Recently, some friends asked me how to invest in crude oil. I found that many people only know about crude oil futures but are unaware of more user-friendly options like crude oil ETFs. Rather than saying that crude oil ETFs are a new thing, it's better to note that they've been quietly operating in the market for over 20 years—they were established in 2005, coinciding with the global economic recovery at that time.

Simply put, crude oil ETFs don't actually store barrels of oil at home; instead, they track oil prices indirectly by investing in crude oil futures or derivatives. The best part is that they are traded on exchanges, with buying and selling methods as simple as trading stocks—no need to open a separate futures account, which is truly a blessing for retail investors. Later, inverse and leveraged ETFs emerged, allowing 2-3 times long or short positions, making investment choices more flexible.

In Taiwan, there are mainly a few options. Yuanta S&P Oil ETF (00642U) is the only financial product directly related to crude oil in Taiwan, tracking the S&P Goldman Sachs Crude Oil ER Index, with a correlation to spot prices as high as 0.923, and an expense ratio of 1%. If you're bullish on Brent crude oil, JKoen Brent Oil Bull 2 (00715L) is Taiwan's first ETF tracking Brent crude oil with 2x leverage, also with a 1% expense ratio. The US market offers more choices: the Global X MLP ETF (MLPX) tracks oil and natural gas pipeline companies, with an annual dividend yield of 10.1% and assets under management of $506 million. iShares Global Energy ETF (IXC) holds major energy stocks like ExxonMobil and Chevron, with an annual dividend of 11.88%. The largest is the State Street SPDR Energy Select Sector Fund (XLE), with $8.3313 billion in assets, an annual dividend of 15.57%, mainly composed of Chevron and ExxonMobil.

Besides ETFs, there are other ways to invest in crude oil worth understanding. Crude oil futures are the most direct commodity trading method, with extremely high liquidity but also high barriers to entry, making them less suitable for small and medium investors. If you have research capabilities, investing in oil stocks is also an option, requiring in-depth analysis of company production potential, macro energy environment, and financial performance. Major oil companies include Sinopec, ExxonMobil, Royal Dutch Shell, BP, and TotalEnergies, which are the main targets for crude oil stock investments.

Options trading is similar to futures but offers more flexibility, allowing you to choose not to close positions if your predictions are wrong, risking only the premium paid. Contracts for Difference (CFD) are another popular option, allowing leveraged trading of crude oil with margin, for example, opening a position with just 5% margin. CFD platforms usually do not charge commissions, profit from the spread, and do not have the standard lot size restrictions of futures. However, note that CFDs are leveraged products with significant risks, so proper stop-loss and take-profit settings are essential.

Why do so many people prefer ETFs? First, they are traded on stock exchanges, making operations simple without needing to open a separate futures account. Second, ETFs diversify risk compared to individual oil stocks, offering higher liquidity and enabling frequent intraday trading. Tax-wise, they only incur capital gains tax upon sale. In terms of costs, crude oil ETFs typically have management fees of 0.3%-0.4%, saving about 2%-3% compared to average costs of futures and oil stocks, and they eliminate physical storage and custody fees. They are flexible to operate, supporting both long and short positions. Overall, crude oil ETFs retain some advantages of futures but with much lower liquidation risk and more accessible investment thresholds.

Of course, investing in crude oil ETFs also involves risks. First, price volatility can be affected unexpectedly by international political events and environmental issues, making oil price prediction very challenging. Second, futures are more actively traded than ETFs, attracting large institutions. If you lack experience or understanding of basic crude oil contract concepts, the risks are higher. Some crude oil ETFs track small and medium-sized US shale gas companies, which tend to be less competitive and more vulnerable to collapse during oil downturns. Another often overlooked issue is rollover costs; ETFs tracking crude oil futures incur high rollover costs, making them unsuitable for long-term holding.

If you want to invest in crude oil ETFs, I recommend a diversified portfolio strategy. Since ETFs can be bought and sold like stocks, you can adjust your holdings based on market conditions. For example, to stabilize your portfolio, you might sell some crude oil ETFs to reduce downside risk. If you hold long positions in a few oil stocks, you can use ETFs for hedging. Inverse ETFs are also an option, which can profit from falling oil prices but carry extremely high risks—if oil prices rebound, you could lose everything. When choosing ETFs, be sure to select large, reputable institutions with strong research systems, as they are more sensitive to oil market price movements and offer better capital security.
