Question Answered: How to set up an in-house bank

Published: May 2025

“What is the best practice when setting up an in-house bank?”

Integrating an in-house bank is a complex process. Treasury Today interviewees counsel on the importance of striking a balance between automation with human expertise, and a phased approach. Support from all levels of the organisation and a dedicated IT team are also key to getting to grips with the most challenging elements of the process like regulatory compliance and the required technology infrastructure.

Roche integrated an in-house bank (IHB) more than two decades ago to establish a centralised treasury function, optimising cash and liquidity management across the group.

By implementing the IHB as the sole communicator with banks for the Roche Group, treasury was able to generate efficiencies through automation and transparency in intercompany payments because they are now settled internally rather than via commercial banks, reducing transaction costs and processing times.

The IHB consolidates FX exposures and allows for centralised hedging, reducing volatility and optimising risk management and we reduced counterparty risk by optimising the number of bank relationships and bank accounts. This also helped streamline cash management activities including treasury payments, overall bank communication and product selection and boosted our ability to negotiate with our banks.

Some of the key lessons we learnt include the need to balance automation with human expertise. While technology plays a crucial role in treasury transformation, skilled professionals remain essential for interpreting data, making strategic decisions and managing stakeholders and their exceptions.

A phased approach to transformation is also important. The IHB was gradually expanded in its early phase rather than implemented all at once, allowing for testing, learning and refinement. A dedicated Treasury IT team was one of many key success factors too. We established an eye-to-eye partnership with IT, Shared Services, banking partners, and internal finance teams, which contributed to the successful output of the IHB implementation. IT played a key role in integrating systems, while bank partners provided strategic insights and operational support.

A new implementation must either replace something existing to something better or truly add value in order to be justified. An IHB not only replaces decentralised banking structures with a more streamlined, efficient treasury model but also creates a positive impact by improving cash visibility, enhancing FX risk management and optimising banking relationships.

If a company operates in multiple markets, with multiple bank relationships, accounts and decentralised treasury management, an IHB can be a game-changer. However, organisations must ensure they have the right infrastructure, expertise and regulatory framework in place before implementation. Indicators or processes to look for the value add could be multiple international subsidiaries, where intercompany transactions are frequent or significant foreign exchange exposure, requiring centralised risk management. Multiple bank relationships in the same region or even country and trapped cash are also driving factors.

The centralisation of processes with an IHB and a dedicated team enable faster responses to changing environments, generate value for the business, and ensure alignment with global corporate guidelines while enhancing overall efficiency. Companies can take their IHB to the next level by expanding treasury solutions, automating processes for greater efficiency, and ensuring agility in response to geopolitical changes, regulations and economic uncertainty.

In-house banking has emerged as a strategic enabler for modern treasury functions. By centralising cash management, corporates can achieve improved visibility, cost savings and tighter control over liquidity. While setting up an IHB can be complex, particularly from a regulatory and technological standpoint, starting with foundational elements like a centralised payment hub and real-time cash visibility lays the groundwork for broader treasury transformation.

But there must be rational considerations behind taking the decision to implement in-house banking. It is not a fit for most organisations, especially the ones that lack group structures.

Elements of in-house banking that are relatively straightforward include cash pooling and centralised payment processing. Many treasury software solutions offer well-established tools for pooling cash and automating payments. This centralisation quickly reduces transaction fees and improves cash visibility. When properly documented, intercompany loans lead to immediate cost savings by reducing external borrowing. Basic FX management is also straightforward.

More challenging elements to the process include regulatory compliance. For example, operating across multiple jurisdictions can be intricate. Each country may have distinct rules on intercompany lending, cash pooling and currency controls. Staying compliant requires constant monitoring of international regulations.

Setting up the technology infrastructure – integrating enterprise resource planning (ERP) systems, TMS, and bank portals – can be demanding, as can navigating tax and transfer pricing. Intercompany transactions must align with local tax rules. IHBs also need robust transfer pricing policies and documentation to avoid regulatory pitfalls.

A practical starting point is cash visibility. By consolidating daily bank statements and balances into one centralised view, treasury can accurately gauge the company’s overall liquidity. The process involves standardising payment processes, implementing a cash pooling structure and automating intercompany settlements. Once payment processes and cash pooling are in place, move on to more sophisticated intercompany financing arrangements, such as internal loans and netting.

It’s possible to navigate regulatory hurdles by appointing a dedicated compliance resource or external advisor to stay on top of evolving regulations. Each intercompany agreement must be carefully documented to satisfy local authorities. It’s also possible to overcome technological complexity by investing in a treasury management system (TMS) that integrates with your existing ERP and global bank accounts. Ensure it can scale as the company adds new subsidiaries or market regions. The best way to manage organisational change is to communicate the benefits – lower financing costs, improved liquidity, better FX rates – and involve local finance teams early.

Building an IHB is not just a technology rollout. Success depends on aligning stakeholders, managing change and embedding the function into day-to-day operations. Based on industry experience and real-world implementations, the following ten best practices can help organisations structure a successful in-house banking journey:

  1. Implementing an IHB introduces new ways of working across group entities. It requires commitment from top leadership, a clear budget and defined responsibilities.

  2. Start with what delivers the most value fast: cash visibility, internal payments and centralised control. More advanced components like FX netting or working capital optimisation can follow once the foundation is in place. A phased approach enables quick wins and keeps the project manageable.

  3. Bring in the right expertise. Whether internal or external, domain-specific expertise in treasury, intercompany financing, legal structuring and system integration is critical.

  4. Prioritise legal, tax and compliance early. Ensure intercompany arrangements are properly documented, tax-compliant and at arm’s length. Standardised templates and policies reduce complexity while supporting audit readiness.

  5. Invest in project management. A successful IHB implementation requires coordination across business units, banks and functions. Dedicated project management ensures timelines stay on track, local teams stay engaged and expectations are aligned across the board.

  6. Define a blueprint and operating model. Before selecting a solution, clarify the end-to-end processes you want to support. Will the IHB act as a full internal bank or a payment hub? Define how you want to manage loans, interest calculations and reconciliations.

  7. Operate through a centralised hub. Whether using a hub-and-spoke or hybrid model, central coordination is essential. A central hub allows treasury to maintain control while enabling local flexibility.

  8. Choose scalable, treasury-ready technology. Opt for platforms that are modular, easy to implement, and proven to support both current and future treasury needs. Some organisations initially focus on bank connectivity and payments, then scale to include intercompany loans, cash pooling and forecasting, without needing external consultants or reconfigurations.

  9. Embed the IHB operationally. Treat the IHB not just as a system but as a service. Define clear service levels, assign responsibility, and ensure subsidiaries know where to go for support.

  10. Continuously evaluate, learn and improve. Once live, regularly review the IHB’s performance. Use feedback from local entities to enhance usability, reduce friction and ensure the platform continues to meet evolving business needs. Celebrate successes and share them internally to maintain momentum.
