Japan Bond Yields Hit 30-Year High, Sparking ‘Honebuto Shock’

Japanese government bonds briefly climbed to 2.81% on Thursday, July 3—their highest level in 30 years. The sharp rise has led analysts to coin a new term: the “honebuto shock.” The name refers to the government’s Basic Policy on Economic and Fiscal Management and Reform, known in Japanese as the *honebuto*. Investors are reacting to the possibility of larger deficits under the Takaichi administration’s upcoming policy plan. At the same time, the Bank of Japan has been slow to adjust its monetary policy. This combination—rising debt fears and hesitant central bank action—has unsettled bond markets. The yield jump signals growing concern about Japan’s fiscal direction. Market watchers will now focus on the final version of the *honebuto* policy, expected in the coming weeks.
