ISA Reform: Will it boost the London Stock Exchange (LSE)?

For a while now, debate has raged over how to revive the fortunes of the London Stock Exchange (LSE). Since the 2008 financial crisis, the market has suffered a lack of investment, poor liquidity and low performance. This has produced a moribund financial market which has become unattractive to both investors and companies. Returns from the UK market lag international competitors, particularly the USA (see the chart).


Investment in the S&P 500 Index over the period would have produced annualised rates of return of 14.35%, more than double that from the FTSE 100 Index. Part of this underperformance is due to the industrial mix of the listed companies: low-growth energy and mining compared to the high-growth technology sectors in the USA. This has led to the perception that London is not a place for firms to list, particularly those in high-growth sectors.

In 2024, 88 companies choose to delist or transfer their primary listing elsewhere. Only 18 took their place. Several big companies from a range of industries, including Ashtead, Flutter and CRH have transferred their primary listing to New York or have plans to do so.

The new Labour government views stimulating higher levels of investment though the London market as an important element in its drive to boost productivity and growth in the UK. Recently, it has been reported that investment institutions have been lobbying the UK government to reduce significantly the tax-free allowance for Cash Individual Savings Accounts (ISAs) as a way to encourage more of UK households’ savings to be channelled through the UK stock market.

Currently, UK savers can save up to £20 000 annually into ISAs without paying tax on the interest earned. This can be held solely in Cash ISAs, or in a combination of Cash plus Stocks and Shares ISAs. The tax-free instruments which were introduced by a Labour government in 1999 to encourage higher savings have proved immensely popular. Data from Paragon Bank indicate that over £350 billion are held in these accounts. However, under the new proposals, the amount which would be allowed to be saved as cash has been rumoured to be cut to £4000 per year, with the hope that some of it will be invested in the UK stock market.

The proposals have proved controversial, with high-profile figures voicing opposition. In this blog, we’ll analyse the reasons behind the proposal and discuss whether it will have the desired effect of stimulating higher levels of investment. We’ll also discuss other proposed policies for making the LSE a more effective channel for investment flows to boost economic growth.

Stock markets and the saving and investment channel

The main reason for the proposed ISA change is to encourage more investment in the UK stock market. By reducing the amount which can be saved in Cash ISAs, the government hopes to encourage savers to invest in Stocks and Shares ISAs instead, particularly ones linked to the UK market. This would increase the amount of finance capital in the market, thereby boosting its liquidity. This would then make it an attractive place for young, vibrant UK and foreign companies to list.

An active, liquid secondary market in shares is important to attract firms to list on stock exchanges by issuing shares to outside investors. Traditionally, this channel has been important to the growth and development of firms.

Existing savings in Cash ISAs are deposited with financial institutions such as banks and building societies. Through the credit-creation process such funds can be used to finance productive investment. In countries like the UK, lending by financial institutions is an important way that investment is financed, particularly for small and medium-sized enterprises. However, scale limits, regulatory restrictions and the need to diversify lending properly means that there are limits to the financing available for company investment through these institutions.

Capital markets like the LSE are intended to meet these larger-scale requirements. Financial claims, such as debt and equity, are divided into atomised instruments and sold to outside investors to fund investment and business growth.

Further, the desire for a capital injection to finance growth is not the only reason that firms seek stock market listings. Founders of companies may have a lot of wealth invested in the equity of their firms. Selling some of their equity to outside investors through a stock market listing is a way of diversifying their wealth. However, if they are to maximise the potential sale price, there must be an active, liquid secondary market to encourage investors to buy shares in the primary market.

Proponents of reform want to encourage a greater appetite for risk among UK investors, which will produce more savings being channelled through the LSE.

