New decade, renewed challenges

As the new decade begins, investors face an expanding list of challenges around asset management and portfolio construction. We believe that gold is not only a useful long-term strategic component for portfolios, but one that is increasingly relevant in the current environment (see 2020 Gold Outlook).

The increased relevance of gold

Investors have embraced alternatives to traditional equity and bond investments in pursuit of diversification and higher risk-adjusted returns. The share of non-traditional assets among global pension funds, for example, increased from 7% in 1998 to 23% in 2019 (Chart 1).2 And a similar pattern can be seen in the portfolio composition of individual investors.3

Gold allocations have been recipients of this shift. Gold is increasingly recognised as a mainstream investment as global investment demand has grown by an average of 14% per year since 2001 and the gold price has increased by almost six-fold over the same period.4

The principal factors behind this growth include:

  • Emerging market growth: economic expansion – particularly in China and India – increased and diversified gold’s consumer and investor base
  • Market access: the launch of gold-backed ETFs in 2003 facilitated access to the gold market and materially bolstered interest in gold as a strategic investment, reduced total cost of ownership and increased efficiencies
  • Market risk: the global financial crisis prompted a renewed focus on effective risk management and an appreciation of uncorrelated, highly liquid assets such as gold. Today, trade tensions, the growth of populist politics and concerns about the economic and political outlook have encouraged investors to reexamine gold as a traditional hedge in times of turmoil
  • Monetary policy: persistently low interest rates reduce the opportunity cost of holding gold and highlight its attributes as a source of genuine, long-term returns, particularly when compared to historically high levels of global negative-yielding debt
  • Central bank demand: a surge of interest in gold among central banks across the world, commonly used in foreign reserves for safety and diversification, has encouraged other investors to consider gold’s positive investment attributes.

Gold’s strategic role

Gold is a clear complement to stocks, bonds and broad-based portfolios. A store of wealth and a hedge against systemic risk, currency depreciation and inflation, gold has historically improved portfolios’ risk-adjusted returns, delivered positive returns, and provided liquidity to meet liabilities in times of market stress.

1. A source of returns

Gold is long considered a beneficial asset during periods of uncertainty. Historically, it generated long-term positive returns in both good times and bad. Looking back almost half a century, the price of gold has increased by an average of 12% per year in pound sterling since 1971 when the gold standard collapsed.5 Over this period, gold’s long-term return was comparable to equities and higher than bonds. Gold has also outperformed other major asset classes over the past two decades (Chart 2).

Gold is used to protect and enhance wealth over the long term and it operates as a means of exchange, because it has global recognition and is no one’s liability. Gold is also in demand as a luxury good, valued by consumers across the world. And it is a key component in electronics. These diverse sources of demand give gold a particular resilience: the potential to deliver solid returns in good times and in bad (Focus 2).

Beating inflation, combating deflation

Gold is long considered a hedge against inflation and the data confirms this. The average annual return of 12% over the past 49 years, has outpaced the UK consumer price index (CPI). 

Gold also protects investors against extreme inflation. In years when inflation was higher than 3% gold’s price increased 13% on average (Chart 3). Over the long term, therefore, gold has not just preserved capital but helped it grow. 

Notably too, research by Oxford Economics shows that gold should do well in periods of deflation.7 Such periods are characterised by low interest rates, reduced consumption and investment, and financial stress, all of which tend to foster demand for gold.

**For each year on the sample, real return = (1+nominal return)/(1+inflation)-1.

 

Outperforming fiat currencies

Investor demand has been boosted by persistently low interest rates and concerns about the outlook for the dollar, as these factors affect the perceived opportunity cost of holding gold.

Historically, major currencies were pegged to gold. That changed with the collapse of Bretton Woods in 1971. Since then, gold has significantly outperformed all major currencies as a means of exchange (Chart 4). This outperformance was particularly marked immediately after the end of the Gold Standard and, subsequently, when major economies defaulted. A key factor behind this robust performance is that the supply growth of gold has changed little over time – increasing by approximately 1.6% per year over the past 20 years.8 By contrast, fiat money can be printed in unlimited quantities to support monetary policy, as exemplified by the Quantitative Easing (QE) measures in the aftermath of the global financial crisis.

2. Diversification that works

The benefits of diversification are widely acknowledged—but effective diversifiers are hard to find. Many assets are increasingly correlated as market uncertainty rises and volatility is more pronounced, driven in part by risk-on/risk-off investment decisions. As a result, many so-called diversifiers fail to protect portfolios when investors need them most.

Gold is different, in that its negative correlation to stocks and other risk assets increases as these assets sell off. The 2008-2009 financial crisis is a case in point. Stocks and other risk assets tumbled in value, as did hedge funds, real estate and most commodities, which were long deemed portfolio diversifiers. For example, the FTSE 100 fell by 41% from December 2007 to February 2009. Gold, by contrast increased in price, rising 60% in pound sterling over the same period.9

This robust performance is perhaps not surprising.

Gold has consistently benefited from “flight-to-quality” inflows during periods of heightened risk. It is particularly effective during times of systemic risk, delivering positive returns and reducing overall portfolio losses. Importantly too, gold allows investors to meet liabilities when less liquid assets in their portfolio are difficult to sell, undervalued and possibly mispriced.

But gold’s correlation does not just work for investors during periods of turmoil. It can also deliver positive correlation with stocks and other risk assets in positive markets.

This dual benefit arises from gold’s dual nature: as an investment and a luxury good. As such, the long-term price of gold is supported by income growth. Our analysis bears this out, showing that when stocks rally strongly, their correlation to gold can increase (Chart 5), likely driven by a wealth-effect supporting gold consumer demand as well as demand from investors seeking protection against higher inflation expectations.

