U.S. Inflation Data Under Scrutiny Amid Collection Issues

A critical government report showing a slowdown in U.S. inflation last month is facing questions over its accuracy, as economists warn that data collection problems may have distorted the picture.

The Consumer Price Index (CPI), which tracks the cost of everyday goods and services, increased by 2.7% in the year to November, a figure lower than recent highs and close to the Federal Reserve's long-term target [29697][29541]. However, experts caution that this apparent cooling may be partially an illusion, stemming from disruptions caused by a recent federal government shutdown [29622][5098].

The 16-day closure prevented the Bureau of Labor Statistics (BLS) from gathering some price information as usual. To complete the report, the agency used a statistical method called "imputation" to estimate missing data for items like airline fares [29622]. Critics argue this method is flawed, as it may not have fully captured recent sharp declines in certain prices, potentially making the overall inflation rate appear lower than it truly is [29622].

This uncertainty complicates the task of the Federal Reserve (the Fed), the U.S. central bank, as it debates its next move on interest rates. The Fed is already grappling with conflicting economic signals, including a cooling labor market where job growth has slowed [27749][8382]. Policymakers are divided between officials who emphasize protecting the job market and those who prioritize the ongoing fight against inflation [8382][22286].

"The unclear picture complicates the Federal Reserve's next decision," one report noted, as officials face two uncertain signals [29697]. The central bank's goal is to engineer a "soft landing," slowing the economy enough to control prices without causing a recession [19227].

While the pace of price increases has moderated significantly from its peak, inflation itself persists, meaning costs are still rising, not falling [29378][29139]. This continues to strain household budgets, with a majority of Americans reporting that their income is not keeping up with the cost of living [29534].

The BLS has acknowledged the data issue but stands by its report's accuracy. The next inflation report, which is expected to return to normal data collection, will be watched closely to determine if November's figure reflected a true trend or a statistical anomaly [29622].
