Infrequent Inanity

Please stop calling them dumb pipes

Lots of people recently seem to be warning about banks becoming dumb pipes. They say banks are destined to just become the wires. The hearts and minds of customers will be won by the masters of the web. The Googles and Amazons and Apples and Paypals of the web 2.0 world. I agree they probably will but is it really a problem?

Those web 2.0 darlings are not going to make themselves into bank. The majority of them are just interested in the transaction data they don’t want the hassle of running a bank. Basel 3, MiFID and other impenetrable forms of regulation might not be too appealing.

Some may say (not me of course as I work for one) Banks have proved they don’t really get this web thing and especially not this web 2.0 thing with its rounded corners and nice fonts and helpful intuitive interfaces. Why not let the experts have a go at that bit while banks stick to what they are good at.

The banks operate a huge complex global network that moves trillions of dollars per day, usually without much issue. Complex fraud and anti-tax evasion systems operate silently. Audit requirements, data protection standards and a myriad of regulations make this system the powerful beast it is and also a potentially irreplaceable one.

No one in Silicon Valley or any other entrepreneur saturated dreamland is going to want to recreate the whole bank system (I have visions of mad stock sale billionaires from Facebook sitting in their volcano housed lairs thinking ‘we should do that’). That bank system may be a bit long in the tooth and may need some updates here and there but could we give it a chance to catch up by laying down some of these so called dumb pipes and bringing it closer to that other huge complex global network called the Internet? If we give a few more people access to the system in a web friendly way will it be of benefit to all? Will people realise the power of this network and what it allows us to do today?

Liz Lumley wrote a great post about SXSWi and how all the cool companies trying to disrupt banking are massively reliant on that network. ‘What struck me was the juxtaposition of the bravado coupled with the fairly shocking display of ignorance on how international banking and payments happen.’  These pipes are never going to be simple or dumb.

That being said I am interested in the most simple of these dumb pipes. I want an automated data feed from a current account. Every time a new transaction occurs I want a data feed I can subscribe to, just like RSS, to update. That feels very simple and you could say dumb but to make that happen is going to take some damn smart coding and some bravery.

The big problem is authentication. How do I prove I am who I say am? How do I prove that I am allowed to subscribe to that data feed? How does that authentication model satisfy banks security and fraud departments? How does it satisfy the regulators?  What would happen if someone had access to all the data behind that API? What if the Daily Mail had access?

The most simple implementation of the so called dumb pipe was planted in my head by Dave Birch. He posted the following tweet.

Setup a private twitter account. Plug it into your bank account (this dumb pipe of course has OAuth/XAuth like qualities). Follow it to catch your transactions as they happen. Now a bank would never build this. No revenue at all. It only presents risk but a customer has asked for it (albeit a quite forward thinking one who would be a guinea pig to embed payments chip into his body) but a customer need is a customer need and we know they are always right.

A few examples i have seen during my time at HSBC where customers are trying to circumvent this lack of a subscription data feed. Designer Aral Balkan was none too happy that he could only manually access transaction data from two months in the past. So he built a tool (in under 4 days) to scrape the data and save it in a format for him to upload to Freeagent. Another person, a smart gentleman going by the name Jay Fresh, went a step further. He reverse engineered online banking to produce a command line interface. I spoke with him and asked him why, his reply was that he had simply wanted to build his own iPhone app. I can understand his frustrations. Should customers have to work so hard to do this? Should they have to risk their own logon data and potentially break terms and conditions to try and get to the data? Banks spend pots of cash each year trying to figure out what customers want, why not give them the tools to build what they want. A so called dumb pipe would be a very powerful tool in the right hands.

Mr Bank 2.0 (soon to be 2.1 and available in all good book stores), Brett King, also wrote a great post on this topic (and has been talking about it for years) arguing that if the banks do become merely an infrastructure layer then they will miss out on the value built on top of it and that we may need fewer banks/infrastructure providers. I agree they might and there could be less banks but do we need that infrastructure layer to be created to allow new value chains (ugh) and innovations to truly flourish? Where would we be if we still had a fragmented electricity system? Or you could only call someone on the same telephone network as you? We need to create these commodotised infrastructural layers and allow them to weave into the wider world (web?). The innovation S-Curves of many technologies have shown this pattern. Banks may resist as the wireless telcos are doing now, except for the smart ones such as Telefonica, but I believe there is an inevitability and the banks that embrace this will be the ones that exist…but I digress.

So what would a banks dumb pipe look like? What are the technologies required to keep this mother of all honey pots safe and secure so it does not spring a sticky leak. What would be needed to build the simple sounding dumb pipe detailed above? Yes there is inherent risk on freeing customer transaction data but I think the potential benefits outweigh the risks (I may be alone on this). We are starting to see some things in the French banking market that might answer these questions SDK’s have recently been released by Crédit Agricole and this week has also seen the launch of an API by Banque AXA. The future looks French.

I look forward to the arrival of the dumb pipe. It will bring together the banking system and the web. I have high hopes for this dumb pipe. People need to realise that the pipe is not so dumb.
