Banks ask how Brexit will affect customers by David Grier (Chief Technology Officer)

Martin Lewis is stumped. His recent post for on 25 need-to-knows about Brexit saw him a little at sea. On the question of what’s going to happen with mortgage, loans and savings rates, he is holding up his hands. He says, with admirable honesty:

“Mortgage, loans and savings rates could, er, rise or fall. This is a really tricky one.”

Indeed it is. And there’s a general sense that consumers are having to work things out for themselves, reading Brexit commentators and pundits like never before, whilst keeping a careful eye on their expenditure.

However, for the UK’s banks, it’s a different matter. They can’t just suck it and see. They need to able to look at the potential risks in the market of a variety of Brexit scenarios and model how these scenarios would play out across their customer base. It is imperative for them to have a handle on exactly how a rise or fall in mortgage, loans and savings rates might play out – right across their customer base – from the most secure customer to the most fragile.

Financial IQ

Never before has Castlight’s Financial IQ tool, or FIQ Insights, been more invaluable.

FIQ Insights is one of a suite of tools developed by Castlight Financial using Open Banking technology and our categorisation engine CaaS, currently the most powerful of its kind in the UK. Built into the software is not only the functionality for categorisation of income and expenditure but also a capability to track financial behaviours and predict vulnerabilities.

If we add into this the economic forecasting data from our colleagues at Experian – the UK’s leading economic forecasting group – then you have a strong set of data for which to understand you and your customer’s exposure to an economic downturn.
FIQ Insights broadly positions every customer across a bank’s portfolio in one of 5 categories, based on an analysis of their committed, discretionary and essential spending:

1. Secure
2. Comfortable
3. Ticking Over
4. Stretched
5. Distressed

Then, with customers across the portfolio allocated an FIQ spending category, a bank or other lending organisation can model for a range of scenarios . For instance, what if a no-deal Brexit caused a 2% spike in inflation or a 1% rise in interest rates? How would this affect the “stretched” customers? Would it tip them into the “distressed” category? Could it even tip some “ticking over” customers into the “distressed” category. And if so, how many?

Of course, FIQ Insights can do so much more, drilling down into the granular data in portfolios, IQ categories and accounts.

However, for now, with the Brexit deadline looming, it’s the Brexit features that are exciting credit risk experts. I can almost smell the smoke as they fire figures, data, models and Brexit scenarios into FIQ Insights to see how best to protect their customers for both the foreseen and unforeseen.

Not so tricky really Martin Lewis – if you have the right technology!

Casting light

Strength, stability and security

BBC News ran a story recently, interviewing 30 year old Scott Tacchi from Truro, who has spent the past 18 months as a lighthouse engineer, maintaining the 250 lighthouses still in use across the UK.


His job takes him to some stunning locations and he has documented not only the challenging technical tasks but some incredible storms and sunsets too. It’s an interesting read and Scott Tacchi has taken some breathtaking photographs.


After reading the BBC News feature, I found myself thinking about lighthouses, partly because we use the image of a lighthouse as an important part of our corporate brand. Lighthouses are symbols of strength, stability and security. And although the last manned lighthouse in the UK, at North Foreland in Kent, closed its doors in 1998, lighthouses continue to do their job, as they have for centuries, keeping sailors safe.

Shining a light

Our strapline is “a safer financial world” and we chose the image of the lighthouse purposefully. Like the lighthouse, it is our job to keep our customers safe, shining a light on their financial situations and guiding them safely through choppy waters. In more extreme situations, sometimes the Castlight beam illuminates someone who is drowning in debt and needs rescue.


The financial crash of 2008 has often been referred to as a tsunami and millions of people were indeed dashed against the rocks of financial insecurity. How badly we needed “financial lighthouses” then – something rooted, substantial, standing guard over a perilous situation and shining a light on it.


I have often said in these blogs that what we do every day at Castlight is try to safeguard against the credit crunch ever happening again. That’s why we create tools for lenders and individuals to illuminate and protect people’s financial security, to ensure that no-one gives or takes on credit that cannot be comfortably repaid.


