This capital surge reversed previous withdrawal trends and elevated aggregate assets to approximately $140 billion.
Bitcoin Products Dominate Capital Inflows
Bitcoin-centered investment products captured $793 million in net additions during the most recent week, which accounted for roughly three-quarters of overall contributions. Throughout a three-week window, Bitcoin-related vehicles drew in $2.2 billion, maintaining a streak that accumulated $2.8 billion collectively. Nevertheless, March 18 data revealed approximately $130 million in withdrawals, primarily driven by Fidelity’s FBTC experiencing $103 million in redemptions and Grayscale’s GBTC recording $18.8 million in exits.

BlackRock’s IBIT dominated the contribution rankings by securing more than $600 million throughout the week. This flagship product represented approximately 78% of aggregate Bitcoin ETF inflows and expanded its cryptocurrency holdings beyond 784,000 BTC. Concurrently, Strategy maintained approximately 761,000 BTC, reducing the differential between these two major institutional holders.
Bitcoin’s valuation declined more than 4% across a 24-hour window, retreating from levels above $74,000 to approximately $71,000. The aggregate cryptocurrency market valuation contracted nearly 4% following the Federal Open Market Committee session and settled at $2.44 trillion. Trading volumes throughout this timeframe reached approximately $110.5 billion.
Exchange wallet balances diminished to roughly 2.44 million BTC, establishing multi-year minimum levels. Stablecoin circulation expanded to an unprecedented $306 billion amid the ongoing inflow momentum. Bitcoin rallied almost 20% from February’s bottom near $60,000 prior to the most recent correction.
Mixed Performance Across Crypto Investment Vehicles
Ethereum-focused investment products accumulated $315 million throughout the preceding three weeks, though year-to-date performance remained essentially neutral. March 18 witnessed Ethereum funds experiencing more than $55 million in redemptions. Fidelity’s FETH registered $37.11 million in outflows, while Grayscale’s ETHE documented $8.8 million in withdrawals.
Ether’s price retreated 6% during the previous 24-hour period and exchanged hands near $2,198 at publication. Aggregate cryptocurrency fund contributions achieved $1.06 billion during the latest week, establishing the most substantial weekly intake since mid-January. The Kobeissi Letter noted, “This marks the third consecutive weekly intake, bringing the total to +$2.8 billion.”
The United States represented approximately 96% of the previous week’s contributions, whereas Canada, Switzerland, and Hong Kong delivered more modest additions. Germany documented its initial weekly decrease of the current year during this identical timeframe. From the commencement of regional tensions, aggregate crypto ETF assets appreciated 9.4% to reach approximately $140 billion.
The Federal Reserve maintained current interest rate levels and communicated that reductions remain distant. Chair Jerome Powell emphasized that escalating petroleum prices continue influencing inflation projections. Monetary authorities elevated their 2026 inflation estimate to 2.7% from 2.4%, based on official economic forecasts.