One issue is whether savers will respond in the way anticipated and channel more funds through the UK stock market. Many savers like the security of Cash ISAs. Such vehicles offer a low-risk/low-return combination, which savers like because the tax benefits boost returns. A survey by the Nottingham Building Society found that a substantial number of Cash ISA savers are concerned that the proposed changes could affect their ability to save for important financial goals, such as buying a house or building an emergency fund. Higher-risk Stocks and Shares ISAs are not suitable for such savings because of the potential to lose the initial amount invested. Many may not be prepared to do so and one-third suggested they would save less overall.

According to the survey, only 38% of Cash ISA holders said they would consider investing in Stocks and Shares ISAs if the Cash ISA allowance were reduced. It may be difficult to alter such risk-averse preferences given the average amount saved through ISAs and demographics. In 2022/23, the average amount subscribed to ISAs was £5000. This does not suggest that average households have a significant surplus of cash that they may want to investment at a high risk through the stock market. Indeed, many may want to have access to the cash at short notice and so are not prepared to forgo liquidity for the time needed to accrue the benefits of compounding which stock market investing produces.

Demographics may also play a role in this. Many of those who save more are now retired, or near retirement. They are less likely to see the appeal of compounding returns over long periods through investment in shares. Instead, with shorter investment horizons, they may only see the potential for losses associated with Stocks and Shares ISAs. Indeed, they will be starting to liquidate their long-term positions to draw income in retirement. Therefore, they may save less.

For others, who may be prepared to accept the additional risk, with the prospect of higher returns in the way that advocates of the reform hope for, the reduction in the Cash ISA allowance does not necessarily mean that they will invest in Stocks and Shares ISAs linked to the UK market. Since returns from the UK market have lagged international competitors, it may be that savers will channel their savings to those international markets, particularly in the USA, where the risk–return relationship has been more rewarding. Doing so has been made much easier and cheaper through a combination of economic forces including technological advances, regulatory changes and increased competition. This makes it much easier for UK savers to channel investment funds to wherever potential return is highest. At the moment, this is unlikely to be the UK, meaning that the anticipated boost to investment funds may not be as much as anticipated.

Critics of the proposal also question the motives of investment fund managers who have been lobbying government. They argue that the reforms will mean that many people who do now choose to save in Stocks and Shares ISAs will buy funds managed by fund managers who will receive fees for doing so. Critics argue that it is the prospect of higher fees which is the real motive behind the lobbying, not any desire to boost investment and growth.

What alternatives are available to boost the London Stock Exchange

The low valuations of LSE-listed companies compared to their international counterparts, particularly those in the USA, has discouraged growing firms from listing in London. To address this, there have been calls to enhance corporate governance standards and reduce regulatory burdens for listed companies.

This has already been recognised by the authorities. In 2024, UK regulators approved the biggest overhaul of rules regulating London-listed companies. The new listing rules will hand more power to company bosses to make decisions without shareholder votes. They will give companies more flexibility to adopt dual-class share structures used by founders and venture capital firms to give themselves stronger voting rights than other investors. This is particularly popular for founders who want to diversify their wealth without sacrificing control and is used frequently by tech companies and venture capitalists when listing in the USA. Such reforms may attract more companies in high-growth sectors to list in London.

Tax policies which provide the right incentives to buy and sell shares could also encourage more investment in the LSE. For instance, the repeal in the mid-1990s of the preferential tax treatment of dividend income for UK pension funds and insurance companies is seen as a major factor in discouraging those institutions from investing more funds in the London market. Since tax on capital gains is only liable when they are realised, this reduces their present value versus the equivalent amount on dividends.

As the following table illustrates, given the significantly higher percentage of total returns derived from dividends in the LSE compared to other exchanges, the equal tax treatment of dividend and capital gains provides an incentive to seek jurisdictions where capital gains predominate. This is what UK pension funds have done. Data from the Office of National Statistics show that in 2024, 77% of UK occupational pensions equity investments were overseas.

Reinstating this tax benefit could stimulate greater demand for UK equity from this significant sector, boosting liquidity in the London market. Allied to this are proposals from the UK government to consolidate the fragmented UK pension industry to achieve greater scale economies in that channel for investment. This can reduce financing costs, boosting the marginal return from UK investments for these funds, encouraging greater investment in the UK market (ceteris paribus).

