Based on this analysis customer behavior, changes, and improvements are created in the interface of the customer onboarding page and overall processes. Additionally, using such technologies, multiple processes like onboarding can happen from anywhere, in minutes with just a few clicks.   

Furthermore, document processing, which is traditionally a crucial and labor-intensive task, has been made easy and efficient using machine learning. It decreases the time taken to organize, label, classify, and process financial documents. Moreover, when the optical character recognition (OCR) feature is applied, ML models can manage and process paper documents as well.   

Traditional banks that still rely on paper forms during the onboarding process, hence, too stand to benefit from ML-based document processing. Scanning an ID or an invoice is made easy using machine learning.   

2. Fraud Detection and Prevention   

The banking and finance industry is a common place for fraudsters and hackers. Due to its monetary nature and huge scale of operations, the sector is bound to have some loose ends, loopholes, and gaps, and attracts many notorious minds.   

Machine learning here plays a pivotal role. Banks and financial institutions use ML for fraud detection. AI and ML can evaluate huge amounts of data and data sets of simultaneous transactions in real-time, to identify any anomalies. It minimizes human intervention and updates the models to keep pace with the time and new fraud tactics.     

Fraud Detection Process

Using ML, banks and financial institutions label past data as fraudulent or not fraudulent. It allows them to keep training the ML models to detect potential future anomalies, by inserting large volumes of historical data and initiating analysis of customer behavior and patterns. ML models can additionally assist banks with quickly identifying user activity, verifying it, and managing cyber-attacks quickly and effectively.  

Danske Bank implemented an ML-driven fraud detection system. It was picking up 1,200 false positives per day in its transaction monitoring and 99.5% were false positives in fact, before ML intervened.    

With machine learning they were able to reduce false positives by 35% and improve the detection of true positives and actual fraud at the same percentage. Additionally, with deep learning, the numbers almost doubled to a 60 % reduction in false positives and an almost 50% improvement in detecting actual fraud.   

3. Portfolio Management  

Portfolio management is a crucial aspect of the banking and finance industry. It uses statistical points of the issue and automated algorithms to digitally manage wealth as well as optimize the client’s asset performance.  

Clients add their financial goals or other details and aims, and the robot advisor then suggests and assigns some current assets to investment variants and opportunities.   

BlackRock Investment Company, for example, offers Aladdin, an OS that provides investment managers in the FinTech sector, with risk analytics and portfolio management software tools, using ML.   

4. Process Automation  

From bank audits, and document processing, to employee training and management, all these mundane yet important tasks are automated using machine learning. ML techniques facilitate the review of thousands of pages, and identification of important documents, details, and information. This saves banks billable hours and resource requirements and enhances the efficiency of services.   

Some examples of process automation in banking and finance using ML include chatbots, paperwork automation, and employee training gamification.   

Quontic, a US-based bank, adopted an ML-powered task automation product to work in tandem with its legacy platform. With this solution, the bank recorded a 210% increase in the total number of banking customers along with a 261% increase in retail deposits, among other things.   

5. Regulatory Compliance  

Regulatory compliance is an indispensable aspect of the fintech industry. Failure to comply can cost an institution a lot of time and money. Additionally, an investment of even billions does not necessarily mean effective compliance. The machine helps with this.   

RegTech or regulatory technology applications are used to ensure regulatory compliance for banks and financial institutions. ML algorithms scan and learn from regulatory documents which helps them to conveniently recognize correlations between guidelines.   

They help the fintech industry to comply with ever-changing regulations in the financial landscape by constantly tracking and monitoring regulatory changes in real-time. ML enables these organizations to detect anomalies and make sure that every transaction complies with regulatory requirements.  

6. Credit Scoring  

Credit scoring is done to evaluate the credit history and worthiness of a customer. It informs about the likelihood of repayment of credit or debt by the customer.   

ML scoring decisions are taken factoring in a lot of elements and as a result a lot of data such as work experience, earnings, past transactions, and analysis of the same and credit history. A mathematical model based on accounting and statistical methodologies, the solution can provide more accurate and reliable credit score assessments than traditional systems.   

These systems do their work without biases, discriminatory opinions, and room for human errors. It has enabled banks and financial institutions to cater to a wider audience and credit seekers in a more fair and equitable manner.  

Equifax, for example, uses ML along with other FinTech solutions in credit scoring to offer credit ratings and demographics to businesses. Additionally, it offers commercial credit monitoring and fraud prevention services directly to consumers.  

7. Hyper Personalization and Customer Retention  

Analytics from machine learning help banks and financial institutions to personalize customer interactions and experiences through offers and services that are tailored to their needs. Using ML, the banking and finance industry monitors and predicts customer churn by monitoring behavioral changes. Personalized services also allow institutions to forge and nurture customer relationships. 

Chatbots are also used to personalize the customer experience and as a powerful customer service tool. Bank of America’s ML-powered chatbot Erica, launched in 2018, has handled around 1 bn customer interactions so far.   

Further, after 4 years of continuous training, testing, and self-improvement, the bot was capable of solving over 1mn unique customer queries in 2022. And more importantly, she can offer personalized financial advice to the bank’s customers.   

Customer acquisition is harder than retention. Hence, banks use ML-enabled analytics to identify customers who could discontinue opting for the institution’s services soon and act quickly to retain them. Machine learning helps to personalize the customer journey and retain customers.   

TransUnion bank, for example, partnered with ML-powered budgeting app Mint, to offer tips on credit score enhancement to its customers, driving loyalty and increase in customer lifetime value.   

Benefits of Machine Learning in Banking  

As noted above, there are multiple machine learning use cases in the banking and finance sector. But why?   

The primary reason why machine learning is so successful in the banking and finance sector is the data-rich nature of this industry. Machine learning uses as well as thrives on data, the greater the amount of data, the better the results.   

The accounting record and other numbers that the finance industry has been saving up for decades would finally be leveraged to derive market and customer insights and drive business growth.
