The Federal Reserve’s medium-run natural interest rate is estimated at 1.5%, a key benchmark for monetary policy as officials weigh future rate adjustments.

The real natural rate of interest—the inflation-adjusted level consistent with full economic capacity—is currently estimated at approximately 1.5% [1]. This benchmark serves as a critical guide for the Federal Reserve, as policy is considered accommodative when the real federal funds rate falls below this level and restrictive when it exceeds it [1].

| At a glance | |
|---|---|
| Medium-run natural rate | 1.5% |
| Policy stance | Accommodative |
| Estimation horizon | Medium-run (up to 5 years) |
| Primary benchmark | Real federal funds rate |

## Assessing the natural rate
The natural rate of interest is not directly observable and must be estimated, leading to significant variance depending on the time horizon used [1]. While long-run measures like the Holston, Laubach, and Williams (HLW) "r-star" provide a stable trend, they often smooth over transitory economic shocks [1]. In contrast, a new medium-run measure proposed in recent research captures both persistent economic pressures and significant short-term shifts, such as those experienced during the 2020 pandemic [1].

Data from 1987 through the fourth quarter of 2025 indicates that this medium-run measure is more responsive to business cycle troughs than traditional long-run models [1]. During the 2008 financial crisis, the medium-run natural rate fell nearly 5 percentage points, while the pandemic period saw a drop of nearly 4 percentage points [1]. By incorporating these fluctuations, the medium-run estimate aims to provide a more timely signal for policy adjustments before economic pressures fully materialize in inflation or unemployment data [1].

## Policy implications and uncertainty
Despite the utility of the 1.5% estimate, uncertainty regarding the natural rate remains high [1]. Because the rate is an empirical estimate rather than a fixed observation, inaccurate readings risk leading policymakers to steer the economy too aggressively or insufficiently [1]. 

The Federal Reserve’s current stance is characterized as accommodative because the real federal funds rate remains below this 1.5% natural rate threshold [1]. While the medium-run measure is designed to filter out excessive volatility, it remains a model-based projection subject to the inherent challenges of forecasting economic conditions [1].

## What to watch
*   **Future revisions:** Monitor updates to the medium-run natural rate estimate, as high uncertainty bands suggest the 1.5% figure could shift with incoming data on inflation and economic growth [1].
*   **Policy divergence:** Observe how the Federal Open Market Committee (FOMC) balances the medium-run natural rate against traditional long-run benchmarks when determining the path of the federal funds rate [1].
*   **Economic shocks:** Watch for how the medium-run measure reacts to future transitory economic disruptions, which may signal a need for rate adjustments that longer-horizon models might overlook [1].

The reliance on a medium-run natural rate represents an attempt to improve the precision of monetary policy by using "sonar" to detect underlying demand pressures rather than reacting only to visible inflation data [1]. Whether this approach successfully stabilizes the economy depends on the accuracy of these estimates in an environment where the natural rate remains inherently volatile [1].
