What this means for investors
Many investors look to the bond market as a way to add diversity, income, and capital preservation to their portfolio. Bonds are basically certificates of debt, issued either by companies or governments, and have different times to maturity. Both BSV and IGSB hold short-term bonds, meaning debt that matures within one to five years. Short-term bonds are less sensitive to interest rates than their medium- or long-term counterparts, but they often offer lower yields.
Choosing between BSV and IGSB is primarily about whether you want to hold both corporate and government bonds in one investment, or simply opt for corporate bonds. Government bonds are the least risky debt you can invest in, but they also come with some of the lowest interest payments. That’s why BSV’s dividend payout is slightly lower than IGSB’s, which only holds corporate bonds. The trade-off for that higher dividend payout is the slightly elevated risk you take on by investing in corporate debt — there’s always a chance a company runs into financial distress and defaults on its loan.
For most people seeking security with a little reliable income, IGSB is the better choice in this matchup. The debt it holds is investment grade and issued by some of the giants of the industry. That makes a chance of default unlikely, and the payout that much more attractive.
