The US Consumer Price Index (CPI) for August 2025 recorded a yearly increase of 2.9%, marking the highest rate since January of the same year. The prior CPI was at 2.7%, with a month-over-month increase of 0.4% against an expectation of 0.3% (an unrounded consensus of 0.36%).
Core CPI remained steady at an anticipated yearly increase of 3.1%, with a monthly rise of 0.3%. The unrounded monthly figure stood at 0.346%, reflecting a slight increase from the previous 0.228%. Real weekly earnings saw a reduction of 0.1%, compared to a previous 0.4%, later revised to 0.1%.
Core Goods And Services
Core goods prices recorded a 0.3% increase from 0.2%, while core services rose by 0.3% against a former 0.4%. Core services excluding shelter and rent showed slight reductions at 0.2% from 0.3%. Owners’ equivalent rent increased to 0.4% from the previous 0.3%. The report presents challenges in reaching targeted inflation goals, particularly amidst falling oil prices and recent increases in initial jobless claims.
With today’s inflation data coming in hotter than expected on a monthly basis, any hopes for a large 50 basis point rate cut from the Federal Reserve are now likely off the table. The unrounded core CPI figure was particularly strong, signaling that underlying price pressures remain stubborn. This suggests the Fed will need to remain cautious and data-dependent in the near term.
This persistent inflation is occurring alongside a weakening labor market, creating a difficult environment for the central bank. For instance, initial jobless claims just spiked to 265,000, the highest level we’ve seen since late 2024. This conflict between sticky inflation and rising unemployment will almost certainly lead to significant market volatility.
Impact On Trading
For traders focused on short-term interest rates, this means positions anticipating aggressive cuts need to be reconsidered. We are likely to see pressure on Fed Funds futures contracts for the upcoming meetings. The market may now price in a scenario of rates being held higher for a bit longer than previously anticipated.
Given the increased uncertainty, we expect options premiums to rise. The CBOE Volatility Index (VIX), which has been hovering around 17, could see a move back towards the 20 level, similar to the pattern we observed during the inflation fight of 2022 and 2023. This makes buying volatility through instruments like VIX calls or index straddles an attractive strategy to hedge against sharp market swings in either direction.
Further out on the curve, the market is still factoring in eventual rate cuts through 2026, driven by the softening economic data like the jobless claims. This sets up a potential yield curve steepener trade, where traders bet that long-term rates will fall faster than short-term rates. We believe the market is correctly anticipating that a slowing economy will ultimately force the Fed’s hand, but not in the immediate future.
