August CPI Puts Fed Policy in Focus as Hike Odds Reach 90%

Markets were betting on a 90% chance of a Federal Reserve rate hike at Wednesday’s policy meeting, according to CME FedWatch, as reported by Yahoo Finance. FOMC Polymarket odds are similar, at an 82% chance of a hike.

The shift followed an August inflation report in which core CPI, excluding food and energy, rose 0.3% month over month, above expectations for a 0.2% increase. Headline CPI rose 0.4% during the month and 3.4% over the previous 12 months.

The available evidence does not establish a Bitcoin price reaction to the inflation report or a specific outcome for Bitcoin and altcoins from the Fed meeting.

For crypto market participants, the immediate takeaway is uncertainty: the policy decision and officials’ assessment of inflation remain the central events to monitor, rather than a confirmed crypto-market response.

The 90% figure is a market-implied reading reported through CME FedWatch, not a Federal Reserve announcement or a guaranteed policy outcome. It shows that traders were assigning a high likelihood to a hike at Wednesday’s meeting after the August CPI release.

That distinction is important. Market expectations can change, while the Fed’s decision had not yet been announced. Yahoo Finance reported that officials would use the latest inflation figures to assess whether price pressures were easing over the past three, six, and 12 months.

Officials remained divided over whether inflation was returning to the Fed’s 2% goal on its own or whether it would need additional rate increases.

What the Inflation Data Says

The Bureau of Labor Statistics reported a 0.4% increase in the all-items CPI for August, following a 0.1% gain in July, with a 3.4% rise over the past year. The index excluding food and energy rose 0.3% in August, easing its annual rate to 2.4%.

Energy drove the monthly figures, with gasoline up 3.9% and contributing to more than a third of the overall increase. Economists viewed the stronger core reading as a reason for a potential interest rate hike, with some expecting further increases to guide inflation back to 2%.

Fed officials had mixed opinions; some were open to maintaining rates if inflation showed progress, while others believed higher rates may be needed to curb broad-based inflation.

Why Oil Matters to the Fed Debate

A rebound in oil toward $100 per barrel added another layer of complexity to the inflation discussion. Evercore ISI’s Krishna Guha said the policy question was whether better summer inflation data gave the Fed enough reassurance to look through a renewed oil supply shock affecting diesel and other refined products.

Yahoo Finance noted that the Fed’s standard approach is to look through oil-price shocks and focus on underlying inflation dynamics, and it is catalysts like this driving the FOMC Polymarket odds surging above 80% for a rate hike.

But the report also said that inflation had remained above the Fed’s 2% goal for five and a half years and that the oil shock followed other disruptions, including tariffs, the war in Ukraine, and the pandemic. Brusuelas argued that the prolonged supply shocks warranted a forward-looking policy response.
