Nomura: Japan's Bond Market Flashing Fiscal Risk Warning Signals

Nomura's chief economist Rob Subbaraman warns that Japan's government bond market is "sending warning signals" — rising borrowing costs threaten PM Sanae Takaichi's fiscal expansion, while cost-driven inflation traps the Bank of Japan in a policy dilemma.
What is the bond market warning?
Nomura chief economist Rob Subbaraman says Japan's government bond market is "sending warning signals" on fiscal risk.
The backdrop: PM Sanae Takaichi is pushing fiscal stimulus aimed at boosting nominal growth, requiring heavy government borrowing.
This means → the market is demanding higher interest rates as compensation for rising risk, making the fiscal expansion itself more expensive.
Why are rising borrowing costs dangerous?
Subbaraman warns that rising borrowing costs could directly undermine Takaichi's stimulus strategy.
In plain terms = the government is borrowing to spend, but the interest bill keeps climbing — at some point the stimulus chokes on its own cost.
Japan's public debt is already the highest among developed nations; even a small rate increase sharply inflates interest payments.
Why is the Bank of Japan stuck?
Japan's current inflation is mainly cost-driven — pushed up by raw-material and import prices, not by strong consumer demand.
This means → the BOJ faces a dilemma: tighten too fast and the recovery stalls; stay loose and inflation expectations keep rising, adding more pressure to the bond market.
This reflects a deeper clash — fiscal policy is hitting the accelerator while monetary policy has no room to brake, and the two are squeezing each other.
