Advantages of baby bonds
Although the most obvious advantage is affordability, baby bonds also offer a number of potential benefits to their investors. Like regular bonds, baby bonds can provide a steady income stream via regular interest payments.
Baby bonds also offer liquidity, an important benefit in volatile markets. If an investor holding one (or more) of the bonds thinks interest rates will increase, it might be a wise idea to sell since the value of a lower-yielding bond will drop as higher-yielding bonds become available.
It's worth noting that many baby bonds sold by governments are among the safest possible investments you can make. Bonds issued by state governments and municipalities are often exempt from federal taxes, as well.
Finally, baby bonds can be an inexpensive method of diversifying portfolios. Their low prices make it easy for individual investors to gradually add fixed-income securities. And while baby bonds aren't likely to increase in value like a classic growth stock, they're a low-risk means of steadily building wealth over time.
Disadvantages of baby bonds
Baby bonds carry many of the same risks as any fixed-income security. Chief among those risks is the credit rating of the issuer. Junk-grade bonds offer the potential for outsized returns, but could also lead to significant losses.
Baby bonds are generally considered to be unsecured debt. If a borrower defaults, investors holding baby bonds generally have to wait for holders of secured debt to be repaid (although they usually stand to be compensated before holders of preferred stock or common stock).
