Japan Eyes Reduction in Inflation-Linked Bond Buybacks Amid Surging Investor Demand

Japan's finance ministry is reportedly considering scaling back its buybacks of inflation-linked government bonds as investor appetite for these securities continues to grow on the back of rising inflation expectations. Two sources familiar with the discussions revealed the development on Monday, though both requested anonymity given the sensitivity of the matter.

Market-based inflation expectations, tracked through the break-even inflation rate, crossed 1.9% for the first time in late January — a threshold that has made inflation-protected securities increasingly attractive to institutional and retail investors alike. These bonds are structured so that both principal and interest payments adjust in accordance with consumer price growth, offering a natural hedge against inflation risk.

Under the proposed plan, the ministry would reduce its buyback volumes to 15 billion yen each in April and June — roughly half the 20 billion yen purchased monthly across January, February, and March. Officials are expected to consult market participants on the proposal in the coming weeks before reaching a final decision.

Notably, the issuance volume for inflation-linked bonds is expected to remain steady at 250 billion yen for May, signaling that the government aims to support continued market development even as it trims repurchase activity.

Japan originally launched inflation-linked bonds in 2004, but suspended issuance in 2008 as deflationary pressures threatened principal losses. The program was revived in 2013 under former Prime Minister Shinzo Abe's aggressive anti-deflation agenda. Since then, authorities have worked to strengthen the market through guaranteed principal protections and consistent buyback programs.

Inflation pressures in Japan had already been building before the Middle East conflict, which has since provided additional upward momentum to global prices. Despite a positive shift in the supply-demand gap for the first time in two quarters, economists caution that a sustained demand recovery still requires more time to materialize.
