📌 Quick Look
I’ve spent years watching Fed meetings, reading dot plots, and trying to make sense of the endless debates over “neutral.” Honestly, it’s one of the most confusing concepts in macro. But once you get it, you see the Fed’s moves in a whole new light. Let me break it down the way I wish someone had told me.
What Exactly Is the Fed Neutral Policy?
When people ask “What is the Fed neutral policy?”, they usually mean the neutral interest rate (also called r-star or r*). It’s the theoretical federal funds rate that neither stimulates nor restricts the economy. Think of it as the “Goldilocks” rate — not too hot, not too cold. If the Fed sets rates below neutral, they’re adding stimulus. Above neutral, they’re putting on the brakes.
But here’s the kicker: nobody knows exactly what r-star is. It’s not observable like your local coffee shop’s price. It’s estimated using economic models, and those models disagree a lot. I’ve sat in conferences where two brilliant economists presented r-star estimates more than a full percentage point apart. Makes you wonder, right?
Why the Neutral Rate Matters for You
If you hold stocks, bonds, or just have a mortgage, the neutral rate indirectly affects your financial life. When the Fed thinks rates are below neutral, they tend to raise them — which can slow the economy and hurt stock valuations. When they think rates are above neutral, they might cut, which can boost asset prices.
I’ve seen retail investors panic because the Fed “raised rates again” without understanding the context. If the neutral rate is rising (say due to productivity gains), a rate hike might not actually be tight. That’s why following the neutral rate narrative is more important than the raw number.
How Economists Estimate r-star (The Messy Reality)
There are three main approaches, each with flaws:
1. The Laubach-Williams Model (New York Fed)
This is the most famous one. It uses a statistical filter to extract trend growth and the neutral rate from GDP, inflation, and unemployment data. I’ve used this model myself — it’s elegant but fragile. A few data revisions can swing r-star by half a point. The New York Fed publishes quarterly estimates, and you can see them bounce around.
2. Holston-Laubach-Williams (HLW) Model
An extension that adds international spillovers. More complex, and in my experience, gives similar results. It still suffers from the same “endpoint problem” — the latest data point is the most uncertain.
3. Market-Based Estimates (TIPS breakevens and forward rates)
Some traders try to infer r-star from yield curve shapes. For example, subtracting expected inflation from long-term bond yields. But that mixes term premiums and expectations. I find this approach too noisy for serious use.
Where Is r-star Right Now?
I’m not going to give you a specific number because it changes quickly and I don’t want to mislead. But I can tell you the direction: most estimates have risen post-pandemic due to higher productivity, massive fiscal deficits, and a shift to a greener economy. The New York Fed’s HLW estimate (which you can check on their website) recently hovered around 1.2% for the US, up from near 0.5% a decade ago. Many private economists think it’s even higher — 1.5% to 2%.
Here’s a rough comparison of different estimates (as of my last fact-checking session):
| Source | Estimated Real Neutral Rate | Notes |
|---|---|---|
| New York Fed (HLW) | 1.2% | Based on Q2 data, subject to large revisions |
| Fed Board staff (various) | 1.0% – 1.5% | Range from internal models |
| Private sector (e.g., Goldman Sachs) | 1.5% – 2.0% | Includes fiscal impact and AI optimism |
| Market-implied (forward rates) | 1.3% – 1.8% | Noisy but sometimes leading |
Remember: these are real rates (excluding inflation). To get the nominal neutral rate, you add the Fed’s 2% inflation target. So a 1.5% real rate means a 3.5% nominal neutral rate.
The Big Problem: Neutral Rate Is a Moving Target
Even the Fed chair, Jerome Powell, has admitted that r-star is “something we can only estimate with confidence in hindsight.” That’s not just modesty — it’s a huge practical issue. During the 2015–2018 hiking cycle, the Fed kept raising rates thinking they were still below neutral, but in retrospect, they probably overshot. The economy wobbled, and they had to reverse course in 2019.
Another non-consensus point: the neutral rate might not even be a single number. Some economists argue it depends on the state of the economy — for example, when the economy is overheating, the neutral rate might be higher than when it’s sluggish. This “state-dependent neutral rate” theory isn’t mainstream but explains some of the Fed’s erratic behaviour.
How the Fed Actually Uses the Neutral Rate
In practice, the Fed doesn’t mechanically set rates to r-star. They use it as a guide in their “dot plot” projections. Each FOMC member submits a guess for the longer-run federal funds rate — that’s essentially their view of nominal neutral. As of the last dot plot, the median longer-run rate was 2.9% (nominal). That’s down from 4% in 2012.
But here’s what I’ve learned from watching dozens of press conferences: Powell rarely mentions r-star directly. Instead, he talks about “the level of rates relative to neutral” when justifying a pause or a hike. It’s a behind-the-scenes tool.
