The number that stunned the City
The number stunned the City. It was 0.4 per cent. This was the UK economy’s official expansion for July, published on Friday morning by the Office for National Statistics. It was not meant to be like this. The predictions had been uniform, with economists forecasting a month of absolute stagnation, a period where the economy did not grow at all. The consensus was zero. Instead, the data showed an economy picking up speed, creating a gulf between expert expectation and lived reality that left many analysts scrambling to understand what they had missed. This was not a minor deviation. This was a different story entirely.
Gross Domestic Product is a clumsy term. Think of it as the economy’s vital sign. It is the pound value of everything the country makes and sells over a period, a colossal calculation that encompasses every transaction from a software contract signed in Manchester to a haircut in a Brighton salon. A positive figure means the economy is getting bigger. A negative one means it is shrinking. The monthly GDP release from the ONS, therefore, is the most regular and most watched national health check, a single digit that has the power to shift financial markets and alter the calculations on Threadneedle Street. It is the pulse of the nation measured in spreadsheets.
This single figure changed the narrative. The surprise was genuine. An economy widely expected to flatline had instead accelerated, even improving on the 0.3 per cent growth recorded for the previous month of June. For traders and investors watching their screens in London, the result demanded a rapid reappraisal of Britain’s immediate economic prospects. The forecasts were wrong. The economy grew. The immediate question became a simple one. Why.
It was not the prime minister
Some have already claimed victory for the new occupant of Number 10. The new prime minister, Andy Burnham, was credited by at least one City newspaper with engineering July’s surprise growth. The logic is seductively simple. He took office. The economy grew. It is a tempting narrative for a new administration keen to demonstrate immediate impact and a clean break from the past. It is also completely wrong. The British economy is not a speedboat that can be turned on a five pence piece by a new hand at the tiller, it is an oil tanker whose course is set months, even years, in advance. To suggest a prime minister can reshape economic outcomes within their first few weeks in Downing Street is a fundamental misunderstanding of how the country is governed and how a £2.5 trillion economy actually functions.
Economic policy is slow. It grinds. Consider a new government's first budget, its primary tool for influencing the economy through tax and spending. This single event takes months to formulate, requiring detailed analysis from the Treasury, independent forecasts from the Office for Budget Responsibility, and intense political negotiation before it is ever announced in the House of Commons. After that, its measures must be legislated for, another slow process involving committees and votes. Only then do changes like a cut to National Insurance or an alteration in corporation tax begin to affect household budgets and company investment decisions. The entire cycle, from idea to impact, can take the better part of a year. Major infrastructure projects or regulatory reforms, from planning laws to financial services rules, operate on even longer timescales, often taking an entire parliament to move from white paper to reality.
A new prime minister inherits an economy. They do not create one overnight. The momentum in the system, positive or negative, is a legacy of their predecessor, the global economic climate, and the prior decisions of the Bank of England. The 0.4 per cent growth recorded for July, following on from 0.3 per cent growth in June, was baked in long before Mr Burnham arrived in Downing Street. It was the result of millions of individual spending and investment choices made by households and businesses reacting to conditions that were already in place. Political opportunism loves to claim these numbers. Economic reality is different. The truth is far more complex, and much, much slower.
So what really drove the growth?
The boost did not come from factories or building sites. It came from services. The Office for National Statistics reported that this vast part of the British economy grew by 0.4 per cent in July. This was the source of the surprise. Understanding the services sector is key to understanding the entire UK economy, because in modern Britain they are almost the same thing. It is everything that does not involve making a physical object or growing something from the ground. It is the insurance policy sold in the City of London, the haircut in a local salon, the legal advice from a solicitor, and the software designed in a Manchester office.
Services account for four fifths of Britain’s entire economic output. Its health is the nation's health. When this part of the economy expands, it pulls the headline number for Gross Domestic Product up with it. The sector is a sprawling collection of different industries, from the drivers delivering parcels bought online to the bankers structuring billion pound corporate deals. A single monthly figure, like the one for July, aggregates all this activity, hiding the individual details of which parts are booming and which are struggling. The ONS has not yet published that granular detail. That has not stopped analysts from searching for clues.
They are looking for temporary factors. They always do. Monthly data can be noisy, thrown off course by events that have little to do with the underlying health of the economy. Unusually warm and sunny weather across July, for example, could easily have prompted a temporary rise in consumer spending as people filled pub gardens, flocked to seaside resorts, and spent more on leisure activities. This is a real increase in economic activity. It is just not one that can be relied upon to repeat itself in a wet and windy August, meaning it flatters the numbers for one month without signalling a genuine, sustainable recovery.
Other one off events could also be responsible. A huge international sporting event or a major concert tour by a global artist can have a measurable impact, funnelling money into hotels, restaurants, and transport in host cities for a few short weeks. Equally, a strong month for the financial sector, where a handful of large merger and acquisition deals happen to complete, can create a spike in the numbers that is not reflected in the wider experience of most businesses. The critical task is to separate these fleeting boosts from a real change in direction. The question is not whether the economy grew. The question is why. The answer will determine whether this is the start of a recovery, or just a statistical mirage.
