Published on: January 20, 2026

Buyers flee Japanese debt as Takaichi hits the ground spending

TOKYO — The Japanese government bond (JGB) market is facing a “canary in the coal mine” moment. Investors are liquidating holdings at a record pace following Prime Minister Sanae Takaichi’s confirmation of a snap election and a series of unfunded fiscal promises that have drawn comparisons to the 2022 UK “mini-budget” crisis.

1. The Numbers: A Historic Rout

On Tuesday, January 20, the sell-off reached a fever pitch. Yields across the curve hit multi-decade highs as the “wall of cash” usually supporting Japanese debt began to crumble.

10-Year Benchmark: Surged to 2.37%, the highest level since the Asian Financial Crisis era of 1999.
40-Year JGB: Rocketed past 4.2%, a record high since the maturity’s debut in 2007.
The 20-Year Spike: Yields jumped 19.5 basis points in a single day—the steepest one-day move in years—after a disastrous government auction saw the lowest demand (bid-to-cover ratio) since December.

2. “Sanaenomics” and the Consumption Tax Bombshell

The catalyst for the exodus is Prime Minister Takaichi’s campaign platform for the February 8, 2026, general election. To secure a mandate, she has pledged a two-year suspension of the 8% sales tax on food.

The Fiscal Gap: Economists estimate this tax holiday will create a ¥5 trillion ($31.6 billion) hole in annual revenue. With Japan’s debt-to-GDP ratio already hovering near 230%, markets are panicked by the lack of a clear funding plan, fearing a massive surge in new bond issuance.

3. A Perfect Storm: Politics Meets the BoJ

The bond rout is being exacerbated by a “squeeze” from two sides:

Fiscal Expansion: Takaichi’s “responsible stimulus” is seen as inherently inflationary, requiring more borrowing.
Monetary Tightening: The Bank of Japan (BoJ) is expected to hold rates at 0.75% this Friday, but Governor Kazuo Ueda is under immense pressure. With the Yen hovering near 158.50 per dollar, the BoJ may be forced into a “hawkish” surprise in June to prevent a total currency collapse.

4. Global Contagion Risks

This is no longer just a Japanese problem. As the world’s largest creditor nation, Japan’s rising yields are “exporting” volatility. On Tuesday, US Treasuries and European Bunds also saw yields climb as the JGB sell-off forced global portfolios to rebalance, dragging the world’s bond markets lower in sympathy.
