The overall U.S. CPI report for December meets expectations, but some month-on-month data may be distorted.

The overall December CPI report was highly consistent with economists' predictions, with prices rising by 0.3% on a month-on-month basis and by 2.7% year-on-year. In terms of structure, prices of core goods remained stable. Among them, the increase in clothing prices was offset by the decrease in prices of used cars and the stability of new car prices in December. Core service prices rose by 0.3% on a month-on-month basis in December. Specifically, housing costs rose by 0.4%, medical service prices rose by 0.4%, and transportation service prices rose by 0.5%. It is worth noting that airline ticket prices saw a significant increase of 5.2% in December. However, due to data collection issues caused by the government shutdown at the end of last year, some month-on-month data comparisons between November and December may be distorted.
