Japan's bond market is in freefall, unleashing a $7 trillion risk for global financial systems. The sell-off accelerates as the country hurtles toward a snap election called by Prime Minister Takaichi. Investors fear more unpredictable and violent price swings ahead, threatening stability in a key pillar of the global economy.

The turmoil stems from rising yields and a weakening yen, forcing a reckoning for leveraged global investors. Japan's government debt, the largest in the world relative to its economy, has long been a safe haven. This shift could trigger a cascade of losses across portfolios that depend on stable Japanese rates and currency hedges.

All eyes now turn to the Bank of Japan's next move and the election's outcome. Takaichi's policy platform remains a key variable for markets. The potential for a sustained crisis could force central banks worldwide to recalibrate their strategies, making Japanese government bonds the most watched asset class for the foreseeable future.