In his poem The Light-Keeper, Robert Louis Stevenson refers to a lighthouse keeper as “his country’s guardian”. It is not a claim he made lightly as RLS was the grandson of the famous lighthouse engineer Robert Stevenson and knew a thing or two about the family business of building lighthouses.


And when we at Castlight seek to create a safer financial world, to be one of the country’s guardians of financial security – it’s not a claim we make lightly either.

Not waving but drowning

Over 8 million people in the UK are unable to pay off debts or household bills according to the National Audit Office’s most recent report. And this worrying statistic has subsequently generated considerable concern and column inches. However, in terms of the problem of financial distress, the millions of people in actual debt are only the tip of the iceberg.

Just this week the FCA published its Financial Lives Survey raising some serious concerns about the number of people in the UK who are not in debt at the moment – but whose finances are so precarious that one minor crisis or unforeseen expenditure could tip them over.

The survey reveals that:

* 3.1 million adults have high-cost loans

* nearly 6 in 10 (57%) of UK adults have no cash savings or savings of less than £5,000

* 7 in 10 (71%) of UK adults have no investments at all

* 31% of adults have no private pension provision

* 44% of UK adults rely or will rely on the state pension for their main source of income in retirement

Push them over the brink into debt

For many of these adults or families the unexpected cost of a boiler breakdown, a car MOT or a funeral would mean taking on more credit to cover the cost and would push them over the brink into debt.

And for some people it’s even more precarious, as a thread on Mumsnet made painfully clear. Responding to a discussion about a statistic that 2 out of 5 people have less than £100 in savings, one respondent said:

“Yep. I am in that statistic. Low paid job and crippling childcare costs. I’ve already had a cry today about my financial situation.”

Desperate times for many people.

So what can we do? We must look deeper than the tip of the iceberg to the people under the water who aren’t waving – but who are drowning.

Create a safer financial world

Our entire business is built on the objective to “create a safer financial world” and one of our key principles is to do this by helping people assess and then control their finances. There are plenty of admirable debt charities doing a tremendous job in the UK, and plenty of lenders looking to support customers too, but in order to help they need information. They need to know exactly what an individual’s income is as well as their essential, committed and discretionary expenditure. And then, armed with this transactional data, they can review arrangements or provide debt advisory support.

Our Affordability Passport uses open banking technology to allow an individual to share their transactional data with lenders or debt advisers, providing them with a real-time profile of their financial position in just a few minutes.

When money is tight or precarious, people need answers and solutions fast to ensure that disaster is averted. And the Affordability Passport allows that journey to be fast and efficient.

At Castlight we often use the image in our branding of a lighthouse casting light into a dark sea. It’s important to us that the light we cast penetrates beneath those icebergs to what lies beneath and helps to rescue the millions of people for whom debt is perilously close.

Give a man a fish

“Give a man a fish and you feed him for a day. Teach him how to fish and you give him an occupation that will feed him for a lifetime.”

 This familiar wisdom is attributed to a Chinese proverb, but it’s also a principle at the heart of many international charities working in the developing world as they empower local people to learn new skills and become self-sufficient.

 And of course, it’s effectively what we do as parents. We nurture our children through education and by example for around 18 years and then we encourage them to fly the nest and go it alone.

 We take exactly the same approach with our clients – although the process is somewhat quicker!

Watch them fly!

Most companies try to hang on to clients for as long as they can. But we do things differently at Castlight. We want them to be able to go solo as soon as possible. We like to nudge them out of the nest and watch them fly!

For us, a successful client relationship is when one of our customers that we have been working closely with for a number of months, doesn’t need us any more.

However, it’s often a bittersweet milestone as we will have spent a lot of time together. We will have co-created systems and solutions, shared ideas and strategies and ultimately built something innovative and uniquely ground-breaking to move their business forward.

 But what we have co-created belongs to the client. It has been uniquely co-crafted for the needs of a single client and designed for self-sufficiency.

