Bank Connectivity: What ISO 20022 really solves and what it doesn’t

This article is written by our partner, Cobase

ISO 20022 was supposed to unify banking. It probably won’t.

Few projects in modern banking have carried as much expectation as ISO 20022.

For years, it has been described as the future language of global finance, a common standard that would finally allow banks, payment systems, corporates, and financial institutions to communicate in a structured, consistent way. Richer data. Better interoperability. Fewer errors. Faster processing.

After decades of fragmented formats and incompatible messaging systems, ISO 20022 arrived with something close to utopian ambitions: the idea that banking might finally start speaking the same language.

And in one important sense, it is already changing the industry.

The migration is enormous in scale. SWIFT cross-border payments, domestic RTGS systems, clearing infrastructures, and banks across major markets are moving from older MT messaging formats toward ISO 20022 XML-based messages.

The technical benefits are real.

Legacy payment messages were notoriously constrained. Fields were short, often unstructured, and inconsistently interpreted. Critical information – addresses, remittance details, compliance data was frequently truncated as payments moved across systems. ISO 20022 introduces far richer and more structured data models, improving straight-through processing, compliance screening, and automation.

In theory, this should reduce fragmentation.

In practice, the picture is more complicated.

Because ISO 20022 does not standardise banking behaviour. It standardises messaging.

That distinction matters.

Thy Cao quoteTwo banks can both be fully ISO 20022 compliant and still process the same payment differently. One may require additional fields. Another may reject optional data that a third bank accepts. One market infrastructure may implement a specific version of a message type, while another introduces local usage guidelines layered on top of the global standard.

The industry has already developed multiple “flavours” of ISO 20022:

  • CBPR+ for SWIFT cross-border payments
  • SEPA usage guidelines in Europe
  • domestic variants for markets like the UK, Switzerland, and the US
  • bank-specific implementation rules on top of all of them

So while the syntax becomes more aligned, the operational reality remains fragmented.

In many ways, ISO 20022 is repeating a familiar pattern in banking: harmonisation at the framework level, divergence at the implementation level.

SEPA followed a similar trajectory. It standardised payment schemes across Europe, but banks still implemented formats differently. Corporates discovered that “ISO compliant” did not necessarily mean “interchangeable.”

The same dynamic is emerging again.

And then there is the migration itself.

One of the lesser-discussed realities of ISO 20022 is that it does not replace the old world overnight. For years, legacy MT formats and ISO 20022 messages have coexisted across the global payment ecosystem. Translation layers became necessary. Data moved between old and new standards, sometimes losing structure along the way.

Even after formal migration deadlines pass, coexistence does not truly disappear. Banks continue running legacy infrastructure internally. Corporate ERP systems remain unevenly upgraded. Some channels fully support enriched ISO data, while others still rely on reduced mappings for compatibility.

The result is not a clean reset, but another layer added onto an already layered system.

This is particularly visible for corporates.

For treasury teams, ISO 20022 is often presented as a simplification initiative. In reality, it frequently increases short-term complexity. Payment files need updating. ERP integrations require modification. Validation rules become stricter. Banks introduce their own migration timelines and interpretation guides. A format that works with one bank may still require adjustments for another.

What changes is not the disappearance of complexity, but its shape.

This is where orchestration becomes increasingly important.

Platforms like Cobase sit between corporates and the banking ecosystem, absorbing many of these differences. Instead of treasury teams managing each bank’s ISO implementation directly, the orchestration layer handles format conversion, message enrichment, validation, and routing centrally.

A single payment instruction may need to be transformed differently depending on whether it is sent via SWIFT CBPR+, SEPA, EBICS, or a proprietary bank API. Structured address requirements may differ by market. Optional ISO fields in one implementation may become mandatory in another.

From the corporate perspective, the goal is not to master every variation of ISO 20022.

It is to operate through a layer where those variations are managed automatically.

That is ultimately the paradox of ISO 20022.

It absolutely improves the global financial system. The richer data, standardised structures, and interoperability gains are significant. It reduces friction. It improves automation. It creates a more modern foundation for payments infrastructure.

But it does not eliminate the deeper forces that created fragmentation in the first place:

national regulation, local market practices, bank-specific implementations, legacy infrastructure, and competing commercial incentives.

