The spread differential between Japan sovereign CDS and UK sovereign CDS (both denominated in USD) is near its widest on record (Japan 55bps wider than UK). Furthermore, Japan's CDS trades notably wider (101bps in 5Y) than its bond's yields (which are the domestically held and subdued by local savings unlike the USD-denominated CDS market) while UK CDS trades 24bps inside its Gilts 5Y yield - quite a difference. Flows have surged into both the Japanese and British markets as AAA safe havens 'were' in demand (until the all-clear appears to have been signaled recently?). The critical point here is that these two nations have devastatingly unsustainable debt/GDP ratios (which show no sign of deleveraging - unlike the US - ignoring unfunded liabilities) with both at just about 500% in total debt/GDP, and yet in general UK trades far better than Japan. McKinsey's 'Debt and Deleveraging' note today points to significant increases in leverage for Japan, Spain, and France (and UK in the middle ground of rises in leverage for now). Of course none of this matters as clearly this debt will never be paid back and/or interest coverage will approach 100% of GDP (and perhaps that is the 100bps premium in CDS for JPY devaluation probability?).