Stepping back 

We’ve built in our own obsolescence – once we are confident that everything is working smoothly and that training and support systems are in place, we step back. And our client integrates the new solutions into their business model and runs with it.

We may perhaps hover a little, just to be sure everything is ok. But then, when we see the product or solution we have co-created making a real difference to their business, we let them go.

It’s a whole new customer dynamic in the world of affordability. We are re-shaping the way people do business and our customers tell us they like it. They like the process of co-creation. And they value the environment of trust – the sense that we want to stop the invoices as much as they do.

 However, once a parent, always a parent. Our offspring continue to need us at different stages in life, long after they are 18. And it’s the same with our clients. We hope they will come back to us when they need further support or solutions in the future. And like good parents, we will be there for them.

Use the Castlight brain to stay ahead of the game

The brain makes around 700 new connections each day – every time we do something for the first time or absorb new information, brand new neural pathways are formed. And the more connections we make and continue to use, the more effectively our brain works for us.

At Castlight Financial our data scientists and our customers are making connections between our products all the time. Our developers are making leaps between products, developing syntheses of ideas to create new services to meet the ever changing needs of the financial marketplace. And our clients too, are making connections, moving through one product to another, merging products, asking us to develop new products, bolting on aspects of one product to another.

And as our customers work with our developers and implementation teams, every day we see new connections being made between our customers’ pursuit of excellence and the solutions we can offer. New neural pathways are being formed, our customers’ businesses are being strengthened.

So that’s why I like to use the analogy of Castlight’s product portfolio as a brain – with neural pathways all leading off to different products – but with myriads of connections between them.

Castlight Financial portfolio of digital tools

Digital tools are too often put in a “toolkit” which is a perfectly good analogy for the way digital tools are used in many companies. But for us, I think the toolbox is too static. Once you’ve used a tool you put it back in the box and take another one out. We don’t want our customers to use our tools like that. We believe our customers will benefit if they sometimes use more than one tool at a time, if they adapt the tool as they go along, combine two tools together or get someone to run after them with a new tool that was never even in the box. And we also believe that our tools will make such a difference to our customers’ business that they will never want to put them back in the toolkit.

That’s why using the analogy of a brain to think about Castlight Financial’s portfolio of digital tools works so much better for us.

If we stay with the picture of the brain, our tools are located in different nerve centres of the brain. Some are more right brained products – intuitive, thoughtful and subjective. Products for instance like our Financial IQ, which uses customers’ transactional data to provide advanced insights into spending behaviour and reports its findings as a “persona” with a Financial IQ score and a set of uniquely individual predictive behaviours. It’s a product that understands how people think and behave. Other products are perhaps more left brained – more logical, analytical and objective such as CaaS or Categorisation as a Service. CaaS is the world’s most powerful engine for categorising and interpreting customers’ transactional data, which will, within minutes, take a customer’s raw transactional data, crunch through the numbers and split the raw data into over 180 categories of discretionary and non-discretionary spending. It’s a product where the numbers tell the story.

How it works with our customers

But of course, the right brain works together with the left brain, with neurons jumping synapses, making connections all the time. And this is how it works with our customers too.

A High Street bank, for instance, may be using CastScore to reach out to customers with thin credit files, who are normally excluded from credit, and give them a chance to be fairly assessed. Then together we identify an opportunity to take a slightly different path and use CastScore to help their customers augment a traditional credit score and radically improve it. And then our hypothetical bank may recognise that they can take Castlight’s risk management customer analytics up a gear and go down the path of implementing Castlight’s Financial IQ or test their data in Castlight’s Data Labs using our APIs to review the affordability performance of their portfolio, highlight problem areas and unlock potential for growth.

Constant changes

It’s one of our most important functions as a team to help our customers identify which pathway to go down to secure the best tools to empower them to grow, and to be robust and effective for their customers.

