Gate.io News June 14- So far this year, the return on investment of some bond funds has risen, and the annualized return rate of some products has even exceeded 10%, attracting the attention of many investors. Authorities warn that there are also significant risks behind the bond fund "bull market". This round of bond fund market is closely related to the decline in bond interest rates, and this high yield is not sustainable. Industry experts analyze that usually in the phase of falling interest rates, bond prices rise, and a large amount of funds pour into the bond market, exacerbating the imbalance between supply and demand for bonds, and interest rates further decline, and prices continue to rise, forming a positive feedback effect. Conversely, there will be a negative feedback effect when interest rates rise. The long-term bond yield will not continue to remain low. Investors who buy high in the bond market will face a high risk of investment losses in the future.