ISO 20022 may unify the language of banking. It will not fully unify the system speaking it.

Disconnected systems rarely fail all at once. That is what makes them difficult.

A bank portal still works. The ERP still produces data. A spreadsheet still calculates a forecast. A payment approval workflow still moves from one person to the next. Reports still reach the CFO, even if they arrive later than expected. From the outside, treasury appears to function. Inside the process, finance teams know exactly how much effort is required to keep that appearance of control intact.

Modern treasury cannot rely on disconnected systems because the questions it needs to answer are no longer isolated. Cash visibility depends on bank data, account structures, ERP information, payments in progress, forecast inputs, intercompany flows, financing activities, and exposures. Liquidity planning depends on operational data from the business, but also on treasury assumptions, market conditions, working capital movements, and funding plans. Risk management depends on reliable exposure data, but also on trade execution, hedge documentation, limits, reporting, and accounting. If each part of this picture sits in a different place, the treasury team becomes the integration layer.

The work behind the answer is too often invisible

That integration work rarely surfaces. It lives in copy-and-paste routines, manual file checks, email reminders, reconciliation notes, spreadsheet tabs, and individual memory. It is also where most treasury management challenges quietly begin.

Disconnected systems create time loss because data has to be gathered before it can be analysed. They create duplicated work because teams maintain local trackers even when central tools exist. They weaken cash visibility because the latest view may depend on which bank file has arrived or which entity has responded. They weaken controls because exceptions are harder to identify when workflows are not connected.

The CFO does not usually see the process friction. The CFO sees the answer. If the answer is late, inconsistent, or hard to explain, confidence falls. Senior leadership needs reliable responses to simple but high-stakes questions: How much liquidity is available? Which cash flows are expected? Where is working capital tied up? Are internal payments efficient? Which exposures are material? Are guarantees, hedges, and commitments under control? These questions cannot be answered well when the data behind them has to be rebuilt every time.

Fragmentation turns into a daily control problem

The 2026 Nomentia Treasury and Cash Management report highlights that many treasury teams are in a transitional phase. They have moved beyond purely manual treasury, but still rely on multiple systems and partial automation. The pattern is familiar: the organisation has invested in technology, yet treasury still spends too much time reconciling information and validating reports. The issue is not that systems are missing. The issue is that they are not connected enough to support the pace of decision-making.

Where disconnected systems create risk

Disconnected systems are especially risky in three areas.

The first is visibility. If cash positions, transactions, forecasts, and payment statuses are not consolidated, treasury may see parts of the picture but miss the direction of movement. A balance report can show where cash is today, but it does not explain whether the position is temporary, restricted, exposed, or needed elsewhere in the group. Visibility without context can create false comfort.

The second is control. Treasury policies often look clear on paper, but control depends on how processes actually run. Who can approve a payment? Which entities have followed the forecast process? Which exposures have been validated? Which guarantee is close to expiry? Which hedge relationship needs attention? When workflows are disconnected, control becomes dependent on manual follow-up. That may work when volumes are low, but it becomes unreliable as banks, entities, instruments, and reporting expectations increase.

The third is decision speed. In volatile markets, delayed answers are not neutral. A late forecast can affect funding decisions. A delayed exposure view can affect hedge timing. A slow payment status check can affect supplier confidence. A late view of guarantees or credit line usage can affect working capital decisions. Treasury does not need real-time data for every decision, but it does need enough connected information to avoid making decisions with yesterday’s understanding.

What a modern treasury management system should connect

A modern treasury management system should not be judged only by feature breadth. The more important question is how well it reduces the gaps between systems, data, workflow, and reporting. A strong setup connects bank information, ERP data, payment processes, cash forecasting, risk workflows, analytics, and audit trails into a reliable operating model. That does not mean every company needs every module at once. It means the architecture should support growth without forcing the team to rebuild its processes every time complexity increases.

Most people researching a TMS today will start with a web search or ask Copilot, Gemini, or ChatGPT. The answer they get back is usually a feature list. That’s not wrong, but it’s incomplete. A good treasury management system helps finance teams centralise cash, payments, forecasting, risk, controls, and reporting so they can make better liquidity and financial risk decisions with trusted data. Features are how it gets there. That’s the distinction worth keeping in mind when evaluating whether your current setup is still fit for purpose.

