Japan's policy rate has gone from negative to 0.75%, and long-term yields just hit 2.43%, a 27-year high. The country once known as "the land of zero interest rates" is now the only developed nation still raising them. Three years into Governor Kazuo Ueda's tenure, here's his report card, by the numbers.

Three Years of Ueda's BOJ: Four Rate Hikes Into "A World With Interest Rates"

When Kazuo Ueda took office as Bank of Japan governor in April 2023, he became the first academic economist to hold the position in the postwar era. He inherited the "unprecedented monetary easing", massive bond purchases and negative interest rates designed to stimulate the economy, that his predecessor Haruhiko Kuroda had maintained for a decade.

In three years, Ueda has delivered four rate hikes. He ended negative rates in March 2024 (Japan's first hike in 17 years), raised to 0.25% in July 2024, to 0.50% in January 2025, and to 0.75% in December 2025, the highest level in 30 years. Every decision was unanimous, reflecting a careful, communication-heavy approach.

On April 9, 2026, Ueda told parliament that real interest rates remain "clearly negative," meaning financial conditions are still accommodative. In other words, the BOJ sees itself as merely easing off the accelerator, not hitting the brakes.

Long-Term Yields at 2.43%: What a 27-Year High Means

On April 7, 2026, Japan's benchmark 10-year government bond yield surged to 2.43%, the highest since February 1999, roughly 27 years ago. The previous session had already set a record at 2.425%, marking consecutive days of new highs.

The 1999 episode was the "Trust Fund Bureau Shock," when the Ministry of Finance's investment arm stopped buying government bonds, triggering a spike. This time, the drivers are more complex.

First, Middle East tensions. The escalating geopolitical crisis around Iran has pushed oil prices sharply higher. Japan imports nearly all its energy, so rising crude directly feeds into inflation. Expectations of persistent price pressures led investors to sell bonds, pushing yields up.

Second, early BOJ rate hike expectations. The BOJ's new inflation indicators published in March showed underlying CPI (excluding subsidies and special factors) running at 2.2% year-on-year, with a broader measure at 2.7%. Markets increasingly expect a rate hike at the April 27-28 policy meeting.

Third, fiscal concerns under the Takaichi government. Prime Minister Sanae Takaichi, who took office in November 2025, has championed "responsible but active fiscal policy" and floated consumption tax cuts. The prospect of increased government borrowing has added a risk premium to Japanese bonds, widening the spread between policy rates and long-term yields, an unusual dynamic during a tightening cycle.

The April Rate Hike Debate and the Path to "Neutral"

The BOJ's April 27-28 policy meeting held rates at 0.75%, defying part of the market that had leaned toward a hike. At the March meeting, the board voted 8-1 to hold at 0.75%, with board member Hajime Takata dissenting in favor of a hike to 1.0%.

Takata described the current moment as "a true dawn" for Japanese monetary policy in a February speech, advocating for continued gradual hikes and warning that falling behind the curve would require larger adjustments later.

Some reports had put the market-implied probability of that April hike at around 70%. If executed, the policy rate would reach 1.0%, the lower bound of the BOJ's own neutral rate estimate range of 1.0-2.5%.

The IMF weighed in on April 3 with its Article IV consultation report, recommending the BOJ "continue gradual rate increases toward the neutral level." The IMF estimates Japan's neutral rate at approximately 1.5% and projects rates reaching that level by late 2026.

However, the oil shock from Middle East tensions complicates the calculus. Higher energy costs could drag on growth even as they fuel inflation, the classic stagflation dilemma that makes central banking exceptionally difficult.

The Only G7 Nation Still Hiking: Contrast With the Fed and ECB

What makes Ueda's BOJ unique is its position as the sole major central bank still in a tightening cycle.

The U.S. Federal Reserve began cutting rates in September 2024 and currently sits at 3.50-3.75%. President Trump's push to install a more dovish Fed chair adds further downward pressure on U.S. rates.

The European Central Bank had also been on a cutting path, but surging oil prices are now forcing a reassessment, with rate hike discussions emerging. The Bank of England faces a similar pivot.

This divergence directly impacts currency markets. While narrowing interest rate differentials between the U.S. and Japan should support the yen, it remains weak at around 159 per dollar. This reflects Japan's fiscal risk premium, driven by government debt exceeding 250% of GDP, and its structural vulnerability as a major energy importer.

Mortgages, Savings, and Business: How Rising Rates Hit Daily Life

The arrival of "a world with interest rates" is reshaping household and corporate finance across Japan.

For homeowners, fixed mortgage rates have been climbing in step with long-term yields. Variable rates also rose after major banks adjusted their prime lending rates following the December 2025 hike. Japan's "5-year rule" (payments stay flat for five years) and "125% rule" (increases capped at 125% of the previous amount) cushion the initial impact, but the interest portion of payments is steadily growing.

On the positive side, deposit rates are finally moving off near-zero for the first time in three decades. Yields on individual government bonds (for retail investors) have hit record highs, benefiting retirees and conservative savers.

For businesses, rising borrowing costs affect capital investment and working capital. Large corporations can absorb the impact with their massive retained earnings (approximately $3.7 trillion across Japanese firms), but small and medium enterprises face a survival challenge. The corporate bond issuance environment has also tightened.

Global Ripple Effects

Japan is the world's largest net creditor nation, and decades of ultra-low rates drove enormous capital outflows. The yen carry trade, borrowing cheaply in yen to invest in higher-yielding currencies, is estimated at roughly $270 billion by the Bank for International Settlements.

As BOJ rate hikes progress, an unwinding of these positions could send shockwaves through global markets. In August 2024, a BOJ rate hike and hawkish forward guidance contributed to a worldwide equity selloff, a warning of what could come.

The BOJ is also pursuing quantitative tightening (QT), gradually reducing monthly bond purchases toward approximately $13.5 billion by early 2027. The BOJ's share of outstanding government bonds is projected to fall from over 40% today to 21% by fiscal 2031, creating sustained upward pressure on long-term yields.

Ueda's Remaining Two Years: The Verdict Is Still Out

Ueda's term runs until April 2028. His track record of dismantling negative rates and executing a disciplined normalization has drawn praise, but the hardest chapters lie ahead.

The tension with Prime Minister Takaichi's government, the external shock from the Middle East crisis, and the question of where exactly neutral sits, all remain unresolved. Ueda, who as a BOJ board member in 2000 opposed a premature exit from zero rates that later backfired, knows better than anyone the cost of getting timing wrong.

Japan has finally entered "a world with interest rates." Some welcome higher deposit yields, while others worry about mortgage burdens. How are interest rates changing in your country, and how is it affecting your life? We'd love to hear your perspective.
