Bill Campbell, head of the Global Sovereign & Emerging Markets team at DoubleLine, describes the current volatility as the 'Honebuto shock.' The term references the turbulence following Tokyo’s latest fiscal policy statement, which mandates over 370 trillion yen in public-private investment through 2040. Markets are reacting sharply to the government’s explicit call for monetary policy to align with this growth agenda, a move interpreted as an attempt to subordinate the central bank to political objectives.

Campbell argues that this strategy risks triggering a buyers' strike, as fiscal credibility remains fragile in a global inflationary environment. He warns that the Takaichi administration should not expect the JGB market to show more patience than the UK gilts market did during the 2022 crisis. For international investors, the signal is clear: demand for fiscal discipline is no longer optional, even for G-7 nations.
