Core consumer prices rose 0.3% in August, exceeding market expectations and triggering a sharp repricing of Federal Reserve policy. Traders now see an 85% chance of a rate hike next week, up from 70% before the data release.

Core consumer prices increased by 0.3% in August. This figure surpassed the expected 0.2% rise. Headline inflation climbed 0.4% for the month. Gasoline prices jumped 3.9%. The data arrived after a hot producer-price report. Wall Street had grown nervous about persistent price pressure. The Federal Reserve’s next move is now in sharp focus.

Traders priced the probability of a quarter-point hike at 85%. This is up from 70% prior to the report. The 10-year Treasury yield moved toward the 5% mark. This level was previously seen as a psychological barrier. Stock indices rose despite the inflation data. The market appears to welcome the signal of tighter policy. Fed Governor Christopher Waller noted that little inflation acceleration is needed to support a hike.

Wireless Services Drive Inflation Surge

Wireless telephone services prices surged 5.9% in August. This is the largest increase recorded by the Bureau of Labor Statistics. The category contributed 0.077 points to the overall CPI rise. This amount equals one-third of the core CPI contribution. Excluding wireless services, core inflation was roughly 0.2%. Smartphone hardware prices actually fell 1.7%. The broader telephone hardware category dropped 2.4%.

Energy prices remain a significant concern. Oil pushed back above $100 per barrel. This spike may affect airfare and consumer goods. Wage growth has decelerated for five consecutive months. Consumer sentiment hit a near-record low. Gregory Daco of EY-Parthenon noted this income squeeze is rare since 2012. The combination of high prices and stagnating wages pressures households.

Bond Yields Approach Critical Thresholds

Bond yields are rising sharply. The 10-year Treasury yield is approaching 5%. A break above this level targets 2006-2007 highs. Those highs ranged between 5.25% and 5.35%. Adam Turnquist of LPL Financial described the recent rate moves as rapid. The AI capital-expenditure boom adds pressure to credit markets. Financial conditions are tightening alongside the bond-market selloff.

Kevin Warsh faces intense scrutiny from markets. His ambiguity over the Fed’s next move increased the importance of this data. Chris Zaccarelli of Northlight Asset Management stated the Fed is now cornered. He argued that bull markets are killed by the Fed. The market’s resilience against $100 oil and high yields remains a key question. The coming week’s meeting will determine the path forward.

Market Reaction Reflects Policy Shift

Stock indices shot higher after the report. Traders interpreted the data as a clear signal for action. The AI-driven rally continues despite macroeconomic headwinds. The 85% hike probability reflects a consensus view. This shift marks a departure from previous expectations of a pause. The Fed’s stance is becoming more restrictive. Investors are adjusting their portfolios accordingly.
