In the ever-evolving landscape of Banking as a Service (BaaS), the promise of innovation is often accompanied by the formidable challenges posed by regulatory landscapes. As we venture beyond the basics of BaaS, it becomes imperative to navigate through the intricate web of regulations that govern the financial sector.

Regulatory challenges in BaaS are multifaceted, spanning compliance, data privacy, and security. The nature of BaaS, which involves the collaboration between traditional financial institutions and non-banking entities, creates a regulatory grey area that demands careful navigation.

One of the primary hurdles lies in meeting compliance standards set by various regulatory bodies. Traditional banks are subjected to stringent regulations, and when partnering with non-banking entities in a BaaS model, ensuring that these partners adhere to the same standards becomes crucial. This involves addressing issues such as Know Your Customer (KYC) requirements, Anti-Money Laundering (AML) regulations, and data protection laws.

Moreover, the cross-border nature of many BaaS collaborations adds an additional layer of complexity. Each jurisdiction may have its own set of rules, making it challenging to create a seamless and compliant experience for users across different regions.

According to Levvel data, the top three barriers listed by FinTechs currently considering BaaS are concerns about compliance, legal, or security; a lack of understanding of the products that are currently available; and worries about working with multiple providers. This highlights the critical need for effective strategies and solutions to overcome regulatory hurdles.

Introduction to Regulatory Technology (RegTech) as a Solution

As regulatory challenges continue to evolve, the financial industry has witnessed the rise of Regulatory Technology, or RegTech, as a powerful solution. RegTech involves the use of technology, including artificial intelligence, machine learning, and big data analytics, to streamline and automate regulatory compliance processes.

RegTech not only addresses the challenges posed by existing regulations but also anticipates and adapts to changes in the regulatory landscape. By leveraging advanced analytics, RegTech solutions can provide real-time monitoring, risk assessment, and compliance reporting, enabling financial institutions and BaaS providers to stay ahead of regulatory requirements.

A new study from Juniper Research has found that spending on Regtech, systems that enable banks and other heavily regulated sectors to meet their compliance burdens, will exceed $130 billion in 2025, from $33 billion in 2020. The report found that this 290% growth is being fuelled by greater use of AI to automate highly manual tasks, and the transition to digital onboarding, which have emerged as critical capabilities in the wake of the pandemic.

As we delve deeper into the complexities of BaaS, embracing RegTech becomes imperative. It not only enhances efficiency in compliance but also empowers organizations to proactively manage regulatory risks.
