How to set Libor in a post-Barclays age

Time for the banks to have some skin in the game

The Libor-fixing scandal is obviously problematic for a number of reasons, but one of the biggest ones is that it isn't entirely clear how to prevent it happening again. The only reason we know for sure the rates were artificially set are the (still astonishing) internal emails from Barclays requesting that.

The issue is that, certainly at the height of the financial crisis, and even now, Libor relies on self-reported rates. Banks rarely actually borrow in large quantities from the inter-bank market any more, so rather than reporting what they are borrowing at, they are forced to report what they think they could report at. The problem then is that unless you have cast-iron evidence that there is an ulterior motive, its hard to distinguish rate-fixing from just not really guesstimating your rates very well.

Some have responded to this by arguing that the replacement to Libor should be based on actual borrowing. If a bank isn't borrowing on the inter-bank market, they report some other similar cost of capital; if they aren't borrowing at all, they don't submit. But in the FT today, Frank Partnoy comes up with another, more ingenious solution:

The teeth of the new regulation would be a rule requiring the bank that submitted the lowest Libor estimate to lend a significant amount of money, say $1bn, to the Libor Trust at its submitted low rate. Conversely, the bank submitting the highest Libor estimate would be required to borrow the same amount from the Libor Trust, in the relevant currency for the specified period of time, at its submitted high rate.

So if Barclays under-reports its rate by 1 per cent and finds itself the lowest reporting bank, it suddenly loses out on $10m over the course of a year. And the same problem if it over-reports. If, meanwhile, RBS over-reports by 1 per cent, it loses out on the same; and the trust in charge of setting the rates pockets the $20m difference (which could then go towards running costs, into the Treasury, or some other noble cause).

If there is a problem with that, it's that it may not be entirely painless to be forced to borrow $1bn even at accurately reported rates. But that seems like a small price to pay for regenerating trust in a system which has suffered a severe blow.

Why Chris Grayling is Jeremy Corbyn's secret weapon

The housing crisis is Labour's best asset - and Chris Grayling is making it worse. 

It feels like the classic Conservative story: wait until the election is over, then cancel spending in areas that have the temerity to vote Labour. The electrification of rail routes from Cardiff to Swansea – scrapped. So too is the electrification of the Leeds to Manchester route – and of the Midland main line.

But Crossrail 2, which runs from north to south across London and deep into the capital's outer satellites, including that of Transport Secretary Chris Grayling, will go ahead as planned.

It would be grim but effective politics if the Conservatives were pouring money into the seats they won or lost narrowly. There are 25 seats that the Conservatives can take with a swing of 1 per cent from Labour to Tory, and 30 seats that they would lose with a swing of 1 per cent from Tory to Labour.

It wouldn’t be at all surprising if the Conservatives were making spending decisions with an eye on what you might call the frontline 55. But what they’re actually doing is taking money away from north-west marginal constituencies – and lavishing cash on increasingly Labour London. In doing that, they’re actually making their electoral headache worse.

How so? As I’ve written before, the biggest problem for the Conservatives in the long term is simply that not enough people are getting on the housing ladder. That is hurting them in two ways. The first is straightforward: economically-driven voters are not turning blue when they turn 30 because they are not either on or about to mount the first rungs of the housing ladder. More than half of 30-year-olds were mortgage-payers in 1992, when John Major won an unexpected Conservative majority, while under a third were in 2017, when Theresa May unexpectedly lost hers.

But it is also hurting them because culturally-driven voters are getting on the housing ladder, but by moving out of areas where Labour’s socially-concerned core vote congregates in great numbers, and into formerly safe or at least marginal Conservative seats. That effect has reached what might be its final, and for the Conservatives, deadly form in Brighton. All three of the Brighton constituencies – Hove, Brighton Kemptown and Brighton Pavilion – were Conservative-held in 1992. Now none of them are. In Pavilion they are third, and the smallest majority they have to overcome is 9,868, in Kemptown. The same effect helped reduce Amber Rudd’s majority in Hastings, also in East Sussex, to 346.

The bad news for the Conservatives is that the constituencies of Crawley, Reading, Swindon and in the longer-term, Bracknell, all look like Brightons in the making: although only Reading East fell to Labour this time, all saw swings bigger than the national average and all are seeing increasing migration by culturally-driven left-wing voters away from safe Labour seats. All are seeing what you might call “Hackneyfication”: commuters moving from inner city seats but taking their politics with them.

Add to that forced migration from inner London to seats like Iain Duncan Smith’s in Chingford – once a Conservative fortress, now a razor-thin marginal – and even before you add in the appeal of Jeremy Corbyn’s person and platform, the electoral picture for the Conservatives looks bleak.

(It should go without saying that voters are driven by both economics and culture. The binary I’ve used here is simplistic but helpful to understand the growing demographic pressures on the Conservatives.)

There is actually a solution here for the Tories. It’s both to build more housing but also to rebalance the British economy, because the housing crisis in London and the south is driven by the jobs and connectivity crisis in the rest of the United Kingdom.

Or, instead, they could have a number of measures designed to make London’s economy stride still further ahead of the rest, serviced by 5 per cent mortgages and growing numbers of commuter rail services to facilitate a growing volume of consumers from London’s satellite towns, all of which only increase the electoral pressures on their party.
