Many of our clients at Lazenby Financial Services follow the financial news closely. When the FTSE 100 hits a new high – or takes a tumble – they often ask me what this means for the UK economy and, more importantly, for their own pensions and investments.
It’s a natural question, but there’s a common misconception here. The FTSE 100 is not a reliable barometer of the health of the UK economy. Here’s why.
What is the FTSE 100?
The FTSE 100 is simply an index of the 100 largest companies listed on the London Stock Exchange, ranked by market capitalisation. While these are UK-listed firms, many are truly global businesses.
Global Revenues, Not Domestic Performance
Over four-fifths of the sales of FTSE 100 companies now come from outside the UK. Giants such as Shell, HSBC, AstraZeneca, and Unilever generate the majority of their revenues and profits from international markets – often in US dollars or other currencies. This means the index is heavily influenced by global economic conditions, commodity prices, exchange rates, and overseas demand rather than what’s happening on UK high streets or in British factories.
When the pound weakens, for example, overseas earnings convert into more sterling, boosting the index even if the UK economy is facing challenges.
Sector Bias
The index is also heavily weighted towards certain sectors: financial services, oil & gas, mining, and pharmaceuticals. These are important industries, but they don’t represent the full picture of the UK economy. Services make up around 80% of UK GDP, including retail, hospitality, education, and healthcare – areas where smaller companies and domestic-focused businesses dominate.
A Better Reflection of the UK Economy
For a clearer view of domestic economic health, many analysts look to the FTSE 250. This index includes the next 250 largest companies, which tend to have far more exposure to the UK market. Indicators like GDP growth, employment figures, consumer spending, and business investment tell a more complete story about how the UK as a whole is performing.
What is the FTSE 250?
The FTSE 250 tracks the next 250 largest companies listed on the London Stock Exchange after the FTSE 100. These are typically mid-cap businesses with market capitalisations ranging from around £500 million up to several billion. While still significant, they are generally smaller and more varied than the blue-chip giants in the FTSE 100.Domestic Focus vs Global Reach
The key difference lies in where these companies earn their money. Recent data shows that around 43% of FTSE 250 revenues come from the UK domestic market – a much higher proportion than the FTSE 100, where overseas earnings often exceed 70-75%.
What This Means for You
Understanding this distinction is important for your financial planning. A rising FTSE 100 can provide good returns for globally diversified portfolios – which is often beneficial. However, it doesn’t necessarily signal that the UK economy is booming, just as a weak FTSE doesn’t always mean trouble for British businesses and jobs.
