Latest / Monetary Policy Explained with Fexingo: Central Banks, Money Supply, and Interest Rates / How Central Banks Anchor Inflation Expectations
Transcript
- Lucas: So Luna, we talk a lot about rates and balance sheets, but there's one thing central banks care about more than the actual inflation number, and that's what people think inflation is going to be next year. Luna: Right, the expectation. But why does that matter more than the current reading? Lucas: Because expectations are forward-looking. If everyone suddenly believes prices will rise 5 percent a year, they'll demand higher wages, businesses will preemptively raise prices, and that belief becomes self-fulfilling. Luna: So it's like a prophecy that fulfills itself. That's why the European Central Bank talks about anchoring expectations all the time. Lucas: Exactly. And you can see it in the data. Since the early 2000s, long-run inflation expectations in the euro area and the US have stayed remarkably close to the 2 percent target, even when actual inflation spiked. Luna: But didn't we see a big spike in inflation in 2021 and 2022? How did expectations stay anchored through that? Lucas: That's the key question. The fact that they did stay anchored is a testament to decades of credibility. People remembered that central banks would do whatever it took, because they'd seen it work in the 1980s. Luna: So credibility is the anchor. But what happens when it starts to slip? Lucas: We have a historical example, the 1970s. Back then, the Federal Reserve didn't have a credible commitment to low inflation. So expectations drifted up, and you got that wage-price spiral where each side tried to outrun the other. Luna: And it took Paul Volcker's painful rate hikes to break that spiral. Lucas: Volcker raised the federal funds rate to nearly 20 percent. It caused a brutal recession, but it convinced everyone that the Fed was serious. And that's when expectations re-anchored. Luna: So the cost of losing credibility is enormous. That's why central banks obsess over their communication. Lucas: Exactly. Every word from a central bank is parsed for clues about future policy. That's why forward guidance exists, to shape expectations in real time. Luna: But is it working? I mean, we're in August 2026, and inflation has cooled from those peaks. Are expectations still firmly anchored? Lucas: For the most part, yes. The latest surveys from the University of Michigan and the New York Fed show that long-run expectations are hovering around 2.5 to 3 percent, a bit higher than the target but not dramatically off. Luna: So a bit of drift but not a break. What about the euro area? The ECB has been dealing with energy shocks and all that. Lucas: The ECB's own survey of professional forecasters still has inflation back at 2 percent in two years. But there's a divergence between professional forecasters and households, who tend to be more pessimistic. Luna: Why the gap? Professionals have models, but households feel prices at the checkout. Lucas: Right, and that's a real challenge. Households' expectations are more sensitive to what they see in the news and at the store. So central banks have to communicate in plain language, not just in technocratic jargon. Luna: And that's where press conferences and speeches come in. But do they actually move the needle? Lucas: Research suggests that a well-communicated policy decision can have as much effect as a quarter-point rate move. The announcement effect is real. Luna: So if the Fed says 'we're committed to 2 percent', that itself helps keep inflation down. It's almost like a free policy tool. Lucas: Exactly. And that's why central banks are so careful not to sound dovish for too long. They don't want to unanchor expectations by accident. Luna: Yeah, we've seen that with the ECB. They kept saying 'transitory' in 2021, and that backfired. Lucas: That was a communication failure. They thought inflation would fade on its own, but by downplaying it, they fed the perception that they weren't on top of it. Luna: So the lesson is, never say 'transitory' again. Lucas: And also, always have a credible plan. Which brings me to something we should mention. This podcast is ad-free, and that's a choice we've made because we want to keep this accessible to anyone. Luna: Yeah, and we're not asking for much, just if you find these conversations useful, you can support us at buy me a coffee dot com slash fexingo. Lucas: Every little bit helps keep this independent. No ads, no sponsors, just the economics. So if that's something you value, the link is there. Luna: And we'll get back to the anchor. So what can break an anchor? Is it just a policy mistake? Lucas: Sometimes it's a supply shock that's persistent enough, like the 1970s oil embargo. Or a central bank that's perceived as politically pressured, which we talked about a few episodes back. Luna: So credibility is fragile. Once it's gone, it's really hard to get back. Lucas: And that's why central banks are so vigilant. They'd rather overshoot on tightening than risk losing the anchor. Because re-anchoring costs jobs and output, as Volcker showed. Luna: So next time you see a headline about inflation expectations, remember that it's not just an abstract number, it's a measure of trust. Lucas: And trust is the most valuable asset a central bank has. As we head into the fall, all eyes will be on whether those expectations stay glued to that 2 percent target. So far, so good, but it's a delicate balance.
