TOKYO :The Bank of Japan's retreat from a decade-long radical stimulus is pressuring the government to rethink the way it funds its big spending packages with additional debt, a challenge made more daunting by political demands for permanent tax breaks. Prime Minister Shigeru Ishiba's administration plans to spend 13.9 trillion yen ($92 billion) for a package of steps to cushion the blow from rising living costs, which will be funded by this year's supplementary budget to be finalised on Friday.
