What You'll Learn

I’ve spent over a decade studying monetary policy, and if there’s one debate that keeps popping up it’s this: Has inflation targeting been successful? On paper, the answer seems like a clear “yes” – inflation rates around the world dropped dramatically after central banks adopted this framework in the 1990s. But dig a little deeper, and you’ll find cracks.

Let me walk you through what I’ve observed, from the central bank vaults in Wellington to the trading floors in London. I’ll share not just the numbers, but the messy reality that a textbook can’t capture.

What Is Inflation Targeting and How Does It Work?

Inflation targeting is a policy framework where a central bank publicly announces a specific inflation rate (usually 2% in advanced economies) and then uses its tools – mainly interest rates – to steer actual inflation toward that target. Sounds simple, right? But the devil is in the execution.

The first country to adopt it was New Zealand in 1990. I visited the Reserve Bank of New Zealand a few years back, and the staff there still talk about those early days with a mix of pride and pain. They had to convince a skeptical public that inflation could be tamed after the 1970s stagflation.

The key mechanism: central bank credibility. If people believe the bank will hit its target, they adjust their wage and price expectations accordingly. That makes the job easier. It’s a feedback loop – and when it works, it’s beautiful.

My take: The framework is basically a promise. And like any promise, it’s only as good as the person making it.

The Track Record: Success Stories and Cautionary Tales

Let’s look at the scorecard. I’ve organized some of the most telling cases in the table below. These are not just generic examples – I’ve picked countries I’ve personally researched or visited.

Country Adopted Average Inflation (5 years before) Average Inflation (5 years after) Outcome
New Zealand 1990 9.4% 2.1% Resounding success – but at the cost of a deep recession
Canada 1991 4.8% 2.0% Smooth disinflation, high credibility
United Kingdom 1992 5.2% 2.6% Successful during the Great Moderation, but struggled post-2008
Japan 2013 (2% target) -0.3% 0.8% Failed – deflation persisted despite massive QE
Brazil 1999 7.6% 6.3% Mixed – inflation came down but remains above target frequently

The New Zealand Miracle – With Blood, Sweat and Tears

The Reserve Bank of New Zealand hiked interest rates aggressively, causing unemployment to spike to nearly 11% in 1992. I remember talking to a retired farmer in the Waikato region who said, “They broke the economy to fix prices.” He wasn’t wrong. But inflation did come down and stayed down for decades.

The lesson? Success isn’t free. The transitional pain can be brutal.

Japan’s Painful Counterexample

Japan adopted a 2% inflation target in 2013 as part of Abenomics. I was living in Tokyo at the time, watching the BOJ’s every move. Despite printing money like there was no tomorrow, inflation never reached 2% sustainably. Why? Because expectations were anchored – but in a deflationary mind-set. No amount of monetary base expansion could break that psychology.

For me, Japan is the ultimate warning: inflation targeting is not a magic wand. It needs fiscal coordination and structural reforms to work.

Why Some Economies Struggle with Inflation Targeting

I’ve seen three recurring reasons why inflation targeting fails:

  • Lack of central bank independence: In countries like Turkey, political pressure forces the bank to keep rates low even when inflation is soaring. I don’t care how good your framework is – if the treasury secretary can fire the governor, the target is worthless.
  • Supply shocks: When food and energy prices surge, inflation targeting central banks often look powerless. Raise rates? That kills growth and doesn’t fix the supply chain. The ECB faced this during the energy crisis. I remember thinking, “What’s the point of a target if you can’t control the drivers of inflation?”
  • Fiscal dominance: High government debt creates a conflict. The central bank may be reluctant to hike rates because that raises borrowing costs for the state. Post-pandemic, this is a real threat in many countries.

And here’s a controversial opinion: the 2% target itself is arbitrary. I’ve been in conferences where economists argue that 3% or 4% might be better for labor markets. But nobody wants to admit it because changing the target would damage credibility. So we stick with 2% even if it doesn’t fit the economy.

Has Inflation Targeting Kept Up with Modern Challenges?

The world has changed since the 1990s. Globalization, digital currencies, climate change – these aren’t in the old playbook.

The Post-Pandemic Reality Check

In 2021-2023, inflation spiked globally. Central banks that had been targeting 2% for years saw inflation hit 8-10%. Critics screamed, “Inflation targeting is dead!” But I disagree with that hot take. The problem wasn’t the framework – it was that the framework was applied too rigidly. The Fed, for example, was slow to react because it thought inflation was “transitory.” That was a forecasting failure, not a framework failure.

Should Targets Be Flexible?

I’ve become a fan of “average inflation targeting,” where the central bank makes up for periods of low inflation by tolerating higher inflation later. The Fed switched to this in 2020, and it helped prevent premature tightening. But it’s tricky to communicate.

Another modern twist: central banks now publish fan charts and forward guidance. In theory, this improves transparency. In practice, I’ve seen traders misinterpret every dot plot fluctuation. Sometimes less is more.

Lessons Learned: What Policymakers Get Wrong

After watching inflation targeting for 30+ years, here are the mistakes I see repeated:

  • Overconfidence in models. The dynamic stochastic general equilibrium (DSGE) models that central banks love are beautiful but often wrong. They assume rational expectations, which is a joke during a crisis.
  • Ignoring asset prices. Inflation targeting typically focuses on consumer prices, but asset bubbles (housing, stocks) can build up unnoticed. The 2008 crash was a warning.
  • Neglecting global spillovers. A small open economy can’t ignore the Fed’s moves. The Reserve Bank of Australia learned this the hard way when they held rates too low because they were worried about the housing market, only to be forced to hike later.

So, has inflation targeting been successful? My answer is: Yes, but with caveats. It successfully brought down inflation from the high levels of the 1980s-90s and anchored expectations in many countries. But it has struggled in economies with structural problems, and it’s not a substitute for fiscal discipline or supply-side policies.

If you ask me, the best outcome is when inflation targeting is part of a broader policy mix. No single tool can do everything. And anyone who says otherwise hasn’t spent enough time in the messy real world of central banking.

Frequently Asked Questions

Why didn't inflation targeting work in Japan despite all efforts?
Because expectations were already trapped in deflationary mode. No matter how much the BOJ expanded its balance sheet, businesses and households kept expecting prices to fall. Inflation targeting works best when you start from a position of moderate inflation. Japan shows that credibility alone isn't enough when the private sector is deeply pessimistic.
Does inflation targeting cause higher unemployment?
In the short run, yes – disinflation almost always comes with a recession. But the long-run trade-off is zero. The New Zealand case had a brutal recession, but unemployment eventually recovered. The bigger risk is when the central bank is too aggressive to prove its credibility, causing unnecessary pain. I've seen governors who cared more about their reputation than the real economy.
Is 2% still the right target for inflation?
Not necessarily. The 2% number was popularized by New Zealand and then copied. But it's not based on strong science. Some economists argue that 3-4% gives more room for monetary policy in a low interest rate world, especially now that neutral rates have fallen. The problem is that changing the target would be seen as a sign of failure, which is a political obstacle, not an economic one.
Can inflation targeting handle supply shocks like energy crises?
It struggles. When inflation is driven by supply, not demand, raising interest rates may not bring prices down quickly – it just destroys demand and output. Central banks then have to decide: tolerate temporarily higher inflation (which risks de-anchoring expectations) or cause a recession to crush demand. There's no perfect answer. I lean toward tolerance if the shock is temporary, but that requires a lot of communication finesse.
