BlackRock stated that government bonds are no longer a reliable buffer against the sell-off of risky assets such as stocks, and investors should consider using gold and Bitcoin as a supplement to bond investments. Various economies are undergoing a transformation that may continue to change long-term economic trends. In the case of inflation, bonds may not be able to withstand the sell-off of the stock market. Bonds no longer reliably diversify the risk of investment portfolios across a wide range of potential outcomes and scenarios. This requires us to reconsider diversification. Therefore, investors should consider new diversified investment tools such as gold and Bitcoin, although they will not replace bonds.
