Latest / Monetary Policy Explained with Fexingo: Central Banks, Money Supply, and Interest Rates / Why Central Banks Are Watching the Labour Force Participation Rate
Transcript
- Lucas: If you've been following central bank commentary over the past couple of years, you've probably noticed a specific statistic popping up again and again: the labor force participation rate. Not just the unemployment rate, not just job creation numbers, but the share of people actually in the workforce or actively looking for work. Luna: Right. And it's become a real obsession for policymakers. But why? Isn't the unemployment rate the headline number everyone watches? Lucas: Well, the unemployment rate can be misleading. If people drop out of the labor force entirely, they're no longer counted as unemployed. So a falling unemployment rate could actually hide a weakening economy if participation is shrinking. That's why central banks now watch LFPR as a measure of labor market slack — and as a signal for wage inflation. Luna: So it's like a canary for whether the economy can grow without overheating. Lucas: Exactly. Let's take a concrete example. In the U.S., prime-age participation — that's workers aged 25 to 54 — fell from about 83 percent in early 2020 to around 81.5 percent during the pandemic's peak disruption. A lot of people left the workforce, and there was genuine fear they might never come back. Luna: And that would have permanently reduced the economy's capacity to produce goods and services — pushing up inflation if demand stayed strong. Lucas: Precisely. But what actually happened surprised many economists. By mid-2025, prime-age participation had rebounded to over 83 percent, even exceeding pre-pandemic levels in some months. That recovery has been a key factor in the Federal Reserve's ability to keep rates on hold without triggering a wage-price spiral. Luna: So the participation rebound effectively gave the economy more room to run. More workers meant more supply, which took pressure off wages and prices. Lucas: Right. And that's the core insight: central banks aren't just looking at the headline participation number. They're decomposing it by age, gender, and education to understand where the slack really is. For example, the participation rate for women with children under six has risen sharply since 2020, partly due to remote work flexibility. That's a structural shift that could keep labor supply higher for years. Luna: But some of the recovery might be temporary, right? I mean, aging demographics are a long-term drag. The baby boomer retirement wave isn't reversing. Lucas: That's the key debate. The Fed's models estimate that the trend participation rate — adjusted for demographics — is still lower than where we are today. So some of the current strength could fade as the population ages. But the prime-age group, which is less affected by retirement, has shown remarkable resilience. The question is whether that can offset the demographic headwind. Luna: And this matters for the neutral rate of interest — r-star. If participation stays high, potential output grows, and the neutral rate could be higher than previously thought. Lucas: Exactly. Many central banks now incorporate participation forecasts directly into their r-star estimates. The Bank of Canada and the Reserve Bank of Australia have published research showing that incorporating prime-age participation improved their inflation forecasts by about 10 to 15 percent in recent years. That's significant. Luna: So it's not just an academic exercise. It feeds into real policy decisions. Lucas: Right. For instance, in 2023, some Fed officials argued that the participation rebound meant the economy could sustain a lower unemployment rate without inflation picking up. That helped them justify pausing rate hikes. If participation had stayed depressed, they might have tightened more aggressively. Luna: So watching LFPR gives central banks a forward-looking gauge of how much slack is actually left in the labor market — beyond just the unemployment rate. Lucas: Exactly. And it's not just the level, but the flow. Central banks now track transitions in and out of the labor force. For example, if people are moving from 'not in labor force' directly into employment — skipping unemployment — that signals tightness. If they're moving into unemployment first, that signals softening. Luna: That's a much richer picture than a single number. But doesn't it also create a lot of uncertainty for policymakers? I mean, participation rates are notoriously hard to predict. Lucas: Absolutely. That's the other side. The Fed's own staff have missed participation forecasts by wide margins. In 2021, they predicted participation would not return to pre-pandemic levels until 2025 at the earliest. It actually happened by 2023. So you have to take these models with a grain of salt. Luna: But the fact that they're using them at all shows how central banks have evolved since the 2008 crisis. They're much more data-driven and willing to drill into specific demographics. Lucas: No question. And this brings us to a broader point: central banks are now treating the labor market as a leading indicator for inflation, not just a lagging one. The participation rate is at the center of that shift. If you want to understand where policy is headed, watch the participation data. Luna: Speaking of understanding where things are headed, this is exactly the kind of economic insight that keeps this show ad-free and listener-supported. If walking through these concepts with us has made something click, there's a simple way to help us keep doing it. Lucas: Yeah, it's at buy me a coffee dot com slash fexingo. No pressure, just a way for listeners who find value in these deep dives to chip in. We keep it ad-free so we can go wherever the data takes us. Luna: And right now, the data is telling us that participation rates in other advanced economies are diverging. Japan's prime-age participation has been climbing for years, while the euro area's has stagnated. Lucas: That's a great point. The ECB is actually more concerned about structural participation shortfalls than the Fed, because Europe's aging is more advanced in some countries. The Bank of Japan, on the other hand, has seen participation rise due to women and older workers staying in the workforce longer. That's given them more room to normalize policy. Luna: So the same metric tells different stories in different economies. It's not just about the number — it's about the context. Lucas: Exactly. And that's why central banks will keep refining their models. The participation rate is like a window into the future labor supply, and that determines how much the economy can grow without generating inflation. It's one of the most important numbers you rarely hear about. Luna: And one of the trickiest to interpret. But at least now we know what to look for. Lucas: Next time you see a Fed press conference, listen for the word 'participation.' It'll tell you a lot about where they think the economy is heading.
