Once a month, a single economic data release has the capacity to reprice financial markets globally. That release is the Consumer Price Index (CPI).
The CPI measures the average change over time in the prices consumers pay for a representative basket of goods and services — encompassing food, energy, housing, transportation, and other household expenditures. It is the most widely followed indicator of inflation worldwide, primarily because it directly informs the Federal Reserve's assessment of whether its monetary policy settings are achieving their intended objectives.
The market response to CPI releases is typically systematic and well-documented. An above-consensus print — commonly referred to as a "hot" CPI — signals that inflationary pressures persist, leading markets to price in further monetary tightening. In this scenario, bond yields typically rise, fixed-income prices decline, and growth-oriented equities tend to underperform. Conversely, a below-consensus or "cool" CPI print suggests that the Fed may have scope to ease policy, prompting markets to price in rate cuts — a dynamic that generally supports risk assets across most sectors. Understanding the mechanics of CPI and the associated market reactions is essential for positioning around scheduled releases. This topic is examined in Module 6.1. Further background available here.
