What is Data Science?

Data Science is a method of studying large volumes of structured and unstructured data via modern analytical tools.

In 2021, the volume of collected data increased by 37% over 2020 and reached 74 trillion gigabytes. The numbers are absolutely striking.

The volume of data on the Internet

Not only has the volume of data grown; so has the variety of data being gathered. This leads to difficulties in analyzing and structuring information that would present a daunting task for humans. That’s where Data Science comes in.

Data Science allows companies to receive comprehensive data analysis, predictions, and insights that can be used to improve every sphere of the organization’s processes.

Data Science combines several fields such as:

  • statistics;
  • mathematics;
  • quantitative finance;
  • data analysis;
  • algorithmic development; and
  • visualization.

This combination of tools allows companies to perceive information more easily and find correlations among seemingly unrelated things.

An especially large volume of data gathered by organizations comes from the field of fintech. But how to analyze financial data? We’ll explain below.

The Role of Big Data in Fintech

Put simply, the term Big Data refers to a large amount of unstructured and unprocessed data that was gathered from various channels.

Due to the rapid development and advancement of modern technologies, such as IoT and mobile technologies, the fintech industry is collecting more and more financial data types, such as balance sheets, income statements, and other financial data examples for analysis. This analysis helps financial institutions understand their consumers better and develop well-thought-out strategies.

The concept of  Big Data is based on principles that might be called the three Vs:

  • Volume. Traditional technologies cannot collect such a tremendous amount of data, so there have to be special methods and technologies for Big Data collection.
  • Velocity. Data needs to be processed in real-time to get up-to-date information.
  • Variety. Technologies should be able to process a great variety of data formats, such as audio, video, and even tweets.

Using the right approaches to handling Big Data, fintech institutions can derive benefits such as:

  • Improving the customer experience;
  • Increasing safety;
  • Enhancing the quality of services;
  • Improving decision making;
  • Meeting customer expectations.

To garner these benefits, data must be processed using special algorithms. And that is the mission of Data Science.

The more data the algorithms analyze, the more comprehensive and relevant the results will be. This explains the popularity of Data Science in the fintech industry, as there are huge amounts of data gathered in this field.

By using Data Science, financial institutions can make well-reasoned decisions and provide a personalized customer experience.

But how exactly can companies implement Data Science? Let’s examine that more closely.

Use Cases of Data Science in Fintech

Below are some of the most common Data Science use cases in fintech, where the technology is a necessity or at least a highly desirable feature.

Fraud Prevention

Fraudsters stealing company data and money is a nightmare scenario for every financial organization. So, they’re using every anti-fraud tool available to defend information.

For example, companies can implement Regulatory Technology, or Regtech, to strengthen security systems. This includes:

  • intelligence applications for Anti-Money Laundering (AML);
  • a single-risk platform for end-to-end fraud protection;
  • blockchain technologies for increasing the safety of direct transactions;
  • Machine Learning for communication monitoring and customer identification.

Also, Machine Learning algorithms can analyze the latest consumer experience and compare it to all previous activities. This enables organizations to proactively react to unusual actions.

By the way, small banks and credit unions are more likely to be attacked by fraudsters than bigger financial institutions. So, the combination of financial data analysis and Machine Learning analytics is an important means of protecting financial organizations of all sizes and their financial databases from falling victim to fraudulent activities such as speculator trading, rogue trading, and regulatory violations.

Risk Analysis

Data Science provides an organization with deep risk analysis and helps manage risks by implementing new features of risk detection systems.

Organizations can prepare for potential problems by simulating particular risks in a virtual environment. For example, they can perform risk analysis to see whether a potential borrower is likely to actually repay the loan. Risk simulation helps companies to understand the risk preconditions and monitor them effectively across the corporation.

Data Science creates a risk model based on the history of consumers’ transactions. It helps to determine if users are reliable and, if so, can offer them benefits such as lower rates and additional services.

Also, risk assessment via Data Science can improve audit management, as creating a risk assessment plan is a vital part of the auditing process.

Customer Behavior Analysis

Data Science analyzes a large amount of behavioral data using text analysis, natural language processing, and data mining.

Customer behavior analysis allows financial companies to:

  • boost cross-sales by offering customers additional products or services of interest;
  • estimate and increase clients’ lifetime value;
  • reduce losses by decreasing below-zero-value customers;
  • divide customers into segments;
  • enhance the business’s reputation as a trusted partner.

Data Science combines the opportunity of creating customer behavior models and conducting real-time and predictive fintech analytics.

Credit Allocation

In this case, fintech Data Science analyzes banking databases and open financial data provided by clients along with their credit history. Also, particular banks have the right to exchange some financial information, which provides the opportunity to gather more data about clients.

This helps banks automate the process of defining the credit score of each client. No manual labor is required to predict whether the client is a good candidate for a loan.

