Relationship between stock market and economy

Readers Question: What’s the relationship between a countries economy and it’s stock market? Is it always true that the stock market reflects a country’s economic conditions?

Generally speaking, the stock market will reflect the economic conditions of an economy. If an economy is growing then output will be increasing and most firms should be experiencing increased profitability. This higher profit makes the company shares more attractive – because they can give bigger dividends to shareholders. A long period of economic growth will tend to benefit shares.

By contrast, if the stock market predicts a recession, then share prices will generally fall – in anticipation of lower profits.

If the economy is forecast to enter into a recession, then stock markets will generally fall. This is because a recession means lower profits, fewer dividends and even the prospect of firms going bankrupt, which would be bad news for shareholders.

Also, in a period of uncertainty, investors may prefer to buy bonds for the greater security and avoid shares, because of the greater risk involved.

Do falling share prices indicate a recession?

However, share prices can fall for many reasons other than recession. An oft-repeated quote is that ‘stock markets have predicted ten of the past five recessions.’ What this means is that sometimes a fall in share prices is related to a recession. But, sometimes share prices fall and there is no correlation with the economy. It could be a correction of over-valued prices or a change in market sentiment.

1987 Stock market crash

In October 1987, stock markets around the world fell 25%. Many feared this predicted a major global recession. In response policymakers cut interest rates. But, the stock market crash appeared to have no bearing on the economy. The late 1980s were a boom time in many western economies. Even now, investors are not entirely sure why share prices fell 25%. Some blame ‘technical factors.’

2018 decline

Towards the back end of 2018, stock markets have been falling. Many fear this signals the possibility of a recession but it is too early to say definitely whether there is a recession around the corner.

Why can stock markets rise in a recession?

In a recession or period of uncertainty, stock markets can sometimes increase, why is this?

Anticipation effects. Stock markets are forward-looking. The stock market may already have priced in the effect of the recession and now the stock market is anticipating a recovery. For example, stock markets in 2007 and 2008 performed badly in anticipation of a US recession. But, during a long period of economic stagnation, stock markets might do better than expected because they are recovering former losses.

Profits as a share of GDP. Since the 2008 credit crunch, we have seen company profit become a bigger share of national income. Despite low economic growth, firms have been able to increase profitability. In short, real wage growth has been muted, but many companies have seen a rise in profits and cash reserves. This is due to factors, such as the monopoly power of large IT firms, such as Apple, Google and Microsoft. Therefore, despite relatively weak economic growth, publically listed companies, are still attractive to shareholders because they have retained their profitability, and even increased it faster than GDP growth.

Ultra-low interest rates. In 2016, there was a rise in government bonds with negative yields. This means investors were buying bonds – even though, they lose money because of negative interest rates. This is because, in that  climate, investors were pessimistic about the fortunes of the economy. With great uncertainty in the economy, investors are happy to buy bonds for the security they offer – even though they have very poor returns. Because of ultra-low interest rates, shares became relatively more attractive. Investors are willing to buy shares, despite the threat of recession, because they at least have a good yield compared to bonds.

Ironically, the stock market can do relatively well because there is a poor choice of investment opportunities.

Selective share prices

It is also worth noting that within the stock market, different firms and sectors will be more affected by bad economic news. For example, after Brexit June 2016, we see a fall in share price for sectors, such as construction and banks. These sectors are more affected by an economic downturn. In a downturn, with falling house prices, we will see a big fall in demand for building new houses and also demand for luxury items. Banks may lose out because of the decline in profitability and demand for loans.

However, other sectors may prove more robust. For example, food and drink are less likely to be affected by a recession. Even in times of negative growth, people will still want to buy food and drink.

FTSE-100 vs FTSE-250


FTSE-100 since 1985. FTSE-100 fell 2000 to 2004 – despite good economic growth and low inflation.

After the Brexit vote, the FTSE-100 has done much better than the FTSE-250. This is because the FTSE-100 is mainly comprised of multinational firms, whose profitability is dependent on strength of US and global economy; they are less reliant on UK economy and the value of the Pound. However, the FTSE-250 is composed of smaller companies who are more dependent on UK economy, and so are more influenced by prospects of a UK recession.

Stock markets and developing economies

If you have a country with a consistently higher rate of economic growth, then generally stock markets will perform better than in a country with lower rates of growth. The link may not be perfect but there is definitely some correlation.

When the stock market can affect the economy

In some situations, you can argue that the stock market can actually affect the economy. The best case is the Wall Street Crash of 1929-32. This rapid decline in the stock markets severely affected business and consumer confidence. It also caused banks to lose money. This crash was undoubtedly a factor in contributing to the length and severity of the Great Depression. Having said that, it is also worth pointing out that the stock market crash was due to the prospect of recession. In a way, the falling stock market and depression were closely linked.

The stock market doesn’t always affect the economy. On Black Monday 1987 stock markets around the world crashed. However, this didn’t precipitate a recession like previous stock market crashes.
