Why Should I be Extremely Careful with Commodities ETFs?

Understanding Commodity ETFs

Commodity ETFs serve as a gateway for investors to gain exposure to the commodities market. They offer an opportunity to invest in everything from precious metals to oil and gas. However, unlike traditional stocks and bonds, these ETFs operate within a unique space, bringing their own set of complexities and risks. Let's dissect some of these peculiarities.

The Intricate Dance of Ownership and Timing

When dealing with commodities, the focus is not just on what asset is owned, but also when it is owned. Unlike a company's stock, which can be held indefinitely, commodities contracts have expiration dates. Commodity ETFs, like the Crude Oil Index, don't physically amass the commodities they track - they aren't filling storage units with millions of barrels of oil. Instead, they purchase financial instruments, such as futures contracts, that theoretically should mirror the price of the commodity.

The Challenge of Contango

Here's where it gets tricky: the price of the financial instruments an ETF holds can significantly deviate from the price of the underlying commodity. This phenomenon is known as "contango." Contango occurs when the futures prices for a commodity are higher than the expected spot price at contract maturity. When futures contracts are rolled over to the next month, the process may lead to losses if the next month's contracts are more expensive - a discrepancy that can distort the ETF's price and performance.

The 'Gold' Illusion

Another concern emerges when ETFs claim to possess physical quantities of the underlying commodities, like gold. Technically, shareholders can exchange their shares in a gold ETF for physical gold, but uncertainties lurk beneath the surface. Rumors persist that these ETFs might not hold enough physical gold to cover all the outstanding shares. While these rumors are unverified, the mere possibility of such a scenario should give investors pause.

The Guiding Principle

Remember, when it comes to investing, 'being safe than sorry' is a prudent mantra. Although commodity ETFs provide an accessible route to diversify your investment portfolio, understanding their complexities is vital. Always scrutinize the underlying assets, trading strategies, and associated risks of an ETF before investing.

Tread with Caution

Investing in commodity ETFs can be an exciting venture into the world of commodities. However, their unique structure and the peculiarities associated with commodities trading call for meticulous understanding and extreme caution. As an investor, acknowledging these complexities can better equip you to navigate the fascinating, but sometimes volatile, terrain of commodities ETFs.

The Impact of Market Conditions

The nature of commodities and the dynamics of the market can significantly impact the value of commodity ETFs. Factors such as supply and demand, geopolitical events, and weather can lead to price volatility. This can be appealing to investors looking for opportunities to profit, but it can also lead to potential losses. It's essential to monitor these conditions closely and adjust your investment strategy as needed.

The Expense Factor

Commodity ETFs often come with higher expense ratios compared to other ETFs, mainly due to the cost of rolling futures contracts or storing physical commodities. These expenses can eat into your returns over time. Hence, it's crucial to consider the expense ratio when selecting a commodity ETF.

Diversification and Liquidity Concerns

While commodity ETFs provide a certain level of diversification, they are not without limitations. Some commodity ETFs focus on a single commodity or a narrow sector, exposing investors to sector-specific risks. Moreover, liquidity can also be a concern for some commodity ETFs, especially those tracking less popular commodities. Low liquidity levels can lead to wider bid-ask spreads, making these ETFs more expensive to trade.

Investing in commodity ETFs can be a rewarding strategy if done with care and caution. They offer the allure of high potential returns and portfolio diversification. However, the complexities, including contango, potential discrepancies in physical holdings, high expenses, and liquidity issues, demand keen attention and understanding.

The world of commodities ETFs is complex and fraught with unique challenges. Therefore, it's advised to do your homework, stay informed about market dynamics, and possibly consult with a financial advisor before venturing into this exciting but demanding segment of the investment world.


There are some things to keep in mind when investing in commodities and their ETFs. Most commodities trading revolves around who owns a hard asset and when.

ETFs occupy a space in the commodities world that is somewhat unique. An ETF such as the Crude Oil Index does not physically buy millions of barrels of oil and store them. It buys financial instruments which theoretically should reflect the price of oil.

The problem with such a strategy is that since ETFs do not take physical delivery of the underlying commodity, the instrument they use might significantly diverge from the price of the commodity.

There is a phenomenon is known as “contango,” which can significantly alter the price of the ETF and cause a divergence between the price of the ETF and the underlying commodity. The second area of concern with commodities ETFs is when they claim to be in possession of physical quantities of the underlying commodities, such as gold.

While we aren’t accusing the companies who run such ETFs of misleading their investors, there are abundant rumors that they don’t have enough of the physical commodity to cover the amount of outstanding shares. Technically speaking, you can exchange the shares of a gold ETF for physical gold, but it is not clear what would happen if everyone asked for their physical gold at once.

Again, we don’t know that there is any merit to these rumors, but sometimes it is better to be safe than sorry.