Further, the 2.5% stamp duty on share purchases has been viewed as another disincentive for both retail and institutional investors to engage in security trading on the London Stock Exchange. The duty, which is much higher than in peer economies, effectively raises the expected rate of return on UK equites which depresses perceptions of their values and prices. Its removal may raise trading volumes, improving the liquidity of the market and be offset by increased tax revenues in the future. However, the Treasury suggests that the removal of stamp duty is doubtful, since it would create a significant hole in the UK government’s budget.

Ultimately, many of these reforms may have limited impact on investment. Efforts to boost confidence in the stock market will depend on improving the overall economic environment in the UK. Therefore, it will be the wider policies promoting growth in general which will increase the rates of return offered by London-listed firms and be more significant to attracting capital to London.

However, many of these are controversial themselves, such as relaxing laws around planning permissions and addressing business uncertainties around post-Brexit trading arrangements with the European Union. These broader economic measures could help make the UK generally, and the LSE specifically, more appealing to both domestic and international investors.

Conclusion

The UK government’s proposal to reduce the Cash ISA allowance is part of a broader strategy to boost investment in the stock market and stimulate economic growth. While this change could lead to more capital being directed towards productive investments, it also poses challenges for savers who like the security and simplicity of Cash ISAs.

The ultimate impact will depend on how savers respond to these changes. The potential reduction in overall savings rates could counteract some of the intended benefits. Further, the extent to which they are prepared to channel their savings into UK-listed companies will be important. If many seek higher returns elsewhere, the impact on the UK stock market may be limited. In any case, policies to address the problems of the UK stock market will only work if the wider issues associated with UK productivity and growth are addressed.

Investment set to fall as business is baffled by Trump

Economic growth is closely linked to investment. In the short term, there is a demand-side effect: higher investment, by increasing aggregate demand, creates a multiplier effect. GDP rises and unemployment falls. Over the longer term, higher net investment causes a supply-side effect: industrial capacity and potential output rise. This will be from both the greater quantity of capital and, if new investment incorporates superior technology, from a greater productivity of capital.

One of the biggest determinants of investment is certainty about the future: certainty allows businesses to plan investment. Uncertainty, by contrast, is likely to dampen investment. Investment is for future output and if the future is unknown, why undertake costly investment? After all, the cost of investment is generally recouped over several months or year, not immediately. Uncertainty thus increases the risks of investment.

There is currently great uncertainty in the USA and its trading partners. The frequent changes in policy by President Trump are causing a fall in confidence and consequently a fall in investment. The past few weeks have seen large cuts in US government expenditure as his administration seeks to dismantle the current structure of government. The businesses supplying federal agencies thus face great uncertainty about future contracts. Laid-off workers will be forced to cut their spending, which will have knock-on effect on business, who will cut employment and investment as the multiplier and accelerator work through.

There are also worries that the economic chaos caused by President Trump’s frequent policy changes will cause inflation to rise. Higher inflation will prompt the Federal Reserve to raise interest rates. This, in turn, will increase the cost of borrowing for investment.

Tariff uncertainty

Perhaps the biggest uncertainty for business concerns the imposition of tariffs. Many US businesses rely on imports of raw materials, components, equipment, etc. Imposing tariffs on imports raises business costs. But this will vary from firm to firm, depending on the proportion of their inputs that are imported. And even when the inputs are from other US companies, those companies may rely on imports and thus be forced to raise prices to their customers. And if, in retaliation, other countries impose tariffs on US goods, this will affect US exporters and discourage them from investing.

For many multinational companies, whether based in the USA or elsewhere, supply chains involve many countries. New tariffs will force them to rethink which suppliers to use and where to locate production. The resulting uncertainty can cause them to delay or cancel investments.

