After twenty years of deflation, Japan is now in an inflationary upcycle
After three decades of economic caution born from collapse and deflation, Japan's central bank has raised its policy rate to 1 percent — the highest since 1995 — signaling that the long emergency may finally be over. Driven by surging global energy prices tied to Middle East tensions, the Bank of Japan is attempting something rare in its recent history: a return to normalcy. The decision carries weight beyond Japan's borders, as it may reflect a broader global reckoning with the costs of prolonged monetary accommodation.
- Wholesale prices in Japan climbed over 6 percent year-on-year in May, the fastest pace in three years, forcing the central bank's hand despite overall inflation still sitting below its 2 percent target.
- The rate hike — from 0.75 to 1 percent — is the latest step in a tightening cycle that began in March 2024, ending two decades of near-zero rates that once served as economic life support after Japan's asset collapse in the 1990s.
- Higher borrowing costs now threaten to squeeze government spending and business investment, putting the Bank of Japan in direct tension with a prime minister who favors fiscal expansion.
- The yen's persistent weakness adds urgency: a higher rate makes yen-denominated assets more attractive, offering a potential stabilizing effect on a currency many consider undervalued.
- With the BOJ governor hospitalized and absent from the meeting, the decision still passed — a sign that the institution's direction is now larger than any single figure's presence.
On Tuesday, the Bank of Japan raised its policy rate to 1 percent, the highest level since 1995, marking a significant departure from the emergency monetary posture the country has maintained since the economic collapse of the 1990s. The catalyst was a sharp rise in global energy prices, amplified by Middle East tensions, which pushed Japan's wholesale prices up more than 6 percent compared to a year earlier — the fastest increase in three years.
This is not an abrupt reversal but the continuation of a careful unwinding. The BOJ began raising rates in March 2024, its first increase in seventeen years, after two decades of near-zero rates designed to fight deflation and stagnation. Economist Jesper Koll has described Japan as now entering an inflationary upcycle for the first time in a generation — a moment when emergency measures are no longer warranted.
The path forward is not without tension. Japan's overall inflation remains at 1.4 percent, still below the bank's 2 percent target, and higher rates risk slowing growth and increasing the cost of government borrowing. Prime Minister Sanae Takaichi, a proponent of expansionary spending, has historically opposed rate hikes, though she has not publicly challenged the bank's recent moves. Governor Kazuo Ueda was absent from the meeting due to hospitalization, yet the decision proceeded — reflecting an institutional resolve that transcends individual leadership.
Beyond Japan, the move may carry a wider signal. With the yen weakened and major economies from the US to Australia navigating their own rate decisions, analysts like Ulrike Schaede suggest Japan's shift could be part of a slow global realignment — a collective reckoning with how long accommodative monetary policy can be sustained before the world must return to something closer to normal.
On Tuesday, Japan's central bank made a decision that marks the end of an era. The Bank of Japan raised its policy rate to 1 percent, the highest level in thirty-one years, stepping further away from the emergency monetary policies that have defined the country's economic life since the 1990s.
The move came as global energy prices surged, particularly following tensions in the Middle East, pushing up the cost of living across economies dependent on oil and gas imports. Japan, which relies heavily on Middle Eastern energy, felt the pressure acutely. Wholesale prices climbed more than 6 percent in May compared to a year earlier—the fastest pace in three years. The central bank, which had held its rate at 0.75 percent, decided the moment had come to tighten further.
This is not a sudden shift. The Bank of Japan began raising rates in March 2024, the first increase in seventeen years, after two decades of near-zero rates designed to combat deflation and economic stagnation. Asset prices had collapsed in the 1990s, and for twenty years afterward, prices fell and growth remained sluggish. The central bank kept rates near zero as a form of economic life support. Now, according to economist Jesper Koll, Japan has entered "an inflationary upcycle" for the first time in a generation. The emergency measures, he said, are no longer necessary. The bank wants to return to normal monetary policy.
Yet the situation remains delicate. Japan's overall inflation rate sits at 1.4 percent, still below the central bank's 2 percent target. The bank acknowledged that government measures—including relief for households facing high fuel costs—have reduced the risk of the economy deteriorating sharply from energy shocks. But it also warned that medium- and long-term inflation expectations are rising, and there is a risk of underlying inflation climbing above its target.
The central bank faces a classic dilemma: raising rates can cool inflation, but higher borrowing costs make loans more expensive for businesses and the government itself. Prime Minister Sanae Takaichi, who favors increased government spending, has previously opposed rate hikes, though she has not publicly criticized the central bank's recent moves since taking office last year. The bank's governor, Kazuo Ueda, missed this week's meeting due to hospitalization for treatment of an infected liver cyst, but he has signaled in recent months that if upside risks to prices outweigh downside risks to economic activity, raising rates becomes necessary.
There is another dimension to the decision: the yen. Japan's currency has weakened against the dollar and euro, and a higher interest rate can help stabilize it by making yen-denominated assets more attractive. According to Ulrike Schaede, a business professor at the University of California San Diego, there has been a sense that the yen is undervalued and that raising rates will not harm the economy.
Even at 1 percent, Japan's rate remains low compared to other major economies. The United States and United Kingdom both hold rates above 3 percent, though both are expected to hold steady when they meet this week. Australia's central bank kept its rate at 4.35 percent on Tuesday but signaled it may raise again if inflation pressures persist. What Japan is doing, Schaede suggested, could signal "a slow global realignment"—a broader shift in how the world's major economies manage inflation and currency stability after years of accommodative policy.

Why does Japan raising rates to 1 percent matter to anyone outside Japan?
Because Japan has been the world's longest experiment in near-zero rates. If that model is breaking, it changes how central banks everywhere think about managing deflation and stagnation.
But 1 percent is still very low compared to the US or UK.
True. But the direction matters more than the absolute number. Japan spent twenty years at near-zero. Moving to 1 percent is a signal that the old crisis is over. That's a psychological shift as much as an economic one.
What's the real constraint on raising rates faster?
The government's debt burden and the fear of slowing growth. Higher rates make it more expensive for the government to borrow, and they make businesses less likely to invest. Japan's economy is fragile enough that the central bank has to move carefully.
So why raise rates at all right now?
Energy prices are pushing inflation up faster than expected. The central bank has to show it's serious about controlling prices, or inflation expectations could spiral. It's a preemptive move.
What happens if they raise too fast?
They could trigger a recession. What happens if they don't raise enough? Inflation becomes embedded in wage expectations and becomes much harder to control later. They're trying to thread a needle.
Is the yen situation driving this more than inflation?
It's both. The weak yen makes imports more expensive, which feeds inflation. Higher rates help the yen. So the central bank is solving two problems at once, which is why the move feels inevitable even though it's risky.
