Core Viewpoints of the Report - Last week, the central bank announced in advance a 1 - trillion - yuan outright reverse repurchase operation, leading to a loose funding situation. However, the progress of the trade - war negotiation remained unclear, resulting in a slight increase in the bond market and also a small rise in ultra - long bonds. The trading activity of ultra - long bonds decreased slightly last week but was still relatively active. The term spread and variety spread of ultra - long bonds narrowed [1][3][11][41]. - For the 30 - year treasury bond, as of June 6, the spread between the 30 - year and 10 - year treasury bonds was 22BP, at a historically low level. In April, the economy showed resilience, with the estimated GDP year - on - year growth rate at about 4.1%, down 0.8% from March but still higher than the annual economic growth target. The CPI in April was - 0.1% and PPI was - 2.7%, indicating obvious deflation risks. With the recent phased easing of Sino - US trade frictions, investors' pessimistic expectations have dissipated. The short - term focus will return to China's second - quarter economic data. It is expected that as the policy support effect weakens, the probability of a decline in bond yields is greater. However, the current term spread of the 30 - year treasury bond is still low, with limited term spread protection [2][12]. - For the 20 - year CDB bond, as of June 6, the spread between the 20 - year CDB bond and the 20 - year treasury bond was 1BP, at a historically extremely low level.

But the current variety spread of the 20 - year CDB bond is still low, with limited variety spread protection [3][13]. 3.
