Monzo & Google Cloud: Data Analytics Revolutionising Banking

In the digital age, data has become the lifeblood of financial institutions. From traditional banks to cutting-edge fintechs, the ability to collect, analyse and act on vast amounts of information is crucial for success. This is particularly true for challenger banks, which rely on data-driven insights to offer innovative services and compete with established players. These digital-first institutions harness the power of data to understand customer behaviour, streamline operations and develop personalised products. 

By leveraging advanced analytics and machine learning, challenger banks can make faster, more accurate decisions, enhance risk management, and provide superior customer experiences. As the financial landscape continues to evolve, the banks that can effectively utilise their data will be best positioned to thrive. One such institution leading the charge is Monzo, a UK-based digital bank that has partnered with Google Cloud to build a robust data analytics ecosystem.

Digital banks, or challenger banks, are becoming an ever more prominent feature of the financial landscape. Strictly digital, they use apps and online platforms to support their customers. Digital banks have an advantage in that they don’t rely on legacy systems. This allows them to be nimble, innovate at speed, and more proactive than many traditional banks. Today, Monzo is one of the most popular digital banks in the UK, with over nine million customers, making it the seventh-largest bank in the UK by customer numbers. 

Central to Monzo’s success is its strategic partnership with Google Cloud, which has been instrumental in creating a powerful data analytics hub that fuels the bank’s growth and enhances customer experiences.

Google Cloud empowering Monzo to make data-driven decisions

Since its inception in 2015, Monzo has been at the forefront of cloud adoption in the banking sector. As one of the first UK banks to be fully cloud-based, Monzo recognised early on the potential of cloud computing to drive innovation and agility. The collaboration with Google Cloud has been pivotal in building a high-performance data analysis infrastructure that empowers teams across the organisation to make data-driven decisions.

At the heart of Monzo's data strategy is Google Cloud’s BigQuery, a serverless and cost-effective enterprise data warehouse. With nearly 19 petabytes of data and more than 2,000 data models stored in BigQuery, Monzo can process and analyse massive datasets with unprecedented speed and efficiency. This capability allows the bank to run complex pipelines and data modelling tasks, surfacing detailed customer and business insights that drive innovation and improve services.

Suhail Patel, Senior Staff Engineer at Monzo, emphasises the importance of this data infrastructure: “We empower all of our engineers and technical staff with BigQuery data across the organisation. With BigQuery, we can have all the data we need to effectively make business-critical decisions and analyse the impact of complex incidents when something goes wrong. For us, this is like having a superpower.”

To make sense of this vast trove of data, Monzo employs Looker, a business intelligence and data visualisation tool that sits atop BigQuery. This combination allows teams to access, analyse, and act on up-to-date, multi-terabyte datasets in minutes. From tracking key diversity and inclusion goals to monitoring profitability, Looker democratises data access across the bank, ensuring that insights are available to those who need them most.

The power of Monzo's data analytics capabilities extends beyond internal operations. The bank leverages machine learning models, built and trained using Google Cloud's Vertex AI, to enhance various customer-facing features. These models play a crucial role in protecting customers from fraud, making lending decisions, and even experimenting with customer demand forecasting.

One of the most innovative applications of Monzo's data analytics prowess is in its lending products. By analysing vast amounts of customer data, the bank can make more informed decisions about credit applications, set appropriate credit limits, and determine interest rates. This data-driven approach not only helps Monzo manage risk more effectively but also allows it to offer more personalised and competitive financial products to its customers.

A commitment to data security and compliance

The partnership with Google Cloud also supports Monzo's commitment to data security and regulatory compliance. Together, they have developed a robust disaster recovery program that ensures continuous data synchronisation between cloud platforms. This setup allows Monzo to switch to a backup platform within seconds, maintaining uninterrupted service for customers even in the face of potential outages.

Moreover, Google Cloud's global presence and expertise in navigating complex banking regulations provide Monzo with a strategic advantage as it eyes international expansion. This support is crucial for building customer confidence and meeting the stringent requirements of financial regulators in various markets.

“We have grown with Google Cloud and we can integrate our data with its other solutions,” says Patel. “By being on top of Google Cloud, we’re prepared to bring more products and continue growing in the UK and beyond.” As Monzo continues its impressive growth trajectory, with recent funding potentially pushing its valuation to £4.1 billion, the partnership with Google Cloud remains a cornerstone of its strategy. 

"Since 2015 Google Cloud is proud to be a part of Monzo's journey to revolutionise banking through data-driven innovation,” comments Adrian Poole, Director, Digital Natives UKI, Google Cloud. “Our collaboration demonstrates the transformative power of cloud technologies in the financial services industry.”
