Gold has preserved purchasing power over decades, even centuries. That makes it a logical reserve asset for institutions like central banks, whose investment horizons are effectively perpetual. Most retirees, however, don’t have the luxury of waiting decades for that inflation protection to consistently pay off.
In the meantime, owning gold comes with several trade-offs. Prices can be highly volatile, particularly when speculative enthusiasm is rampant. Moreover, most gold ETFs structured as grantor trusts are taxed as collectibles. That means long-term gains may be taxed at a maximum federal rate of 28%, higher than the 20% maximum rate that applies to most long-term capital gains. On top of that, gold produces no income. Unless you’re willing to periodically sell shares or generate cash flow through strategies like covered calls, it doesn’t naturally support retirement withdrawals.
If my goal were protecting purchasing power during retirement, I’d look elsewhere. Rather than commodities or equities, I’d favor a particular corner of the fixed-income market: Treasury Inflation-Protected Securities, or TIPS. Unlike traditional Treasury bonds, the principal value of a TIPS bond adjusts with changes in the Consumer Price Index (CPI).
As principal rises with inflation, the bond’s coupon payments increase as well because they are calculated as a percentage of that inflation-adjusted principal. TIPS generally outperform when inflation turns out to be higher than investors expected. Personally, I think the era of consistently achieving 2% annual inflation is behind us, at least for the foreseeable future.
While investors can purchase individual TIPS directly from the U.S. Treasury, I prefer using an exchange-traded fund. ETFs simplify diversification, eliminate the need to manage individual maturities, and provide regular income distributions. My preferred choice is the Vanguard Short-Term Inflation-Protected Securities ETF (VTIP).
What is VTIP?
VTIP tracks the Bloomberg U.S. 0-5 Year Treasury Inflation-Protected Securities Index. The short-term focus is what makes this ETF particularly attractive. Many TIPS funds hold securities with much longer maturities. While those funds still provide inflation protection, they also become much more sensitive to interest-rate changes.
That’s important because periods of rising inflation (like 2022) often prompt central banks to raise interest rates, and longer-duration bonds generally experience larger price declines when rates increase. VTIP largely avoids that problem with an average duration of just 2.3 years. The trade-off is that it won’t benefit as much if interest rates fall sharply, but it also limits the downside should rates move higher. As a portfolio of U.S. Treasury securities, credit quality is about as strong as it gets. Every holding carries the backing of the full faith and credit of the U.S. government.
One figure that often confuses investors is the fund’s 30-day SEC yield, currently 1.86%. That number represents the real yield before inflation adjustments. Your actual return consists of both this real yield and the inflation adjustment applied to the underlying TIPS principal. Because future CPI readings are unknown, Vanguard cannot incorporate those adjustments into the quoted SEC yield. Generally speaking, if inflation accelerates, both the principal adjustments and the income generated by the fund should increase accordingly.
Why I Like VTIP
The first reason is simple: risk. Vanguard assigns VTIP a risk rating of just 1 out of 5 based on its historical volatility. For retirees holding significant cash balances that steadily lose purchasing power to inflation, replacing part of that cash allocation with a short-duration TIPS fund can be a sensible alternative while maintaining a relatively conservative risk profile.
The second advantage is tax efficiency. Although VTIP pays distributions quarterly rather than monthly, the income generated from U.S. Treasury securities is generally exempt from state and local income taxes. That can provide a meaningful benefit for investors living in higher-tax states such as California or New York.
No investment perfectly hedges inflation over every time period. Gold certainly has its place, particularly over very long horizons. But for retirees who prioritize preserving purchasing power, generating income, and minimizing volatility, I think short-term TIPS represent a more practical solution.
