Big Data in Banking Industry: How to overcome new challenges

Being in the Big Data industry for over 14 years has shown us how important it is for Banking Institutions to use the correct data sets. 

Consider that Banking institutions generate massive amounts of daily data through countless transactions, customer interactions, and even third-party sources. Well, Big Data analytics can help these institutions make better use of this data. 

In this article, we will explain the role of big data analytics in the banking industry, how it works, and the main benefits for the sector. We will also highlight real-life use cases of banking institutions already using Big Data and provide tips for a good implementation of data methodologies.


In this article we will explore:


Banking Sector: What to expect in 2023?

Considering some reports like ING’s Bank Outlook, we can expect that, as the banking industry navigates through 2023, it will face numerous challenges that will test its resilience. 

Higher rates and inflation: One of the biggest challenges is the impact of higher rates and high inflation on debtors’ ability to repay their loans. Corporate books are expected to drive provisions, but larger corporates are better positioned than SMEs (Which are likely to have less pricing power and limited access to funding channels).

Mortgages: According to experts, we can expect mortgages to remain robust despite the slowing of housing markets. But banks with a larger share of floating-rate loans may face more pressure on loan quality. 

On the other hand, banks with a higher share of fixed-rate mortgages will experience a slow movement in average lending rates.

Credit quality:  Non-performing loan ratios declined across countries in 2022, but loan quality is likely to weaken from current levels. Banks categorizing a higher share of their loans as Stage 2 loans point to a weakening credit quality in the future.
