Bitcoin at $77,300 as CPI repricing raises September rate-hike odds to 83%
The supply wall in $BTC, built by long-term holders distributing 539,000 Bitcoin into the $77,000-to-$80,000 zone this year according to CryptoQuant, has capped every rally attempt toward $80,000. When August CPI came…
Key takeaways
- Bitcoin traded near $77,300-$77,400 on September 12, down from $79,155 on September 9 and a September 4 intraday peak of $82,000.
- A hot August CPI reading on September 11 pushed Polymarket's probability of a September 16 Federal Reserve rate hike to 83%.
- Long-term holders have distributed 539,000 Bitcoin into the $77,000-to-$80,000 zone this year, creating a supply wall that has capped rallies toward $80,000, according to CryptoQuant.
- US spot Bitcoin ETFs lost $13.29 million on September 11, a fourth consecutive outflow session, after pulling in $986.9 million the prior week ending September 4.
- The $76,500-to-$77,000 band is the key level, and a close below $76,500 opens a move toward $72,000-$74,000, roughly 7.0% below current levels.
The supply wall in $BTC, built by long-term holders distributing 539,000 Bitcoin into the $77,000-to-$80,000 zone this year according to CryptoQuant, has capped every rally attempt toward $80,000. When August CPI came in hot on September 11 and moved Polymarket's probability of a September 16 Federal Reserve rate hike to 83%, that supply pressure compounded. Bitcoin traded near $77,300 on September 12, with the FOMC decision three sessions away.
The macro repricing
Core CPI rose 0.3% month over month in August against a consensus estimate of 0.2%. The Federal Reserve's target rate upper bound sits at 3.75%, unchanged since December 2025, and the rates market repriced sharply on the same day. The VIX closed at 17.84 on September 10, up 24.6% in a week, as equity markets ran the same repricing.
The oil component fed directly into the CPI result. Brent crude broke $100 a barrel on September 9, hours after US forces struck Iran-linked tankers near the Strait of Hormuz. Energy prices pass through to transportation, packaging, and manufacturing costs, so crude holding above $100 worked its way into the August reading.
Bitcoin traded near $77,400, down from $79,155 on September 9 and from an intraday peak of $82,000 on September 4, declines of 2.2% and 5.6% respectively. The coin carries no coupon and no cash flow, so when a government bond pays close to 5%, the cost of holding Bitcoin relative to yield-bearing alternatives rises.
ETF flows and the level to watch
US spot Bitcoin ETFs lost $13.29 million on September 11, the fourth consecutive outflow session. The prior week, ending September 4, had pulled in $986.9 million. When ETFs redeem shares, authorized participants sell spot Bitcoin to fund the redemption, so four days of outflows translates into direct selling pressure after a summer of passive buying.
The setup from here hinges on the $76,500-to-$77,000 band, which held on the CPI-day selloff and aligns with the lower edge of the 539,000-coin supply wall. A close below $76,500 opens a move toward $72,000-$74,000, roughly 7.0% below current levels. Bitcoin implied volatility was near 40 heading into the decision, wider than options markets priced through most of the summer. A softer FOMC outcome could ease yield pressure and potentially flip ETF flows positive; hawkish guidance would push Bitcoin toward the lower band instead. The decision is September 16.
