In 2025, managing financial subsidiaries represents a major challenge for institutions juggling multiple entities, disparate systems, and complex regulatory constraints. In an environment where agility and cost reduction are crucial, multi-tenant core banking emerges as the revolutionary solution enabling the centralization of multiple subsidiary management on a single unified financing platform. This approach radically transforms how financial groups operate, offering a modern alternative to costly and rigid traditional architectures.

According to Accenture's latest report on banking trends, institutions that have modernized their infrastructure are recording an average 45% improvement in operational efficiency. This transformation no longer concerns only large international banks, but also specialized financing groups, leasing companies, and microfinance institutions seeking to optimize their multi-entity operations.

The Basikon platform perfectly illustrates this technological revolution. Thanks to its cloud-native multi-tenant architecture, it enables financial institutions to manage all their subsidiaries from a single infrastructure while maintaining the operational independence of each entity. This approach addresses the strategic challenges of 2025: cost reduction, accelerated time-to-market, and automated regulatory compliance.

The Challenges of Multi-Subsidiary Management in the Financial Sector

The Multiplication of Systems and Data Silos

The growth of financial groups traditionally comes with the multiplication of independent banking systems. Each subsidiary develops its own tools, creating technological silos that complicate the global vision and slow down strategic decision-making. This fragmentation generates considerable hidden costs and limits the group's innovation capacity.

The case of Arrawaj perfectly illustrates this problem. This Moroccan foundation managed two distinct entities with separate systems: Infosys' Finacle Core Banking for the Arrawaj Foundation and a proprietary tool for Maymouna Financial Services. This duality created duplicates, inconsistencies, and prevented optimal time-to-market for responding to regulatory changes in the sector.

The Explosion of Operational Costs

Maintaining multiple independent banking infrastructures generates exponential costs. Each system requires its own technical resources, maintenance teams, licenses, and security updates. According to data from the French Ministry of Economy, financial institutions can reduce their infrastructure costs by 30% to 40% by adopting modern centralized solutions.

This cost multiplication becomes particularly critical in a context where security incidents in the banking sector have increased by 300% in recent years. Each independent system represents an additional vulnerability point, multiplying risks and necessary security investments.

Consolidation and Unified Reporting Difficulties

Managing subsidiaries with disparate systems considerably complicates data consolidation and unified reporting production. Teams must juggle heterogeneous data formats, different closing schedules, and non-harmonized business repositories. This complexity slows decision-making and limits the group's global analysis capacity.

The absence of unified vision also prevents optimization of synergies between subsidiaries. Cross-selling opportunities, risk mutualization, or process rationalization remain unexploited due to lack of infrastructure allowing an integrated approach.

What is Multi-Tenant Core Banking and Why It's Revolutionary

Definition and Operating Principle

Multi-tenant core banking revolutionizes the traditional approach by allowing multiple entities (the "tenants") to share the same infrastructure while maintaining complete isolation of their data and processes. As perfectly explained in Geniusto's article on the future of multi-tenant banking, this approach resembles an apartment building where each tenant has their private space while sharing common infrastructure costs.

This architecture allows financial groups to deploy a unified platform capable of simultaneously serving multiple subsidiaries with specific needs. Each entity retains its identity, business processes, and regulatory compliance while benefiting from economies of scale and shared technological innovation.

Cloud-Native Architecture and Economic Advantages

The cloud-native architecture constitutes the technical foundation of modern multi-tenant core banking. This approach offers automatic scalability, near-permanent availability (99.99%), and significant infrastructure cost reduction. Unlike legacy on-premise systems, cloud-native solutions dynamically adapt to each subsidiary's load fluctuations.

The Basikon platform exemplifies this approach with its entirely cloud-native infrastructure based on MongoDB NoSQL. This architecture allows institutions to create new environments in seconds, facilitating the onboarding of new subsidiaries or deployment of new financial products.

Comparison with Traditional Approaches

Traditional multi-instance approaches require deploying a complete copy of the system for each subsidiary, multiplying costs and complexity. Conversely, multi-tenant shares infrastructure while maintaining data isolation. This fundamental difference generates substantial savings and drastically simplifies maintenance.

According to Oracle FLEXCUBE technical documentation, multi-tenant support enables application and data sharing, generating significant efficiencies in terms of resources and costs. This mutualization doesn't impact security or confidentiality, with each tenant remaining completely isolated from others.

The 5 Strategic Advantages of a Unified Platform

Drastic Infrastructure Cost Reduction

Adopting a multi-tenant infrastructure generates immediate and lasting savings. Resource mutualization allows infrastructure cost reduction of 30% to 40% on average, according to client feedback. This reduction concerns all aspects: software licenses, hardware maintenance, technical teams, and energy costs.

The case of Arrawaj concretely demonstrates these benefits. By replacing two distinct systems with the unified Basikon platform, this institution reduced its operational costs by 40% while significantly improving service quality. The migration of one million customers and four million banking operations was completed without service interruption.

Accelerated Time-to-Market for New Products

A unified financing platform radically transforms innovation capacity. As highlighted in Oliver Wyman's study on banking modernization, cloud-native solutions enable deploying new functionalities in days rather than months, considerably accelerating time-to-market.

This agility becomes crucial in a competitive environment where reaction speed often determines commercial success. Subsidiaries can now simultaneously launch new financial products, benefiting from developments made for the entire group while preserving their business specificities.

Centralized Security and Compliance

Centralizing security on a multi-tenant platform paradoxically strengthens each subsidiary's protection. Instead of maintaining multiple security systems with variable protection levels, the unified approach allows implementing best practices homogeneously. The Basikon platform natively integrates multi-factor authentication, data encryption at rest and in transit, and a comprehensive access management system.

Automated regulatory compliance represents a major advantage in a complex regulatory environment. Compliance rule updates, whether PSD2, GDPR, or specific sector standards, are deployed simultaneously across all subsidiaries. This centralized approach drastically reduces non-compliance risks and associated audit costs.

Automatic Scalability According to Demand

The cloud-native architecture offers dynamic scalability that automatically adapts to each subsidiary's needs. During activity peaks, resources are automatically allocated, then released during quiet periods. This elasticity optimizes costs while guaranteeing consistent performance.

This adaptation capacity becomes particularly valuable during geographical expansions or new product launches. Subsidiaries can grow without technical constraints, with the platform automatically adapting to increased transactional volumes.

Simplified Partnership Management

A unified infrastructure considerably facilitates multi-subsidiary partnership management. Standardized APIs allow partners to connect once to access all group subsidiary services. This simplification accelerates partner onboarding and improves user experience.

The example of Calvin (formerly M3 Leasing) illustrates this capability. Thanks to the Basikon platform, this company easily connected to two major partner bank systems while offering white-label partner pages. This flexibility enabled accelerated commercial development in the Swiss market.

Technical Architecture and Key Features

Microservices and Modularity for Maximum Flexibility

The microservices architecture constitutes the technical core of modern multi-tenant platforms. This approach decomposes banking functionalities into independent services that can be developed, deployed, and updated separately for each subsidiary. Unlike traditional monolithic systems, this modularity allows fine customization without impacting other group entities.

The Basikon platform fully exploits this modular architecture. Each subsidiary can select and configure only the modules it needs, creating a customized solution that precisely meets its business requirements. This flexibility proves particularly valuable in a multi-entity environment where needs can vary significantly.

As demonstrated in Basikon's article on modern banking system innovations, this modular approach also facilitates emerging technology integration. Subsidiaries can progressively adopt new functionalities like blockchain or artificial intelligence without disrupting existing operations.

Open APIs and Seamless Integrations
