Oil ETF Comparison: How to Invest in Commodities and Oil Prices
This article was created with the help of artificial intelligence.
Key Takeaways
- Pure oil ETFs are not permitted in the EU due to UCITS diversification requirements, forcing investors to choose oil ETCs or broad commodity ETFs instead.
- Total expense ratios for oil investments vary between 0.25 and 1.20 percent per year, with cheaper options providing significant long-term return advantages.
- Commodity ETFs operate through futures contracts and face roll losses during contango periods, which can cost two to five percentage points of annual returns depending on market conditions.
- Oil is traded in US dollars, creating currency risk for euro investors that can be eliminated with more expensive currency-hedged variants.
- As a portfolio supplement, oil investments should comprise a maximum of five to ten percent and are unsuitable for long-term buy-and-hold strategies.
Oil ETF Comparison: How to Invest in Commodities and Oil Prices
An oil ETF comparison quickly reveals a peculiarity: in the EU, there are no pure oil ETFs. The UCITS Directive requires a minimum level of diversification, which is why investors track the oil price through oil ETCs. Those wanting broader diversification turn to commodity ETFs, which contain an entire basket of energy, precious metals, and agricultural raw materials. Both approaches have their own rules, costs, and drawbacks.
Commodity ETFs at a Glance
Commodity ETFs track a broad basket of goods. They combine energy, precious metals, industrial metals, and agricultural raw materials into a single security. For retail investors, they are often an easier entry point than purchasing individual futures contracts. Value development follows a commodity index, not a single commodity.
The Key Points
- In the EU, there are no pure oil ETFs, only broad commodity ETFs or individual oil ETCs.
- The total expense ratio of common oil investments ranges from 0.25% to 1.20% per year.
- Oil in US dollars creates a currency risk for euro investors.
- Commodity ETFs are suitable as a supplement, not as a core holding.
What is a Commodity ETF?
A commodity ETF is an index fund that replicates the price development of multiple raw materials. It does not physically invest in barrels of crude oil or gold bars, but rather uses futures contracts. This structure makes it tradable and liquid on the stock exchange. Investors purchase shares like a stock through their deposit.
Differences Between ETF and ETC
The most important difference concerns the legal structure. An ETF is a segregated asset, while an ETC is a debt security. With an ETC, there is a theoretical issuer risk, which is mitigated by collateral. Oil ETCs specifically track oil prices, while commodity ETFs diversify across many areas.
Why There Are No Pure Oil ETFs
UCITS rules stipulate that an index cannot consist of a single component. A pure oil fund would therefore not be approved. This is why targeted oil price investment occurs through oil ETCs, while commodity ETFs inherently provide the required diversification.
How Do Commodity ETFs Work?
Commodity ETFs track their commodity index through futures contracts. A future is a contract that delivers a commodity at a later date. When a contract expires, the fund must roll into the next one. This process noticeably affects returns.
The Role of Futures
Because storage and transport of oil are expensive, all common oil investments work with futures contracts. Futures bundle supply and demand over time. For the investor, this means the price development of the ETC often deviates from the current spot price.
Contango and Backwardation
When the futures price for later delivery dates is higher than the current price, this is called contango. Rolling into the next contract then incurs roll losses, which erode returns over years and can cost two to five percentage points of yield per year depending on market conditions. In the opposite case, backwardation, roll gains result. This mechanism explains why the price development of a commodity ETF rarely exactly matches the oil price.
Physical and Synthetic Replication
Most oil investments are swap-based and thus synthetic. They deposit collateral that is checked daily, such as cash deposits or high-quality securities. Physical replication is rarely possible with perishable or difficult-to-store raw materials.
What Commodity ETFs Are Available?
The selection ranges from broadly diversified index funds to specialized offerings for individual sectors. Those who understand the differences find it easier to choose the right investment for their portfolio. Internationally, such funds are often simply called commodity ETFs.
Broad Commodity Indices
Broad commodity ETFs cover all major segments. They include energy, precious metals such as gold and silver, industrial metals, and agricultural raw materials. This composition provides diversification within the asset class and dampens volatility in individual commodity markets. In particular, the addition of silver and gold smooths out fluctuations when energy prices swing sharply.
Bloomberg Commodity Index
The Bloomberg Commodity Index is one of the best-known commodity indices. It weights multiple sectors and limits the share of individual commodities to a maximum of roughly one-third per sector, so no area dominates. Many commodity ETFs use the Bloomberg Commodity Index as their foundation. The Bloomberg Commodity Index is also found in the iShares Diversified Commodity Swap UCITS ETF, which ranks among the larger funds by volume.
Energy and Metal Emphasis
Alongside broad funds, there are offerings with a clear focus. Energy ETFs concentrate on oil, gas, and related areas. Such energy ETFs respond more strongly to cyclical demand than a broadly diversified basket. Other funds focus on industrial metals such as copper and aluminum, with copper serving as an economic barometer and aluminum closely tied to industrial production. An L&G All Commodities UCITS ETF, meanwhile, diversifies more broadly across the entire commodity basket.
Oil Stocks Instead of Futures Contracts
Those seeking dividends can invest in oil stocks instead of futures contracts. Such commodity funds invest in companies in the oil and gas industry. These shares move more in line with the overall market and provide distributions, but follow the oil price less directly.
Which is the Best Commodity ETF?
There is no single best commodity ETF. The right choice depends on your investment strategy, risk tolerance, and desired degree of diversification. Important factors are costs, fund volume, and replication method. A clear investment strategy helps filter the multitude of offerings to find the right commodity ETFs.
