Why Bitcoin initially held its gain as rate traders put September hike odds at 85%

August’s inflation report left the Federal Reserve with a mixed signal: gasoline drove much of the headline increase, but monthly core inflation accelerated. That combination kept Governor Christopher Waller’s conditional case for a rate hike in play even as Bitcoin held its daily gain.

CryptoSlate's live Bitcoin market data had BTC at $78,683, up 2.08% over 24 hours, when trading closed in the US for the week. In contrast, Reuters reported that futures had moved to about an 85% probability of a quarter-point increase at the Fed's September 15-16 meeting, from about 70% before the inflation report. CME says its FedWatch probabilities are derived from 30-Day Fed Funds futures.

The policy tension lay inside the inflation report: annual core inflation eased, while its latest monthly pace picked up.

CPI composition cut both ways

The Bureau of Labor Statistics said the consumer price index increased 0.4% in August on a seasonally adjusted basis after a 0.1% rise in July. The unadjusted 12-month rate stayed at 3.4%.

Gasoline supplied the clearest reason to look beneath the headline. Its index rose 3.9% and accounted for more than one-third of the monthly all-items increase, while the broader energy index gained 2.1%.

That composition could support a limited relief case for Bitcoin. An outsized contribution from a volatile component does not carry the same policy signal as a similarly broad increase across the basket.

The report did not, however, deliver an energy-only inflation story. Core CPI, which excludes food and energy, rose 0.3% in August after a 0.2% increase in July. Its annual rate eased to 2.4% from 2.5%, creating the central split: the longer-run measure improved while the latest monthly pace accelerated.

Other parts of the basket showed pressure too. Shelter rose 0.3% in August, and services excluding energy services were up 3.0% over 12 months. Gasoline explained a large share of the headline move, but not the entire report.

Federal Reserve Governor Christopher Waller had made August inflation central to his next decision. In a September 3 speech, Waller said continued progress toward the Fed's 2% goal would incline him to support holding the policy rate steady. He also said a hot report, or evidence that progress had reversed, could lead him to consider a hike at the September 15-16 meeting.

Waller described that view as a reaction function, not a commitment. His comments do not determine how he or the committee will vote. They do show why the monthly core acceleration cannot be dismissed simply because annual core inflation edged lower.

Waller also said core inflation was useful for seeing through energy volatility and that broader spillovers from earlier energy increases had not appeared so far. At the same time, he identified renewed energy pressure and a possible rise in longer-term inflation expectations as risks the Fed should watch.

The August report therefore landed between the two sides of his test. Annual core inflation moved closer to target, but the latest monthly core reading moved away from the pace seen in July. The futures response showed that traders gave substantial weight to the latter risk.

September’s energy risk lies beyond August CPI

Bitcoin's 24-hour move still needs careful handling. During Saturday trading, Bitcoin has fallen to around $77,500 into thin weekend liquidity.

Also, Friday's release describes August, so it cannot include the sharper oil-price move that developed in September.

CryptoSlate's pre-CPI analysis highlighted that timing gap. The new energy shock is not evidence inside August CPI, and it would be premature to say it has already spread into broader prices. It can still matter through future inflation data and expectations, the channels Waller identified as policy risks.

August CPI gave policymakers a reason to look through part of the gasoline-led jump, but faster monthly core inflation complicated the case for a hold. Whether September’s energy pressure persists or spreads remains a separate risk for subsequent data and inflation expectations.