The open banking revolution is taking hold and taking hold fast. And banks and other financial organisations need to be more nimble and innovative than ever before. We must give our customers every opportunity to move agilely in and around our product suite, using the tools that best suit their needs today and exploring those that might suit their needs tomorrow. And back in the Castlight lab we must continue to test the products we believe our customers will need next month.

In the same way that the human brain constantly changes in response to experience, helping us learn and adapt to our environment, Castlight’s products are designed to help our customers adapt to an evolving financial landscape and predict what might be around the corner.

We Must Address Financial Wellness

More than 6 out of 10 senior HR executives in the UK have seen a rise in financial well-being issues affecting employee mental health and work performance, according to a nationwide study by financial solutions company, MetLife UK.


And just this week Insider magazine’s Ken Symon highlighted a troubling figure of £51 billion, which according to a Yorkshire Building Society and Salary Finance report, is lost to the UK’s economy each year in productivity and recruitment expenses as financial pressures make employees unable to finish daily tasks and more likely to change jobs.

Financial Wellbeing At Work

These are very concerning statistics but I think what worries me, perhaps even more, is Metlife’s findings, reported by George Elringham on the Insight website, that businesses are concerned they do not understand enough about financial wellbeing, with 66 percent saying there needs to be more clarity on best practice on tackling financial wellbeing at work.


Adrian Matthews, Employee Benefits Director, MetLife UK said: ““There is no magic solution to improving financial wellbeing in the workplace….” And I’d agree with him as far as the magic is concerned. There may not be a magic solution but where we differ is that I believe there’s definitely a solution.

The Solution

Castlight’s Affordability Passport is ultimately a financial wellness tool, which can be put directly into the hands of individuals, whether they are employed by companies or working for themselves. Many of our customers use our Affordability Passport to demonstrate their affordability to lenders, but we are increasingly seeing people use its financial wellness functionality to manage and control their day-to-day finances.


The Affordability Passport uses open banking technology to access a customer’s transactional information and uses CaaS, a powerful categorisation engine to categorise income and expenditure, across any number of accounts into over 150 categories, summarising income streams, credit commitments, essential costs and discretionary spending. The customer achieves a 3D picture of their finances, including the pressure points, areas of vulnerability and projections of problems before they happen. For one customer, the Affordability Passport may flag up that what is causing severe financial pressure is their car loan repayment plan. For another individual, it may just be that reducing spending on digital subscription packages would provide enough of a financial buffer, to ease the strain.


For some of our customers the Affordability Passport journey is reassuring and informative. It’s like a maintenance gym routine, a financial wellness routine that ensures they stay on track.

Life Changing

But for others with debt who are far from financially well it’s more like a brand new gym membership and induction course rolled into one. And it can be life changing because it sets someone back on the right path, by demonstrating to their bank that, whilst the recent financial path might have been rocky, there are patterns of sound financial behaviour that can be worked on and outcomes turned around. At Castlight we call it redemptive technology.


It’s not a magic solution. But sometimes, for someone in financial despair, redemptive technology can feel a little like magic.



The Joy Of Giving

If you’ve given something up for Lent, you’re in the home stretch now and that chocolate Easter egg, glass of wine or can of fizzy stuff is almost within reach. Millions of Christians around the world choose to deny themselves a treat during Lent and use it as a time to remember Christ’s sacrifice. And millions of people with different faiths or no faith equally use Lent to challenge their willpower, lose a few pounds and increasingly – raise money to help better the world around them.

You only have to look at UKFundraising’s website to see the range of creative fundraising campaigns which the UK’s biggest charities have devised in order to tap into this universal spirit of wanting to do something good for others this Easter.

Sense of Happiness

And giving makes us feel good – that’s a fact. At least according to results of research published recently by O’Brien and Kassirer in Psychology Today which showed that a group of people given $5 to spend on the same treat for themselves each day for 5 days, recorded a lower sense of happiness at the end of the study that the group who were tasked to spend their $5 each day on other people.

But what if you don’t have a spare fiver? What if you are up to the wire, the cheese wire even, at the end of every month? Does that disenfranchise you from the happiness of giving? I think it does.

