024.
The selling pressure was broad-based but concentrated among key players:
- Fidelity’s FBTC: Led the outflow with $208.5 million, marking its largest single-day withdrawal since inception.
- Grayscale’s GBTC: Saw $188.6 million exit, its worst performance since transitioning to an ETF.
- Ark Invest’s ARKB: Contributed over $108 million in outflows.
In contrast, BlackRock’s IBIT, Franklin Templeton’s EZBC, and Valkyrie’s BRRR remained neutral, reporting neither significant inflows nor outflows—suggesting selective investor behavior rather than a blanket market rejection.
Ethereum ETFs Mirror Bitcoin’s Downturn
The bearish sentiment extended to Ethereum ETFs, which had enjoyed an 18-day streak of positive net flows. On December 19, the market saw $60.5 million in net outflows across ETH-based funds.
Though Ethereum’s ecosystem continues to show strength—with growth in decentralized applications (dApps), Layer-2 adoption, and staking activity—investor appetite appears sensitive to broader macro conditions. Without a clear dovish pivot from the Fed, capital remains cautious.

Why This Outflow Matters
While a single day of outflows doesn’t negate the long-term bullish case for Bitcoin ETFs—especially given over $13 billion in net inflows year-to-date—it serves as a stress test for market resilience.
Several implications arise:
- Institutional Sensitivity to Policy: The speed and scale of the outflow suggest that institutional capital is highly responsive to regulatory and central bank signals.
- No "Fed Backstop" Narrative: The idea that the Fed might one day buy Bitcoin as a reserve asset has been effectively ruled out—removing a speculative tailwind.
- Rate Cut Expectations Drive Flows: With fewer rate cuts expected in 2025, risk assets like crypto may face continued pressure as yields remain attractive in traditional markets.
FAQ: Understanding Bitcoin ETF Outflows
Q: What caused the sudden Bitcoin ETF outflows on December 19?
A: The outflows followed Federal Reserve Chair Jerome Powell’s statement that the Fed cannot hold Bitcoin and his indication of fewer interest rate cuts in 2025, leading to risk-off behavior among institutional investors.
Q: Are Bitcoin ETFs still a viable investment?
A: Yes. Despite this outflow, spot Bitcoin ETFs have seen strong net inflows overall in 2024. They remain a regulated, accessible way for institutional and retail investors to gain exposure to Bitcoin.
Q: Did all Bitcoin ETFs experience outflows?
A: No. While Fidelity, Grayscale, and Ark Invest saw significant withdrawals, BlackRock’s IBIT, Franklin Templeton’s EZBC, and Valkyrie’s BRRR reported neutral flows, indicating varied investor strategies.
Q: How do Ethereum ETFs compare?
A: Ethereum ETFs also saw outflows—$60.5 million—ending an 18-day streak of inflows. However, no spot Ethereum ETF is yet approved in the U.S., so these figures reflect futures-based or international products.
Q: Could the Fed ever hold Bitcoin in the future?
A: Currently, the Fed lacks legal authority to hold cryptocurrencies. Any change would require congressional action, making it unlikely in the near term.
Q: What should investors watch next?
A: Upcoming inflation data, Fed meetings, and potential approvals for spot Ethereum ETFs will be key drivers of sentiment in early 2025.

Looking Ahead: What’s Next for Crypto ETFs?
As we approach the end of 2025, the path for crypto ETFs will depend heavily on three factors:
- Monetary Policy Direction: If inflation cools faster than expected, the Fed may resume rate cuts, potentially reigniting risk appetite.
- Regulatory Clarity: Clearer rules around digital assets could boost institutional confidence.
- Product Innovation: Expansion into ETFs for Ethereum, Solana, or even tokenized real-world assets may attract new capital.
For now, Thursday’s record outflow serves as a reminder: while crypto markets are maturing, they remain deeply intertwined with traditional finance. Investor behavior reflects not just crypto-specific developments, but global macroeconomic currents.
The end of a 15-day inflow streak doesn’t spell doom—it signals a market that’s reacting rationally to new information. And in a space often driven by hype, that’s a sign of growing sophistication.
