The Bank of England took steps on Tuesday to ensure British banks keep lending and insurers do not dump corporate bonds in the "challenging" period that is likely to follow the country's vote to leave the European Union.

The central bank said risks it had identified before the referendum were starting to materialise, including lower demand for commercial property. Late on Monday, insurer Standard Life said it had halted withdrawals from its main British real estate fund.

The central bank also said it was closely monitoring investors’ willingness to fund Britain’s large current account deficit after the shock outcome of the vote, as well as high levels of household debt and the subdued global economy.

“There is evidence that some risks have begun to crystallise. The current outlook for UK financial stability is challenging,” the BoE said after its financial policy committee held two meetings after the June 23rd referendum.

Sterling

Sterling dropped more than 10 per cent against the dollar and banks' share prices fell by a fifth after the UK unexpectedly voted on June 24th to leave the EU, prompting prime minister David Cameron to say he would step down.

Sterling touched a new, 31-year low against the US dollar earlier on Thursday, hurt by Standard Life’s suspension of trading in its British real estate fund.

Twenty and 30-year British government bond yields briefly touched new record lows of 1.473 percent and 1.606 percent after the BoE’s announcement.

Mr Cameron’s Conservative Party is now selecting a new leader, who will decide how soon and on what terms Britain will leave the EU after more than 40 years of membership.

With uncertainty about the future of George Osborne as finance minister, more responsibility has fallen on Bank of England governor Mark Carney and his fellow BoE policymakers to steer Britain through its worst political crisis in decades.

Fresh signs of weakness in Britain’s economy appeared on Tuesday.

Confidence

Confidence among businesses fell sharply after the vote to leave the EU, a survey showed, and retailer John Lewis said its sales grew more slowly last week.

Britain’s dominant services industry also grew at its slowest pace in three years in June, according to a survey conducted mostly before the referendum.

As part of its announcement on Tuesday, the BoE's Financial Policy Committee said it would reverse a decision it took in March to increase the amount of capital banks must hold against cyclical upturns in the credit cycle.

Holding the so-called counter-cyclical capital buffer (CCB) at zero until at least June 2017 would reduce banks’ capital requirements by 5.7 billion pounds, potentially freeing up an extra 150 billion pounds for lending, the BoE said.

Finance minister George Osborne told parliament he planned to meet the chief executives of Britain’s biggest banks on Tuesday to discuss future action.

“The FPC stands ready to take actions that will ensure that capital and liquidity buffers can be drawn on as needed, to support the supply of credit and in support of market functioning,” the BoE said.

It has intensively monitored markets since June 24, ramping up checks it made during the 2008 financial crisis.

Turmoil

After the initial market turmoil following the Brexit vote, British lenders showed only contained demand for central funds at a six-month liquidity auction last week, including at an auction held on Tuesday.

The BoE has said the normal monthly auctions would continue weekly as a precaution.

"These measures are really about Carney aligning the Bank of England's guns in case the UK economy enters a downturn," Aberdeen Asset Management Investment Manager James Athey said.

“Markets are going to be reassured by his proactivity. He’s not waiting for anything bad to happen but rather acting in case it does.”

Mr Carney has said he believes the central bank would need to cut rates and possibly provide other stimulus over the summer to cushion the shock of voting to leave the EU.

The BoE on Tuesday gave insurers more time to adjust to new EU capital rules to avoid pressuring them to dump corporate bonds and avoid high capital charges as interest rates plunge.

Before the referendum, consumer borrowing was rising at its fastest rate in a decade while mortgage lending had eased slightly as higher taxes on landlords and second-home buyers took effect in April.

The BoE said it would keep a close eye on the buy-to-let mortgage sector, in case landlords sell up as property prices fall, as well as on the rising numbers of vulnerable indebted households.

It expressed concern about a fall in investor demand for British assets - which could make it harder for the country to finance its large current account deficit - as well as trouble in commercial real estate making it harder for businesses to use their property as collateral to obtain loans.
