Services drove the 0.6% Q1 expansion. Revisions and Iran war pressures point to a consumer-led slowdown in Q2. Wholesale, tech, and advertising led; retail and leisure face the squeeze.
Alpha Score of 26 reflects poor overall profile with poor momentum, poor value, moderate quality, weak sentiment.
The UK economy expanded 0.6% in the first quarter, the Office for National Statistics reported, with the services sector driving the gain. Wholesale trade, computer programming, and advertising all posted strong performance. Construction also returned to growth. The monthly figure for March came in at 0.3%, stronger than expected for the first full month since the Iran war erupted.
Traders scanning the stock market analysis for a simple growth read will see a headline beat and a Chancellor claiming vindication. The better market read is more fractured. Revisions shaved 0.1 percentage point off both January and February, leaving the quarterly number dependent on a single month that already looks stale. Forward-looking warnings from KPMG and Aberdeen Investments point to a consumer squeeze, higher energy costs, and political uncertainty that will hit the second quarter harder. The GDP print is a rear-view mirror. The trade is in which sectors absorb the coming shock and which ones already priced it.
The ONS singled out wholesale trade, computer programming, and advertising as the standout performers within services. That narrows the read-through for equity traders. UK-listed wholesalers, IT services firms, and advertising agencies are the direct beneficiaries of the Q1 momentum. The mechanism is straightforward: business spending on digital transformation and marketing held up even as consumer confidence wobbled.
Wholesale strength can signal two very different things. It can reflect genuine end-demand from retailers and manufacturers. It can also reflect precautionary inventory building ahead of expected supply disruptions. The Iran war began in late March, so the Q1 data captures only a few days of conflict. Wholesale volumes that rose on restocking may reverse if downstream demand weakens. Traders should watch for inventory-to-sales ratios in coming ONS releases. A build without a corresponding retail sales uptick would be a red flag for wholesalers.
IT services and computer programming are less exposed to the immediate energy shock. Digital transformation projects have multi-quarter timelines and are harder to cancel on a dime. The Q1 strength here aligns with a longer-term trend of UK businesses investing in automation and cloud migration. Companies with recurring revenue from managed services or long-duration contracts are better positioned than those reliant on discretionary project work. The read-through favours IT consultancies and software firms over hardware resellers.
Advertising is among the most cyclical sub-sectors. The Q1 strength suggests marketing budgets were still being deployed. If consumer spending contracts in Q2, advertising is typically one of the first line items to be cut. The ONS data does not distinguish between digital and traditional advertising. The broader shift to performance-based digital spend may provide some insulation. Pure-play agencies with high exposure to brand advertising face a tougher second half.
Construction output grew in Q1, partially reversing the weakness seen at the end of last year. Liz McKeown, ONS director of economic statistics, noted the sector "only partly reversing weakness at the end of last year." The recovery is fragile. Housebuilders and commercial construction firms may see a temporary lift. Higher borrowing costs and political uncertainty around fiscal policy are headwinds.
Shadow chancellor Mel Stride pointed to borrowing costs hitting their highest level in 30 years this week. That raises the cost of mortgages and project finance. Construction firms with exposure to residential development face a double hit: weaker demand from affordability-stretched buyers and higher financing costs for land and materials. Infrastructure and public-sector construction may hold up better if government spending plans remain intact. The political noise around fiscal policy makes that uncertain.
Yael Selfin, KPMG's chief economist, delivered the most concrete warning. She said the impact of the Iran war would be "more pronounced in the second quarter." Households face renewed pressure from climbing energy and petrol prices. Food costs are expected to rise, with disruptions to fertilisers and other essential inputs. The transmission mechanism is direct: higher input costs compress margins for consumer-facing businesses, while higher household bills reduce discretionary spending.
The sectors most exposed to this squeeze are retail, leisure, hospitality, and consumer durables. These are the areas where traders should model a demand shock. The Q1 GDP data will not reflect this; the March monthly figure captures only the very start of the conflict. Second-quarter retail sales data, due in late May, will be the first hard evidence of consumer behaviour under the new energy price regime.
Selfin specifically flagged fertiliser disruptions. That points to agricultural input costs and, downstream, food producers and supermarkets. UK-listed food retailers may face margin compression if they cannot pass through higher costs. Discount retailers could gain market share as consumers trade down. The read-through is not uniform: it favours value-oriented retailers over premium grocers.
Luke Bartholomew, deputy chief economist at Aberdeen Investments, said the growth figures would not matter much to markets "given how things have moved on since then." He highlighted two forward-looking risks: higher energy prices stunting recovery, and political uncertainty weighing on investment due to "the possibility of a significant change in fiscal policy."
The shadow chancellor's reference to 30-year high borrowing costs is not just political rhetoric. It reflects a real repricing of UK sovereign risk. If fiscal policy shifts toward higher spending and borrowing, gilt yields could rise further, tightening financial conditions for the whole economy. That would hit rate-sensitive sectors: real estate, utilities, and high-yield credit. Traders should monitor the spread between UK gilts and German bunds as a real-time gauge of fiscal risk perception.
Bartholomew's point about investment being weighed down by political uncertainty has a specific sectoral read-through. Capital goods, commercial construction, and business services that depend on corporate investment decisions could see a slowdown in order books. Companies may delay expansion plans until the fiscal picture clarifies. The Q1 GDP data showed strength in computer programming. That may reflect projects already in the pipeline. New project starts could stall.
The ONS revised January's growth from 0.1% to zero and February's from 0.5% to 0.4%. That is a net downward revision of 0.2 percentage points over two months. The quarterly 0.6% figure survived only because March came in hot. Traders should treat the Q1 number as provisional. The ONS will revise it again in future months. A data-dependent Bank of England will be watching the revisions as closely as the headlines.
Practical rule: A headline beat that relies on a single strong month, with prior months revised down, is a weaker signal than a broad-based beat with positive revisions. The Q1 print falls into the former category. The services strength is real. The momentum entering Q2 is softer than the 0.6% suggests. Traders positioning for a continued recovery are leaning on a data set that is already being chipped away.
The GDP data gives traders a baseline for sector allocation. The services sub-sectors that drove Q1 growth–wholesale, computer programming, advertising–have near-term momentum but face different levels of cyclical risk. Construction is recovering but fragile. Consumer-facing sectors are staring at a demand shock from energy and food inflation. Political uncertainty adds a fiscal risk premium to rate-sensitive sectors.
Key insight: The Q1 GDP beat is a backward-looking number that tells you what already happened. The tradeable information is in the sector divergence and the forward-looking warnings from KPMG and Aberdeen Investments. The second quarter will be shaped by energy prices, food inflation, and fiscal policy uncertainty–none of which are captured in the 0.6% print.
The next concrete data points are the April retail sales report and the Bank of England's updated inflation forecasts. Those will either confirm the consumer squeeze or suggest resilience that the economists are underestimating. Until then, the GDP print is a fading signal in a market that has already moved on.