How to move away from disconnection without a major rebuild

The path away from disconnected systems does not always require a large replacement project. In many organisations, the better approach is to identify the most painful manual bridges first. Where does treasury re-enter data? Where does the team wait for local input? Where do reports need manual explanation? Where are approvals outside the system? Where is the same number calculated in different ways? These questions show where fragmentation is creating the most business risk.

Connected systems create reliable answers. They reduce the manual work behind cash visibility, improve the quality of cash flow forecasting, and support stronger controls and compliance. They help the CFO understand not only what the numbers are, but what they mean for liquidity, risk, and action. Disconnected systems may still function. But they make treasury work harder than it should, and confident decisions harder than they need to be.

In an increasingly complex financial environment, In-House Banks (IHBs) have emerged as a strategic imperative for corporations seeking enhanced cash visibility, optimized liquidity, and streamlined intercompany transactions. Drawing insights from a recent presentation by experts at Citi and seasoned treasurers, let’s explore what makes an IHB not just an option, but a cornerstone of modern treasury management.

What Is an In-House Bank?

An IHB is a centralized internal financial entity that manages cash, investments, foreign exchange exposures, and intercompany lending on behalf of corporate subsidiaries. Acting as a “virtual bank” for the organization, it reduces the volume of external banking transactions and provides critical advantages in cash management, governance, and compliance.

Importantly, an IHB is not a regional treasury center, shared service center, re-invoicing hub, or physical licensed bank. It’s a bespoke solution that integrates deeply with corporate finance operations.

Why Should Treasurers Prioritize an IHB?

An IHB addresses several core challenges that treasurers face:

  • Efficient Capital Structure: Reduces reliance on external debt and overdrafts.
  • Cost Reduction: Lowers bank fees and administrative costs.
  • Higher Investment Returns: Pools surplus funds to improve yields.
  • Enhanced Cash Visibility: Improves cash forecasting accuracy.
  • Governance & Automation: Strengthens controls and supports automation.
  • Tax Transparency & Compliance: Simplifies policy adherence across jurisdictions.

Core Functions and Value Propositions

Real-world IHB implementations, like those led by Brook Ballard at Oceaneering, showcase the tangible benefits:

Function and their Benefits:

  • Centralized Cash Management: Simplified account structures across currencies and entities.
  • Intercompany Lending & Borrowing: Optimized use of internal liquidity.
  • Payments on Behalf Of (POBO): Fewer operational accounts and streamlined reconciliations.
  • Aggregated Investments: Improved returns on pooled funds.

Intercompany netting further reduces payment transactions, bank fees, and FX costs by consolidating cross-border intercompany settlements.

Who Needs an IHB?

While beneficial for many, IHBs are particularly advantageous for:

  • Large Corporates: Organizations with revenue exceeding $2 billion typically benefit most.
  • Global Players: Firms with over 50% of revenue outside their home country.
  • Treasury-Savvy Firms: Companies with skilled treasury teams ready to harness the complexity of IHB operations.

Building a Successful IHB: Best Practices

  1. Knowledge & Expertise: Invest in skilled treasury professionals and leverage external advisory where necessary.
  2. Organizational Alignment: Secure executive sponsorship and cross-functional buy-in.
  3. Technology Infrastructure: Deploy a robust Treasury Management System (TMS) with ERP and bank integration.
  4. Resource & Project Management: Dedicate a capable team and adhere to structured project management practices.
  5. Policies & Procedures: Standardize loan agreements, approval processes, and operating procedures.
  6. Scalability: Start small and design for growth—build flexibility into liquidity structures, regional management, and technology solutions.

Key Takeaways

  • Do it right the first time: Poorly designed IHBs can create more problems than they solve.
  • Choose the right partners: Collaborate with technology and banking providers who understand your business.
  • Start early, scale smart: Even smaller enterprises should consider laying the groundwork for future IHB capabilities.

Final Thought

At TreasuryCube, we recognize that the modern treasury is not just about managing cash, it’s about unlocking strategic value. An effective IHB is a critical tool to help achieve that vision, especially when supported by integrated technology, skilled people, and proactive governance.