Financial Health

Digital journalist Jack Derwin recently wrote a helpful article for the Australian edition of Your Money in which he listed 5 signs of financial health, all of which I’d wholeheartedly endorse.

But the one that really caught my attention was the fifth point where he says “the final sign of financial wellbeing is having the ability to give to others. Whether it’s supporting your favourite charity, giving to a worthy cause or helping out a friend in need, the capacity to give is a mark of true financial freedom.”

Financial Wellness

Financial wellness is not just about getting the numbers to line up on the right side in your bank account – although it is certainly about that. It’s also about holistic wellness – getting someone into a position where they are in control of their finances and therefore in control of their lives.

That’s what our Affordability Passport is all about. We use state of the art open banking technology and the world’s fastest categorisation engine to do it, but what I love is that one of the things we can achieve for our customers is one of the world’s simplest and most ancient of pleasures. The joy of giving.


Wishing You a Happy and Affordable Christmas

Every year statistics are published highlighting how badly we get ourselves into debt over Christmas and how long it takes us to recover. The numbers aren’t out yet as there’s more damage still to be done online and in the High Street. There’s still more plastic to smoulder.

But what I’ve found this year, in the run up to Christmas, are lots of websites suggesting innovative (and sometimes glaringly obvious) ways to save money at Christmas. I like the idea of stuffing a big cardboard box full of balloons for a toddler or concocting homemade bottles of rosemary infused olive oil for adults. There seems to be a whiff of nostalgia floating around the internet, a retro yearning for simpler times and maybe even a game of charades?

Pressure to Overspend

And it’s all good. We all need to resist the pressure to overspend on presents and then buy Christmas themed things we don’t need. Like a Christmas jumper. Who started that? And why have I got one?

But in amongst the thousands of words on line about the damaging effects of overspending and the creative ideas for keeping things simple, it was the voice of Lucy on Mumsnet that made me think.

“Unfortunately this month we don’t seem to have much money spare. I had put some money aside but due to an issue with my car that’s all gone.

 There is 9 people in total to buy for.

I’m spending roughly £20 – £30 per person but it will mean I have to use my credit card. I’m so careful with money normally and try to never use my credit card so I just feel like there’s a massive weight on my mind.”

Financial Blip 

Lucy hadn’t overspent this month. She’s careful with her money and she had specifically saved for Christmas. But her car broke down and her budget unravelled. Lucy is not alone – she speaks for thousands of families across the UK, who are just one financial blip away from debt.

These are the people for whom many of Castlight Financial’s products have been developed and which are now being widely used by some of the UK’s biggest banks. CaaS (Categorisation as a Service), CastScore and the Affordability Passport are all designed, in their different ways, to help banks and other financial institutions support customers who might experience a bump in the road. They provide lenders with unprecedented levels of information and insights into a customer’s finances, so that they are able to get a 3D picture of a person, their life, their financial behaviours and spending patterns and support them through difficult times of the year, like Christmas.

Thank You

I hope Lucy has a bank account with HSBC or one of the other financial institutions who use our affordability tools. Because if she does, she won’t need to tell them that she’s normally so careful with money. They will already know that. And that ability to really know  their customer means much greater financial security for Lucy, not just in December but all the way through the year.

We are proud of our affordability products and the positive impact they have had on thousands of people’s lives this year. I am confident that next year we will make even more progress. And my dream is that no-one will post messages of financial desperation on Mumsnet ever again.

Happy Christmas to everyone who has shared this blog year with me – thank you for your interest and support.

And for those of you I might see over Christmas, I hope you like your olive oil infused with rosemary?

Daredevil Plot Turns on CastScore


As season three of Daredevil explodes onto Netflix and sucks us all into the now familiar Marvel drama fest of nocturnal super-hero action, fight scenes, intrigue and love interest, I have to say I have been side-tracked a little by the brand new character of FBI Special Agent Ray Nadeem.

