High political and market tension is building ahead of the Bank of Japan’s December 19 policy meeting, where the central bank is widely expected to raise its key interest rate by 25 basis points to 0.75%, according to analysts at Yardeni Research.
The decision places BOJ Governor Kazuo Ueda at the center of a rare confrontation with Japan’s political leadership as slowing growth, rising inflation and surging government bond yields collide.
The expected rate increase comes as Japan’s government bond market faces heightened pressure. Ten-year Japanese government bond yields have climbed to their highest levels since 2007, driven by Bond Vigilantes arguing that inflation, hovering around 3% year over year and above the BOJ’s 2% target, requires additional tightening.
The brokerage adds that the yen’s slide toward ¥160 to the dollar has further strengthened the case for normalization after a quarter-century of zero rates and quantitative easing across 14 governments.
Prime Minister Sanae Takaichi, who leads an administration pushing for stronger consumption through wage gains, is resisting tighter monetary policy.
The analysts added that Japan’s economy contracted 2.3% year over year in the third quarter and real wages fell 1.4% in September, marking the ninth straight monthly decline.
Officials aligned with the prime minister argue that raising rates now risks deepening a downturn as the country struggles to avoid recession.
Takaichi also faces scrutiny over Japan’s heavy debt load. The government’s debt-to-GDP ratio stood above 200% at the end of the third quarter, with some estimates placing it closer to 260%. Her latest fiscal package totals 18.3 trillion yen ($137 billion).

Yardeni Research notes that the measures have intensified bond-market unease, forcing the prime minister last week to assure lawmakers that Japan faces no risk of a “Truss shock,” referring to Britain’s 2022 market turmoil.
Ueda, who has spent the past two years reversing decades of ultra-easy policy, appears intent on securing a second rate hike this year.
His early steps included ending negative interest rates and yield-curve control in 2023 and beginning quantitative tightening by cutting JGB purchases by 400 billion yen per quarter before slowing to 200 billion yen as growth weakened. Markets have largely priced in the December move, with 10-year yields approaching 2%.
The brokerage warns that a deeper clash between the BOJ and the government could send JGB yields and the yen sharply higher, potentially disrupting the yen-carry trade and rippling through global markets.
The tension reflects longstanding structural challenges: Japan’s reliance on monetary stimulus since 2001 left the BOJ’s balance sheet larger than the country’s $4.2 trillion GDP by 2018. Today, the benchmark rate remains at the same level as in 2007, the last time yields were this elevated.
