Osborne's ring fence will be made of cheese wire

Power to break up the banks.

So Osborne is going to "reset the banking system". A difficult thing to do with trust between Westminster and the banks at an all time low. How is he going to do it?

Well, first there's going to be a ring-fence: but it's to be not so much electrified as made of cheese wire - if banks don't respect it, regulators will be able to break them up.

It's not just about the fence though - he also plans to make the banking sector more competitive by making it easier to switch bank accounts, and by introducing a new regulator who'll aim to help out new competitors who want to enter the game. There are also talks over how consumer power can be increased, to hold the banks in check.

There is a plus side for the banks: the leverage ratio won't be changed beyond 1:33, but as might be expected, they have not taken kindly to the news:

Anthony Browne, the head of the British Bankers' Association said:

This will create uncertainty for investors, making it more difficult for banks to raise capital which will ultimately mean that banks will have less money to lend to businesses.

"What banks and business need is regulatory certainty so that banks can get on with what they want to do, which is help the economy grow. This decision will damage London’s attractiveness as a global financial centre.

"Uncertainty" isn't really the issue though - banks have been under changing regulation since 2008. The main problem for the banks will now be flexibility, according to Credit Suisse analysts (via FT Alphaville):

Reducing options to transfer capital and funding – As we understand it, banks will be under tight scrutiny to implement strictly a ring-fence. This will clearly limit the flexibility for banks when setting-up their ring-fence plans and limit options to transfer capital and funding. Although this is hard to estimate at this stage, this could increase the overall costs of the reform for the industry. We currently do not have an impact in our estimates.

If ring-fence is to work, it needs to be enforced - but as banks make their money by finding their way around such restrictions, a truly impenetrable fence'll cost. Here is a summary of the estimated hits to the economy via FT Alphaville:

Estimates costs from implementation – The draft legislation published in October 2012 highlighted the following costs for the broader industry and economy: (i) on-going costs of £2-5bn per annum, which compares to our total profit £26.1bn for the five listed UK banks in 2014E; (ii) one-off transitional costs of £1.5-2.5bn; (iii) negative GDP impact of 0.04-0.1%; (iv) reduced tax receipts of £150-400mn (this assumes all bank costs are passed onto the consumer); and (v) a reduction in the value of the government’s shareholdings in RBS and Lloyds Banking Group in the range of £2bn to £5bn relative to a ‘do nothing’ baseline scenario (compares to current value of £45.1bn).

Who will win in Manchester Gorton?

Will Labour lose in Manchester Gorton?

The death of Gerald Kaufman will trigger a by-election in his Manchester Gorton seat, which has been Labour-held since 1935.

Coming so soon after the disappointing results in Copeland – where the seat was lost to the Tories – and Stoke – where the party lost vote share – some overly excitable commentators are talking up the possibility of an upset in the Manchester seat.

But Gorton is very different to Stoke-on-Trent and to Copeland. The Labour lead is 56 points, compared to 16.5 points in Stoke-on-Trent and 6.5 points in Copeland. (As I’ve written before and will doubtless write again, it’s much more instructive to talk about vote share rather than vote numbers in British elections. Most of the country tends to vote in the same way even if they vote at different volumes.)

That 47 per cent of the seat's residents come from a non-white background and that the Labour party holds every council seat in the constituency only adds to the party's strong position here. 

But that doesn’t mean that there is no interest to be had in the contest at all. That the seat voted heavily to remain in the European Union – around 65 per cent according to Chris Hanretty’s estimates – will provide a glimmer of hope to the Liberal Democrats that they can finish a strong second, as they did consistently from 1992 to 2010, before slumping to fifth in 2015.

How they do in second place will inform how jittery Labour MPs with smaller majorities and a history of Liberal Democrat activity are about Labour’s embrace of Brexit.

They also have a narrow chance of becoming competitive should Labour’s selection turn acrimonious. The seat has been in special measures since 2004, which means the selection will be run by the party’s national executive committee, though several local candidates are tipped to run, with Afzal Khan,  a local MEP, and Julie Reid, a local councillor, both expected to run for the vacant seats.

It’s highly unlikely but if the selection occurs in a way that irritates the local party or provokes serious local in-fighting, you can just about see how the Liberal Democrats give everyone a surprise. But it’s about as likely as the United States men landing on Mars any time soon – plausible, but far-fetched.
