*As the country hurtles towards the snap election called by Prime Minister Takaichi, more unpredictable and violent price swings are expected.*

Days after Japanese bonds crashed, sending tremors through global financial markets, traders were still stunned by the speed and breadth of it all. A quarter-point surge in yields “in a single session,” marveled Pramol Dhawan, a fund manager at Pacific Investment Management Co., “let that sink in.”
In the Japanese government bond market of old, it would take weeks — sometimes months — for yields to eke out, tick by tick, a move of that magnitude. For most of the 21st century, the JGB market was so steady — and interest rates were stuck at such rock-bottom levels — that Tokyo was viewed by investors around the world as a source of both cheap funding and of stability during times of global turmoil.
Last week’s selloff, accompanied by dramatic swings in the yen, made clear those days are over. Inflation, long dormant in Japan, has taken hold and, moreover, Prime Minister Sanae Takaichi is pushing fiscal stimulus plans that would swell a government debt pile that is already uncomfortably large. As a result, investors have been frantically sending bond yields up to levels once unthinkable — more than 4% on the longest-dated JGBs. That’s exerting upward pressure on interest rates from the US to Britain and Germany.
Traders are braced for more disorderly market swings as Japan hurtles toward a Feb. 8 snap election for which both Takaichi and her rivals have campaigned on looser budgets. An even bigger worry for global markets over the long term is that the new normal of higher Japanese yields will prompt domestic investors to bring much more of their money back home. Some $5 trillion of the country’s capital is deployed overseas, and that’s even before accounting for the yen that foreign funds have borrowed for their wagers in financial assets around the world.
