Bitcoin ETF Inflows Explode as Treasury Buybacks Hit Yields — Is an $80K Breakout Igniting the Next Crypto Rally?

U.S. spot Bitcoin ETFs are enjoying their strongest comeback of 2026, after several months of sluggish demand. Over an eight-day stretch, funds have seen about $2.8 billion — approximately $232 million on August 26 — in inflows, beating August’s total above $3 billion. Demand surged when Bitcoin price broke the $80,000 mark.

The move also coincided with a change in the macro environment in the United States, with market strategist Jonathan Rose attributing Bitcoin’s rebound to Treasury buybacks and declines in long-term interest rates and the dollar. August’s attempts to repair the annual ETF picture: spot Bitcoin products remain in a net outflow position for 2026.

More importantly, ETF buying already picked up, taking in $297.5 million on August 17 and $189.3 million the next day. The Treasury’s instructions to boost long-end liquidity-support buybacks were not issued until August 19, meaning demand was already returning.

Payments then soared to approximately $517.2 million on August 19 and $606.3 million the next day, as Bitcoin broke out of resistance that had been present for months.

The Treasury will double the maximum size of the liquidity-support buybacks for long-dated nominal securities from $2 billion to $4 billion per operation for the 10-to-20-year and 20-to-30-year sectors from 9 September through 4 November.
