The bond market is bleeding. Institutional investors are dumping paper. The safety of the Japanese Government Bond (JGB) has evaporated. Today, February 7, the Tokyo exit polls have confirmed what the Nikkei has been whispering for weeks. Sanae Takaichi is positioned for a decisive victory. This is not merely a change in leadership. It is a fundamental repricing of Japanese risk.
The era of the ‘Japanese Discount’ is over. For decades, Japan exported deflation and cheap capital to the rest of the world. That pipeline is closing. Takaichi’s platform, built on a precarious balance of aggressive defense spending and fiscal sustainability, has sent a shockwave through the fixed-income markets. Traders are no longer asking if rates will rise. They are asking how fast the Bank of Japan will be forced to chase the market.
The Mandate for Normalization
The polls are unequivocal. The Liberal Democratic Party has secured a mandate that allows Takaichi to move past the cautious incrementalism of her predecessors. This political stability is a double-edged sword for the markets. On one hand, it ends the paralysis of leadership. On the other, it accelerates the timeline for ‘Normalcy’—a word that, in the Japanese context, means the end of subsidized borrowing costs.
Structural changes are the primary engine of this shift. Japan is no longer the stagnant pond of the 2010s. Wage growth has finally decoupled from the zero-bound. Labor shortages in the semiconductor and green energy sectors have forced a competitive bidding war for talent. Per the latest Reuters market analysis, nominal wages in the manufacturing sector have surged, creating a feedback loop that the Bank of Japan can no longer ignore. This is the ‘normal economy’ that ING Economics highlighted in their latest briefing.
The Arithmetic of Debt Sustainability
Takaichi faces a mathematical nightmare. She has promised significant increases in fiscal spending to bolster domestic technology and military deterrence. Yet, Japan’s debt-to-GDP ratio remains a towering monument to fiscal excess. The market is skeptical. If the government spends more while interest rates rise, the cost of servicing that debt could consume the national budget.
The ‘Takaichi Pivot’ requires a delicate hand. She must convince the markets that growth will outpace the rising cost of capital. This is a high-stakes gamble. If the 10-year JGB yield climbs too quickly, it risks a systemic shock to domestic banks that are still gorged on low-yield sovereign debt. The following table illustrates the shifting baseline of the Japanese macro environment over the last twelve months.
Comparative Economic Metrics
| Economic Indicator | February 2025 Actual | February 2026 Forecast | Variance |
|---|---|---|---|
| JGB 10-Year Yield | 0.88% | 1.48% | +60 bps |
| Core CPI (YoY) | 2.1% | 2.9% | +80 bps |
| USD/JPY Exchange Rate | 149.50 | 138.20 | -7.5% |
| Nikkei 225 Index | 38,200 | 42,150 | +10.3% |
The JGB Yield Curve Reaches for the Sky
The technical reason for the current market exodus lies in the widening spread between nominal yields and inflation expectations. As Takaichi prepares to take the podium, the market is pricing in a regime shift where the Bank of Japan no longer acts as the buyer of last resort. The yield curve is steepening. This is a sign that investors are demanding a higher term premium for the uncertainty of the next four years.
The ‘carry trade’—the practice of borrowing yen at near-zero rates to invest in higher-yielding assets abroad—is in a state of chaotic unwinding. As JGB yields rise, the incentive to keep capital at home increases. This repatriates trillions of yen, strengthening the currency but starving global markets of liquidity. We are seeing the first signs of this in the volatility of US Treasury spreads and European sovereign debt.

Global Contagion and the Yen Carry Trade
The world is not prepared for a hawkish Japan. For years, the Bloomberg bond indices have relied on Japanese institutional buying to anchor global rates. If Takaichi’s victory leads to a sustained rise in domestic yields, that anchor is gone. Japanese life insurers and pension funds, the largest holders of foreign debt, are already signaling a preference for domestic paper.
This is the structural change ING Economics referenced. It is a path toward a normal economy, but the transition is violent. The volatility in the currency markets reflects a tug-of-war between Takaichi’s spending needs and the Bank of Japan’s need to maintain price stability. If Takaichi spends too much, the yen could weaken despite higher rates, creating a cost-push inflation spiral that Japan has not seen since the 1970s.
The next critical data point arrives on February 25. That is when the Bank of Japan will hold its first post-election policy meeting. If the central bank signals an accelerated quantitative tightening (QT) program to match Takaichi’s fiscal expansion, the 10-year JGB yield will likely breach the 1.65 percent resistance level. That is the figure to watch. Above 1.65 percent, the global carry trade does not just unwind. It collapses.
