US Core Inflation Surges, Raising Odds for Federal Reserve Rate Hike

The Federal Reserve is facing renewed pressure as the August Consumer Price Index (CPI) report shows core inflation climbing higher than expected. The core CPI increased by 0.3% month-over-month, surpassing economists' predictions of 0.2%. This has led to a sharp rise in the likelihood of a 25-basis-point rate hike at the Federal Open Market Committee (FOMC) meeting on September 16, with the probability now sitting at 90%, up from approximately 70% just a day earlier.

The Bureau of Labor Statistics released the CPI data on September 11, revealing that the core CPI, which excludes volatile food and energy prices, rose 2.4% year-over-year. The headline CPI also reflected significant increases, with a 0.4% rise month-over-month and a 3.4% year-over-year increase, both aligning with forecasts but remaining concerningly high.

Energy prices, particularly oil, have been a major contributor to these inflationary pressures, with oil nearing $100 per barrel. This situation is complicating the Fed's inflation-fighting efforts, as rising energy costs impact transportation, manufacturing, and supply chains.

Market expectations have shifted dramatically from earlier in the year, when many anticipated multiple rate cuts. Fed Chair Kevin Warsh, initially seen as dovish, now appears to be aligning with more hawkish voices within the Fed, emphasizing the need for price stability.

The implications for risk assets, including Bitcoin, are significant. Historically, Bitcoin and other digital assets have moved inversely with real interest rates. As yields rise, the opportunity cost of holding non-yielding assets like Bitcoin increases, potentially driving capital toward safer investments. However, some investors still view Bitcoin as a long-term hedge against inflation.

As the September 16 meeting approaches, traders are grappling with the implications of these inflation figures and the likelihood of further rate hikes later in the year. The Fed's decision will depend on a range of factors, including employment data and the persistence of recent price increases.

New Facts on US Core Inflation

Federal Reserve Chairman Kevin Warsh faces increasing pressure to address interest rates following the August 2026 Consumer Price Index (CPI) report.

The report showed a 0.4% month-over-month increase in headline CPI and a 3.4% year-over-year rise, exceeding the Fed’s 2% inflation target.

Core CPI, which excludes food and energy prices, rose by 0.3% monthly and 2.4% annually.

The data, particularly influenced by rising gasoline prices, has intensified discussions on potential rate hikes by the Fed.

Current market pricing indicates a strong likelihood of interest rate hikes, with reduced chances of rate cuts in upcoming Federal Reserve meetings.

Market participants are closely watching for any indications of policy shifts from Fed Chairman Warsh, especially regarding persistent inflation.

Upcoming Federal Open Market Committee (FOMC) meetings and new economic data will be critical in shaping the Fed's decision-making process.

Recent Developments in Federal Reserve Operations

The Federal Reserve's overnight reverse repurchase agreement facility recently accepted $4.736 billion from four counterparties. This amount is significantly lower compared to the peak of over $2.5 trillion in late 2022, marking one of the most dramatic liquidity shifts in recent history.

The current offering rate for the reverse repo facility is 3.50%, and each eligible counterparty can park up to $160 billion individually. The decline in balances reflects the Fed's success in draining excess liquidity accumulated during its pandemic-era bond-buying program.

As of 2026, daily operations frequently fall below $1 billion, indicating that the financial system is functioning normally without the surplus liquidity seen post-pandemic. This situation suggests that the Fed has less cushion for liquidity tightening, which could impact future monetary policy decisions.