Key takeaways

  • Traditional fraud detection methods are no longer sufficient against today’s organized criminals, requiring finance leaders to shift from reactive responses to a proactive defense strategy.
  • Modern payment fraud prevention requires an integrated approach that combines AI-assisted anomaly detection, centralized payment hubs and strict validation protocols to stop attacks before they happen.
  • By treating fraud prevention as a strategic enabler rather than a compliance task, organizations can build the operational integrity needed to thrive in a complex financial landscape.

The reality of payment fraud has shifted from a question of whether an attack will occur to a growing likelihood of when and how it will occur.

For finance and treasury leaders, the strategies that provided a sense of security a few years ago may be insufficient against a new breed of sophisticated and relentless criminals. A 2024 survey from the Association for Financial Professionals underscored this reality, revealing that a staggering 79% of organizations were victims of payment fraud attacks or attempts.

This is not a distant risk: It’s an active, daily threat that demands a fundamental change in an institution’s defensive posture. The traditional, reactive approach – detecting and responding to fraud after it occurs – is, in many cases, no longer a viable strategy. The time has come to build a proactive defense.

How are fraudsters becoming more sophisticated?

Today’s fraudsters are often not lone actors but organized, well-funded operations that use advanced technology and psychological tactics. They study organizational structures, identify process gaps and exploit the path of least resistance.

Business email compromise remains a dominant method, where criminals impersonate executives or vendors with alarming authenticity to redirect funds. We’re also seeing the rise of AI-powered deep fakes, where a trusted voice on a conference call can be convincingly spoofed to authorize a fraudulent transfer.

These criminals understand that the entire payment lifecycle, from the initial onboarding of a vendor to the final reconciliation, presents a landscape of opportunity. They target the seams in your processes, exploiting the very human desire for efficiency and speed. This “disharmony,” a term coined by a FIS® and Oxford Economics study, captures the friction between the drive for growth and the drag of persistent security threats.

According to the study, 75% of C-suite executives identify fraud as a critical challenge.

Why is proactive fraud prevention critical for payment security?

How can organizations overcome the evolving threat of fraud? The answer lies in shifting from a fragmented, manual and reactive stance to an integrated, automated and proactive one.

A truly effective defense begins by fortifying the most common entry points. The vendor master file, for instance, is the heart of the payables process and a prime target. A single fraudulent change to a supplier’s bank details can lead to catastrophic losses before anyone realizes an error has occurred.

Overcoming this type of threat typically requires more than just diligence: It often demands a standardized, technology-enforced process. It includes implementing out-of-band verification, such as a phone call to a preverified contact, for any change to payment instructions. It means moving beyond trust and implementing strict, automated validation protocols.

What role does technology play in proactive fraud defense?

As transaction volumes grow, manual reviews can become an impossible bottleneck, creating the very noise that criminals use to hide their illicit activities. This is where modern solutions like AI-assisted anomaly detection become increasingly indispensable.

Unlike static, rule-based systems that can only catch what they are programmed to look for, AI and machine learning establish a baseline of “normal” payment behavior for each vendor and transaction type. These systems operate in real time, analyzing payments for subtle deviations in amount, frequency or timing that would be difficult for the human eye to detect. When an anomaly is detected, the payment is automatically flagged for investigation before it leaves the organization. This preemptive capability is a game changer.

How does centralizing payments improve control?

Organizations can achieve a greater level of control by consolidating their payment flows through a centralized payment hub. Instead of managing disparate security protocols across multiple ERPs and bank portals, a payment hub provides a more unified point of visibility and control.

A payment hub enables the consistent application of security policies, approval workflows and fraud detection analytics across the entire enterprise. It standardizes an institution’s defense, creating a fortress rather than a series of disconnected fences. A payment hub integrated with a third-party account validation service provides another critical layer, confirming that a beneficiary’s name matches their account information before a payment is ever initiated.

What does a future-ready fraud defense look like?

The path forward for finance and treasury leaders requires a strategic pivot. It means recognizing that fraud prevention is not merely a compliance checkbox but a strategic enabler of business resilience and growth.

Building a proactive defense involves a holistic approach that integrates advanced technology, standardized processes and a culture of vigilant verification. By embracing AI-driven monitoring, centralizing payment operations and empowering employees with specialized training, you can transform your security posture from reactive to preemptive.

This shift does not just mitigate risk: It builds the confidence and operational integrity necessary to thrive in a complex financial world.
