Federal Reserve Chairman Kevin Warsh has reintroduced monetary aggregates, particularly the M2 money supply, as a significant financial gauge in the Fed’s latest report. This move marks a renewed focus on liquidity trends amid significant growth in the money supply. In May 2026 alone, the M2 money supply jumped by $248 billion, reaching a record high of $23.1 trillion. This surge reflects patterns seen prior to 2022’s inflationary pressures. The Fed’s decision to exclude IRA/Keogh balances from M2 starting late July aims to enhance transparency in measuring liquidity.

Market participants have interpreted Warsh’s emphasis on monetary aggregates as potentially indicative of upcoming policy shifts. The pricing in relevant prediction markets suggests a heightened expectation for a rate hike at the Fed’s September meeting. Currently, the probability of a rate hike by the September meeting stands at 33.5%, up from 33% just 24 hours ago, although this is a decrease from 40% a week ago.

The Fed’s reintroduction of these measures could indicate concerns about inflationary pressures re-emerging in late 2026 to 2027. Markets are closely monitoring upcoming Fed meetings for indications of policy adjustments, particularly in light of Chairman Warsh’s focus on liquidity and money supply growth.
