M2 Peaking as Reverse Repo Drains to ZeroThe reverse repo balance at the Fed represents trapped liquidity. When this balance comes down it means liquidity is released into the economy and markets. The M2 level lags the change in reverse repo by about 300 days. Because reverse repo changes have been steady for some time, it is possible to draw a trajectory for reverse repo going to zero, and then M2 peaking out. This would coincide with a potential topping process for SPX as shown in the lower pane of the chart.
