# Japanese Bond Yields Surge to Multi-Decade Highs; BOJ Quantitative Tightening May End Early

Japanese government bond yields have recently climbed to their highest levels in decades, intensifying turmoil in the bond market and forcing the Bank of Japan (BOJ) to reassess its quantitative tightening path.

Citing two sources familiar with the matter, Reuters reported that **the BOJ will hold a policy meeting on June 15–16, where it will evaluate the current bond reduction plan and formulate a new scheme for fiscal year 2027.** The report quoted insiders stating that against the backdrop of ongoing Middle East tensions disrupting the bond market, pausing balance sheet reduction has become an increasingly favored option. "The market remains volatile, and there is no need to rush forward."

The yield on 10-year Japanese Government Bonds (JGBs) touched 2.8% last week, hitting a 30-year high and nearing the 3% warning threshold set by the Ministry of Finance when drafting the fiscal 2026 budget. Once yields breach this threshold, debt servicing costs will rise significantly, further squeezing fiscal space and directly constraining Prime Minister Sanae Takaichi's policy agenda of tax cuts and expanded spending.

These discussions come as the BOJ faces intertwined pressures—bond market turbulence, rising political pressure, and the difficult trade-off of whether to proceed with rate hikes in June. Market participants and former central bank officials generally view a pause in balance sheet reduction as reasonable, but this has also sparked external doubts about whether the BOJ can stick to its monetary normalization path.

## Yield Surge Triggers Fiscal Alarm

Persistent concerns over Japan's fiscal health and rising inflationary pressures have jointly driven the rapid climb in government bond yields. The 10-year JGB yield touched a 30-year high of 2.8% last week, just a step away from the 3% reference line set by the Ministry of Finance in the fiscal 2026 budget.

Nobuyasu Atago, a former BOJ official, stated, "We are seeing yields rise quite rapidly, making it difficult for investors to buy bonds, and the Ministry of Finance may also be starting to feel concerned." He added, "Given the political resistance, I see no reason for the BOJ to continue pushing ahead with balance sheet reduction in the next fiscal year."

Insiders also bluntly stated, "The last thing the authorities want to see is a rise in government bond yields." **If yields break through 3%, the Japanese government's debt servicing costs will expand further, and the already constrained fiscal space will become even tighter.**

## Balance Sheet Reduction Plan Faces Pressure to Pause

The BOJ launched its quantitative tightening plan in 2024 as a key component of Governor Kazuo Ueda's effort to unwind more than a decade of ultra-loose stimulus policies. Under this plan, the central bank is gradually reducing the scale of its government bond purchases, currently cutting monthly purchase volumes by JPY 20 billion per quarter. The BOJ currently holds approximately JPY 500 trillion in JGBs.

According to two sources familiar with the discussions, the BOJ has not yet reached a consensus on the final plan internally, **but pausing balance sheet reduction has gradually become the preferred option.** Reuters, known in the market for conveying signals from within the BOJ, is widely regarded as having provided a highly credible policy trial balloon with this report.

A central bank survey conducted by the BOJ earlier this month also showed that some investors have explicitly called for a pause in the bond reduction plan, highlighting the practical challenges the central bank faces in compressing its massive government bond holdings. Notably, even if the balance sheet reduction plan is paused, the BOJ's balance sheet has already shrunk by about 20% from its peak at the end of 2023 as existing JGBs naturally mature and roll off, a process that will continue.

## Political Pressure Strengthens Policy Resistance

Political factors cannot be ignored either. After taking office, Sanae Takaichi publicly promised to implement tax cuts and expand fiscal spending by issuing more government bonds, placing greater resistance on the BOJ's balance sheet reduction plan. This policy stance has raised investor concerns about fiscal sustainability in the world's most heavily indebted economy and has become one of the important drivers pushing yields higher.

Akira Otani, a former BOJ executive now at Goldman Sachs Japan, stated, "When inflation risks from the Middle East conflict and the government's aggressive fiscal policy simultaneously exert upward pressure on government bond yields, continuing to push ahead with balance sheet reduction could trigger political friction by driving yields higher."

Insiders also admitted that political considerations are an unavoidable background influencing the BOJ's decisions, and the rapid rise in yields has made the operational space for related policies increasingly narrow.

## The Policy Mix Game of Rate Hikes and Balance Sheet Reduction

In addition to pausing balance sheet reduction, **the possibility of the BOJ raising short-term interest rates from 0.75% to 1% at its June meeting is also seen by the market as a high-probability event.** Mari Iwashita, head of interest rate strategy at Nomura Holdings, Inc., believes that "combining a pause in balance sheet reduction with a rate hike is a superior policy mix"—the former helps alleviate upward pressure on yields, while the latter can ease external concerns that the BOJ is lagging behind in addressing inflation risks.

She also predicted that the BOJ would pause its balance sheet reduction plan in fiscal year 2027, pointing out: "Given such instability in the bond market, it is only logical for the BOJ to adopt a prudent stance to avoid causing unnecessary market turmoil."

The BOJ has previously consistently emphasized that its balance sheet reduction plan and monetary policy stance are independent of each other and not directly linked. However, if the central bank pauses balance sheet reduction while proceeding with rate hikes, this distinction will become more subtle, and the difficulty for the market to interpret the consistency of its policy framework will increase accordingly.

Japan's situation is not an isolated case. Years of large-scale asset purchases have caused the balance sheets of major central banks to expand sharply, and reducing holdings is now encountering widespread resistance. In the United States, analysts are skeptical about whether new Federal Reserve Chair Kevin Warsh can advance his proposal to compress the balance sheet, as the market appeal of U.S. Treasury bonds has declined.

The BOJ's next clear signal will arrive next week—when the central bank releases the minutes of its meetings with bond market participants held on May 21–22, the market will look for the latest clues regarding adjustments to the balance sheet reduction path.
