The excess spreads of 3Y industrial perpetual bonds have declined, and the excess spreads of urban investment perpetual bonds continue to diverge - Industrial perpetual bonds: The excess spreads of industrial AAA 3Y perpetual bonds have decreased by 1.38BP to 14.79BP compared to last week, at the 38.88% percentile since 2015; the excess spreads of industrial 5Y perpetual bonds are flat at 12.39BP compared to last week, at the 27.07% percentile since 2015 [2][31]. - Urban investment perpetual bonds: The excess spreads of urban investment AAA 3Y perpetual bonds have decreased by 2.04BP to 5.35BP, at the 5.14% percentile; the excess spreads of urban investment AAA 5Y perpetual bonds have increased by 1.83BP to 10.97BP, at the 17.02% percentile [2][31]. 6. Credit Spread Database Compilation Instructions - Calculation basis: The overall market credit spreads, commercial bank Tier 2 and perpetual bond spreads, and urban investment/industrial perpetual bond credit spreads are calculated based on ChinaBond Medium - and Short - Term Notes and ChinaBond Perpetual Bonds data, with historical percentiles since the beginning of 2015; the urban investment and industrial bond - related credit spreads are compiled and统计 by the R & D Center of Cinda Securities, with historical percentiles since the beginning of 2015 [36]. - Calculation methods: Industrial and urban investment individual bond credit spreads = individual bond ChinaBond valuation (exercise) - same - maturity government - developed bond yield to maturity (calculated by linear interpolation method), and then the credit spreads of industries or regional urban investments are obtained by arithmetic averaging; bank Tier 2 capital bond/perpetual bond excess spreads = bank Tier 2 capital bond/perpetual bond credit spreads - same - grade and same - maturity bank ordinary bond credit spreads; industrial/urban investment - type perpetual bond excess spreads = industrial/urban investment - type perpetual bond credit spreads - same - grade and same - maturity medium - term note credit spreads [38]. - Sample selection: Both industrial and urban investment bonds select medium - term notes and public corporate bonds as samples, and exclude guaranteed bonds and perpetual bonds. If the remaining maturity of an individual bond is less than 0.5 years or more than 5 years, it is excluded from the statistical sample. Industrial and urban investment bonds use external entity ratings, while commercial banks use ChinaBond implicit debt ratings [38].
