The Case for Intermediate Treasuries

Taxable Fixed Income

For most conservative investors, an intermediate bond strategy represents a sound choice. There are advantages to this strategy compared with either holding cash or long-term bonds. Intermediate US Treasuries have offered significantly higher historical returns than 30 day T-Bills with little additional risk, and have provided annual returns that are only slightly less than long US Treasuries.

A History of Returns

Fixed Income and Equity returns are readily available for the last 81 years through data compiled by Ibbotson. The table below shows a comparison of returns for Intermediate (5 Yr) and Long (20 Yr) U.S. Treasury bonds for the period 1926-2006.

The Long maturity treasuries outperformed shorter bonds by .30% (5.60-5.30%) annually.

Intermediates, thus, captured about 95% of the return of the Long bonds. During this period, Intermediates outperformed the 20 Year bonds in 44 out of 81 periods or about 54% of the time. Long bonds had 21 periods of negative returns, while Intermediates only had 8. Thus, 5 Yr treasuries had positive returns 90% of the time. The duration or market risk of these bonds is compared in the chart below.

An Intermediate treasury has about 37% of the risk of a Long bond. This implies that the risk/reward of owning Intermediate bonds is very attractive when compared to Long bonds. The chart below shows that Intermediates have captured 95% of the return of Long bonds, while taking only 37% of the market risk during the last 81 years.

Conclusion

Portfolios consisting of intermediate maturity taxable securities are suitable for conservative investors’ fixed-income portfolios. These portfolios have generated positive returns about 90% of the time, are much less risky than portfolios of bonds with long maturities, and capture most of the return of a long bond portfolio. While we cannot guarantee that history will repeat itself, there is certainly a compelling case for investing in Intermediate Bond portfolios. This is a non-market-timing strategy that works well when combined with other riskier asset classes. The bonds provide income and dampen the volatility of the overall portfolio.
