The Dangers of Investing in Cash for the Long-Term

In today’s financial landscape, many individuals are considering the allure of cash investments as a safe haven for their hard-earned money. While the appeal of easy-access savings accounts offering interest rates of around 5% is evident, it’s crucial to understand the potential dangers associated with investing in cash for the long-term. In this article, we explore why relying solely on cash for extended periods can be a high-risk financial strategy.

The Current Temptation: Cash vs. Investments

A growing number of investors are questioning the merits of investing in ‘risk assets’ such as stocks (equities), bonds, and property and comparing this to the perceived safety of cash investments. The uncertain investment climate has prompted some individuals to either delay new investments, increase cash holdings, or withdraw from higher-risk investments.

While investing in cash provides security and low risk, this strategy typically yields lower returns compared to riskier options like equities and bonds. Moreover, cash interest rates may struggle to keep pace with inflation, potentially eroding the purchasing power of savings over time.

A Historical Perspective: The Power of Investments

Historically, long-term investing in risk assets such as stocks and bonds has proven to be an effective strategy. These investments have not only beaten inflation but also delivered superior returns for investors. Cash savings, while secure, often fail to match the financial growth potential offered by riskier investment options.

The chart below shows the total return of global equities (as measured by the MSCI World Index) vs cash (as measured by the Bank of England base rate plus 1%) over the past 20 years.

For over a decade following the 2008 financial crisis, global stock markets enjoyed a remarkable bullish run, consistently delivering positive returns. This extended period of prosperity lured many investors into equities, especially as savings account interest rates remained meagre.

A Shift in Perspective: Recent Market Developments

However, since December 2021, global stock markets have experienced a downturn, causing investors to reassess the attractiveness of equities versus cash holdings. Central banks, including the Federal Reserve and the Bank of England, have responded to rising inflation by increasing interest rates, dispelling the notion that inflation would be transitory.

Banks and building societies are now actively promoting higher savings rates after years of offering minimal returns, irrespective of the investment term.

Overcoming Bias: The Recency Effect

Investors are not immune to biases, and one that often affects them is ‘recency bias’, which involves assuming that current market conditions will persist indefinitely. When markets rise, investors flock to invest more in anticipation of continued growth. Conversely, market downturns make it challenging for investors to allocate funds to equities, even though lower prices may present attractive buying opportunities and therefore be a boost to returns over the long-term.

The Consistency of Cash

While cash is undoubtedly an essential asset class, it should not be the sole focus of long-term investment planning. It has its role in a diversified investment portfolio but should be carefully evaluated against the benefits of other asset classes based on the anticipated investment horizon, the relative attractiveness of long-term returns and the investor’s specific investment objectives.

Timing Difficulties

Most investors understand that holding their assets in cash over the long-term is unlikely to be a good strategy. However, some are tempted to switch to cash as deposit rates rise and when they perceive ‘risk asset’ markets (such as the stock market) may be set to fall or stagnate.

This presents several difficult challenges. The first is how and when to switch to cash. Should this be done at a specified time or slowly drip-fed? At what point should this be done? What if markets have just fallen, locking in losses, before switching to cash? These are the first set of difficult questions. There are the decisions about how to re-invest when a decision is taken to ditch the cash. When should this be done? When cash rates drop below a certain level or when the stock market has risen by x%? With the benefit of hindsight, these questions become easy, but the reality is they are almost impossible to call correctly. History has shown that many investors who switch to cash temporarily end up staying too long and waiting for investment markets to pick up before investing, thus missing out on this growth.

The Multi-Asset Solution

In light of these considerations, a well-rounded approach to investing is often the most prudent choice. Multi-asset investment strategies combine a wide range of assets so investors are not overly exposed to any one asset class. This can both reduce risks and boost long-term investment performance.

Over time, portfolio managers can adjust asset allocations to reflect changing economic conditions and asset prices to maximise the investment opportunities available.

In Conclusion: Seek Professional Advice

In summary, while cash has its merits, it should not be the exclusive focus of a long-term investment strategy. Investors must carefully evaluate the potential risks and returns associated with cash holdings versus riskier asset classes and always have a strong focus on the long-term. Avoiding short-term decision-making is one of the most important factors for success in investment planning.
