U.S. spot Bitcoin ETFs bled $465 million over two days last week, snapping a seven-day inflow streak that had brought in roughly $1 billion. BlackRock's IBIT accounted for nearly 90 percent of the selling, a signal that the institutions using the fund as a liquidity sleeve are trimming exposure rather than adding to it.

The numbers behind the reversal

Friday's $240 million outflow followed Thursday's $225 million, erasing almost half the prior week's gains. The streak had peaked at $227 million on July 20 before demand evaporated. Even with the two-day rout, the funds finished the week net positive by about $34 million, thanks to three strong inflow sessions earlier in the run. IBIT alone saw just under $415 million exit in 48 hours.

Macro fear, not crypto fatigue

HashKey's Tim Sun reads the reversal as institutions making "tactical, phased allocations near the temporary price bottom", code for a lack of conviction. He ties the move to a broader risk-off wave: U.S.-Iran tensions pushed oil above $100, bond markets priced higher odds of a Fed rate hike, and U.S. stock and bond funds both posted outflows. Bitcoin, in this reading, is just another risk asset getting sold when correlations converge.

The bull case hasn't left the building

Grayscale's Zach Pandl argues the bottom "may already be in" if the Fed holds rates steady, dismissing the four-year cycle theory that points to a deeper low in the fall. Algoz's Stephen Wundke agrees most investors see current prices near the cycle bottom and remain optimistic. A pause in Red Sea hostilities could send oil back toward $80, easing inflation fears and reopening the inflow tap. August is historically dull for crypto, so the real test comes later.

What to watch

The Fed's July 29 decision, previewed as a 34 percent chance of a 25-basis-point hike by CME FedWatch, was the near-term test Pandl identified. Bitcoin sits at $65,300, up 1.9 percent on the week. Prediction markets now give a 37 percent probability of an $84,000 move, up from 20 percent at the start of July. If the central bank paused, the ETF flow picture could flip as quickly as it did last week, institutions have shown they can move in and out of IBIT at speed.
