PlusUS inflation (CPI)
Why it matters in the US
In general
Inflation is how fast money loses buying power. When it runs hot, the Fed tends to keep rates higher, and loans and savings follow.
How markets usually react
US stocks usually have a normal day on US CPI days
Big swings, when the S&P 500 rises or falls 1% or more in a day, are about as common on US CPI days as on any other day.
Last time, on Oct 14, 2026, the S&P 500 had a big swing: it fell 1.1%.
US interest rates tend to swing more on US CPI days
The 10-year US Treasury rate, which many loan rates follow, moved 0.1 percentage points or more on about 1 in 9 US CPI days, and on about 1 in 14 other days.
Looking back at 119 US CPI days since 2016. History, not a prediction.
