Confidence slumps to near four-year low as businesses nurse painful Iran war hangover

Author: ICAEW

Published: 02 Jul 2026

Business confidence in the UK has sunk to a near four-year low as firms count the mounting cost of the Iran war, a survey of 1,000 business leaders published today has found.
  • Sentiment lowest since Q4 2022 amid geopolitical risks and rising costs
  • Confidence in its joint-longest negative streak since global financial crisis
  • Financial worries grow as late payment concerns hit five-year high

Sentiment tracked by ICAEW’s Business Confidence Monitor (BCM) stood at -14.6 on the index in Q2 2026, the lowest reading since Q4 2022 and down sharply from -1.1 in the previous quarter. Confidence has now lingered in negative territory for six successive quarters, the joint-longest streak since the 2008 global financial crisis. [1]

Negative confidence readings typically coincide with difficult periods for businesses and the UK economy, such as the significant inflation shock that followed Russia’s invasion of Ukraine in 2022, ICAEW said.

The fall in confidence likely reflected weaker expected sales activity and rising costs pressures, amid growing geopolitical turbulence, ICAEW said. Projected growth in sales, gross profits and turnover for the year ahead all slowed in Q2 as concerns over customer demand increased. [2]

Geopolitical risks were the biggest growing challenge to performance with 65% of companies citing this as an issue, likely reflecting the fallout from the Iran conflict and increasing domestic uncertainty as a change of prime minister looms large.

Labour costs (58%) were the second biggest challenge amid the notable minimum wage increase during the survey period, followed by energy costs with the percentage of firms highlighting this issue rising sharply from 35% in Q1 to 55% in Q2. The closure of the Strait of Hormuz and rising fuel prices meant the share of businesses citing transport worries nearly doubled from 11% to 20%, the highest for over two years.

Sentiment was negative in eight of the nine sectors surveyed with confidence most negative in business services (-20.7), followed by property (-19.3). In contrast, confidence among energy, water and mining firms was strongly positive (10.5).

Alan Vallance, ICAEW Chief Executive, said:

“These findings are a sobering reminder of just how exposed UK businesses are to global instability. The war in Iran has knocked confidence significantly and the economic consequences are proving hard to shake.

“Our research shows that most businesses are increasingly troubled by geopolitical risks, and frankly, it’s hard to see these worries easing until hostilities truly subside. With a summer of domestic uncertainty on the horizon, the next prime minister must prioritise cultivating the conditions for companies to thrive and grow, including reducing the complexity, cost and uncertainty that are holding them back.”

Suren Thiru, ICAEW Chief Economist, said:

“Our survey signals a torturous second quarter for the UK economy, as the Iran conflict sent business costs skyrocketing and sapped expectations for future sales, driving sentiment into a steep decline.

“While this disheartening drop in confidence was broad-based, the business services sector was hit especially hard, with growing uncertainty, elevated labour costs and rising regulatory pressures all weighing on sentiment.

“Businesses are responding to strengthening cost pressures with only limited price rises, indicating that weaker demand means many firms are struggling to fully pass higher costs on to customers, squeezing profit margins.

“Even if the peace deal holds, the weakening in forward-looking sales indicators points to a difficult second half of the year for the UK economy, as the aftereffects of the Iran conflict continue to weigh on activity.”

Cost pressures mount as global pressures intensify

Input prices ticked up to 4.1% in Q2, the highest since Q3 2024, reflecting higher input costs and global pressures, while businesses raised their forecasts for the rate of input cost growth over the next 12 months to rise to the highest level since Q1 2023. In contrast, salary growth slowed slightly in Q2 and is predicted to slow in the year ahead, the BCM found.

Selling price inflation edged up to 2.5% in Q2, its highest level since Q4 2024, with expectations for the next 12 months increasing to the highest point since Q1 2024.

By sector, the prices charged to customers by energy, water and mining firms are expected to rise by most in the year ahead, followed by transportation and storage.

Concerns over late payments hits five-year high

In a further sign of the financial stress on businesses, 24% of firms cited late payments as a growing challenge, the highest proportion since Q1 2021. Concerns over bank charges also ticked upwards to 10%.

By sector, worries over late payments were highest among firms in construction (37%), IT and communications (30%) and transport and storage (28%).

As one of the largest and most comprehensive quarterly surveys of UK business activity, BCM is closely watched and referenced by key policymakers, including HM Treasury, the Bank of England (including being referenced in their Monetary Policy Report), and the British Business Bank. 

  1. The previous six successive quarter period that confidence was in negative territory was between Q2 2018 and Q3 2019.
  2. Projected growth in domestic sales (4.8%), exports (4.0%), gross profits (4.7%) and turnover (5.4%) slowed in Q2 2026.
  3. The Business Confidence Monitor (BCM) began in 2004. 
  4. 1,000 Chartered Accountants based in the UK responded to a telephone survey between 13 April and 19 June. Businesses were categorised in terms of size (number of employees), region and industry sector. Regional classification used was ONS Government Office Regions.  

Business Confidence Index methodology - The Business Confidence Index is calculated from the responses to the following:

“Overall, how would you describe your confidence in the economic prospects facing your business over the next 12 months, compared to the previous 12 months?”   

A score was applied to each response as shown below, and an average score calculated: 

Variable Score
Much more confident +100
Slightly more confident +50
As confident 0
Slightly less confident -50
Much less confident -100

Using this method, a Confidence Index of +100 would indicate that all survey respondents were much more confident about future prospects, while -100 would indicate that all survey respondents were much less confident about future prospects.
