Japan is mulling a cut in its buybacks of inflation-linked government bonds as investor interest surges, according to sources familiar with the matter. The decision comes at a time when inflation expectations in the country are on the rise, making these bonds increasingly attractive.
In late January, market-based inflation expectations, tracked via the break-even inflation rate, climbed above 1.9% for the first time, highlighting the growing appetite for securities that protect against inflation. These bonds adjust both principal and interest payments according to changes in consumer prices, making them a safe haven for investors concerned about rising costs.
Sources say the Ministry of Finance is weighing a plan to scale back buyback amounts, targeting purchases of 15 billion yen (around $94 million) each in April and June. This would represent a significant reduction from recent months, where buybacks reached 20 billion yen in January, February, and March. Although the buyback volume may decrease, issuance of the bonds is expected to remain steady at 250 billion yen in May, with a final decision expected later this month.
Japan first introduced inflation-linked bonds in 2004 but halted issuance in 2008 due to deflation, which risked principal losses. The program resumed in 2013 under former Prime Minister Shinzo Abe, who aimed to pull the economy out of deflation. Since then, the government has sought to support the market through guaranteed principal and ongoing buybacks, encouraging investor confidence.
Economists note that while the supply-demand gap has turned positive for the first time in two quarters, a full recovery in demand is still some way off. External factors, including the recent Middle East conflict, have added to global price pressures, influencing Japan’s bond market strategy.
The finance ministry is expected to engage with market participants soon to discuss the proposed reduction. Observers say the move reflects a careful balance between managing investor demand and ensuring fiscal prudence amid rising inflation expectations.
As Japan navigates these changes, the market will closely watch both government actions and investor responses, since inflation-linked bonds remain a critical tool for protecting savings and stabilizing the economy in an era of rising global prices.