Costs and Total Expense Ratio
The total expense ratio varies considerably. Inexpensive oil investments start at 0.25% per year, while more expensive hedged variants reach 1.20%. Over an investment horizon of ten years, the difference of roughly one percentage point accumulates noticeably and directly impacts returns. A low cost structure is therefore a strong argument.
Fund Volume and Liquidity
Solid fund volume ensures tradability and reduces the risk of closure. A benchmark of at least 100 million euros applies. The largest oil investments in the market:
- WisdomTree WTI Crude Oil: approximately 973 million € fund volume, TER 0.49%
- WisdomTree Brent Crude Oil: approximately 735 million € fund volume, TER 0.49%
- WisdomTree Bloomberg Brent Crude Oil: approximately 23 million €, TER 0.25%
High fund volume typically means tight spreads and good liquidity on the exchange.
Check Composition and Index
Before purchasing, it is worthwhile to review the composition. A broad index with multiple sectors better distributes loss risk than a fund focused on a single commodity. Examine which commodity indices underlie each fund and how heavily individual commodities are weighted. Major commodity indices such as the Bloomberg Commodity Index or the Refinitiv Core Commodity CRB differ significantly in their sector weighting.
How Can I Invest in Commodities?
Access to commodity markets is through a deposit account at a bank or online broker. After that, you choose between a one-time purchase and regular savings. Both options have their merit.
Lump Sum or ETF Savings Plan
An ETF savings plan distributes investments over time and smooths out volatility. Many ETF savings plans start from as little as one euro per month, with some providers charging no fees.
Those with a larger amount can enter via lump sum. Commodity ETFs with high volatility often benefit from staggered purchases through ETF savings plans, as the average entry price spreads over months.
Reference Grades Brent and WTI
With oil, the reference grade determines price development. Brent comes from the North Sea and is considered the international benchmark for roughly two-thirds of globally traded crude oil. WTI is the American grade. Check before purchasing which contract a fund tracks, as the performance of both grades can diverge.
Distributions or Reinvestment
Many oil ETCs reinvest earnings automatically. With stock-based funds, there are regular distributions instead. Those wanting ongoing income look specifically for distributing funds.
Advantages of Commodity ETFs
Commodity ETFs bring several advantages for a diversified portfolio. They open access to an asset class that often behaves differently from stocks and bonds.
- Diversification: Commodities correlate only partially with the stock market.
- Inflation protection: Rising commodity prices can serve as a hedge during periods of high inflation.
- Easy access: A single security replaces direct trading with futures contracts.
- Liquidity: Trading occurs daily on the exchange through your deposit.
As a supplement, commodity ETFs strengthen the structure of wealth without dominating it.
Protection Against Inflation
In times of rising prices, commodities have historically proven effective as a buffer. For example, the Bloomberg Commodity Index rose roughly 16 percent in the inflationary year 2022, while broad equity indices declined significantly. Energy and industrial metals often respond directly to cyclical demand. This characteristic makes commodity ETFs a building block for protection when classic investments come under pressure.
Limits of Value Development
The advantages have a downside. During upswings, some commodity ETFs underperform the broad stock market. Roll losses and high volatility can further burden performance. This is why the asset class remains a supplement, not a replacement.
Risks in Oil ETF Comparison and Oil Price Investment
Every oil price investment carries specific dangers. Those who understand them make a deliberate choice and avoid unpleasant surprises. A careful oil ETF comparison quickly reveals where the greatest pitfalls lie.
Volatility of Commodity Markets
Geopolitical events, supply and demand, and economic factors strongly move commodity prices. Oil prices have fluctuated considerably in recent years and even fell below zero US dollars for the WTI contract in April 2020. The price development of an oil ETC follows these swings immediately.
Currency and Issuer Risk
Oil is traded in US dollars. For euro investors, this creates a currency risk. EUR-hedged variants eliminate it, but cost more—approximately 0.49% instead of 0.25% TER. With an ETC comes dependence on the issuer, since it is a debt security.
Not a Product for Buy-and-Hold
Due to roll losses, pure oil ETCs are historically not suitable for long-term holding. They require active monitoring. Long-term oriented investors prefer broad commodity ETFs or energy sector stocks.
Practical Tips for Selection
A thoughtful approach reduces the risk of mistakes and improves returns. These steps help with the concrete decision.
- Limit portfolio share: Oil investments should account for a maximum of 5 to 10% of the portfolio.
- Check reference grade: Clarify whether Brent or WTI is tracked.
- Pay attention to roll methodology: Longer-dated contracts cushion contango losses.
- Compare costs: A low total expense ratio pays off in the long term.
- Check fund volume: At least 100 million euros reduces closure risk.
Tip for Beginners
A broad commodity ETF based on the Bloomberg Commodity Index is usually a steadier entry point than an individual oil ETC. It diversifies across energy, precious metals, industrial metals, and agricultural raw materials. Such broadly positioned commodity funds remove individual risks from the portfolio. An ETF savings plan spreads the purchase over time and removes pressure from timing questions. When comparing providers, it is worthwhile to look at an inexpensive online broker that executes such savings plans free of charge.
For Experienced Investors
Those who understand the mechanics of futures contracts can target the oil price. As a supplement for inflation diversification, deliberate investments in an oil ETC make sense, provided the share remains small and the position is reviewed regularly.
Oil ETF Comparison: The Conclusion for Your Portfolio
The oil ETF comparison clarifies the structure: broad commodity ETFs for diversification, targeted oil ETCs for direct oil price investment. Pay attention to composition, costs, and fund volume. As a controlled supplement, these funds strengthen a portfolio without taking on the leading role of stocks and broad index funds.