Uncertainty has also been caused by the frequent changes in the planned level of tariffs. With the Trump administration using tariffs as a threat to get trading partners to change policy, the threatened tariff rates have varied depending on how trading partners have responded. There has also been uncertainty on just how the tariff policy will be implemented, making it more difficult for businesses to estimate the effect on them.

Then there are serious issues for the longer term. Other countries will be less willing to sign trade deals with the USA if they will not be honoured. Countries may increasingly look to diverting trade from the USA to other countries.

A four-day week – a solution to sluggish productivity growth? (Updated)

In a blog from March 2023 (reproduced below), we saw how there has been growing pressure around the world for employers to move to a four-day week. Increasing numbers of companies have adopted the model of 80% of the hours for 100% of the pay.

As we see below, the model adopted has varied across companies, depending on what was seen as most suitable for them. Some give everyone Friday off; others let staff choose which day to have off; others let staff work 80% of the hours on a flexible basis. Firms adopting the model have generally found that productivity and revenue have increased, as has employee well-being. To date, over 200 employers in the UK, employing more than 5000 people, have adopted a permanent four-day week.

This concept of 100-80-100, namely 100% of pay for 80% of hours, but 100% of output, has been trialled in several countries. In Germany, after trials over 2024, 73% of the companies involved plan to continue with the new model, with the remaining 27% either making minor tweaks or yet to decide. Generally hourly productivity rose, and in many cases total output also rose. As the fourth article below states:

The primary causal factor for this intriguing revelation was simple – efficiency became the priority. Reports from the trial showed that the frequency and duration of meetings was reduced by 60%, which makes sense to anyone who works in an office – many meetings could have been a simple email. 25% of companies tested introduced new digitised ways of managing their workflow to optimise efficiency.

Original post

In two previous posts, one at the end of 2019 and one in July 2021, we looked at moves around the world to introduce a four-day working week, with no increase in hours on the days worked and no reduction in weekly pay. Firms would gain if increased worker energy and motivation resulted in a gain in output. They would also gain if fewer hours resulted in lower costs.

Workers would be likely to gain from less stress and burnout and a better work–life balance. What is more, firms’ and workers’ carbon footprint could be reduced as less time was spent at work and in commuting.

If the same output could be produced with fewer hours worked, this would represent an increase in labour productivity measured in output per hour.

The UK’s poor productivity record since 2008

Since the financial crisis of 2007–8, the growth in UK productivity has been sluggish. This is illustrated in the chart, which looks at the production industries: i.e. it excludes services, where average productivity growth tends to be slower. The chart has been updated to 2024 Q2 – the latest data available. (Click here for a PowerPoint of the chart.)

Prior to the crisis, from 1998 to 2006, UK productivity in the production industries grew at an annual rate of 6.9%. From 2007 to the start of the pandemic in 2020, the average annual productivity growth rate in these industries was a mere 0.2%.

It grew rapidly for a short time at the start of the pandemic, but this was because many businesses temporarily shut down or went to part-time working, and many of these temporary job cuts were low-wage/low productivity jobs. If you take services, the effect was even stronger as sectors such as hospitality, leisure and retail were particularly affected and labour productivity in these sectors tends to be low. As industries opened up and took on more workers, so average productivity rapidly fell back. Since then productivity has flatlined.

If you project the average productivity growth rate from 1998 to 2007 of 6.9% forwards (see grey dashed line), then by 2024 Q3, output per hour in the production industries would have been 3.26 times higher than it actually was: a gap of 226%. This is a huge productivity gap.

Productivity in the UK is lower than in many other competitor countries. According to the ONS, output per hour in the UK in 2021 was $59.14 in the UK. This compares with an average of $64.93 for the G7 countries, $66.75 in France, £68.30 in Germany, $74.84 in the USA, $84.46 in Norway and $128.21 in Ireland. It is lower, however, in Italy ($54.59), Canada ($53.97) and Japan ($47.28).

