The Fed’s Inflation Blind Spot: How Outdated Metrics Lead to Missteps

(SeaPRwire) –   By: Raymond Vance, a senior macro-economist and consultant to central banking policy research working groups

The Federal Reserve’s approach to inflation measurement has long been a subject of debate. Relying heavily on 12 – month summaries, the Fed often makes monetary policy decisions based on past economic data. This backward – looking strategy can obscure current trends and lead to delayed or inappropriate responses.

The July Consumer Price Index (CPI) came in at 3.4%, slightly down from June’s 3.5% but still well above the Fed’s 2% target. This figure has raised concerns among some Fed officials. At the latest Federal Open Market Committee meeting, three regional Fed branch presidents voted to increase interest rates immediately. Beth Hammack of the Cleveland Fed warned of the challenges of taming long – lasting high inflation, and Neel Kashkari of the Minneapolis Fed worried about inflation becoming entrenched. Chairman Warsh also emphasized the need to fight inflation and reach the 2% target.

However, a closer look at the data reveals a different story. The 3.4% CPI is a Year – over – Year (YoY) comparison, which shows price increases over the past 12 months. In contrast, the 3 – month average of the CPI since May, annualized, is just 0.49%. The Producer Price Index (PPI), reported this week, was up 4.7%. But on a monthly basis, it has been falling rapidly since April and was negative in June and July, with a 3 – month annualized rate of 1.6%. Inflation expectations have also moderated significantly since May, with market measures and the Cleveland Fed’s model forecasting inflation in the 2.3% range, well below the headline CPI.

The market seems to be taking note. The S&P 500 hit a new record after the CPI release, and the market consensus on a possible September rate increase flipped. Many economists, including Nobelist Paul Krugman and Jason Furman, support the use of shorter – term inflation measures. They argue that in a volatile economy, looking at 3 – to 6 – month changes can provide a more accurate picture of inflation trends.

The Fed’s reliance on backward – looking data has had negative impacts on monetary policy. It obscures critical turning points in the inflation trend and exacerbates the lag in responding to changes. Consider the 2021 – 2023 inflation spike. The annualized 3 – month data shows that the inflation trend changed abruptly in mid – 2022, dropping from 10.1% to 1.9% in a single quarter. The standard CPI first understated and then overstated this short – run inflation measure. By the time the Fed started raising rates in mid – 2022, the inflationary surge was already ending.

Milton Friedman’s concept of a “long and variable lag” in monetary policy is relevant here. Fed officials have widely endorsed this idea. The inflation episode began in 2020/2021, rate hikes started in March 2022, but the policy may only have started to impact the economy in late 2023 or 2024, long after inflation had materially declined.

The Fed’s current inflation measurement methods are causing it to misread the economic situation. To make more effective monetary policy decisions, the Fed should place greater emphasis on shorter – term inflation measures. This shift could help the Fed respond more promptly to inflation changes and avoid the pitfalls of its current backward – looking approach.
