The Excess Spreads of 5Y Industrial Bonds and 3Y Urban Investment Bonds Slightly Decreased - AAA 3Y industrial perpetual bond excess spreads remained at 3.82BP, at the 1.32% quantile since 2015; 5Y industrial perpetual bond excess spreads decreased by 0.86BP to 7.65BP, at the 4.18% quantile since 2015 [24]. - Urban investment AAA 3Y perpetual bond excess spreads decreased by 0.65BP to 3.75BP, at the 0.29% quantile; urban investment AAA 5Y perpetual bond excess spreads increased by 0.09BP to 10.21BP, at the 10.93% quantile [24]. 6. Credit Spread Database Compilation Instructions - Market - wide credit spreads, commercial bank secondary and perpetual spreads, and industrial/urban investment perpetual bond credit spreads are calculated based on ChinaBond medium - and short - term notes and ChinaBond perpetual bond data. Historical quantiles are since the beginning of 2015 [28]. - Industrial and urban investment bond credit spreads are compiled and statistically analyzed by Cinda Securities R & D Center, with historical quantiles since the beginning of 2015 [28]. - Specific calculation methods and sample selection criteria are provided, including how to calculate spreads, which samples to select, and which samples to exclude [31].
