The UK economy grew. Why does it not feel like it?

The number looks good. The reality does not.

The number looks good. It seems simple. The UK economy grew in July. That is the official news. The Office for National Statistics released its monthly estimate showing a 0.4 per cent increase in gross domestic product. This was unexpected. It beat forecasts. It was an improvement on the 0.3 per cent growth recorded for June, a small but positive acceleration that suggests some part of the country’s economic engine is firing. This single digit offers a sliver of welcome news for a new chancellor, John Healey, just weeks before he delivers his first budget. It is only a sliver.

For most people, this will not feel like a recovery. It will not feel like growth. The figure from the ONS is an abstract calculation, a statistic smoothed and seasonally adjusted, a single point of data in a sea of difficult economic currents. Your own bank balance is not an abstract. The cost of the weekly shop is not a statistical estimate. The real economy, the one experienced by millions of households and businesses every single day, is defined by much harder realities. These realities are getting worse. Two pressures are building that a single month of GDP growth cannot fix. They are inflation and the cost of borrowing.

The risk of rising prices has not gone away. Far from it. Anxieties about inflation are mounting again, threatening to erode any small gains in wages or economic activity with higher costs for food, for fuel and for the basic goods that keep a household running. At the same time, the price of money itself is increasing. Borrowing costs are climbing. This means more expensive mortgages for homeowners, higher interest payments on business loans and steeper charges for anyone using credit to make ends meet. They are here now. They are squeezing budgets. This is the context for July’s surprise growth, a context of immense financial pressure that makes a 0.4 per cent rise feel less like a turning point and more like a statistical anomaly before the next storm arrives.

AI is doing the heavy lifting.

So where did the growth come from. It was not broad. The headline number was not driven by a national rebound in manufacturing, a revival on the high street or a surge in house building. The source is narrow. The underlying detail, supported by early analysis, points to one sector doing almost all of the work to generate that 0.4 per cent figure. This is artificial intelligence.

The boom is real. It is also highly specific. AI investment means huge, discrete blocks of capital spending, not the small, distributed transactions that characterise a healthy consumer economy. Think of data centres. These are vast industrial buildings, often windowless and anonymous, being constructed on sites with access to the national grid and fibre optic cables. These projects require enormous upfront investment in land, in materials and in specialist construction, all of which registers as a positive contribution to GDP. They are not, however, big employers once they are built, and the economic benefit is often concentrated in the hands of the developers and the technology firms that will eventually fill them with servers. This is one part of the AI story.

The other part is less visible. It is the purchase of hardware and software. The growth in July was powered by companies spending millions of pounds on the complex computing equipment needed to train and run artificial intelligence models. This means huge orders for specialist graphics processing units, the microchips that are the essential engine of AI, from a very small number of global manufacturers. It also involves signing multimillion pound, multi year contracts for cloud computing services and enterprise software licences. This is big money. It moves between the balance sheets of very large corporations. It all counts towards national output.

This is why the growth feels so distant. It is a narrow boom. The activity is happening inside specific technology companies, or on particular industrial estates, or within the accounts of a few large firms making strategic investments. This is not the kind of distributed economic activity that lifts high streets in Doncaster or fills order books for small manufacturers in Dudley, but a concentrated surge of spending by large corporations on highly specialised technology. It is a world away from the pressures on a family budget. The profits flow to a select group of global firms and their shareholders. The GDP figure gets a temporary boost. The wider economy feels very little of it.

This is just one month of data.

This is just one number. It represents one month. The Office for National Statistics reports that the United Kingdom's economy grew by 0.4% in July. But this figure is a first guess, an initial sketch drawn from incomplete data that will be redrawn again and again over the coming months. These provisional figures are always subject to revision. They are famously volatile. An economy that appears to be growing can, with the benefit of more complete data, be shown to have been shrinking all along. The opposite can also be true. A feared recession can simply vanish from the historical record after a series of statistical updates. This process is not a failure. It is the reality of trying to measure a £2.8 trillion economy in real time. It is statistics.

The July growth of 0.4% followed a 0.3% rise in June. Two months of positive figures. That sounds like acceleration. In reality, the difference is just 0.1 of a percentage point, a margin so small it could easily be statistical noise, a ghost in the machine of data collection. This is why economists rarely get excited by a single monthly release. They prefer to examine three month rolling averages which smooth out the sawtooth pattern of monthly data, or they wait for the more robust quarterly figures which give a much clearer picture of the underlying trend. One month does not make a recovery. Two months of anaemic growth are not proof that the economy has found a new, higher gear, particularly when the pressures of high borrowing costs and looming inflation remain the dominant reality for most businesses and households. This is not a trend. It is a data point.

A single number can be misleading. It can be dangerous. It provides a simple headline that masks a complex and uncertain reality, offering ammunition for politicians to declare a corner has been turned. The chancellor, John Healey, will welcome the news as he prepares his autumn budget. His opponents will claim it is a temporary blip. The truth is that nobody knows for sure. What happens in August, September and October will provide the real answer. It is in those months that the full impact of the energy squeeze will be felt and the consequences of the Iran war fallout may become clearer. A genuine economic recovery is broad and durable. It is not a fragile, narrowly based, and provisional figure that could be revised away by Christmas.

Two threats are getting closer.

This growth is fragile. It is provisional. Two large threats are getting closer, both with the power to push any recovery off course long before it is felt by households. One is war. The other is energy. They are linked.

