Abstract:Japanese financial markets are witnessing a historic rout, with 40-year yields touching 4% following a failed bond auction and PM Sanae Takaichi's pledge to end fiscal austerity. The volatility puts immense pressure on the Bank of Japan to signal a rate hike as early as April to defend the Yen.

Japan is at the epicenter of a global bond market storm this Tuesday, suffering a brutal “double kill” in stocks and bonds. The catalyst was a collision of aggressive fiscal politics and a collapsing appetite for sovereign debt.
The sell-off in Japanese Government Bonds (JGBs) reached historic levels following a dismal 20-year auction. The bid-to-cover ratio dropped to 3.19, significantly below the 12-month average of 3.34, signaling a drought in demand.
Fueling the fire is Prime Minister Sanae Takaichi's surprise announcement of a snap election for February 8, alongside a pledge to dismantle “excessive fiscal tightening.” Her promise to cut consumption taxes and ramp up strategic spending has spooked investors, who fear a deterioration in fiscal discipline just as global rates rise.
The sharp rise in yields and the continued depreciation of the Yen (hitting fresh lows against the Dollar before a slight rebound) has intensified pressure on the Bank of Japan (BOJ).
While the central bank is expected to hold rates at 0.75% this Friday, Governor Kazuo Ueda faces a critical dilemma. With inflation risks rising due to the weak Yen and potential fiscal expansion, sources suggest the BOJ is internally debating an April rate hike. The market will scrutinize Friday's economic outlook report for any upward revision in inflation forecasts or signaling of a hawkish pivot to stem the bleeding in the bond market.
