Recent September CPI data, showing core inflation accelerating to 2.6% year-over-year from 2.4% in August amid broad-based gains in shelter, services, and core goods, anchors trader expectations for the October reading. Persistent energy price pressures from geopolitical tensions, combined with firm supercore components and limited progress in disinflation, support market-implied odds clustering around 2.5-2.6%. The Federal Reserve's recent communications and September dot plot, signaling potential additional rate hikes by year-end to address upside inflation risks, reinforce this consensus. Upcoming labor market and PPI releases, along with the late-October FOMC meeting, represent key near-term catalysts that could shift probabilities if they reveal further broadening of price pressures or signs of moderation.
