When the UK’s first estimate of quarterly growth comes out, most headlines focus on the overall number. Economists, though, often jump straight to one line further down: business investment. It is one of the clearest signs of whether companies feel confident about the future, and it can say more about the economy’s direction than the headline figure.
What business investment means
Business investment is the money companies spend on assets they expect to use for more than a year. That includes machinery, vehicles, computers, software, buildings and research and development. It does not include spending on day-to-day costs such as wages or raw materials. In official statistics it forms part of a wider category called gross fixed capital formation, which also includes government and household investment such as new homes.
The Office for National Statistics publishes a first estimate alongside the preliminary GDP figures each quarter, with more detail and revisions later. Our guide to capital expenditure explains the same idea from a single company’s point of view.
Why it matters for the economy
Investment is how an economy grows its capacity to produce. New machines, better software and modern buildings help workers produce more each hour, which supports wages and living standards over time. A country that invests little tends to struggle with productivity, which has been a long-running concern in the UK.
In the short term, business investment is also a confidence indicator. Companies invest when they expect demand to hold up and when they feel reasonably sure about costs, regulation and politics. When uncertainty rises, investment is often one of the first things to be delayed.
Why the numbers can be noisy
Business investment is one of the most volatile parts of GDP. A few large purchases, such as aircraft or big construction projects, can swing a quarter’s figure sharply. The first estimate is also based on incomplete information and is frequently revised, sometimes by a lot. That means a single quarter’s jump or fall should be treated with care.
Economists often look at the trend over several quarters, or compare investment to its level a year earlier, to get a clearer picture. Our explainer on quarter-on-quarter versus year-on-year growth covers the difference.
How markets react
Business investment rarely moves markets on its own the way inflation data can. But it shapes the story behind the headline growth number. If GDP growth is strong because of government spending or a build-up of stock, while business investment is falling, economists may see the growth as less durable. If investment is rising, it suggests companies expect demand to continue, which can support the case for higher interest rates when inflation is a concern.
For sterling and gilts, the effect depends on what the Bank of England is focused on. When the Bank is worried about inflation, signs of strong demand, including healthy investment, can support expectations of tighter policy. When growth is the worry, weak investment adds to the case for caution.
What to look for on release day
On GDP day, check whether investment rose or fell on the quarter, how the figure compares with a year earlier, and whether the previous quarter was revised. Then see how it fits with the rest of the expenditure breakdown, covered in our guide to the expenditure breakdown of UK GDP. Business surveys, such as purchasing managers’ indices, can help confirm whether the trend is real.
The bottom line
Business investment is a window into how confident companies are about the future. It is noisy and often revised, but over time it tells you a lot about where the economy is heading. Reading it alongside the headline growth figure gives you a fuller picture. If you want to understand how you interpret mixed economic signals, take the free Samuel & Co Trading trader assessment.
