Japanese Prime Minister Sanae Takaichi is preparing a supplementary budget of about 3 trillion yen ($19 billion) to alleviate the financial strain on households due to rising living costs. This move has sparked skepticism regarding the government's ability to manage debt, particularly as the 10-year Japanese sovereign bond yield surged to 2.809%, the highest level since 1996. Takaichi's budget marks a shift from her previous stance against additional spending, raising concerns among investors about the implications of increased debt issuance. Analysts like Jesper Koll warn that the bond market is reacting to the uncertainty surrounding Japan's fiscal policies, particularly as inflation and subsidy costs rise. While some analysts believe the supplementary budget is a targeted approach to support households rather than a broad stimulus, the bond market remains cautious. Recent economic data indicates a 2.1% annualized growth rate in the first quarter, with exports increasing by 14.8% in April, driven by strong demand in semiconductors and AI. However, the yen remains weak, trading near 160 against the dollar, which could trigger intervention.
