‘Only hedge funds, retail sold’ — Will BTC Sustain Rally as Bitcoin ETF Flows Turn Positive?

Five-Day Inflow Surge Turns YTD Flows Positive

U.S. Spot Bitcoin exchange-traded funds extended a winning streak to five consecutive sessions, amassing $2.65 billion in net inflows and marking a decisive shift in market sentiment. According to Galaxy Research data, the complex attracted $1 billion on Monday alone, followed by $714 million on Tuesday and $346 million on Wednesday. The sustained demand lifted year-to-date flows into positive territory for the first time, registering a net $349 million inflow since January. The bullish wave propelled Bitcoin to an eight-month peak of $87,000, signaling renewed institutional conviction after months of sideways price action.

BlackRock Leads Institutional Demand Amid Cumulative Flow Recovery

BlackRock’s IBIT fund drove approximately half of the five-day inflow total, underscoring the asset manager’s dominant position in the Bitcoin ETF landscape. The recent surge has significantly repaired cumulative flow metrics that had deteriorated sharply since October 2023. Galaxy Research figures show cumulative flows had contracted by $12 billion, equivalent to 77,800 BTC, during the preceding drawdown. The current rebound has erased roughly half that deficit, with cumulative flows now down only 5.7% from inception highs, standing at approximately $55 billion in total assets despite the crypto winter.

Bloomberg analyst James Seyffart noted that the recent traction could soon help the cumulative flows (aggregate demand since inception) turn positive too. Seyffart added that the outflows were mainly driven by hedge funds and retail. “By far, the biggest sellers of the ETFs over the last ~year were hedge funds and retail traders/investors.” This distinction highlights a structural shift: while speculative participants exited positions during the downturn, institutional allocators have maintained or expanded exposure, providing a more resilient demand base.

Macro Headwinds: Bond Yields and Fed Rate Hike Fears

Despite the ETF momentum, Bitcoin’s advance stalled mid-week as macroeconomic pressures intensified. The 10-year U.S. Treasury yield climbed to 5.1%, while oil prices ticked higher, reigniting inflation concerns across risk markets. Interest rate traders, per CME FedWatch data, priced a 64% probability of another Federal Reserve rate hike at the October meeting. This repricing dampened risk appetite and dragged Bitcoin from its $87,000 high to below $84,000, a decline of approximately 4% in short order.

Historical precedent offers a nuanced perspective. In the past, U.S. Treasury intervention plans to control bond yields have been viewed as net inflationary and an overall boost to scarce assets such as BTC and gold. Whether that narrative will hold and drive BTC higher remains to be seen. For the rate hike fears, however, the asset typically remains muted before the Fed decision and tends to push higher afterwards. Market participants are closely monitoring whether the current ETF demand can withstand sustained bond market volatility.

Technical Analysis: $82K Weekly Close as Key Confirmation Level

From a technical standpoint, analyst Benjamin Cowen projected that the uptrend could only be confirmed if there is a weekly candlestick close above $82K (May peak). This level, corresponding to Bitcoin’s previous local high from May, serves as a critical structural reference point. A weekly close above this threshold would validate the breakout structure and suggest the recent ETF-driven rally has legs beyond short-term momentum. Conversely, failure to reclaim and hold $82,000 on a weekly basis could expose the asset to further consolidation or retest of lower support levels.

Why This Matters

The five-day inflow streak represents the most sustained institutional accumulation since the ETFs’ January launch, suggesting that the “crypto winter” narrative has fundamentally shifted for professional allocators. BlackRock’s outsized participation signals deepening integration of Bitcoin into traditional portfolio construction. However, the immediate price reversal underscores that Bitcoin remains acutely sensitive to Federal Reserve policy expectations and Treasury market dynamics. The interplay between ETF flow momentum—now structurally positive on a cumulative basis—and macro liquidity conditions will likely dictate Bitcoin’s trajectory through the fourth quarter. Investors should watch the October Fed meeting, weekly close above $82,000, and whether cumulative flows breach inception highs as key catalysts.