As we saw in the blog, The UK’s poor productivity record, low UK productivity is caused by a number of factors, not least the lack of investment in physical capital, both by private companies and in public infrastructure, and the lack of investment in training. Other factors include short-termist attitudes of both politicians and management and generally poor management practices. But one cause is the poor motivation of many workers and the feeling of being overworked. One solution to this is the four-day week.

Latest evidence on the four-day week

Results have just been released of a pilot programme involving 61 companies and non-profit organisations in the UK and nearly 3000 workers. They took part in a six-month trial of a four-day week, with no increase in hours on the days worked and no loss in pay for employees – in other words, 100% of the pay for 80% of the time. The trial was a success, with 91% of organisations planning to continue with the four-day week and a further 4% leaning towards doing so.

The model adopted varied across companies, depending on what was seen as most suitable for them. Some gave everyone Friday off; others let staff choose which day to have off; others let staff work 80% of the hours on a flexible basis.

There was little difference in outcomes across different types of businesses. Compared with the same period last year, revenues rose by an average of 35%; sick days fell by two-thirds and 57% fewer staff left the firms. There were significant increases in well-being, with 39% saying they were less stressed, 40% that they were sleeping better; 75% that they had reduced levels of burnout and 54% that it was easier to achieve a good work–life balance. There were also positive environmental outcomes, with average commuting time falling by half an hour per week.

There is growing pressure around the world for employers to move to a four-day week and this pilot provides evidence that it significantly increases productivity and well-being.

World Uncertainty Index

We continue to live through incredibly turbulent times. In the past decade or so we have experienced a global financial crisis, a global health emergency, seen the UK’s departure from the European Union, and witnessed increasing levels of geopolitical tension and conflict. Add to this the effects from the climate emergency and it easy to see why the issue of economic uncertainty is so important when thinking about a country’s economic prospects.

In this blog we consider how we can capture this uncertainty through a World Uncertainty Index and the ways by which economic uncertainty impacts on the macroeconomic environment.

World Uncertainty Index

Hites Ahir, Nicholas Bloom and Davide Furceri have constructed a measure of uncertainty known as the World Uncertainty Index (WUI). This tracks uncertainty around the world using the process of ‘text mining’ the country reports produced by the Economist Intelligence Unit. The words searched for are ‘uncertain’, ‘uncertainty’ and ‘uncertainties’ and a tally is recorded based on the number of times they occur per 1000 words of text. To produce the index this figure is then multiplied up by 100 000. A higher number therefore indicates a greater level of uncertainty. For more information on the construction of the index see the 2022 article by Ahir, Bloom and Furceri linked below.

Figure 1 (click here for a PowerPoint) shows the WUI both globally and in the UK quarterly since 1991. The global index covers 143 countries and is presented as both a simple average and a GDP weighted average. The UK WUI is also shown. This is a three-quarter weighted average, the authors’ preferred measure for individual countries, where increasing weights of 0.1, 0.3 and 0.6 are used for the three most recent quarters.

From Figure 1 we can see how the level of uncertainty has been particularly volatile over the past decade or more. Events such as the sovereign debt crisis in parts of Europe in the early 2010s, the Brexit referendum in 2016, the COVID-pandemic in 2020–21 and the invasion of Ukraine in 2022 all played their part in affecting uncertainty domestically and internationally.

Uncertainty, risk-aversion and aggregate demand

Now the question turns to how uncertainty affects economies. One way of addressing this is to think about ways in which uncertainty affects the choices that people and businesses make. In doing so, we could think about the impact of uncertainty on components of aggregate demand, such as household consumption and investment, or capital expenditures by firms.

As Figure 2 shows (click here for a PowerPoint), investment is particularly volatile, and much more so than household spending. Some of this can be attributed to the ‘lumpiness’ of investment decisions since these expenditures tend to be characterised by indivisibility and irreversibility. This means that they are often relatively costly to finance and are ‘all or nothing’ decisions. In the context of uncertainty, it can make sense therefore for firms to wait for news that makes the future clearer. In this sense, we can think of uncertainty rather like a fog that firms are peering through. The thicker the fog, the more uncertain the future and the more cautious firms are likely to be.