A headache for Threadneedle Street
Good news can be a headache. This particular piece of good news creates a very large one for the Bank of England. The nine economists and officials on its Monetary Policy Committee are now staring at a much harder decision than they were a day ago, all because the economy did something nobody expected it to. Their job just became more complicated.
The fundamental problem is inflation. The Bank's single most important task is to keep inflation at its two per cent target. When the economy grows faster than predicted, it means more money is being spent, more demand is chasing a finite supply of goods, and more people are in work earning wages they are eager to use. This all creates upward pressure on prices, making inflation stickier and harder to bring down from the elevated levels the country has endured. This is the very activity the Bank has been trying to cool for the past two years.
Its main weapon is the base interest rate. By raising it, the Bank makes borrowing more expensive across the entire economy. This is not an abstract concept. It has a direct, and often painful, impact on millions of people through higher mortgage payments and more costly loans for cars or home improvements. It also squeezes businesses, making it more expensive for them to borrow money to expand, hire staff, or invest in new equipment. The Bank has already raised rates multiple times, deliberately trying to slow the economy down just enough to get prices under control without causing a deep recession. July’s growth figure suggests that policy is not working as effectively as the committee might have hoped.
This puts the Bank in a trap. A difficult choice. The path ahead is now much less clear. If the Monetary Policy Committee responds to this stronger growth by raising rates again, or keeping them higher for longer, it will increase the financial pain for households and companies, raising the risk of tipping the economy into the recession it has so far narrowly avoided. If it chooses to hold off, waiting for more data, it risks being seen to go soft on inflation, allowing prices to continue eroding the value of people's savings and wages. Either choice carries a heavy price. This one surprising number, 0.4 per cent, has made a difficult balancing act almost impossible.
Look at the quarter, not the month
A single month is not a trend. It is a snapshot. A flicker. The shock 0.4 per cent growth figure for July is just one data point in a very long series, and reading too much into it is a classic forecasting error. These initial estimates from the Office for National Statistics are always provisional. They are a first guess, assembled quickly to give an early indication of economic activity, but they are frequently changed. The ONS constantly receives more detailed information from businesses and public bodies, leading to revisions, sometimes significant ones, in the months that follow. The July number we see today might not be the final July number at all. Data gets revised.
This is why economists and analysts prefer a different measure. They look at the rolling three month average. This approach smooths out the statistical noise and monthly volatility that can be caused by anything from a major sporting event to the timing of a bank holiday. It gives a far more stable and reliable picture of the true health and direction of the economy. Think of it like this. One month’s data is a single still photograph, which can be misleading, while the three month view is a short piece of film, revealing the actual motion. It tells you whether the economy is genuinely accelerating, just holding steady, or beginning to slow down towards a stall. That context is everything. The real story is rarely found in a single, noisy number.
The verdict on July’s surprise performance is therefore still pending. It awaits more evidence. The question of whether this growth was a temporary blip or the beginning of a sustained recovery will only be answered when the data for August and September are released. Those figures will complete the picture for the third quarter of the year. If August’s GDP also comes in strong, it will suggest a genuine change in momentum may be underway. If it slumps back to zero or turns negative, it will make July look like a statistical fluke, an outlier with little meaning for the bigger picture. The numbers to watch for are the next ones. They will provide the real test.
The recovery is still fragile
July was a good month. It was one good month. One surprising datapoint does not reverse a long term trend, and it is the long term trend that dictates the country’s prosperity compared to its international competitors. The UK is a member of the G7 group of large, advanced economies. This is the real league table.
Here, the picture is much less encouraging. For years, Britain’s economic growth has struggled to keep pace with that of its peers, frequently bumping along at the bottom of the G7 performance tables alongside countries like Germany or France while the United States economy pulls further ahead. This is not a new story. It is a persistent problem. A sustained period of stronger growth, not a single month’s positive reading, is required to begin closing that gap and altering the UK’s trajectory on the world stage. The climb is steep.
The reasons for this sluggishness are deep and structural. They are the problems that prime ministers and chancellors talk about but have consistently failed to fix. At the heart of the issue are two related failings, low productivity and chronically weak business investment. Productivity, which is simply a measure of the economic output generated for every hour worked, has stagnated for more than a decade, meaning the country is not getting significantly better at making things or delivering services efficiently. This is linked directly to the second problem, because companies that do not invest in new machinery, better software and modern facilities will inevitably fall behind their international rivals who do. The engine is not firing properly.
A single month of growth, driven largely by consumer spending in the services sector, does nothing to address these fundamental weaknesses. It is welcome news for households and for the government, but a person feeling well enough to go out for a meal does not mean they have solved an underlying chronic health condition. The economy’s foundations are what truly matter. Those foundations are still weak. The hard work has not been done. This surprise number, while cheering, changes very little about the difficult path that lies ahead for the British economy. A real recovery will take years, not a month.