Moreover, Machine Learning can match users’ behavior to credit scoring models and predict how likely the customer is to repay the loan.

Predictive Analytics

Predictive analytics extrapolate from current data to forecast future trends. Thus, fintech Data Science can help to predict stock trends and market prices and help users make wise investments or develop financial strategies.

Product Improvement

One more way of using Data Science is to create product improvement strategies. It helps organizations adapt to changing market demands, understand the weaknesses of the company’s products, and modernize them.

Data Science, combined with Artificial Intelligence, allows financial firms to introduce new products to users at the most favorable time when the market is the most responsive.

Algorithmic Trading

Algorithmic trading is a set of instructions programmed to solve trading issues, taking into account variables such as price, timing, and volume.

In developed markets, today around 70-80% of all trades are algorithmic, and these numbers are expected to grow up to 95% in the next few years.

Prevalence of algorithmic trading

Algorithmic trading uses mathematical formulas and models, along with human oversight, to find even the least obvious opportunities for successful trading. This combination allows firms to define whether it is effective to trade on a particular market at a particular time.

The big benefit of using special fintech Data Science applications is the speed of actions and reaction to the consequences. The algorithms ensure that if a particular step turns out to be wrong, the program will correct the decision-making model, taking the mistake into account.

Personalized Marketing

Thanks to in-depth analysis of trends and customers’ preferences, financial companies can offer personalized ads and products for each segment of users.

Personalized marketing campaigns help to reach the target audience, improve customer retention, and make for a better user experience.

Personalization also improves the conversion rate and increases the return on investment, leading to better financial performance of the organization.

How Data Science improves personalized marketing

As you can see, financial data analysis can be used in a broad variety of spheres in the fintech industry. But a lot of attention is given to the correlation between Big Data and customer experience. We’ll explain that correlation below.

How Can Big Data in Fintech Influence the Customer Experience?

Using Big Data, fintech organizations can constantly improve the customer experience, because they’ll understand the behavioral traits and expectations of their clients. Effective Big Data analysis and financial data management help organizations to:

  • Provide personalized services. This includes long-time personalization, which is based on forecasting the customers’ needs; real-time personalization, which means offering recommendations and services based on previous customer experience; and personalization of communication through bots and the customer’s communication history.
  • Carry out customer segmentation. This means dividing customers into groups based on certain characteristics, such as gender, age, location, industry, job type, and others. Categorizing customers this way allows financial organizations to offer relevant services to their clients, provide special loan terms and other bonuses, and increase customer loyalty.
  • Improve the quality of customer support. With the help of Big Data, financial organizations can arrange multichannel support through phone calls, emails, social media platforms, chatbots, and other means of communication. This leads to a faster response to reported issues and creates the image of a company that takes care of its clients.
  • Comply with standards. Big Data analysis helps organizations successfully pass frequent audits and certifications that are common in the fintech industry. In this way, customers are ensured that they are dealing with trustworthy financial partners.

We can see the positive impact of Big Data on the customer experience. But the positive effect of Data Science on businesses doesn’t end there.

How Do Financial Businesses Benefit from Data Science?

Another field where financial organizations can benefit from using Data Science is in improving internal corporate processes. Businesses can do this in several ways.

Advantages of Data Science for financial businesses

Identifying new opportunities

Using analytical tools can reveal new opportunities for a company’s growth and development. For example, using market data to analyze trends can help a business forecast whether it is profitable to enter a new geographical market.

Also, fintech Data Science can predict whether it is more cost-effective to invest in a new product or to improve an existing one.

Thus fintech data analytics helps in finding new opportunities, forecasting whether they will be profitable, and calculating when an organization can expect to see a return.

Increasing staff productivity

With the help of Data Science, organizations can assess which tasks take up most of their employees’ time and consider whether some of those processes can be automated.

For example, technologies can take simple but monotonous tasks off the hands of workers, leaving them free to devote time to more creative tasks, which will increase overall productivity.

Improving decision making

This is a very important aspect of using data analytics. Leveraging data effectively, organizations can make thoughtful decisions and build successful business strategies. Analytical tools can share data in real-time and provide organizations with timely feedback that they can act on.

Also, data scientists can create models to predict the outcome of a particular business decision. It helps managers consider various options, choose the best one, and create effective plans for achieving their business goals.

Increasing competitiveness

Data analytics in fintech is helpful in not only gathering data about customers but also in collecting data about competitors. Data Science tools allow for conducting effective competitor research that organizations use to make pricing decisions, enter new markets, and improve business strategies to stay one step ahead of the competition.

Optimizing allocation of resources

With Data Science, financial institutions can analyze which areas of operation should be developed first to achieve economic efficiency. That allows them to make optimal use of their resources, allocating them to the high-priority tasks first.

To sum up, fintech organizations benefit greatly from using Data Science, because it improves many areas of operation, from revealing new opportunities to making better-informed decision-making processes.
