The key differences between iShares Silver Trust (SLV +0.76%) and iShares Gold Trust (IAU +0.12%) are cost, recent performance, and risk profile, with SLV carrying a higher expense ratio and more volatility, while IAU is larger and more affordable.
The BlackRock-run funds are designed to track the price of a single precious metal — silver for SLV, gold for IAU — making them popular options for investors considering alternatives to stocks or bonds. Comparing these two exchange-traded products highlights key differences in fees, volatility, and long-term performance.

What’s inside
iShares Silver Trust provides direct exposure to the price of silver, tracking the metal’s spot price for nearly 20 years. All assets are allocated to the silver metal, under the commodities asset class, with no other holdings. As a result, there are no notable quirks, such as leverage or currency hedging, to note.
By contrast, iShares Gold Trust offers exposure to gold prices. This fund also falls under the commodities asset class, with 100% of its assets in physical gold bullion, with no other holdings. Like SLV, the ETF is structured as a trust rather than a traditional equity fund.
Both funds aim to mirror their respective metals’ price performance and do not introduce additional asset class tilts or complexity.

Foolish take
Examining the price performance of both metals over the last five years, the prices of both silver and gold have appreciated almost in tandem, with gold slightly outperforming silver. Yet over more extended periods, such as over 15 years or more, the yellow metal’s price returns have handily outperformed its poorer cousin.
Moreover, gold prices have been more stable compared to silver. This stability often means that gold is used as an inflation hedge and as a safe-haven asset during economic uncertainty.
Accordingly, the iShares Gold Trust appears to be a better choice compared to its counterpart. The above price dynamics for gold translate to a lower expense ratio for this fund versus SLV.
If you are investing for the long term, an inflation hedge and safe-haven asset should figure in your investment portfolio. Depending on your risk appetite and investment horizon, an investment in precious metals could comprise between 5% and 15% of your total portfolio value.
The primary objective is to preserve capital from inflationary pressures. Additionally, gold has performed well during stock market drawdowns, ensuring peace of mind in times of turmoil.
If you aren’t in a position to invest in physical gold directly, the iShares Gold Trust ETF is an excellent option.
