back to article Bank of England to set new standards for when IT goes bad

The Bank of England is expecting financial institutions to be a bit less rubbish when IT goes wrong, it said today. The TSB fiasco that led to customers being unable to access their accounts, followed up by widespread fraud, has caused the BofE's Prudential Regulation Authority (PRA) along with the Financial Conduct Authority …

      Never mind those three. Quake at the providers you don't think of first: IBM, HP and Fujitsu.

      I've worked at 3 banks in the last year, and two of them are big players that you will know. Every one of them has outsourced their IT to IBM and the 'IBM Cloud'. Outsourced as in

      (a) IBM now own all the IT kit. Bank leases it back.

      (b) All our infrastructure is run by IBM

      (c) Some of our IT knowledge was transferred to IBM during ramp up. We fired the rest.

      Modern banks are basically data centres with a banking license ( they are busy closing those expensive 'real' branches as fast as they can.) If IBM flops in the next downturn, the 2007 crash is going to look like nothing, as all the banks that rely on them fail.

        I think you meant *WHEN* IBM flops, not IF. Because that's the one thing they're good at.

    and there was me thinking that this was the Bank of England following El Reg's lead and defining grades of crap such as a TSB being a loss of online banking, a Barclays being a total outage requiring rollbacks and so on

    He further added that financial institutions should also be regularly testing their incident response and contingency plans, something many IT professionals would regard as Standard Operating Procedure.

    There may be many who, given the right dodgy and self-serving nature of many a financial institution, have made a decision to regularly test monied systems responses and contingency plans with incidents and zeroday vulnerability exploits and phishes.

    The secret sauce then for said financial institutions is to ensure secure slush funded payment/danegeld remuneration to friendly efficient pen-testers so that the monies so earned can be lavishly spent on making fiat currency a much more attractive enabler of novel intellectual property rather than it being squandered to try and destroy it.

    Such though may presently be much too great a quantum leap for all but the greatest of money making machines to make and take, and thus do they condemn themselves to be relentlessly exposed to ever greater losses and the catastrophic leakage of inconvenient sensitive intellectual property which guarantees their self-destruction at the hands of, and in the hearts and minds of, the cynically and designedly dispossessed.

        "This is the org that let 80% of the UKs banks blow up."

        By following a definition of inflation laid down by the then PM, former Chancellor. A definition that said increasing house prices didn't count as inflation when setting interest rates because low interst rate buy votes as well as keeping the cost of govt. borrowing down. That definitely wasn't a housing bubble you were betting the bank on. Definitely not, right up to the time it burst.

        1. HmmmYes

          Re: So basically

          Nothing to do with inflation, however it is defined.

          All to do with slack lending, the thing at the core of retail banks.

            And all to do with low interest rates set by the BoE on the basis of a fallacious inflation figure. Personal debt just kept on climbing because when it's so cheap why not borrow a bit more?

    We need a backup system

    I think we need to have some sort of alternative backup system in case of major failure. Maybe some type of metal token or small slips of plastic or paper that you could use in lieu of a debit or credit card if all else failed. Look, we're all super-patriotic these days, so you could even put a picture of the queen on them.

    Banks too big to fail ...

    but these banks have IT systems that are too big, too complex and too old and getting worse with an increase in the probability of major failure. It's not a question of 'if' now is it?

    Banks are, as Trump would have it (or not), are of national security importance- global too. The IT systems of these national security entities do not appear to be seen in a similar vein.

    It may be time, before a bank merger is allowed to go ahead, the 'proper' authorities look at the state of the parties' IT systems and any plans to integrate those systems over a period of time. I know, I'm dreaming.

    While they are at it...

    Algo-trading in my view needs to be heavily "regulated". Stock market meltdown caused by two or more inconsequential "indicators" moving relative to each other in a way that some analyst has concocted as being a "significant" trend. Does anyone know the extent such "algos" lurk in financial trading apps? I suspect many developers are not themselves aware because of complexity (how do you test every input/output?). Then there will be those that, due to a coding error, do something weird for some esoteric input combination.

    I believe that the LSE uses "random" techniques in order to reduce such systems ability to trade pre-emptively e.g., start of auction periods not dictated deterministically by the clock. Maybe having a periodic "lie-in", an hour however being a tad excessive, will assist this disruptive process.

    1. LucreLout

      Re: While they are at it...

      Does anyone know the extent such "algos" lurk in financial trading apps?

      Ken, I can answer this, but please forgive my crude attempt to squeeze what would need to be a small book or long article into a blog post.

      I'm afraid the answer is no. Nobody knows the extent of alogrithmic trading because it is extremely secretive even within an organisation. The department I write algo trading apps for does not share knowledge of them outside the business unit. If your desk knew what my desks algos did, you could write an algo to eat our lunch - make the money in our place. Desks within a bank are in competition with each other to produce revenue and obtain funding from their treasury and var from their RO's.

      Each algo operates in isolation of each other, even within our desk (business unit). I actually do understand the complexity involved in the algorithms my code implements - I won't pretend it's easy, but then we're pretty well compensated for the fact that there's very few people can do what we do.

      I suspect many developers are not themselves aware because of complexity (how do you test every input/output?)

      The testing itself is actually remarkably simple compared to what you'd imagine. Algos ultimately produce a signal which tells the OMS what to do trading wise. The data they take in to generate that isn't a wide data set, but it is fast flowing. You're usually looking at correlated pairs - so if Shell & Tesla move in opposite directions within a short space of time, the behaviour of one factors into your trading in the other - but by far and away most algos trade FX. You're swapping from USD to GBP and back, for example. There's a list of about 10 to 15 common pairs that have a large and fluid market that we use.