The greater caution that many firms are likely to adopt in more uncertain times is consistent with the property of risk-aversion that we often attribute to a range of economic agents. When applied to household spending decisions, risk-aversion is often used to explain why households are willing to hold a buffer stock of savings to self-insure against unforeseen events and their future financial outcomes being worse than expected. Hence, in more uncertain times households are likely to want to increase this buffer further.

The theory of buffer-stock saving was popularised by Christopher Carroll in 1992 (see link below). It implies that in the presence of uncertainty, people are prepared to consume less today in order to increase levels of saving, pay off existing debts, or borrow less relative to that in the absence of uncertainty. The extent of the buffer of financial wealth that people want to hold will depend on their own appetite for risk, the level of uncertainty, and the moderating effect from their own impatience and, hence, present bias for consuming today.

Risk aversion is consistent with the property of diminishing marginal utility of income or consumption. In other words, as people’s total spending volumes increase, their levels of utility or satisfaction increase but at an increasingly slower rate. It is this which explains why individuals are willing to engage with the financial system to reallocate their expected life-time earnings and have a smoother consumption profile than would otherwise be the case from their fluctuating incomes.

Yet diminishing marginal utility not only explains consumption smoothing, but also why people are willing to engage with the financial system to have financial buffers as self-insurance. It explains why people save more or borrow less today than suggested by our base-line consumption smoothing model. It is the result of people’s greater dislike (and loss of utility) from their financial affairs being worse than expected than their like (and additional utility) from them being better than expected. This tendency is only likely to increase the more uncertain times are. The result is that uncertainty tends to lower household consumption with perhaps ‘big-ticket items’, such as cars, furniture, and expensive electronic goods, being particularly sensitive to uncertainty.

Uncertainty and confidence

Uncertainty does not just affect risk; it also affects confidence. Risk and confidence are often considered together, not least because their effects in generating and transmitting shocks can be difficult to disentangle.

We can think of confidence as capturing our mood or sentiment, particularly with respect to future economic developments. Figure 3 plots the Uncertainty Index for the UK alongside the OECD’s composite consumer and business confidence indicators. Values above 100 for the confidence indicators indicate greater confidence about the future economic situation and near-term business environment, while values below 100 indicate pessimism towards the future economic and business environments.

Figure 3 suggests that the relationship between confidence and uncertainty is rather more complex than perhaps is generally understood (click here for a PowerPoint). Haddow, Hare, Hooley and Shakir (see link below) argue that the evidence tends to point to changes in uncertainty affecting confidence, but with less evidence that changes in confidence affect uncertainty.

To illustrate this, consider the global financial crisis of the late 2000s. The argument can be made that the heightened uncertainty about future prospects for households and businesses helped to erode their confidence in the future. The result was that people and businesses revised down their expectations of the future (pessimism). However, although people were more pessimistic about the future, this was more likely to have been the result of uncertainty rather than the cause of further uncertainty.

Conclusion

For economists and policymakers alike, indicators of uncertainty, such as the Ahir, Bloom and Furceri World Uncertainty Index, are invaluable tools in understanding and forecasting behaviour and the likely economic outcomes that follow. Some uncertainty is inevitable, but the persistence of greater uncertainty since the global financial crisis of the late 2000s compares quite starkly with the relatively lower and more stable levels of uncertainty seen from the mid-1990s up to the crisis. Hence the recent frequency and size of changes in uncertainty show how important it to understand how uncertainty effects transmit through economies.

Risk aversion in late-cycle slowing economies: the US experience

In recent months there has been growing uncertainty across the global economy as to whether the US economy was going to experience a ‘hard’ or ‘soft landing’ in the current business cycle – the repeated sequences of expansion and contraction in economic activity over time. Announcements of macroeconomic indicators have been keenly anticipated for signals about how quickly the US economy is slowing.

