With rising inflation and potential increases in bond yields, I think bond funds, rather than US Treasuries, can provide greater flexibility and diversity to mitigate market uncertainties. While US Treasuries are secure government bonds, their fixed interest rates leave them exposed to inflation, so US Treasuries may provide lower yields. On the other hand, bond funds pool investors' funds to create a diverse bond portfolio. Bond funds are preferred for their potential higher returns and risk diversification. Conservative investors looking for safety and predictable income may prefer US Treasuries. Conversely, investors comfortable with a bit more risk and seeking diversification may lean towards bond funds.
