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.

The SNP thinks it knows how to kill hard Brexit

The Supreme Court ruled MPs must have a say in triggering Article 50. But the opposition must unite to succeed. 

For a few minutes on Tuesday morning, the crowd in the Supreme Court listened as the verdict was read out. Parliament must have the right to authorise the triggering of Article 50. The devolved nations would not get a veto. 

There was a moment of silence. And then the opponents of hard Brexit hit the phones. 

For the Scottish government, the pro-Remain members of the Welsh Assembly and Sinn Féin in Northern Ireland, the victory was bittersweet. 

The ruling prompted Scotland’s First Minister, Nicola Sturgeon, to ask: “Is it better that we take our future into our own hands?”

Ever the pragmatist, though, Sturgeon has simultaneously released her Westminster attack dogs. 

Within minutes of the ruling, the SNP had vowed to put forward 50 amendments (see what they did there) to UK government legislation before Article 50 is enacted. 

This includes the demand for a Brexit white paper – shared by MPs from all parties – to a clause designed to prevent the UK reverting to World Trade Organisation rules if a deal is not agreed. 

But with Labour planning to approve the triggering of Article 50, can the SNP cause havoc with the government’s plans, or will it simply be a chorus of disapproval in the rest of Parliament’s ear?

The SNP can expect some support. Individual SNP MPs have already successfully worked with Labour MPs on issues such as benefit cuts. Pro-Remain Labour backbenchers opposed to Article 50 will not rule out “holding hands with the devil to cross the bridge”, as one insider put it. The sole Green MP, Caroline Lucas, will consider backing SNP amendments she agrees with as well as tabling her own. 

But meanwhile, other opposition parties are seeking their own amendments. Jeremy Corbyn said Labour will seek amendments to stop the Conservatives turning the UK “into a bargain basement tax haven” and is demanding tariff-free access to the EU. 

Separately, the Liberal Democrats are seeking three main amendments – single market membership, rights for EU nationals and a referendum on the deal, which is a “red line”.

Meanwhile, pro-Remain Tory backbenchers are watching their leadership closely to decide how far to stray from the party line. 

But if the Article 50 ruling has woken Parliament up, the initial reaction has been chaotic rather than collaborative. Despite the Lib Dems’ position as the most UK-wide anti-Brexit voice, neither the SNP nor Labour managed to co-ordinate with them. 

Indeed, the Lib Dems look set to vote against Labour’s tariff-free amendment on the grounds it is not good enough, while expecting Labour to vote against their demand of membership of the single market. 

The question for all opposition parties is whether they can find enough amendments to agree on to force the government onto the defensive. Otherwise, this defeat for the government is hardly a defeat at all.
