A shocker in the world of sovereign debt.
S&P has cut the credit rating of Japan from AA to AA-.
The yen dove on the news.
VIA FT Alphaville, here’s part of the statement from S&P:
The downgrade reflects our appraisal that Japan’s government debt ratios–already among the highest for rated sovereigns–will continue to rise further than we envisaged before the global economic recession hit the country and will peak only in the mid-2020s. Specifically, we expect general government fiscal deficits to fall only modestly from an estimated 9.1% of GDP in fiscal 2010 (ending March 31, 2011) to 8.0% in fiscal 2013. In the medium term, we do not forecast the government achieving a primary balance before 2020 unless a significant fiscal consolidation program is implemented beforehand.
Japan’s debt dynamics are further depressed by persistent deflation. Falling prices have matched Japan’s growth in aggregate output since 1992, meaning the size of the economy is unchanged in nominal terms. In addition, Japan’s fast-ageing population challenges both its fiscal and economic outlooks. The nation’s total social security related expenses now make up 31% of the government’s fiscal 2011 budget, and this ratio will rise absent reforms beyond those enacted in 2004. An ageing and shrinking labour force contributes to our modest medium-term growth estimate of around 1%.
