Investing in Utilities may sound to most people something of a backwater however Utilities provide some of societies most essential services, including power, gas and water distribution, services without which a modern society cannot function. Utilities are natural monopolies and are highly regulated, which results in them having stable earnings, regardless of whether economic conditions are strong or weak. Whilst in a recession households will cut back on discretionary spending on goods and services like cars and holidays, they don’t cut back on their consumption of power, don’t use less gas to heat their homes and don’t cut back on how much water they use, which is why an investment in utilities is less risky than an investment in equities.

Also what is less well known is that over the last few decades utilities have delivered returns significantly in excess of the returns on equities to those fortunate enough to hold them. Until recently, investors have not been able to invest in a globally diversified portfolio of listed utilities, because, with the exception of the United States, in most countries these assets were owned by governments. It was not until the large-scale privatisations of utilities in the late 1980’s and the 1990’s in Europe that investors have been able to invest in utilities located all across the world.

So through the WIOF Global Listed Utilities Fund, one can invest in a highly specialised fund, which moves investment into Utilities around the globe, using the expertise of one of the best Investment Managers in this field of investment. The fund itself provides extended investment opportunities in the Utilities and can help to diversify ones portfolio. Utilities have shown resilience in these times of financial crisis leading to stable income and thus strong share support.


Over the last twenty years, the utilities sector has outperformed global equities markets by an average of over 2% per annum and with a lower standard deviation of returns. Had an investor invested USD10,000 in the UBS Developed Infrastructure and Utilities Index in 1990 - the most widely accepted benchmark for the performance of the utilities sector globally and the benchmark used by the fund, it would be worth USD48,394 today. In comparison, had that USD10,000 been invested in the MSCI Global Equity index in 1990 - the most widely accepted benchmark for the performance of world equity markets, it would be worth only USD32,314 today.

What is also important for investors to realise is that the utilities sector tends to outperform the rest of the equities market more when economic conditions are weak and when stock markets perform poorly. Over 2008 and 2009, as most of the world slipped into a deep recession, the profits earned by the companies in our portfolio were not greatly affected. In fact, over this period, most of the companies in our portfolio actually increased the dividends they paid to investors.

Annual Return for Global Utilities vs. Global Equities: 1990 - 2010


The utilities sector includes both regulated electricity, gas and water utilities (the transmission and distribution systems for electricity, gas and water) – which are natural monopolies and unregulated power generation companies - which operate in a highly competitive environment. Because utilities are natural monopolies, the prices they charge for their services are strictly regulated. It is in understanding this regulation, which is the key to understanding why utilities have performed so well and are likely to continue to do so, regardless of the strength of the economies they operate in.

In most developed countries, government regulation sets the prices a utility can charge at a level which enables them to re-coup all the costs associated with providing these services to the public and also earn a return on equity of around 10% per annum. Over the last few decades, an investment in a global portfolio of regulated electricity, gas and water utilities would have typically earned investors a return around 10% per annum, whilst an investment in a global portfolio of unregulated power generation companies would have earned substantially less. An investment in our benchmark index – the UBS Developed Infrastructure and Utilities Index, which represents a combined portfolio of both regulated utilities and unregulated power generation companies, would have earned around 8-9% per annum. We prefer to invest in regulated utilities rather than in unregulated power generation companies, which is one of the ways we seek to mitigate risk and is also one of the reasons why our fund has tended to outperform our benchmark.

The returns on equity that governments have allowed utilities to earn have been stable over a long period of time, particularly in the United States, with utilities having been listed for significantly longer. The graph below show the average allowed return on equity for listed electricity and gas utilities in the United States over the last fifteen years (the top two blue lines), compared to the yields on the bonds issued by those same companies (the middle two blue lines) and the yields on US government 30 year treasuries (the bottom yellow line).

Regulator Allowed Returns on Equity for United States Electricity and Gas Utilities since 1993

A 10% return on equity is a highly attractive return on capital for a sector which has such stable demand for its services and which does not face competition. Governments allow utilities to earn such a generous return on equity for two reasons, because of the need to provide privatised utilities with enough incentive to undertake the massive level of investment constantly required in this sector and because of the negative social and political consequences of under investment in the infrastructure that delivers these essential services.

The amount of investment required to maintain and upgrade these electricity, gas and water distribution networks is huge. An estimated two trillion US dollars will need to be invested in the electricity transmission system of the United States over the next two decades just to be able to maintain the current level of reliability of the electricity grid. Now that these utilities are privately owned, governments have no choice but to set prices in a way that ensures these utilities are rewarded not only for investing in new infrastructure but also for maintaining their current infrastructure. If prices are set too low and utilities are not able to achieve a healthy return on equity, they will under invest, and deliver unreliable electricity, gas and water services – a poor outcome for society and for politicians who want to appeal to the voting public as skilful administrators delivering rising living standards to their constituents.
