BREXIT’S dampening effect on the UK economy was highlighted again yesterday when a survey revealed growth of the key services sector had slowed to its weakest pace since March.

The services survey from the Chartered Institute of Procurement & Supply, and CIPS’s latest manufacturing and construction sector reports together point to a quarterly UK growth rate of only 0.2 per cent.

And they signal overall optimism in the UK private sector economy is the weakest since the immediate aftermath of the Brexit vote. Excluding July 2016, optimism is at its lowest for six years.

Optimism among services companies, about the prospects for increased activity on a 12-month time horizon, deteriorated last month to its weakest since July 2016.

Chris Williamson, chief business economist at CIPS survey compiler IHS Markit, said: “PMI (purchasing managers’ index) surveys showed UK business activity growing at a sharply reduced rate in October amid slower inflows of new orders and a deterioration in business optimism about the year ahead. Brexit uncertainty in particular continued to cloud the outlook, dampening current spending and investment, though other factors were also reported to have weakened demand, including global economic slowdown worries.”

He added: “Business expectations for the year ahead meanwhile slumped to the gloomiest since the Brexit vote [aftermath]. With the exception of July 2016, the degree of optimism was the lowest for six years, down to levels last seen during the height of the eurozone debt crisis. Optimism deteriorated in all three sectors but waned most sharply in the construction sector.”

CIPS’s business activity index for services tumbled from 53.9 in September to 52.2 in October on a seasonally adjusted basis. Although the index remained above the level of 50 deemed to separate expansion from contraction, it signalled the weakest pace of services sector expansion since March. The latest reading is the second-weakest since July 2016, CIPS noted.

New business growth recorded by services companies in October was the weakest since July 2016, having slowed for the third time in four months.

CIPS said: “A number of firms noted that Brexit-related uncertainty and concerns about the global economic outlook had constrained demand growth for business services. Some survey respondents also commented on subdued consumer spending in October. Consumer-facing sectors such as hotels, restaurants and leisure reported the weakest performance.”

Mr Williamson said: “The disappointing [services] sector numbers bring mounting evidence that Brexit worries are taking an increasing toll on the economy. Combined with the manufacturing and construction surveys, the October services PMI points to the economy growing at a quarterly rate of just 0.2%, setting the scene for GDP (gross domestic product) growth to weaken sharply in the fourth quarter.”

He added: “However, while it is not surprising to see that Brexit uncertainties are increasingly undermining business activity at this stage of the negotiations, the survey responses also suggest that the economy is facing other headwinds, including a broader global slowdown, trade wars, heightened geopolitical uncertainty and tightening financial market conditions.”

CIPS director Duncan Brock said: “A reluctance to commit was the message coming through loud and clear from service providers in October as the sector checked in with its worst performance since March and lowest optimism since July 2016.

“Many of the respondents attributed this poor performance...to continuing ambiguity around the Brexit negotiations.”
