Investor interest in commodities has reached a multi-year high, according to UBS.
The bank recently published a report outlining 10 key lessons for investors. It covered how commodities work, how they can fit into a portfolio and which behavioral mistakes investors should avoid.
Several factors have revived interest in the asset class. These include persistent inflation risks, geopolitical competition for natural resources and growing attention toward the physical economy.
Investors are also questioning whether bonds still provide the same level of diversification they offered in the past.
UBS Highlights Four Main Reasons to Own Commodities
UBS identified four common arguments for investing in commodities:
diversification, inflation protection, downside protection and return enhancement.
However, the bank offered a balanced assessment rather than a strongly bullish view.
According to UBS, commodities can provide useful portfolio benefits. Still, those advantages depend heavily on market conditions and the way investors gain exposure.
Commodities Can Improve Diversification
Historically, commodities have maintained relatively low correlations with stocks and bonds.
This can make them useful when equities and fixed income move in the same direction. In those periods, commodities may help reduce overall portfolio concentration.
However, UBS warned that these relationships are not always stable.
During severe market downturns, correlations can rise. As a result, commodities may provide less diversification than investors expect at the moment they need it most.
Inflation Protection Comes With Limits
Commodities have also performed well during some periods of rising inflation.
Energy, metals and agricultural products often benefit when prices across the wider economy increase.
However, broad commodity exposure may underperform when inflation is low, stable or falling.
Therefore, investors should not assume commodities will always deliver strong returns simply because they are often described as an inflation hedge.
Gold Offers Stronger Defensive Qualities
The case for downside protection is also mixed.
Gold has historically shown more reliable defensive characteristics than many other commodities. It can benefit from safe-haven demand during periods of market stress.
Energy commodities may also protect investors against supply disruptions and geopolitical shocks.
However, UBS said the defensive performance of the wider commodity market remains inconsistent.
Return Enhancement Depends on Timing
Commodities may improve portfolio returns under certain conditions.
However, the outcome depends heavily on the starting allocation, the investment period and the structure of the futures market.
UBS highlighted roll yield as an important factor.
Roll yield refers to the gain or loss created when investors replace expiring futures contracts with new ones. It can vary significantly and may either support or reduce returns.
UBS Suggests a Modest Commodity Allocation
For investors seeking commodity exposure, UBS recommends a relatively small position.
A low- to mid-single-digit allocation may be appropriate for investors who can tolerate periods of weak performance.
This level of exposure could provide some diversification and inflation sensitivity without allowing commodities to dominate the portfolio.
However, investors should be prepared for long periods when commodities lag behind stocks or bonds.
Diversified Futures Exposure May Be the Simplest Approach
UBS said a diversified and regularly rebalanced commodity futures portfolio may be the easiest way to capture broad exposure.
This approach spreads risk across several commodity groups, including energy, metals and agriculture.
It can also reduce dependence on the performance of a single commodity.
By comparison, targeted positions may offer stronger returns when the investment thesis is correct. However, they also involve higher volatility and greater execution risk.
How Investors Fund the Allocation Matters
UBS also examined whether investors should fund a commodity allocation by reducing bonds or equities.
Funding the position from bonds may help preserve overall portfolio volatility. However, it can also increase the risk of underperformance during periods of falling inflation.
Funding the allocation from equities may reduce exposure to stock market risk. However, it could also affect long-term growth potential.
Therefore, the right approach depends on the investor’s objectives, risk tolerance and existing portfolio structure.
Commodities Offer Benefits, but Not Without Risk
UBS concluded that commodities have historically provided diversification and some protection against inflation.
However, neither benefit is guaranteed.
Performance can vary widely depending on economic growth, inflation, supply conditions and investor positioning.
For that reason, commodities may be most useful as a modest supporting allocation rather than the main driver of a portfolio.
Investors should also be prepared for extended periods of underperformance and significant short-term volatility.
