月度债务可持续性仪表板：谁将最受伤？

关键论点

• 债务与GDP之比是一个过于简单的衡量指标；基本赤字、利率和债务持有结构对可持续性更为关键。
• 美国、英国和法国需要采取紧缩措施以稳定或降低政府债务比率。
• 在现行政策下，美国财政状况恶化，OBBBA法案到2034年将增加2.8万亿美元国债。
• 德国和法国需要约占GDP 2%的财政整顿以维持债务比率稳定。
• 英国财政前景好于普遍预期，由于税收起征点冻结，正在实施财政整合。
• 欧元区分化可能再次成为主题，分化加剧的债券市场将考验欧洲央行重启资产购买的意愿。

对应原文证据

1. At current levels, interest rates do not pose a solvency issue for governments. For most countries, the real 10y interest rate is still below real GDP growth. However, many countries (US, UK and France) do need austerity measures to at least stabilise government debt ratios. · medium-term
2. President Donald Trump’s One Big Beautiful Bill Act (OBBBA) did include over $1tr of healthcare spending cuts for the coming decade, but the permanent extension and expansion of tax cuts and more spending on other areas, including border security, led the Congressional Budget Office to conclude that OBBBA will in fact add $2.8tr to the national debt by 2034. · long-term
3. With France, Italy, Spain, Belgium and Greece, five out of 21 member states have debt-to-GDP ratios of above 100%. While the former periphery countries have built up fiscal cushions, even allowing for some slippage, France and Germany would currently need austerity measures worth some 2% of GDP to keep debt ratios stable. · medium-term
