Japanese government bond markets experienced a sharp movement on Thursday, July 3, with yields on long-term bonds briefly climbing to 2.81 percent — their highest level in thirty years. The spike prompted one analyst to coin the term “honebuto shock,” a reference to the government’s Basic Policy on Economic and Fiscal Management and Reform (the honebuto) and the Bank of Japan’s sluggish response to tightening financial conditions.
The term draws on the Japanese word for “bone” or “framework,” reflecting the core policy document that outlines the Takaichi government’s fiscal strategy. Markets are increasingly concerned that the government’s pending honebuto will signal larger deficits, especially as the Bank of Japan (BOJ) has been slow to adjust its monetary stance amid rising inflation and a weakening yen.
Government on the Defensive
The bond market reaction has put the Takaichi administration on the back foot. Chief Cabinet Secretary Minoru Kihara stated that the government is “closely watching market trends” and pledged to “take every possible measure to ensure sound economic and fiscal management.” Finance Minister Satsuki Katayama downplayed concerns that the draft honebuto might threaten the BOJ’s independence, suggesting that the government would manage bond issuance with an eye toward maintaining market confidence.
Economic Revitalization Minister Minoru Kiuchi argued that the market movement was not solely a reaction to the government’s fiscal policies, hinting at broader global factors. However, Centrist Reform Alliance (CRA) leader Junya Ogawa used his July 3 press conference to criticize the government for what he called irresponsible policies, characterizing the market reaction as a clear warning signal.
Political friction is also emerging within the ruling Liberal Democratic Party (LDP). Yuko Obuchi resigned from the LDP tax commission to protest the government’s consumption tax cut plan, a move that underscores growing discontent with Prime Minister Takaichi’s approach. The combination of market jitters and internal party dissent suggests that the political dynamics around fiscal policy are only beginning to intensify.
Consumption Tax Talks Stall
The political stalemate has extended to the National Conference on Social Security, which has been working on an interim report to inform the government’s consumption tax plan. The working committee drafting the report has not met since June 26, preventing finalization before the end of the month and pushing the deadline into July or later.
The Takaichi government had hoped to include a consumption tax cut in the honebuto, but the delay may not deter the administration from proceeding unilaterally. However, opposition parties are increasingly reluctant to endorse what they view as a purely partisan measure. A report in Diamond described how the prime minister’s impatience with slower, thorough deliberations led to a near breakdown in the process.
The broader context includes ongoing debates about Japan’s fiscal sustainability and the BOJ’s monetary policy. As the yen continues to weaken, the central bank faces pressure to normalize rates, but doing so could increase the government’s debt-servicing costs. The honebuto shock term reflects a growing recognition that Japan’s fiscal and monetary policies are on a collision course.

Meanwhile, the BOJ’s decades-old monetary experiment continues to pose risks to the yen, as discussed in Bank of Japan's Decades-Old Monetary Experiment Now Threatens the Yen.
As the Takaichi government navigates these challenges, the interplay between fiscal policy, market confidence, and political cohesion will be critical. The honebuto shock may prove to be more than a fleeting term if bond yields continue to rise and political opposition hardens.
