Bitcoin faces a new macro test as Fed Chair Kevin Warsh highlights sticky inflation metrics

Bitcoin’s price action is now being measured against a new macro indicator cited by Federal Reserve Chair Kevin Warsh: the share of the personal consumption expenditures (PCE) basket that has risen faster than 3% over the past year.

Warsh’s inflation breadth metric

Warsh said 54% of the 199 PCE components increased at an annual rate above 3% over the last 12 months, while 49% did so over the most recent six‑month period. The 12‑month breadth has fallen from a post‑pandemic peak of nearly 77% but remains well above the pre‑pandemic average of 32%.

Bitcoin’s price near $80,000

After briefly reaching $81,280, Bitcoin slipped below $80,000 during Asian trading and has hovered around $79,000. The price level is now a focal point for traders assessing whether crypto‑specific demand can offset tighter monetary conditions.

ETF inflows as a counterweight

U.S. spot Bitcoin ETFs have absorbed more than $1.1 billion across four trading sessions ending August 27. Daily net inflows were $337.6 million (Aug 24), $314.3 million (Aug 25), $232.2 million (Aug 26) and $242.3 million (Aug 27). BlackRock’s iShares Bitcoin Trust accounted for roughly 86% of the total inflows.

Treasury liquidity‑support buybacks

The Treasury announced larger buybacks in the 10‑ to 20‑year and 20‑ to 30‑year sectors, increasing the maximum per operation from $2 billion to at least $4 billion starting September 9 through November 4. These operations aim to improve trading in less‑liquid securities and reduce market‑functioning friction.

Implications for Bitcoin

The combination of ETF inflows and upcoming Treasury buybacks can cushion short‑term volatility, but they do not replace the need for disinflation. With headline PCE inflation at 4.1% (annualized six‑month rate) and the Fed’s 2% target unchanged, tighter policy remains a risk. Bitcoin, which yields no income, may face pressure from higher discount rates unless crypto‑specific demand remains strong.

Key tests for a durable rally

• Continuation of ETF inflows beyond the immediate post‑speech period.
• Broadening of inflows beyond BlackRock’s iShares Bitcoin Trust.
• Reclaiming and holding the $80,000 price level.
• Subsequent inflation data that lower the 54% and 49% breadth readings.
