Report Industry Investment Rating No relevant content provided. Core Viewpoints The report conducts a preliminary exploration of the pricing rules of secondary and perpetual bonds (referred to as "two - perpetual bonds") issued by state - owned large - scale banks and their association with institutional behaviors. It analyzes the influence of the new VAT regulation on the pricing of new and old bonds, the pricing rules in the primary and secondary markets, and potential trading opportunities [2][11]. Group 1: Bank Sub - debt Subtle Clues - The new VAT regulation took effect on August 8th, dividing the interest income of bonds into taxable and tax - exempt based on the issuance time. To make the after - tax yields of new and old bonds of the same variety with similar remaining maturities and issued by the same entity equal, the coupon rate of new bonds should be higher than that of old bonds. For general financial institutions, the pre - tax yield ratio of new and old bonds should be around 1.068; for asset management institutions, this ratio is 1.034 [2][11]. - After August 8th, three new two - perpetual bonds were issued by large - scale banks. The ratio of the coupon rate to the issuance - day valuation of 5 + 5 - year and 10 + 5 - year secondary capital bonds is 1.035 and 1.071 respectively, indicating that the 10 + 5 - year variety contains more tax cost compensation. The difference between the coupon rate and the valuation of 5 + N - year bank perpetual bonds is only 0.01bp, showing that the tax cost compensation in the pricing of perpetual bonds is not significant [2][15]. - The pricing of new two - perpetual bonds is related to the subscription power of institutions participating in the primary market. For 5 + 5 - year secondary capital bonds, large - scale and city commercial banks' self - operations are net sellers on the first active trading day, while joint - stock banks, funds, and other product categories are net buyers. For 10 + 5 - year secondary capital bonds, city commercial banks, joint - stock banks, and securities self - operations are net sellers, and insurance, funds, and other product categories are net buyers. For bank perpetual bonds, large - scale, joint - stock, city commercial, and rural commercial banks are net sellers, and other product categories, funds, and insurance are net buyers [18][24][32]. Group 2: Review of Two - perpetual Bond Pricing Rules - The pricing logic of new bonds in the cash market is dominated by trading desks. For 5 - year large - scale bank secondary capital bonds, the yield ratio of new and old bonds is generally between 1.03 and 1.04 and shows an upward trend. The slow decline in the valuation of new bonds is due to the immature pricing mechanism after the implementation of the new VAT regulation, which makes investors prefer old bonds [4][42]. - For 10 - year large - scale bank secondary capital bonds, the yield ratio of new and old bonds is concentrated between 1.028 and 1.038 and has decreased significantly compared to the initial listing. After the holiday, the ratio has rebounded, affected by the lower liquidity of new bonds and the increased profit - taking by bank self - operations. The continuous buying by insurance indicates that ultra - long - term secondary bonds still need to stabilize [4][48]. - For large - scale bank perpetual bonds, the yield ratio of new and old bonds fluctuates between 1.015 and 1.022. It is lower than that of secondary capital bonds because the trading volume of bank self - operations and other institutions is relatively small, and the liquidity of perpetual bonds is poor. When funds net - buy new perpetual bonds, the yield ratio of new and old bonds increases; when the selling volume of funds increases, the yield ratio decreases, indicating that new perpetual bonds have better defensive properties [5][55]. Group 3: Some Thoughts on Trading Opportunities - The yield of 5 - year large - scale bank secondary capital bonds fluctuates around the spread range of 10 - year treasury bonds. When the yield breaks through the upper limit of 10 - year treasury bonds + 30bp, the probability of a subsequent rebound increases; when it breaks through the lower limit of treasury bonds + 20bp, the probability of a subsequent correction rises. However, the new bonds issued after August 8th may be affected by the VAT on interest income, which may interfere with the effectiveness of the signal [64]. - One way to deal with new bonds is to convert the yield of new secondary capital bonds through the yield ratio of comparable new and old bonds, but its effectiveness is difficult to verify. Another way is to construct a new rotation signal using new 5 - year secondary capital bonds and 10 - year treasury bonds. The new bond combination will indicate an oversold rebound later and an over - bought defense earlier compared to the initial signal. Institutions with a lower VAT rate can obtain excess tax compensation by investing in new bonds with higher tax compensation [68].
