The days of the banking middlemen may be numbered as a technological revolution in business lending shakes the dominance of the UK's biggest banks, a senior director of the Bank of England has said.

The rise of peer-to-peer lenders such as Zopa and Funding Circle – which directly match up firms in need of cash with investors – and so-called crowd-funding, where small amounts are raised from a large number of funders, will challenge the nation's major financial institutions, according to Andrew Haldane, the Bank's director of financial stability.

He told The Independent: "The mono-banking culture we have had since the 1990s is on its way out. Instead, we are seeing a much more diverse eco-system emerging with the growth of new non-bank groups offering peer-to peer lending and crowd-funding which are operating directly with a wider public."

Mr Haldane also held out hopes that the fledgling revolution could tackle the crisis in business lending. This helped trigger the Bank's "funding for lending" initiative in the summer to kick-start credit markets.

He said: "I see opportunity knocking for finance. Hopefully, the growth of peer-to-peer lenders and those involved in crowd-funding will help solve the problems we have with lending for small and medium enterprises ... The banking middlemen may in time become surplus links in the chain." The Government is also keen to encourage alternative finance and last week announced four peer-to-peer lenders will be given a total of £55m in taxpayers' money, an amount to be matched from private sources. The £110m fund is part of the £1.5bn Business Finance Partnership, part of the Government's drive to diversify sources of finance to business.

Zopa has lent £250m since being founded in 2005, while Funding Circle has lent £66m. Crowdcube, the crowd-funding website, has lent £4.5m since being set up in 2010 and has 25,000 registered investors. In total it is estimated the peer-to-peer industry has already advanced £300m to individuals and small businesses this year.

The sector will also have lending and borrowing activities overseen by the UK's new market regulator, the Financial Conduct Authority, from April 2014. The industry's trade body, the Peer-to-Peer Finance Association, said regulation will help to bring credibility and stability to the fast-growing industry as there have been concerns that a high-profile failure in an unregulated market would see consumers lose their money and jeopardise growth.

Mr Haldane said the rise of such lenders could bring down the costs of financial intermediation, adding: "IT has changed every other industry like film, music and even football clubs so why not finance? With open access to borrower information – which is held centrally and virtually – there is no reason why end-savers and end-investors cannot connect directly.
