How Paypal robs the Bank of England

Digital currencies might start creating a sticky situation for central banks.

Have you ever wondered how the rise of digital currencies will impact on the monetary base, and the effects that will have on seigniorage revenue to governments worldwide? No? Well, this pair of articles by the Financial Times' Izabella Kaminska, "Why central banks should take charge of their digital currencies" and "Turning mobile money into M0" is interesting nonetheless.

Kaminska examines the typical problem central banks have with digital currencies, which is that they tend to mess around with the way banks expect the money supply of the nation to work. The immediate downside of that is that it impacts on seigniorage, the revenue accrued to a government by its right to mint coinage.

In other words, when you use PayPal rather than posting a £50 note, you need never hold that currency, and the government never receives the revenue for having printed it.

She writes:

Consequently, what you end up with is something very different to cash of the realm. In many ways, it’s worse than zero-yielding money due to the natural decay associated with transactional, creation and redemption costs. The other point is that Safaricom [the vendor of a hugely popular Kenyan mobile currency] is actually behaving much like a quasi-autonomous state within a state that’s issuing its own private money system, the value of which is constantly pegged to the official currency of the land.

How can nations fight back? (Assuming, of course, they ought to fight back — but that revenue is likely to be mighty tempting.) One possibility is by working with digital currency vendors to create payment mechanisms which don't require holding a parallel currency to work. And make no mistake, even though PayPal denominates its accounts in pounds and dollars, it's a parallel currency in all but name.

Jean-François Groff, one of the pioneers of the Web at CERN, is working on that option. Mobino, his company, is a mobile payment system which works on real-time debiting, not on keeping a float of a second currency on tap:

Mobino’s system aims to cut out as many intermediaries from the debit process as possible by getting you, the customer, to strike up a single direct debit agreement with itself. The company then charges the customer for transactions conducted with partner vendors, whilst the customer deals only with Mobino rather than a multitude of online or retail vendors.

And if that scheme was done by Mobino — or a similar system — working with a central bank, then the costs of running it could be funded from the seigniorage revenue it returns to the government. Rather than the cost of "printing" money being the actual ink and paper, it would become the price of maintaining servers and bandwidth.

In an ideal state-controlled money world, you could imagine the system mutating into one where the central bank itself ended up billing you directly for the use of their digital cash. So, rather than withdrawing physical cash to conduct your payments, you’d be transacting state-issued digital cash, now credited or debited from your account as quickly as a bank credits or debits cash to you at the ATM wall.

But, while Kaminska mentions it in passing, it would be interesting to see the analysis applied to Bitcoin. Lord knows the currency has its flaws, but it's the only one of the successful(ish) mobile payment systems which actually embraces the fact that it is a parallel currency — and a freely floating one, at that. The Bitcoin ecosystem has a specific method for distributing the seigniorage it generates, but also gradually reduces that rate; by 2140, the system will likely be in de-facto deflation.

By moving the transaction entirely into a parallel currency, the system is also more efficient than even Mobino could ever hope to be — provided you don't plan on converting Bitcoins into real-world money. If you do, things get trickier; the exchanges have had a number of high-profile failures, and are probably the weakest point in a network which manages to combine cryptographic perfection with an incredible amount of possibilities for human error.

It may be the case that central banks have to start examining what their role would be in a world of digital currencies; but if they do, it may be better for them to skip the sticking-plaster world of PayPal and Mobino and move straight to something designed for an all-digital world from the start.

What Labour MPs who want to elect the shadow cabinet are forgetting

The idea is to push Jeremy Corbyn to build an ideologically broad team, but it distracts from the real hurdle – management.

Labour MPs who have been critical of Jeremy Corbyn are pushing to vote for shadow cabinet members – rather than having all the posts appointed by the leader.

Most of the parliamentary Labour party who are not Corbyn loyalists believe this should be the “olive branch” he offers them, in order to put his recent words about “unity” and “wiping the slate clean” into action.

Corbyn and his allies have refused to consider such an idea outside of a “wider” democratisation of the party – saying that Labour members should also get a say in who’s on the frontbench. It’s also thought Corbyn is reluctant due to the shadow cabinet having three representatives on the National Executive Committee. He wouldn’t want his opponents voting for those, tipping the balance of the Committee back towards centrists.

Shadow cabinet elections were a longstanding convention for Labour in opposition until Ed Miliband urged the party to vote against them in 2011. Labour MPs on different wings of the party believe a return to the system would avoid Labour’s frontbench being populated solely by Corbyn’s ideological wing.

But there is a complication here (aside from the idea of a party leader having to run an effective opposition with their opponents in key shadow cabinet positions).

Proponents of shadow cabinet elections say they would help to make Labour a broad church. But really they could put those in the “make-it-work” camp who initially helped form Corbyn’s team in a difficult position. Initially conciliatory MPs like Thangam Debonnaire and Heidi Alexander have since left their posts, revealing frustration more at Corbyn’s management style than policy direction. Chi Onwurah MP, who remains a shadow minister, has also expressed such concerns.

One senior Labour MP points out that the problem with shadow cabinet elections lies in those who left Corbyn’s shadow cabinet but had wanted to cooperate – not in bringing ideological opponents into the fold.

“There were lots of people on his team who actually liked Jeremy, and wanted to make policy with him,” they tell me. “And many of them eventually felt they had to leave because of how difficult it was to work with him. They wanted to stay but couldn’t. If people like that couldn’t stay, will they go back? It will be much harder for him to show them he can work differently.”

One of the “make-it-work” faction voices their concern about returning to the shadow cabinet via elections for this reason. “A lot of us [who left] are still really interested in our policy areas and would be happy to help if they asked,” they say. “But it was too difficult to be taken seriously when you were actually in those shadow cabinet meetings.”

My source describes a non-collegiate approach in meetings around the shadow cabinet table, where Corbyn would read out pre-written opening statements and responses when they delivered their ideas. “It was like he wasn’t really listening.”

The plan to reintroduce shadow cabinet elections barely left the ground in a meeting of Labour’s National Executive Committee on Saturday night, on the eve of Labour conference.

This is in spite of Labour MPs urging the NEC to make a decision on the matter soon. Jon Ashworth, an NEC member and shadow minister, told me shortly after Corbyn’s victory speech that this would be “a good way of bringing people back” in to the team, and was determined to “get some resolution on the issue” soon.

It doesn’t look like we’ll get that yet. But for some who have already tried serving on the frontbench, it’s a distraction from what is for them a management – rather than an ideological – problem.
