The UK’s seven biggest lenders are all strong enough to cope with a “disorderly” no-deal Brexit, according to a Bank of England assessment.
But the Bank said it would consider whether the firms needed to hold billions more capital as an emergency buffer in case such a scenario coincided with a wider global downturn.
The Bank’s financial policy committee also set out a wishlist of actions required to mitigate the risks to UK financial services posed by the departure from the EU.
For the first time since the annual stress testing regime began in 2014, all the major lenders received a clean bill of health, though the weakest two – Barclays and state-backed Royal Bank of Scotland – struggled.
The tests modelled a nightmare scenario under which UK GDP slumps by 4.7% amid a wider global downturn, unemployment rises to 9.5%, the pound plunges and the Bank’s interest rate climbs to 4% – while house prices undergo a record 33% collapse.
They were carried out on Lloyds Banking Group, HSBC, Barclays, RBS, Santander UK, Standard Chartered and Nationwide.
The tests work out how much the level of capital held by each lender would fall under the “stress”.
The Bank of England said the latest invented scenario would mean banks incurring losses of £50bn over two years – a level that would, a decade ago, have wiped out their capital base.
Since then lenders have been building up their strength amid tougher standards.
In the latest assessment the Bank found that, based on their state at the end of 2016, Barclays and RBS would fall short of the required levels set for them.
However, asset sales they have carried out in the months since that time meant they would now meet targets.
The stress testing regime was put in place in the aftermath of the 2008 financial crisis to try to ensure that, should another sharp downturn occur, lending would not seize up, accentuating the difficulties faced by the wider economy.
The latest scenario included potential risks to the financial sector such as those posed by the growth in consumer debt as well as global vulnerabilities from countries such as China, and tens of billions pounds more in misconduct costs.
Governor Mark Carney said the FPC “judges that the banking system can continue to support the real economy even in the unlikely event of a disorderly Brexit”.
The stress test was published alongside the FPC’s biannual Financial Stability Report.
It confirmed that the Bank was raising the so-called “countercyclical buffer” – a back stop that can be held by lenders and be released at a time of economic stress – from 0.5% to 1%, continuing a normalisation after it was cut to zero following the Brexit vote.
That 1% level establishes an emergency buffer for the UK financial system of £11.4bn.
But the FPC acknowledged that in the first half of next year it would need to consider lifting this “in the light of the overall risk environment”.
While it had judged UK banks as being able “to support the real economy through a disorderly Brexit”, it added: “The combination of a disorderly Brexit and a severe global recession and stressed misconduct costs could result in more severe conditions than in the stress test.