Such heightened uncertainty is a common feature of late-cycle slowing economies, but uncertainty now has been exacerbated because it has been a while since developed economies have experienced a business cycle like the current one. The 21st century has been characterised by low inflation, low interest rates and recessions caused by various types of crises – a stock market crisis (2001), a banking crisis (2008) and a global pandemic (2020). In contrast, the current cycle is a throwback to the 20th century. The high inflation and the ensuing increases in interest rates have produced a business cycle which echoes the 1970s. Therefore, few investors have experience of such economic conditions.

The focus for investors during this stage of the cycle is when the slowing economy will reach the minimum. They will also be concerned with the depth of the slowdown: will there still be some growth in income, albeit low; or will the trough be severe enough to produce a recession, and, if so, how deep? Given uncertainty around the length and magnitude of business cycles, this leads to greater risk aversion among investors. This affects reactions to announcements of leading and lagging macroeconomic indicators.

This blog examines what sort of economic conditions we should expect in a late-cycle economy. It analyses the impact this has had on investor behaviour and the ensuing dynamics observed in financial markets in the USA.

The Business Cycle


The business cycle refers to repeated sequences of expansion and contraction (or slowdown) in economic activity over time. Figure 1 illustrates a typical cycle. Typically, these sequences include four main stages. In each one there are different effects on consumer and business confidence:

  • Expansion: During this stage, the economy experiences growth in GDP, with incomes and consumption spending rising. Business and consumer confidence are high. Unemployment is falling.
  • Peak: This is the point at which the economy reaches its maximum output, but growth has ceased (or slowed). At this stage, inflationary pressures peak as the economy presses against potential output. This tends to result in tighter monetary policy (higher interest rates).
  • Slowdown: The higher interest rates raise the cost of borrowing and reduce consumption and investment spending. Consumption and incomes both slow or fall. (Figure 1 illustrates the severe case of falling GDP (negative growth) in this stage.) Unemployment starts rising.
  • Trough: This is the lowest point of the cycle, where economic activity bottoms out and the economy begins to recover. This can be associated with slow but still rising national income (a soft landing) or national income that has fallen (a hard landing, as shown in Figure 1).

While business cycles are common enough to enable such characterisation of their temporal pattern, their length and magnitude are variable and this produces great uncertainty, particularly when cycles approach peaks and troughs.

As an economy’s cycle approaches a trough, such as US economy’s over the past few months, uncertainty is exacerbated. The high interest rates used to tackle inflation will have increased borrowing costs for businesses and consumers. Access to credit may have become more restricted. Profit margins are reduced, especially for industrial sectors sensitive to the business cycle, reducing expected cash flows.

The combination of these factors can increase the risk of a recession, producing greater volatility in financial markets. This manifests itself in increased risk aversion among investors.

Utility theory suggests that, in general, investors will exhibit loss aversion. This means that they do not like bearing risk, fearing that the return from an investment may be less than expected. In such circumstances, investors need to be compensated for bearing risk. This is normally expressed in terms of expected financial return. To bear more risk, investors require higher levels of return as compensation.

As perceptions of risk change through the business cycle, so this will change the return investors will require from the financial instruments they hold. Perceived higher risk raises the return investors will require as compensation. Conversely, lower perceived risk decreases the return investors expect as compensation.

Investors’ expected rate of return is manifested in the discount rate that they use to value the anticipated cash flows from financial instruments in discounted cash flow (DCF) analysis. Equation 1 is the algebraic expression of the present-value discounted series of cash flows for financial instruments:

 
 
Where:
V = present value
C = anticipated cash flows in each of time periods 1, 2, 3, etc.
r = expected rate of return

For fixed-income debt securities, the cash flow is constant, while for equity securities (shares), expectations regarding cash flows can change.

Slowing economies and risk aversion

In a slowing economy, with great uncertainty about the scale and timing of the bottom of the cycle, investors become more risk averse about the prospects of firms. This this leads to higher risk premia for financial instruments sensitive to a slowdown in economic activity.

