While inflation has been getting quite a bit of airtime recently, there’s another topic that is creating discussion amongst the investment community: commodities.

    The term ‘supercycle’ is being mentioned again. The last supercycle was in the 2000’s where China’s rapid growth drove a huge and sustained increase in the price of the commodities fuelling its expansion.  

    Much of the excitement now is linked to rapid gains after last year’s Covid-related slowdown, as well fears around rising inflation given that many believe commodities provide an effective inflation hedge in portfolios.


    Whether commodities are a good investment or not is open to debate but there are a number of fundamental considerations that should be included in any conversation on this asset class. 

    Investing in commodities 

    Investors can gain exposure to commodities either directly, or indirectly.  

    Direct exposure is via: 

    • physical investment in the commodity (like buying gold bullion) 
    • investing in an exchange traded commodity fund 
    • commodity futures, forwards or other derivatives 

    Indirect exposure is via: 

    • investing in commodity-producing companies like gold miners or oil majors 

    Direct Commodity Investing 

    Although it is possible to invest in individual commodities, if you’re investing more broadly, you’ll probably be doing so with reference to a commodity index. The best known of these is the Bloomberg Commodity Index, or BCOM which has the following 23 constituents:

    commodity index

    There are other well-known indices too, like the S&P GSCI. Whilst similar to the BCOM in terms of the commodities it represents, it has a much higher weighting to energy at 54%, so is much more exposed to the oil price than BCOM. 


    The major drawback from investing directly in commodities is that they don’t produce dividends and they don’t produce income. Moreover, they are costly to transport, store and insure.  

    These costs either show up directly (for example the fee you pay to hold your gold bullion in a vault and insure it) or indirectly (futures prices on the derivative exchange are usually higher than current prices to factor in storage costs, which results in ‘roll costs’ when shorter dated contracts are replaced over time with longer dated ones).  

    Quite often when commodity prices are quoted in the press, these costs are ignored, making commodities seem more attractive as investments than they really are. 

    Factoring in costs when investing in commodities (and indeed, in anything else) is extremely important. As of the end of April, spot prices were only 10% off their peak in the Chinese post-financial-crisis-fuelled stimulus highs of 2011.  

    After factoring in costs, the investible BCOM Index is, however, down almost 50% over the same time period. The same effect can be seen when commodities are rallying. Whilst (uninvestable) spot prices increased almost 70% from March 2020 to April 2021 in dollar terms, the investable BCOM only increased 46%. 

    Proceed with Caution 

    So, are commodities a good investment at present? Well, if it transpires that we are in the early foothills of another supercycle, then there could be a lot of money to be made from holding a broad basket of commodities, even after factoring in costs.  

    That said, there is a big difference between ‘trading’, which is short-term in nature, and ‘investing’, which is much more long-term. The lack of yield and significant associated costs do tarnish the attractiveness of commodities as long-term investments.  

    What can be opportunistically attractive to short term speculators like hedge funds and systematic quant traders isn’t necessarily suitable for more patient strategic investors, who may be better off focusing elsewhere.