When we first meet Ray at his son Sammy’s birthday party, we find out the Nadeem family are in the midst of a family financial crisis. His wife Seema has had all her credit cards declined. Ray’s brother’s wife has cancer and their insurance has stopped paying for treatment. Ray and Seema have stepped in and helped cover their sister-in-law’s medical expenses. And now they are in debt.

Overwhelmed by the financial pressure, Ray asks for a raise at work and is denied. His boss tells him his low FICO score has put him out of consideration for promotion as he poses a bribery risk.

Instead, the agent is assigned the task of visiting arch villain Wilson Fisk in prison to elicit co-operation with ongoing investigations. Needless to say, it looks like Ray’s course is set on a slippery slope into well … bribery and corruption.

Not being a character in the original Marvel universe, purists may not embrace Agent Ray Nadeem as quickly as I have. But I have to confess to an ulterior motive. I’m drawn to Ray because he’s a character in the everyday universe of the world I live in too.

Financially Overstretched

He’s financially overstretched himself but he has done so with the very best of intentions. All he needed was a timely promotion, a window of time to pay off his debt, his sister in law to respond to treatment and all would have been well with his world. He would have had a routine visit to Fisk in prison and returned to his desk for a sandwich. Admittedly, this would be seriously bad TV, but in the real world, personal disaster would have been averted.

The plot all turned on a FICO score which just showed Agent Ray was in debt, not why or how likely he was to be able to repay it.

It was for people like Ray that Castlight recently launched the world’s first open-banking affordability score, providing people with a whole new way of demonstrating their creditworthiness.

Traditional credit scoring focuses on the consumer’s future credit behaviour being similar to their past performance.

CastScore, by contrast uses open-banking technology to analyse a customer’s transactional data in real time and score their likelihood of paying credit back. The AI that powers the CastScore technology has been validated on actual loan performance data, supplemented by expert analysis of spending trends with high street banks. CastScore then merges this information with transaction analytics, sourced from an up-to-the-minute review of the customer’s actual income and spend as well as a more complex analysis of lifestyle and discretionary spending.

“Redemptive” Technology

CastScore looks at and categorises every debit and credit, filling in the gaps in traditional credit data reporting and provides a 3D movie of an individual’s financial story. It gives people a chance to be fairly assessed. And it is a “redemptive” technology which allows people to make mistakes, recover from them and get back on track.

If CastScore had been checked with Agent Ray Nadeem’s FICO score, it would have shown that Ray had a good regular job, that he had a history of fulfilling credit commitments and that he had hit a blip. It would run Ray’s transactional data through financial insights and behaviour software and provide a lender with a score which reflected Ray’s 3D financial profile and the statistical likelihood of him being able to pay off his debts.

It could very easily have given him a score that would have reassured his boss, secured him the promotion and changed the world of Marvel forever.

World’s First Open Banking Affordability Score Launched By Castlight Financial

Affordability innovator Castlight Financial has developed a new open-banking affordability score, providing access to borrowing for the first time for the 5.8 million people, in the UK alone, with “thin credit files”.

The company, which has been pioneering open banking based affordability products for the last three years, including the Affordability Passport and Categorisation as a Service (CaaS), has now taken the open banking technology currently being used for traditional credit assessment and unlocked a powerhouse of additional functionality.


The new affordability score, CastScore, is not dependent on a customer having a history of credit in order to demonstrate creditworthiness and instead uses open banking technology to analyse a customer’s transactional data in real time and score their likelihood of paying credit back.

The AI that powers the CastScore technology has been validated on actual loan performance data, supplemented by expert analysis of spending trends, with high street banks. CastScore then merges this information with transaction analytics, sourced from an up-to-the-minute review of the customer’s actual income and spend as well as a more complex analysis of lifestyle and discretionary spending.

CastScore is currently being piloted by three of the UK’s High Street banks.

