After twenty years of deflation, Japan is finally in an inflationary upcycle
For the first time in a generation, Japan is stepping out of the long shadow cast by economic crisis. The Bank of Japan raised its policy rate to 1 percent on Tuesday — the highest since 1995 — marking another deliberate move away from the emergency monetary posture that defined the nation for three decades. Driven by rising global energy prices and accelerating wholesale inflation, the central bank is attempting something quietly profound: the normalization of an economy that once forgot what normal felt like.
- Japan's wholesale prices surged 6% year-over-year in May — the fastest pace in three years — signaling that the era of deflation has given way to a new inflationary pressure the BOJ can no longer ignore.
- The rate hike to 1% is only the second increase since December, yet it represents a seismic philosophical break from two decades of near-zero emergency policy that had become the country's economic default.
- Governor Kazuo Ueda was hospitalized and missed the meeting entirely, yet the decision held — a sign that the shift toward normalization has become institutional, not merely personal.
- Higher borrowing costs now threaten to squeeze a heavily indebted government and slow business investment, forcing the BOJ to walk a razor's edge between cooling inflation and choking growth.
- A stronger yen is emerging as a quiet dividend of the hike, making the currency more attractive to global investors — a stabilizing signal in an economy long battered by currency weakness.
Japan's central bank raised its policy rate to 1 percent on Tuesday, the highest level since 1995, continuing a gradual retreat from the emergency monetary policy that has defined the country for three decades. The move follows a December hike and traces back to March 2024, when the Bank of Japan lifted rates for the first time in seventeen years.
The backdrop is a country that spent the 1990s and much of the 2000s in economic hibernation — asset prices collapsed, deflation took hold, and near-zero rates became not a temporary fix but a permanent condition. What has changed is the world around Japan. Global energy prices have spiked, and Japan, heavily dependent on imported oil and gas, has felt the strain acutely. Wholesale prices rose more than 6 percent in May compared to a year earlier. Even so, overall inflation sits at just 1.4 percent — still below the BOJ's 2 percent target — leaving the bank navigating between the need to act and the risk of overreaching.
Economist Jesper Koll told the BBC that Japan has genuinely exited its deflationary era and entered an inflationary upcycle, meaning the central bank can finally operate without a crisis mandate. That argument carried the day even in the absence of Governor Kazuo Ueda, who was hospitalized with a liver cyst and missed the meeting — a striking detail that underscored how institutionalized the shift has become.
The rate increase also serves a secondary purpose: supporting the yen, which has weakened against the dollar and euro. Higher rates make the currency more attractive to investors. Politically, Prime Minister Sanae Takaichi — historically a proponent of government spending and skeptical of rate hikes — has not moved to block the BOJ's course. With the US and UK both holding rates above 3 percent, Japan's ascent from near-zero remains a long road, but it is now unmistakably underway.
Japan's central bank took another step away from the monetary policy that has defined the nation for three decades. On Tuesday, the Bank of Japan raised its policy rate to 1 percent, climbing from 0.75 percent—the highest level the country has seen since 1995. The move reflects a fundamental shift in how the bank approaches its economy, one that has been unfolding gradually since March 2024, when officials lifted rates for the first time in seventeen years.
For context, Japan spent the 1990s and the two decades that followed in a kind of economic hibernation. Asset prices—property, stocks—had collapsed, and the central bank responded by cutting rates aggressively and keeping them near zero as the country battled deflation and stagnation. That emergency footing lasted so long it became normal. But the world has changed. Global energy prices have spiked, particularly after the Iran war, and Japan, which depends heavily on imported oil and gas from the Middle East, has felt the pressure acutely. Wholesale prices climbed more than 6 percent in May compared to a year earlier, the fastest pace in three years.
Yet the picture remains complicated. Japan's overall inflation rate sits at 1.4 percent as of April, still below the central bank's 2 percent target. The BOJ is caught between two competing pressures: raising rates to cool inflation, which makes borrowing more expensive for both government and businesses, or holding steady to avoid strangling growth. Jesper Koll, an economist who studies Japan, told the BBC that the country has finally emerged from two decades of deflation and entered what he calls an inflationary upcycle. The central bank, he said, no longer needs to operate in crisis mode. It can return to normal monetary policy.
The timing of this week's decision carried an unusual wrinkle. Kazuo Ueda, the bank's governor and a key voice in rate decisions, was hospitalized with an infected liver cyst and missed the meeting. Yet his absence did not change the outcome. Ueda and other policymakers have signaled in recent months that they see merit in raising rates if inflation risks outweigh concerns about economic slowdown. The decision also serves another purpose: it helps stabilize the yen, which has weakened against major currencies like the dollar and the euro. A higher interest rate makes holding yen more attractive to investors, supporting the currency.
Politically, the move carries weight. Prime Minister Sanae Takaichi, who took office last year, has historically favored increased government spending and has been skeptical of rate hikes. Yet she has not publicly opposed the central bank's recent moves, even as she faces pressure to bring inflation under control. The latest increase is the second since she took office, following a December hike to around 0.75 percent. For now, the BOJ appears to have room to maneuver. The US and UK both maintain rates above 3 percent, and both are expected to hold steady when they meet this week. Japan's gradual ascent from near-zero rates is a long journey, but it signals a country finally stepping out of the shadow of a three-decade crisis.

After twenty years of deflation, Japan is now in an inflationary upcycle. Emergency crisis management monetary policy is no longer needed and the BOJ wants to get back to normal monetary policy.— Jesper Koll, Japan economist
The Hearth Conversation Another angle on the story
Why does Japan's rate hike matter when the overall inflation rate is still below target?
Because wholesale prices are moving fast—6 percent year-over-year—and the central bank is signaling it believes inflation is the bigger risk now than economic weakness. They're trying to get ahead of it.
What changed? Japan kept rates near zero for twenty years without much complaint.
The world changed. Energy prices spiked globally, and Japan can't insulate itself. When oil gets expensive, it hits a country that imports most of its fuel. That broke the deflation spell.
Is the prime minister okay with this?
She hasn't fought it publicly, even though she's traditionally opposed to rate hikes. She's under pressure to control inflation, and the central bank has enough credibility that she's letting them move.
What's the real risk here?
Higher borrowing costs. The government carries enormous debt. Businesses will pay more to borrow. The central bank is betting that controlling inflation is worth that pain.
And the yen—why does that matter?
A weaker yen hurts Japan's purchasing power abroad and makes imports more expensive. Higher rates attract foreign investors to hold yen, which strengthens it. That's a side benefit the bank welcomes.