The first threat begins thousands of miles away. It begins in Iran. War in the Persian Gulf is not a distant problem for Britain, because the UK economy runs on the global supply of energy and goods that flows through the region. A conflict involving Iran directly threatens the Strait of Hormuz, the narrow waterway through which a fifth of the world’s oil passes every day. This is the chokepoint. Any disruption, real or anticipated, sends insurance premiums for tankers soaring and adds a risk premium to the price of every barrel of crude oil. The effect is immediate. It travels from the trading floors in London and New York to the forecourts of every petrol station in the United Kingdom. It is a direct transmission mechanism for inflation. Higher fuel costs for haulage firms on the A1(M) mean higher prices for the goods they carry to the supermarkets. War is expensive for everyone.

The second threat is the energy squeeze. This is closer to home. Its arrival is certain. While July’s economic activity was being measured, wholesale gas prices were already rising on European markets. The mechanism for this pain is slow, but it is relentless. Britain’s energy regulator, Ofgem, adjusts its price cap based on these wholesale costs, but with a delay. This means the high prices paid by energy suppliers over the summer will translate directly into sharply higher bills for households and businesses this autumn. This is the squeeze. A business owner in Birmingham who saw steady trade in July will see their electricity bill spike in October. A family in Glasgow will have to find hundreds more pounds just as the heating is switched on for winter. It is an economic shock that has not happened yet. It is already baked in.

The growth is not for everyone.

This growth is not a national story. It is a story about technology. Specifically, artificial intelligence. The 0.4% rise in GDP is happening inside data centres and on the balance sheets of a few specialised firms. It is not on the high street. The winners are clear. They are the companies making large capital investments in AI, the investors funding this new gold rush, and the highly skilled software engineers designing the systems. This prosperity is real. It is also narrow. It is concentrated in the gleaming office parks of the Thames Valley or the server farms being built on the outskirts of London. It is a wealth of algorithms and silicon. This does not look like a recovery to most people because it does not employ most people or happen where most people live.

The losers feel no part of this. Their reality is shaped by different numbers. Not 0.4% growth. But the prospect of sharply higher energy bills. For them, the economy is not a graph pointing upwards. It is a tightening squeeze. The losers are energy intensive businesses, the factories in the Midlands and the chemical plants in the North East, whose costs are about to become unmanageable. They are small hospitality businesses. The pub landlord in Bolton. The cafe owner in Belfast. Their thin profit margins will be erased by soaring electricity prices and customers with less money to spend. They are the households on fixed incomes. Low wages. Tight budgets. For a family in a poorly insulated terrace house in Stoke on Trent, a small increase in the wholesale price of gas translates into a brutal choice in January between heating and eating.

There are two economies in Britain now. They exist side by side. They do not mix. One is a digital economy of AI investment, a sector experiencing a miniature boom and generating statistical growth for the nation. It is small. It is exclusive. The other is the physical economy, the one of manufacturing and services, the economy where households spend and the vast majority of the population works. This second economy is facing a severe contractionary shock from war driven inflation and the looming energy price crisis. The headline GDP figure is a statistical average of these two opposing forces. It is an illusion of stability. The lift from the AI sector is just enough, for now, to mask the immense strain being placed on the foundations of the wider economy. It is a single bright light in a darkening room. One sector cannot carry a country.

This is the chancellor's new problem.

This number is a problem for John Healey. It is a trap. The 0.4% growth figure for July, delivered by the Office for National Statistics, has created a dangerous political mirage for the new chancellor. On the surface it is welcome news. Very welcome news. It gives the impression of economic strength just as Healey prepares his first budget. The reality is that this single, AI driven data point has handed his opponents, and indeed his own allies, a weapon to use against him, forcing him towards a decision that could define his entire term at the Treasury. He cannot win.

The pressure will be immense. The calls will come from everywhere. From his own backbenches, where MPs will see the 0.4% figure as a green light for investment in their constituencies. From public sector unions, who will brandish the statistic as justification for the pay rises they believe are long overdue after years of restraint. Every spending department in Whitehall will now be redrafting their submissions to the Treasury, arguing that the time for caution is over and the moment for ambitious, expansive programmes has arrived. They will tell him the economy is growing. They will say Britain can afford it. They will say this is what a Labour government was elected to do. The number gives them all permission to ask for more.

Healey knows the truth. His advisers at One Horse Guards Road will be presenting him with a far bleaker set of spreadsheets. They will brief him not on July's AI boom but on the coming winter squeeze. They know the fallout from the Iran war is a real and present danger to British supply chains. They see the storm gathering over energy markets. They understand that a tech boom concentrated in one small part of the economy does not provide the tax receipts needed to fund a nationwide spending spree, especially when inflation risks remain so high. To inject billions of new spending into an economy already straining under the threat of soaring energy costs would be an act of profound fiscal recklessness. It risks stoking the very inflation he needs to control.

So the chancellor is caught. He is trapped between political expectation and economic reality. He can deliver a budget for his party, spending the proceeds of a recovery that does not yet exist and risking a damaging collision with financial markets over the UK’s borrowing costs. Or he can deliver a budget for the bond markets, imposing a painful fiscal discipline that acknowledges the fragility of the economy, and in doing so invite the fury of his colleagues and the disappointment of the country. He has one month. He must choose a path. One risks economic ruin. The other invites political rebellion. This is the chancellor’s problem now.
