What does an analyst give the bank in terms of money?
It is through these indicators that bank owners and managers look at the data.
More sales per customer
Fewer credit losses
Accurate capital planning
Lower operating costs
In this article, we will analyze 10 practical scenarios for using analytics in banks.
You will see:
- what solutions are already being used by international banks
- what results they achieve
- what data and infrastructure are needed to run such scenarios
- where analytics can have the greatest business impact
In the material, we rely on the experience of our company Cobit Solutions and open cases of international banks, since due to NDA we cannot name clients from our own banking projects.
Let’s start with the question that comes first for any business.
OPERATIONAL EFFICIENCY
How to reduceÑ– bank operating costs
Now let’s move on to Cost-to-Income. Where does the bank spend money every day? Cash, collection, employee labor, maintenance of a large network of equipment.
On the scale of a large financial institution, even a few percent savings turn into significant amounts.

01
Real-time hyper-personalization
Let’s imagine a client who has just purchased airline tickets. For the bank, this is a signal: in the near future he may need insurance, favorable conditions for payments abroad or another travel product.
There can be hundreds of such signals: an increase in the balance, a regular payment, a change in the cost structure, a new large transfer. Predictive analytics allows you to process these signals and determine which product is most likely to interest a particular client.
In our experience, personalized offers can attract the attention of customers 2–3 times more often.
Personalized offers can be 2–3 times more likely to attract customer attention.
02
Predicting customer churn
When should you start working with a client who may leave? The best time is before the account is closed. The first signals appear earlier. The client uses the card less often, transfers regular payments to another bank, reduces balances or reduces account turnover.
Predictive analytics helps to combine these changes and identify clients with a high risk of churn.
In one of our cases, a European bank used machine learning to predict the churn of banking customers. A targeted campaign helped increase the level of active client retention by 18%.
Higher customer retention.
03
New sources of revenue from data
Can data help a bank find additional sources of revenue? Yes. Aggregated analytics allows you to study consumer activity, payment structure, behavior of individual segments, and changes in demand. Based on such findings, a bank can find new opportunities in existing products or create separate analytical services for corporate clients and partners.
In one of the cases Visa a large American card issuer used analytics to identify lost opportunities for generating commission income. After the changes, the portfolio’s return increased by 3%, and the bank began to receive an additional $100,000 per year.

INCOME PROTECTION
How does analytics protect bank capital?
04
Next-generation credit scoring
Two clients may have similar credit ratings and completely different levels of risk. For a more accurate assessment, the bank can use predictive analytics built on machine learning models. Such models take into account cash flow, transaction behavior, business characteristics, and other available factors.
Based on this data, it is possible to more accurately assess the probability of loan default. The results of the analysis help when making a decision, determining the limit and rate, and further monitoring the borrower.
In our experience, using ML models helps reduce the risk of problem loans by 15–20%.
15-20 % lower risk of problem loans
05
Early detection of problem loans
The loan has been granted. What happens to the risk next? After all, the borrower’s financial condition can change. A drop in turnover, a decrease in revenues, an increase in debt burden, and a change in payment behavior can indicate a future problem.
The early warning system based on predictive analytics collects such signals and forms a list of clients that need attention.Â
So the risk team gets the opportunity to work with them earlier and set priorities correctly.
In World Bank 2025 study, ML helped prevent 67.6% of incidents that could have led to financial losses.
67.6% of financial losses were prevented
06
Intelligent Antifraud and AML
One suspicious transaction may not show anything. But what if you look at the entire chain?Â
Machine learning and network analysis help find connections between accounts, payments, and participants that remain invisible when checking individual transactions.
A case in point is the international project Aurora of the Bank for International Settlements.
During testing, the combination of machine learning, network analysis, and data protection technologies allowed detectingup to three times more complex money laundering schemes.
The number of false positives was reduced by 80%.
up to 3× more complex AML schemes · 80% fewer false positives
07
Stress Testing and Capital Planning
What will happen to a bank’s portfolio during a deep recession? Scenario modeling helps answer this question. A bank can estimate potential losses, revenues, expenses, and capital levels under different economic conditions.
In 2026, the Federal Reserve examined 32 large banks, including Bank of America, JPMorgan Chase, Citigroup, Goldman Sachs, Capital One, and Wells Fargo.
Under a deep global recession scenario, cumulative losses could exceed $708 billion, and the Tier 1 capital ratio would decline by 1.6 percentage points.Â
At the same time, all 32 banks maintained capital above minimum regulatory requirements and were able to continue lending.
$708 billion of potential losses identified for just part of 2026
In addition to regulatory reviews, banks can conduct their own internal stress tests for specific risks and management tasks. For example, they can simulate a sharp increase in delinquencies, a change in interest rates, or a deterioration in the situation in a particular credit segment. Such calculations help to assess the capital buffer in advance, adjust credit policy, and prepare for possible changes in the market.

Cash handling optimization
How much cash does a particular ATM need tomorrow? The answer can be predicted. The model takes into account transaction history, day of the week, seasonality, holidays, location, and other factors. Based on the forecast, the bank plans ATM replenishment and collection routes.
Cobit Solutions estimates that cash handling can account for 5–9% of a bank’s total operating costs. However, almost half of our clients used manual calculations to forecast branch and ATM needs.

09
AI assistant for bank employees
How much time does a bank employee spend searching for a document, internal policy, or necessary instruction?
A corporate AI assistant can find information, summarize documents, and help prepare for a meeting. Such solutions are already being used in real banking processes.
One ​​of the most striking examples is Bank of America. Erica’s internal assistant is used by over 90% of bank employees, and the number of calls to IT support has decreased by more than 50%.
employees use Erica, and the number of support requests has decreased by 50%

Predicting ATM Failures
ATM failures can also be predicted. The equipment constantly generates event logs, error messages, and technical indicators. Machine learning models analyze this data and find signs that may precede the failure of individual components.
This approach was used by Bank of New Zealand. The predictive maintenance system helped the bank reduce ATM downtime by a third, reduce errors by 65%, and maintenance costs by 30%.

Why is a good script not enough?
Let’s say a bank wants to launch personalization. Where does the data reside? Some of it is in CBS. Some is in CRM, card processing, mobile banking, and credit systems.
Metrics can have different formats, calculation rules, and update frequencies. Combining these sources creates the most complex part of an analytics project.
Data silos
Most of the scenarios described require information from multiple systems at once. Therefore, the first task is to integrate the sources and create a common data environment.
Data
quality
The model inherits the problems of the original data. Duplicates, omissions, different calculation rules, and errors directly affect the result.
Outdated architecture
New solutions often integrate with systems that have been operating for decades. The architecture must ensure stable data exchange and the ability to connect new scenarios.
Lack of expertise
A full-fledged analytics system requires architects, data engineers, BI specialists, analysts, and machine learning specialists. The team must simultaneously understand the technology and the bank's business objectives.
Security and compliance
Access to banking data requires clear rules. Roles, logging, privacy, model control, and regulatory compliance are built into the project architecture.
As a result, a separate scenario turns into a system task.
Technical basis
