Key catalysts include Federal Reserve policy decisions and forward guidance on interest rates, which influence inflation expectations and wage-price dynamics. Energy and commodity price movements, supply-chain disruptions, and labor market strength all feed into core inflation momentum. Consumer spending patterns, housing costs, and service-sector pricing power are critical components of core CPI. Unexpected economic data—employment reports, retail sales, producer prices—can shift trader expectations about inflation trajectory. Geopolitical events or trade policy changes may also move markets by altering inflation forecasts heading into July 2026.
