日本增发巨额国债刺激经济，债汇遭抛售或触发全球债市风暴

Core Viewpoint - The Japanese government is planning to finance a new round of economic stimulus through a significant increase in government bond issuance, amounting to approximately 11.7 trillion yen (about 529.9 billion RMB) to cover the spending gap from the recently announced economic measures [1][2]. Group 1: Economic Stimulus Plan - The 2025 supplementary budget is expected to have general account expenditures of about 18.3 trillion yen, with 17.7 trillion yen allocated for the implementation of the economic measures, marking a substantial 27% increase from the previous year's 13.9 trillion yen [2]. - The total scale of the comprehensive economic measures is approximately 21.3 trillion yen, indicating a significant commitment to economic stimulus despite the associated debt concerns [1][2]. Group 2: Debt Issuance and Market Reaction - The planned bond issuance significantly exceeds the 6.7 trillion yen in bonds issued by the previous administration, reflecting Japan's heavy reliance on debt financing [2]. - The Japanese yen and long-term government bonds have been under pressure, with the yen trading around 156 against the dollar and long-term bond yields rising, indicating market concerns over Japan's fiscal health [3][4]. Group 3: Fiscal Concerns and Future Outlook - Japan's debt-to-GDP ratio has surpassed 260%, raising questions about the government's ability to balance economic stimulus with fiscal responsibility [5]. - Analysts express concerns that continued reliance on debt issuance could exacerbate fiscal deterioration, especially given the pressures from an aging population and the sustainability of tax revenue growth [5][6]. - The potential for rising interest rates, coupled with high leverage, could increase interest expenditure as a proportion of fiscal spending, further straining the budget [5][6]. Group 4: Global Implications - The ongoing sell-off of Japanese assets may have broader implications for global markets, particularly if investors liquidate overseas assets to cover yen-denominated loans, potentially impacting U.S. Treasuries and equities [7]. - The risk of a liquidity crunch in global markets could arise if yen carry trades are unwound, leading to capital outflows from emerging markets [7].
