BTC reached roughly $79,500 on Aug. 21, its highest level in about three months, after climbing more than 20% during its strongest week since March 2024. Bitcoin was holding around $77,000 on Monday, Aug. 24, after giving back part of the move.
The catalyst was a U.S. Treasury decision to at least double liquidity-support buybacks for 10- to 30-year bonds, lifting the maximum size from $2 billion to at least $4 billion per operation beginning Sept. 9. The Treasury said the change is intended to improve liquidity in longer-dated securities.
Markets reacted quickly. Long-term yields initially fell, the dollar weakened, and investors moved toward scarce assets including Bitcoin and gold.
ETF Money Turned the Bounce Into a Breakout
The Treasury announcement may have started the move, but institutional demand helped keep it alive.
U.S. spot Bitcoin ETFs took in $517.2 million on Aug. 19 and another $606.3 million on Aug. 20, according to Farside. Weekly Bitcoin ETF inflows reached roughly $1.9 billion, while combined Bitcoin and Ethereum products attracted about $2.6 billion.
That was a sharp reversal from the weak flows seen earlier in August. Coinpaper’s recent ETF flows coverage showed institutional demand returning just as BTC cleared $69,000. Investors unfamiliar with the structure can also see how a spot Bitcoin ETF channels traditional brokerage money into Bitcoin exposure.
Short covering accelerated the move. More than $4 billion in bearish crypto positions were liquidated during the rally, forcing traders who had bet against Bitcoin to buy back into a rising market.
$80K Becomes the Immediate Test
The question now is whether Bitcoin can turn a liquidity-driven breakout into sustained demand.
BTC’s recent price outlook identified the mid-$70,000 area as an important support zone after the breakout. Holding above it would keep $80,000 within reach; losing it could invite profit-taking after a roughly 27% rebound from the Aug. 17 area.
The next major macro test comes from Fed Chair Kevin Warsh’s Jackson Hole speech and incoming U.S. inflation data.
For now, however, the strongest explanation for Bitcoin’s move is unusually clear: a Treasury bond-market intervention loosened financial conditions just as institutional ETF demand returned, and a crowded short market amplified the result.
