[Some institutions received regulatory reminders to strengthen bond investment risk management] October 15th: Since this week, long-term bond yields have accelerated their decline. As of the close of trading on October 14, the 10-year Treasury bond yield was 1.64%, approaching historical lows. The reporter learned from multiple people familiar with the matter that in response to the recent significant increase in the interest in long-term government bond yield trading, some brokerages and banks have received reminders from regulatory authorities, requiring relevant institutions to strengthen bond investment risk management. Some insiders believe that the central bank has repeatedly stated its stance on strengthening macro-prudential management of financial markets and pays close attention to market operations. We do not rule out subsequent macro-prudential management measures against institutions with aggressive trading behavior. (Reporter Li Ting)
