Rain Newton-Smith, CBI director of economics, said: “This quarter was a mixed picture for the financial services sector. Firms remained upbeat as profits held up, despite weak growth in business volumes in some sectors, especially banking.

“The overall headcount in financial services fell for a second consecutive quarter, driven by banks cutting staff as they make their business operations leaner, refocusing activities as a result of new capital rules and regulatory requirements.

“Despite continuing strong growth in optimism, this survey was conducted before the Budget, so it’s possible that yet another change to the bank levy may have dented the upbeat outlook in the sector.

“Firms plan to cut their marketing spend and increase their IT investment over the next year, as they focus on increasing efficiency and selling to existing customers, rather than trying to win new business.”

Kevin Burrowes, UK financial services leader at PwC, said: “UK banks are reporting growing confidence, steep revenues growth and increasing profitability, despite an unexpected stagnation in business volumes. Banks are more positive about credit risk, as the value of non-performing loans is expected to remain low in the next quarter.

Additionally, industry commentators do not expect interest rates to rise in the near future.

“Looking at the UK’s regulatory environment, banks are most concerned about cost and proportionality. Even so, the sector currently has a good grip on its regulatory agenda, and regulation is seen as less of an obstacle to growth than at any point last year.

“Banks’ spending priorities for the next year are focused on improving IT infrastructure and cyber security. Growth is seen to come from cross-selling to existing customers and attracting new domestic customers. Banks are also building new digital platforms to remain competitive and respond to changing customer needs.”
