Abstract: With the recent development of the European debt crisis traditional index bond management has been severely called into question We focus here on the risk issues raised by the classical market capitalization weighting scheme We propose an approach to properly measure sovereign credit risk in a fixed income portfolio For that we assume that CDS spreads follow a SABR process and we derive a sovereign credit risk measure based on CDS spreads and duration of portfolio bonds We then consider two alternative weighting methods which are fundamental indexation and risk based indexation Fundamental indexation is based on GDP indexation whereas risk based indexation uses a risk budgeting approach based on our sovereign credit risk measure We then compare all these methods in terms of risk diversification and performance We show that the risk budgeting approach is the most appropriate scheme to manage sovereign credit risk in bond portfolios and gives very appealing results with respect to active management of bond portfolios
