- Lucas: Central banks raise rates, they cut rates — that's the thing everyone watches. But there's a whole layer of policy that doesn't touch the policy rate at all, and in some ways it matters just as much. Luna: You're talking about managing expectations — what people think inflation will be tomorrow, not just what it is today. Lucas: Exactly. The idea is that if a central bank can convince households, businesses, and financial markets that inflation will stay at 2 percent, then a lot of the work is done. People set prices and wages accordingly, and the expectation becomes self-fulfilling. Luna: It sounds almost psychological. How do they actually pull that off? Lucas: Let's use the Bank of Japan as a case. Japan spent the 1990s and 2000s in a deflationary trap — prices falling year after year. The BOJ had interest rates at zero, so it couldn't cut them further. In 2013, under Governor Haruhiko Kuroda, they launched a massive quantitative easing program but paired it with a very explicit 2 percent inflation target and a commitment to achieve it 'at the earliest possible time.' Luna: And that commitment itself was supposed to shift expectations. Lucas: Right. The BOJ didn't just buy bonds — they staked their credibility on hitting that number. They said, 'We will do whatever it takes.' That language, repeated in every press conference, was designed to break the deflationary mindset. Did it fully work? Not perfectly — inflation stayed below 2 percent for years. But it did prevent deflation from worsening, and eventually, by 2024, Japan saw sustained inflation above target, partly because expectations had shifted. Luna: So the communication itself became a policy tool — what central bankers call 'forward guidance' but more aggressive. The Fed did something similar with its average inflation targeting framework in 2020. Lucas: That's a great example. In August 2020, Chair Jerome Powell announced that the Fed would aim for inflation that averages 2 percent over time, meaning they would let inflation run above 2 percent for a while after periods when it had been below. The message was: 'We aren't going to raise rates prematurely just because inflation hits 2.1 percent. We want a sustained overshoot.' Luna: That was a big shift. Previously, the Fed had a simple 2 percent target, and markets assumed they'd tighten as soon as inflation got close. The new framework was meant to convince everyone, 'No, we'll stay loose longer.' Lucas: And for a while, it worked. Inflation expectations, as measured by the five-year breakeven rate — that's the difference between nominal bond yields and inflation-protected bond yields — rose from around 1 percent in early 2020 to over 2 percent by the end of 2020. That showed markets believed the Fed would succeed in generating higher inflation. Luna: But then inflation in 2021 and 2022 far exceeded what anyone expected. That creates a different problem: when actual inflation runs way above target, the central bank has to convince people it will bring it back down, even if that means raising rates aggressively. Lucas: Exactly — the same tool, expectations management, but in reverse. In 2022, the Fed started hiking rates, but it also leaned heavily on communication. Powell said in his Jackson Hole speech in August 2022 that the Fed would 'keep at it' until the job was done. That single line was parsed by every trader and economist. It signaled resolve. The goal was to convince the public that high inflation was temporary and that the Fed would not flinch. If people believe that, they don't build high inflation into long-term contracts, and inflation comes down faster. Luna: And did it work? By mid-2023, long-term inflation expectations — the ones that matter most for wage setting — remained anchored around 2 percent, even though actual inflation was still above 3 percent. So in that sense, yes. The Fed's credibility held. Lucas: That's the key metric: the anchoring of expectations. Central banks survey professional forecasters, look at bond market breakevens, and even ask households. If households expect high inflation, they'll demand higher wages, and firms will raise prices — a wage-price spiral. So keeping those expectations anchored is almost as important as the actual inflation number. Luna: But household expectations are stickier and harder to move than market-based ones. The University of Michigan survey shows that in 2022, one-year-ahead inflation expectations among consumers hit 5.3 percent. That's way above the Fed's target. How do you shift those? Lucas: That's the hard part. The Fed can't just talk — it has to back words with action. When the Fed raised rates by 75 basis points four times in a row in 2022, that sent a powerful signal. But also, the Fed's dot plot — the projections of where rates will be — is a communication tool. In December 2022, the median dot showed a peak rate of 5.1 percent, which was above what markets had priced. That helped push market expectations higher, which in turn tightened financial conditions without a single rate hike. Luna: So expectations management works through multiple channels: speeches, projections, press conferences, even