Bitcoin (BTC) Slips Below $79,000 Ahead of Make-or-Break August CPI Release

CPI Verdict Looms Over Bitcoin

Bitcoin (BTC) slid below the $79,000 level on September 11 as traders trimmed exposure in the hours before the August US consumer price index (CPI) release, the final major inflation print before the Federal Reserve's September 16 meeting. Our read of positioning ahead of the data: market desks are treating a core CPI month-on-month figure of 0.3% as the dividing line for the outcome. At or above that threshold, implied odds of a quarter-point hike at the September gathering would be pushed toward 90%. A 0.2% print, in line with consensus, would leave the hike debate fully open and hand the decision to the committee itself. Only a reading of 0.1% or lower would pull odds back toward a coin flip, with most desks then expecting the Fed to stand pat — a reprieve, not an all-clear.

Wharton economist Jeremy Siegel told CNBC's Closing Bell that Chair Kevin Warsh will choose to hike, arguing that skipping would invite four, five or even six dissent votes, an outcome he described as unprecedented. July's FOMC meeting already produced three dissents, with Beth Hammack, Neel Kashkari and Lorie Logan all voting to raise rates — the most early-tenure opposition for a new chair since the 1970s. Notably, Warsh has not smoothed over those splits, letting the committee's disagreement surface publicly. Siegel's sequencing for a hike: an initial wave of selling, then a rally in long-dated Treasuries as investors conclude the Fed is serious about inflation, and only after the bond market stabilizes would equities be pushed back up. For stocks and crypto alike, that order means absorbing the shock first and waiting for bonds to supply the answer. Whatever the print, the tradable outcome for Bitcoin (BTC) traders now runs through the Treasury curve, not through crypto-specific catalysts.

Oil at $110, Yields at Multi-Year Highs

The pressure on risk assets did not appear in a vacuum. Fighting has spread from Iran to Yemen and Saudi Arabia, with mutual air strikes and Houthi advances along the Red Sea casting a longer shadow over the Hormuz and Bab el-Mandeb chokepoints. Brent crude jumped 6.3% on September 10 to $107.63 per barrel and touched $110 in early trading. The bond market repriced violently alongside it: the 10-year Treasury yield spiked 11 basis points intraday to 4.954%, its highest since October 2023, while the 2-year rose 13 basis points to 4.56% and the 30-year pushed up to 5.368%. A Treasury buyback of roughly $5.2 billion in 10- and 20-year paper came in below the anticipated $6 billion and did little to calm the tape. The selloff was global — the UK 10-year broke above 5.37%, a level last seen in 2007; Germany's 10-year reached 3.5%, a 15-year high; and Japan's 10-year cleared 3% for the first time in three decades, a move we previously flagged as a yen-carry unwind risk for Bitcoin (BTC). The European Council's counterpart, the ECB, hiked 25 basis points to 2.65%, its second increase since the Iran conflict began.

Domestic inflation data added fuel: August PPI rose 5.4% year over year against a 5.1% forecast and July's 4.7%, with core PPI at 4.6%. That lifted the implied probability of a September 16 quarter-point hike to 67-70%, while contracts on Kalshi prediction markets and Polymarket jumped 9 percentage points in a day to 63%. Risk assets buckled in sympathy: the S&P 500 fell 0.6% to 7,594, a fourth straight decline; the dollar index gained 0.3% to 99.1; and gold slid 1.7% to $4,326 after trading near $4,700 a week earlier. Bitcoin fell 0.9% to roughly $77,140 and probed $76,651 immediately after the PPI release, and the asset remains pinned below $79,000 heading into the CPI window. Liquidation data shows about $562 million in positions wiped out market-wide over 24 hours, with whale-sized longs among the flushed. Even so, BTC's daily loss was smaller than gold's — a relative-strength divergence that will test HODL conviction if the CPI print runs hot and our Bitcoin coverage universe reprices further.

September 16 Decision in Focus

COINOTAG's aggregate market data frames the stakes: the Fear & Greed Index sits at 56/100 (Greed), Bitcoin holds 68.3% of our tracked market, and tracked market capitalization stands near $2.27 trillion — positioning that has not fully de-risked despite the macro squeeze. Tonight's CPI decides whether the September 16 hike moves from bet to consensus, and the altcoin market will take its cue from whether BTC defends the mid-$77,000s. Cycle watchers using the Bitcoin Rainbow Chart should read this as a liquidity event, not a cycle verdict.
