Spot bitcoin ETFs booked $517.19 million in net inflows on Wednesday, the largest single-day haul since May 4 and a sharp reversal from the choppy flows that defined July and August. BlackRock's IBIT led the field at $284.7 million, with Ark & 21Shares' ARKB adding $77.7 million and Fidelity's FBTC logging $62.4 million; eight of twelve spot funds printed positive on the day.
Why it matters
The print is a function of two macro shifts stacking at once. The U.S. Treasury announced it will at least double the size of liquidity-support buyback operations across the 10- to 30-year nominal coupon segment, which Jeff Mei, COO of BTSE, told The Block signals a softer dollar and a return of risk appetite. The SEC followed with a proposed rule creating tailored exemptions for certain crypto investment contracts, allowing issuers to raise up to $5 million over four years or $75 million annually subject to disclosure requirements. Rachael Lucas of BTC Markets framed the flow as institutional positioning rather than retail FOMO: "these are typically longer-horizon allocations from players who have the compliance frameworks and balance-sheet capacity to move size."
Market impact
Bitcoin reclaimed $69,000 for the first time in two months, up 8.3% over 24 hours to $69,564, and ether cleared $2,000 on an 18% surge to $2,251. XRP and Solana both added roughly 10%. Hyperliquid's HYPE led altcoin gainers after President Trump said CFTC Chair Michael Selig is working to bring the perpetuals-focused venue into the U.S. in a "fully compliant and legal fashion," and Lighter's LIT added 23.5% to $2.84. Both Lucas and Mei cautioned that the magnitude is unlikely to repeat without confirmation that Treasury buybacks are an ongoing initiative rather than a one-off; next week's CPI print and any Bessent commentary are the next catalysts to watch.