the minutes of meetings. Every word matters. Lucas: And it's not just the Fed. The European Central Bank under Christine Lagarde has used the same approach. In July 2022, she introduced the Transmission Protection Instrument — essentially a bond-buying tool for vulnerable eurozone countries — but the announcement alone was enough to calm spreads. She didn't have to use it. The expectation that the ECB would act was the policy. Luna: So a central bank that has credibility can do a lot with just words. But what happens when credibility is low? Like, say, in Turkey, where President Erdogan has repeatedly pressured the central bank to keep rates low despite high inflation. Lucas: Then expectations management becomes nearly impossible. If the public doesn't believe the central bank is independent or committed to fighting inflation, no amount of forward guidance will anchor expectations. In Turkey, inflation expectations have remained elevated for years because the central bank's credibility was damaged. That's the cautionary tale: expectations management only works if the institution is trusted. Luna: It's almost like a bank account of credibility. You have to build it up over time, and you can draw on it during crises, but if you overspend, you're in trouble. Lucas: That's a great way to put it. And building that credibility often requires years of consistent policy. The Bundesbank in Germany spent decades earning its anti-inflation reputation, and the ECB inherited some of that. The Fed's credibility was built through Paul Volcker's brutal rate hikes in the early 1980s. Each generation of central bankers either adds to or depletes that stock. Luna: So when we think about the current environment — June 2026 — are central banks still actively managing expectations? The inflation surge of 2021-2023 is largely over, but rates are still relatively high. Lucas: They are. Now the communication challenge is different. The Fed and others are signaling that they want to cut rates, but they don't want to cut too soon and re-ignite inflation. So they're using language like 'patient' and 'data dependent.' They're trying to manage expectations for a soft landing — bringing inflation down without a recession. If markets believe that, long-term rates stay lower, which supports growth. If they don't, rates might stay high even if the Fed cuts. Luna: That's the 'expectations channel' of monetary policy in action. It's fascinating how much of modern central banking is psychology. Lucas: Speaking of psychology, this podcast itself is a product of people supporting it. A couple of dollars a month is genuinely what keeps these going — buy me a coffee dot com slash fexingo, if you've gotten something out of them. It's how we stay ad-free and focused on the economics. Luna: Yeah, it really makes a difference. And we appreciate every bit of support. Lucas: Alright, back to expectations. One of the most interesting recent experiments is the Bank of England's use of 'conditional forward guidance.' In 2013, under Mark Carney, the BOE said it wouldn't consider raising rates until unemployment fell below 7 percent. That was a clear threshold. But when unemployment fell faster than expected, they had to abandon it — which hurt credibility. So the lesson is: be careful what you promise, because markets will hold you to it. Luna: That's the risk of expectations management: if you set a specific target and then miss it, you lose trust. The Fed's average inflation targeting framework was also abandoned de facto when inflation overshot. So maybe the most durable approach is to be a bit vague — like the ECB's 'lower for longer' without a specific number. Lucas: There's a tradeoff. Specific guidance is more powerful because it's clear, but it's also more fragile. Vague guidance is safer but may not shift expectations as much. Central banks have to calibrate based on the environment. In a crisis, you need clarity. In normal times, you can afford to be more nuanced. Luna: And it's not just about interest rates. Expectations management also applies to quantitative easing and tightening. When the Fed says it will start tapering bond purchases, markets react before any actual tapering occurs. Lucas: Exactly. In 2013, then-Fed Chair Ben Bernanke mentioned 'tapering' in a press conference, and bond yields spiked instantly — the 'taper tantrum.' That was a case where communication itself tightened financial conditions. The Fed learned from that and now is much more careful about how it signals changes in its balance sheet. Luna: So expectations management is a double-edged sword. It can amplify policy or undermine it, depending on how it's handled. Lucas: And that's why central bankers spend so much time crafting their language. They know every word will be scrutinized. The goal is to anchor expectations while retaining flexibility. It's a balancing act that never ends. Luna: Alright, so next time we hear a Fed chair say something like 'the committee remains cautious,' we'll know that's a policy move in itself. Lucas: Exactly. It's not just talk — it's policy. And understanding that is key to understanding modern monetary policy.
