Bitcoin spot ETFs recorded $1.2 billion in net inflows for the week ending May 21. BlackRock's IBIT led with $680 million. Fidelity's FBTC added $310 million. This marks the fourth consecutive week of positive flows.
The Institutional Thesis Pension funds and endowments continue allocating to Bitcoin as a core treasury asset. The weekly inflows demonstrate a structural bid from large institutions rather than retail speculation. These flows have persisted despite price volatility in recent months. Additional capital from family offices and corporate treasuries has also entered through these vehicles. The allocation trend reflects growing recognition of Bitcoin's role in portfolio construction. Institutions cite its low correlation to traditional assets and potential as an inflation hedge. This shift in capital allocation marks a departure from previous cycles driven primarily by retail participation.
BlackRock's IBIT alone captured $680 million of the total. Fidelity's FBTC contributed $310 million. Combined, these two funds accounted for over 80 percent of the weekly inflows. Other spot products saw smaller but still positive contributions.
What the Onchain Data Shows Long-term holders added 42,000 BTC to their positions over the past week. Exchange reserves declined to 2.4 million BTC. This represents the lowest level since 2023 and signals continued withdrawal of supply from liquid markets. The supply contraction occurs alongside steady demand from new addresses. Network activity remains robust with consistent daily active addresses across the blockchain.
The MVRV ratio currently stands at 1.85. This metric sits comfortably below the 2.4 threshold observed at prior cycle peaks. Long-term holders maintain a realized price of $62,400. Price action near current levels reflects accumulation behavior rather than profit-taking. This combination of rising long-term holdings and moderate valuation metrics points to a healthy market structure.
Bearish risks remain real. A sharp rise in the dollar index or surprise regulatory developments could trigger rapid outflow reversals. Short-term holders continue to control approximately 28 percent of circulating supply and exhibit higher sensitivity to price fluctuations.
U.S. M2 money supply expanded 5.8 percent year-over-year. Treasury issuance remains elevated as fiscal deficits persist. Bitcoin's hard cap of 21 million coins provides a fixed supply contrast to ongoing monetary expansion. This dynamic supports the case for Bitcoin as a hedge in an environment of continued fiat debasement. Central banks globally have expanded balance sheets in parallel fashion over the past decade. The resulting liquidity environment favors assets with verifiable scarcity.