The standard deviation is based on the same weekly returns over the full period.

 

3. A deep and liquid market

The gold market is large, global and highly liquid.

We estimate that physical gold holdings by investors and central banks are worth approximately £2.7 trillion (tn), with an additional £700 billion (bn) in open interest  through derivatives traded on exchanges or the over-the-counter market.10

The gold market is also more liquid than several major financial markets, including German Bunds and European stock markets, while trading volumes are similar to the US short-dated Treasuries (Chart 6). Gold’s trading volumes averaged £114bn per day in 2019. During that period, over-the-counter spot and derivatives contracts accounted for £61bn and gold futures traded £51bn per day across various global exchanges. Gold-backed ETFs offer an additional source of liquidity, with the largest US-listed funds trading an average of £1.5bn per day.

The scale and depth of the market mean that it can comfortably accommodate large, buy-and-hold institutional investors. In stark contrast to many financial markets, gold’s liquidity does not dry up, even at times of acute financial stress.

4. Enhanced portfolio performance

Long-term returns, liquidity and effective diversification all benefit overall portfolio performance. In combination, they suggest that a portfolio’s risk-adjusted returns can be materially enhanced through the addition of gold. 

Our analysis of investment performance over the past five, 10 and 20 years underlines gold’s positive impact on an investor's portfolio. For example, the average UK portfolio would have achieved higher risk-adjusted returns if 2.5%, 5.0% or 10.0% of the portfolio were allocated to gold over the past decade (Chart 7). The positive impact has been particularly marked since the global financial crisis.

In addition to historical back-testing, a more comprehensive optimisation analysis based on New Frontier Advisors Resampled EfficiencyTM shows that pound sterling-based investors can benefit from a material enhancement in performance if they allocate between 2% and 10% of a well-diversified portfolio to gold (Chart 8a).11

The amount of gold varies according to individual asset allocation decisions. Broadly speaking however, the higher the risk in the portfolio – whether in terms of volatility, illiquidity or concentration of assets – the larger the required allocation to gold, within the range in consideration, to offset that risk (Chart 8b)

Our analysis indicates that gold’s optimal weight in hypothetical portfolios is statistically significant even if investors assume an annual return for gold of between 2% and 4% – well below its actual long-term historical performance.

This works equally for investors who already hold other inflation-hedging assets, such as inflation-linked bonds,12 and for investors who hold alternative assets, such as commodities (Focus 3), real estate, private equity and hedge funds.13

It includes total returns for a 53% allocation to stocks (32% FTSE 100 Index, 21% FTSE All-World ex UK), 32% allocation to fixed income (22% Bloomberg Barclays UK All Bonds Index, 5% Barclays Global Aggregate Corporate Bonds, 5% Barclays GBP Cash Index), and 15% alternative assets (15% Hedge Fund Research Absolute Return Index). Gold’s performance is based on the LBMA Gold price in pound sterling and the respective 2%, 5% and 10% portfolio allocations come from proportionally reducing all assets.

*Optimisation analysis based on New Frontier Advisors “Resampled Efficiency” using monthly returns from January 2000 to December 2019. Data includes total return indices of FTSE 100 Index, FTSE All-World ex UK Index, Bloomberg Barclays UK All Bonds Index, Barclays Global Aggregate Corporate Bond Index, Barclays GBP Cash Index, Hedge Fund Research Absolute Return Index, and FTSE EPRA Developed Europe REIT Index, as well as spot returns of LBMA Gold Price PM, all in pound sterling. Each hypothetical portfolio type reflects a different allocation to cash, bonds, equities, alternative assets and gold. The labels “Conservative”, “Moderate” and “Aggressive” reflect commonly accepted compositions of hypothetical portfolio types based on surveys from organisations such as PIMFA among others. For example, the “Moderate portfolio allocation” holds approximately 40% in cash and bonds, and 60% in stocks, commodities, hedge funds, REITs and gold.  For each given hypothetical portfolio type in Chart 8a, a given color bar section represents the optimal allocation for a corresponding asset class. The portfolio mix corresponds to the allocations to that delivered the highest risk-adjusted return for the total portfolio based on the optimisation analysis. The gold bars in Chart 8b represent the range of all possible optimal gold allocations for each hypothetical portfolio type, based on variations to the allocation of other assets that would still be fall under a “Conservative”, “Moderate” and “Aggressive” composition, respectively. Generally, higher exposure to equities and similar assets resulted in higher optimal allocations for gold, likely to counterbalance the additional risk incurred.

Conclusion

Perceptions of gold have changed substantially over the past two decades, reflecting increased wealth in the East and a growing appreciation of gold’s role within an institutional investment portfolio worldwide. 

Gold’s unique attributes as a scarce, highly liquid and un-correlated asset prove that it can act as a genuine diversifier over the long term. 

Gold’s position as an investment and a luxury good has allowed it to deliver average returns of approximately 12% for nearly five decades, comparable to stocks and more than bonds and commodities (see Chart 2).

Gold’s traditional role as a safe-haven asset means it comes into its own during times of high risk. But gold’s dual appeal as an investment and a consumer good means it can generate positive returns in good times too. This dynamic is likely to persist, reflecting the current environment of political and economic uncertainty, historically low interest rates and concerns surrounding stock and bond markets (see 2020 Gold Outlook).

Overall, extensive analysis suggests that adding between 2% and 10% of gold to a pound sterling-based portfolio will make a tangible improvement to performance and boost risk-adjusted returns on a sustainable, long-term basis (see Chart 7).
