Why the Fed is often slow, late … and wrong in reading inflation

The Federal Reserve tends to rely on past economic data when determining monetary policy rather than present or future data. This is because the Fed uses economic measures that summarize the previous 12 months to gauge inflation. For instance, the July Consumer Price Index stood at 3.4%, which is below the June figure of 3.5% and remains far above the Fed's 2% target.

However, the slowdown in reporting these figures can make it difficult for the Fed to accurately gauge current inflation rates. The Cleveland Fed's 3-month annualized Consumer Price Index, for instance, was just 0.49%. Producer Price Index, which tracks the cost of goods at the wholesale level, skyrocketed by 4.7% in July, suggesting a looming increase in consumer prices.

Despite this, inflation expectations have moderated significantly since May, with both market measures and the Cleveland Fed's model projecting inflation in the 2.3% range. This discrepancy in inflation data could suggest that inflation may have already reached the Fed's 2% target, at least on a short-run basis. The Federal Reserve's strategy has been to focus on larger, year-over-year figures, which can be slow to reflect rapid changes in inflation. This approach may be a hindrance in effectively responding to inflation trends.