This translates into a higher expected return and higher discount rate used in the valuation of these instruments (r in equation 1). This produces decreases in perceived value, decreased demand and decreased prices for these financial instruments. This can be observed in the market dynamics for these instruments.

First, there may be a ‘flight to safety’. Investors attach a higher risk premium to risker financial instruments, such as equities, and seek a ‘safe-haven’ for their wealth. Therefore, we should observe a reorientation from more risky to less risky assets. Demand for equities falls, while demand for safer assets, such as government bonds and gold, rises.

There is some evidence for this behaviour as uncertainty about the US economic outlook has increased. Gold, long seen as a hedge against market decline, is at record highs. US Government bond prices have risen too.

To analyse whether this may be a flight to safety, I analysed the correlation between the daily US government bond price (5-year Treasury Bill) and share prices represented by the two more significant stock market indices in the USA: the S&P 500 and the Nasdaq Composite. I did this for two different time periods. Table 1 shows the results. Panel (a) shows the correlation coefficients for the period between 1 May 2024 and 31 July 2024; Panel (b) shows the correlation coefficients for the period between 1 August 2024 and 9 September 2024.

In the period between May and July 2024, the 5-year Treasury Bill and share price indices had significantly positive correlations. When share prices rose, the Treasury Bill’s price rose; when share prices fell, the bill’s price fell. During that period, expectations about falling interest rates dominated valuations and that effected the valuations of all financial instruments in the same way – lower expected interest rates reduce the opportunity cost of holding instruments and reduces the expected rates of return. Hence, the discount rate applied to cash flows is reduced, and present value rises. The opposite happens when macroeconomic indicators suggest that interest rates will stay high (ceteris paribus).

As the summer proceeded, worries about a ‘hard landing’ began to concern investors. A weak jobs report in early August particularly exercised markets, producing a ‘flight to safety’. Greater risk aversion among investors meant that they expect a higher return from equities. This reduced perceived value, reducing demand and price (ceteris paribus). To insulate themselves from higher risk, investors bought safer assets, like government bonds, thereby pushing up their prices. This behaviour was consistent with the significant negative correlation observed between US government debt prices and the S&P 500 and Nasdaq indices in Panel (b).

Another signal of increased risk aversion among investors is ‘sector rotation’ in their equity portfolios. Increased risk aversion among investors will lead them to divest from ‘cyclical’ companies. Such companies are in industrial sectors which are more sensitive to the changing economic conditions across the business cycle – consumer discretionary and communication services sectors, for example. To reduce their exposure to risk, investors will switch to ‘defensive’ sectors – those less sensitive to the business cycle. Examples include consumer staples and utility sectors.

Cyclical sectors will suffer a greater adverse impact on their cash flows and risk in a slowing economy. Consequently, investors expect higher return as compensation. This reduces the value of those shares. Demand for them falls, depressing their price. In contrast, defensive sectors will be valued more. They will see an increase in demand and price. This sector rotation seems to have happened in August (2024). Figure 2 shows the percentage change between 1 August and 9 September 2024 in the S&P 500 index and four sector indices, comprising companies from the communication services, consumer discretionary, consumer staples and utilities sectors.


Overall, the S&P 500 index was slightly higher, as shown by the first bar in the chart. However, while the cyclical sectors experienced decreases in their share prices, particularly communication services, the defensive companies experienced large price increases – nearly 3% for utilities and over 6% for consumer staples.

Conclusion

Economies experience repeated sequences of expansion and contraction in economic activity over time. At the moment, the US economy is approaching the end of its current slowing phase. Increased uncertainty is a common feature of late-cycle economies and this manifests itself in heightened risk aversion among investors. This produces certain dynamics which have been observable in US debt and equity markets. This includes a ‘flight to safety’, with investors divesting risky financial instruments in favour of safer ones, such as US government debt securities and gold. Also, investors have been reorientating their equity portfolios away from cyclicals and towards defensive securities.
