• A top economist at the Miran Group argues that the neutral interest rate is being structurally suppressed by fiscal stimulus and labor force growth.
  • This assessment suggests central banks may have more room to cut rates without reigniting inflation than previously thought.
  • The view is gaining traction among some policymakers as they weigh the timing of a policy pivot.

A senior economist at financial services firm Miran has articulated a view that is increasingly shaping market expectations: the neutral rate of interest is being pushed lower, creating a pathway for more aggressive monetary easing. The argument, detailed in an internal memo reviewed by this publication, posits that recent expansionary tax policy and a surge in immigration are fundamentally altering the macroeconomic landscape.

The neutral rate—the theoretical level at which monetary policy is neither stimulative nor restrictive—has long been a subject of intense debate. Miran's analysis suggests that government tax measures have boosted disposable income and aggregate demand, while simultaneously, strong immigration flows have rapidly expanded the labor supply. This combination, the memo argues, is increasing the economy's potential output, thereby lowering the equilibrium interest rate.

"The calculus for central banks is shifting," the memo states, according to a person familiar with its contents. "The old estimates of neutral may no longer apply. The implication is that policy could be more restrictive than intended at current settings, warranting an earlier and potentially steeper normalization path."

This perspective is gaining a hearing within key institutions. Officials at the Federal Reserve and the European Central Bank have recently acknowledged that immigration-driven labor force growth is helping to cool wage pressures, a critical factor in their inflation fight. The Miran view adds a fiscal dimension to this analysis, suggesting that tax policy is working in concert with demographic trends.

Market participants are already adjusting their bets. Futures pricing now implies a greater probability of rate cuts beginning in the third quarter, with some traders anticipating a total of 50 basis points of easing by year-end. When reached for comment, a spokesperson for Miran declined to elaborate on the internal assessment.

Not all economists are convinced, however. Some warn that persistent fiscal deficits could ultimately be inflationary, forcing central banks to keep rates higher for longer. The debate hinges on whether the supply-side benefits from a larger workforce can fully offset the demand-side stimulus from government spending.

For now, the Miran thesis provides a coherent narrative for investors anticipating a dovish pivot. All eyes will be on upcoming employment and inflation data to see if the real economy aligns with this emerging view of a lower neutral rate.
