Essential differences between CDs and bonds Before looking at how the numbers stack up these days, it is worth reviewing some of the essential differences between CDs and Treasury bonds:
- Cost of access. CDs are typically very easy to access, with no fees and usually fairly low minimums. Buying Treasuries is likely to involve some trading costs if you do it directly, or management fees if you buy them via a mutual fund.
- Reaction to interest rate changes. The value of Treasury securities moves up and down due to changes in market interest rates, while your CD will not change in value other than with the accumulation of interest. However, if you hold your Treasury securities to maturity, the interim fluctuations won't matter much because you will get the face value of the bond at the maturity date.
- U.S. government guarantee. Both Treasuries and deposit accounts are backed by the U.S. government, but with deposit accounts, the guarantee is limited to $250,000.
- Market inefficiency. On any given day, Treasuries will cost pretty much the same no matter where you buy them, while there are significant differences in CD rates from one bank to another, which makes shopping around worthwhile.
CD rates vs. bond yieldsSo which has the advantage -- Treasuries or CDs? It depends very much on the length of time.
As of the beginning of June, one-month CDs and Treasuries had similar yields, with the average CD offering 0.05 percent and the average Treasury yielding 0.04 percent. As you start to move a little further out though, CDs begin to show an advantage. Three-month, six-month, and one-year CDs were all offering exactly twice the yield of their U.S. Treasury counterparts. For example, one-year CDs were offering 0.20 percent while the yield on one-year Treasuries was 0.10 percent.After one year though, the advantage flips to Treasuries. Two-year Treasuries are yielding 0.38 percent, compared to 0.33 percent for the average two-year CD. The advantage for Treasuries is a little wider for three-year maturity dates, and by the five-year mark, Treasury yields are roughly double CD yields, with 1.53 percent for Treasuries and 0.72 percent for the average five-year CD. All things considered then, if you are investing for one year or less, you will probably do better with an average CD than a Treasury bond. For longer-term commitments, it might be worth looking at Treasuries instead. However, if you're willing to shop around, you're likely to find CD rates that outpace these national averages and maybe even the yields on Treasuries of the same length. Just be sure to review all of the terms on any prospective account -- including the early withdrawal penalty, which could become important if rates rise before your maturity date -- before you make your deposit.
