Fed Shifts Focus to Money Supply in Inflation Evaluation

The Federal Reserve has shifted its focus to money supply in evaluating inflation, revisiting a tool it had largely shelved for decades. The central bank's July 2026 Monetary Policy Report highlighted the importance of M2 trends in relation to inflation and liquidity metrics.

US M2 money supply stands at approximately $23.16 trillion, with year-over-year growth ranging between 4-5%. This moderate growth rate is similar to patterns observed during the 2010s, a period characterized by subdued inflation.

The Fed's renewed emphasis on M2 metrics marks a departure from its previous reliance on interest rates as the primary steering wheel. Historically, money supply aggregates like M2 were closely monitored, particularly during the 1970s and early 1980s. However, this focus diminished as the relationship between money supply growth and inflation weakened.