      When trading FX you're selling the currency you hold to buy the one you don't. My dollars for your pounds for instance. The data used for that varies but typically will be the tick data for this session and possibly a couple previous, from a number of hotspots (data sources - LSE, NYSE, Simex for example). A tick is one millisecond, so we might have say 10 data items per millisecond to process, but they're all just decimals.

      The current decimal is compared to the others for the tick in question and that is fed into the algo model which decides to either do nothing, or to change the balance we hold in the currency pair - reduce dollars and increase pounds, or increase dollars and reduce pounds.

      The second class of data is the hotspot order book - what orders exist in the market, and where they are positioned in the spread. There are three prices involved - the bid, offer, and mid price. The mid price is halfway between the bid and the offer. Bid is the price you buy at, offer is the lower price you sell at. The difference between them is the spread, which is where market makers profit.

      FX is literally a zero sum game - all that changes is the balance of currencies you hold - for me to hold more dollars, someone has to hold fewer.

      I'm massively simplifying this and trying to use terms at least passingly familiar to most people. Hopefully you can see that the inputs are readily knowable and easy to test in terms of bounds etc. I'm not suggesting mistakes don't happen (google knight capital for a great example), simply offering that the difficulty in testing is lower than that of say a 777 software system, or lane guidance system on a car.

        Thanks for that, LucreLout. And when algos crash, where go the losses ..... other than into private pockets/shady and shadowed numbered accounts?

          And when algos crash, where go the losses ..... other than into private pockets/shady and shadowed numbered accounts?

          That depends. One of my banks algos could be trading in the opposite direction to 'mine', thus my desk loses and theirs wins - they get a bigger bonus at my expense.

          If the net direction of our algos suffer a trading loss then someone somewhere wins - FX is a zero sum game - my loss is your win and vice versa. It really is that simple.

          Don't confuse algorithmic trading with tax avoidance and don't confuse that with tax evasion - they're three very different things.

          Its not really behind their backs, the only reason the algorithms are secret is that if you knew how our model responded to given market conditions you'd be able to trade against it and eat its lunch.

          I'd love to do a Reg article on this, but I already post way more details about my specialist bit of the bank (tax arbitrage) - any more detail might give away the bank, my identity, and I could quite conceivably get fired for it.

    It's funny how the scammers get their act together and produce scams to specifically prey on TSB victims quicker than the bank can get their act together.

    1. lglethal Silver badge

      All a question of motivation...

      It's a question of motivation. Scammers know they need to move quick (well they should have needed to move quick but based on TSB's response they probabaly could have taken their time) to make a profit and so are incentivised to pump out the scams fast.

      TSB know very few customers are going to go through the hassle of changing banks just because of this debacle. And when you know that, then you know there's no need to pay for that expensive overtime to repair the system or invest in things like disaster recovery, roll out testing, rolling back systems, etc. TSB's motivation is to spend as little as possible on things to do with the customers and save as much as possible to go to their bonuses.

      One motivation inspires quick action and the other does not...

    I think this is a good thing. Having worked with the BoE in the past for a very long time they are actually excellent IT wise. They analyse the risk of everything, test many technologies and lead with regards to compliance even in areas they don't need to - just to set a standard and be seen to do the right thing. They investigate if they *need* bleeding edge tech or if they are good as is.

    Many of the IT team are long timers or lifers who have turned away significant packages from banks despite having the experience and skill set to meet and exceed the positions offered.

        Re: BoE IT systems

        Until a few years ago they actually had several thousand direct customers as staff and pensioners had accounts with the Old Lady. No credit card, but a rather fancy cheque book with sort code 10-00-01 . And back in the good old days they had ridiculously cheap loans and mortgages. Mind you no chance of an overdraft facility - if you went a penny overdrawn you'd get a polite but formal letter telling you not to do it again.

        They also used to have a number of commercial accounts for Government departments such as HMRC

        All scrapped by Mervyn King as part of his drive to turn the bank into a giant economics thinktank and get rid of everyone actually interested in banking. This after a certain Scottish chancellor shafted Eddie, the previous governer, by removing all the regulatory bits and handing it to the idiots in the FSA.

    Reality bites

    Cloud is essentially the same IT hosted somewhere else. It will often have very similar properties to IT you would have hosted yourself.

    Except the management perception is that its a sort of magic that makes everything 100% bulletproof reliable forever.

    SaaS providers will use sorcery ensure their systems are far better than yours and that any kind of hiccup with system integrations or data will also be the customers "fault"

    Major assumption that our providers will take a hit if there is ever a problem. reality is that it is your own brand and business that will suffer no matter how much you tell people the root cause was contractual.

    Dear BoE,

    If you're serious about reducing IT outages, then I have a very simple step by step plan that will see off most of them:

    1) Stop outsourcing.

    2) Stop offshoring - those guys are cheap because they are low skilled and inexperienced, not because they're feeling charitable.

    3) Ensure a proper representation of developers and networks staff at senior level - If the CTO hasn't coded in 10 years then he doesn't know what's going on. Sorry, he just doesn't.

    4) Root out bad management by having mandatory 360 reviews, and if the whole team are having issues with the manager, get shot of the bad manager.

    Keep it simple and you'll get results.
