It applies the approach to two marketwide European portfolios represented by two frequently traded iTraxx Europe CDS indexes, and the resulting analytical default probability term structures are updated on a daily basis. Such instantaneous default probability term structures should be useful not only for risk managers in commercial banks but also for hedge funds and others involved in speculation and arbitrage, as well as for supervisory authorities such as central banks in their quest for financial stability.
