Japan’s bond market chaos erupts after PM’s snap election and tax-cut pledge

Japan’s government bond market has been thrown into turmoil after Prime Minister Sanae Takaichi announced a snap election and promised expensive tax cuts on food. The move triggered a sharp sell-off, sending bond yields to record levels and driving up global borrowing costs.

The sell-off began when Takaichi dissolved the Lower House, setting a general election for February 8, 2026. Investors reacted by dumping Japanese government bonds, causing their value to collapse. As prices fell, yields surged—with the 40-year bond yield climbing above 4% for the first time since its launch in 2007.

The spike in Japanese yields rippled across global markets. The UK’s ten-year gilt yield neared 4.5%, adding pressure on governments worldwide. Finance Minister Satsuki Katayama later urged calm, but the damage to borrowing costs had already spread.

The bond market chaos follows Takaichi’s election gamble and tax-cut promises. With yields at historic highs, Japan’s global entry costs have risen sharply. The fallout has also pushed up interest rates for other nations, leaving governments facing steeper debt expenses.