Says Phil Grady, CEO of Castlight Financial: “CastScore looks at and categorises every debit and credit and so it allows us to fill in the gaps in traditional credit data reporting and give customers, particularly those with thin files, a chance to be fairly assessed. Traditional credit scoring focuses on the consumer’s future credit behaviour being similar to their past performance through looking at historic credit reference agency data. The CastScore creates an up to date view of a consumer’s available disposable income and is able to predict future payment performance using more recent and relevant data. It truly represents a revolution in how lenders may view all consumers, from those with established credit profiles to those with thin files.

For the first time someone with a thin credit file will be able to demonstrate, at the touch of a button, not only that they have a regular income coming in, and that they are financially robust, but they will be able to show a set of exemplary financial behaviours which make them a very good credit risk indeed. For a financially cautious millennial with little credit history but enough money in the bank, CastScore could be the difference between securing a mortgage or being stuck in the generation rent trap.”

But it’s not only the millions of people with little or no credit footprints who will potentially benefit from the CastScore technology. A predictive CastScore, even somewhere in the middle of the range, could be used to augment a traditional credit score and radically improve it.

Says Grady: “The reason that a CastScore rating, taken by a lender in conjunction with a traditional credit score can improve a customer’s credit score is because CastScore isn’t just reviewing a history of credit repayment performance. It is instead based instead on an individual’s nuanced behaviours. The open banking technology scans all the customer’s transactional information and assesses whether the customer is a saver or a spender, do they run a tight ship or exceed their means and even are they a homebody or a party animal. It will also raise good and bad financial behaviour flags. A good flag might be that discretionary spending on charitable giving and personal health has increased. A bad flag might be unpaid bills, bank charges, increased gambling or payday loans.”

Machine Learning Powerhouse

Castlight’s machine learning powerhouse merges both the transactional analytics and the customer’s financial “story” into the CastScore which gives lenders all the enhanced predictive information they need to make a lending decision for customers with thin or no credit files. And for customers with traditional credit files, it significantly augments their financial profile, providing all parties involved with more insight, less risk and more lending scope.

An example of CastScore’s insight might be a customer who takes out a finance plan for a new car in January. This commitment may appear on a traditional credit score a few months later, if the credit score has good coverage, and only then will the credit score be updated. However, the CastScore score will update as soon as payments start being made from the account, providing financial decision makers with up to the minute information.

CastScore assesses a customer’s full financial big picture. So, whilst the new car payments may be greater than the customer’s previous car payments, there may be reductions in insurance premiums. The customer may also have taken out roadside assistance, which is statistically a good indicator. By taking factors like this into account CastScore could demonstrate that the new car was a sensible investment that in the long run cuts costs and increases financial stability.

CastScore’s algorithms have been uniquely trained to analyse the hard numbers but also to reach out into the complexity of a customer’s real life and set credit and income movement in context. CastScore’s AI brain has the computing power to demonstrate that, in a particular case, a new car may not just be an item to put on a list of credit obligations, it could be a sensible investment that in the long run creates stability in the family life and cuts costs. Ultimately that means that when the entire credit scenario is computed, it will actually factor positively in the generation of a good CastScore.

3D movie

As CastScore is being piloted with the UK’s banks as a means of enfranchising customers or helping them augment their credit scores, Castlight Financial is already developing CastScore to provide the banks themselves with significant competitive edge in a busy market place.

Says Grady: “If traditional credit scoring provides a snapshot of a customer’s affordability, CastScore provides a 3D movie. That means that any bank offering CastScore to customers is going to be able to use the enhanced modelling system to identify risk more accurately and ultimately offer better credit terms. Credit risk teams will also be able to use CastScore  for ongoing control and monitoring of customers’ finances, providing an early warning system of potential problems and allowing them to update their risk models and limits if needed.

“Open banking has already revolutionised the way we think and bank. But it’s a massive iceberg, with a huge percentage of its capability still to be exposed and exploited. By harnessing the full potential of open banking, we are powering a potential revolution in credit scoring and the wider world of banking. I believe the CastScore can help both lenders and customers access better, safer credit as well as enfranchising the millions of people with thin credit.”
