Legacy trade reconciliation is failing you – here’s how to fix it

Trade reconciliation should be the bedrock of your control framework. Yet, for many Operations leaders, processes that should be automated are still painfully manual.

This is because traditional automation tools are rigid and outdated. They can’t handle the complexity or volume of modern financial data and are slow and difficult to change.

Teams often resort to Excel spreadsheets and other forms of end-user computing (EUCs) in order to keep pace with the demands of the business.

The result? Many banks, asset managers and sell-side firms have thousands of Operations workers, running hundreds or thousands of manual processes, at a cost of $millions.

There is a better way. Modern data automation moves beyond simple matching to deliver true straight-through processing (STP).

By leveraging AI and cloud-native technology, you can eliminate the manual drag on your teams and increase efficiency. 

This isn't just about fixing breaks; it’s about empowering your Operations to move as fast as the market.

Let’s explore why traditional approaches to trade reconciliation automation are failing, the downsides of compensating with manual work, and the new technology and approaches offering a path to full automation.

What is trade reconciliation – and why is it under pressure?

Trade reconciliation is the process of comparing your internal trade records against external sources. For example, counterparty confirmations, custodian reports, and clearing house data. The goal: to ensure that all versions of the same data are accurate and up-to-date, and to flag discrepancies.

Why reconciliation exists (and why it matters)

You reconcile trades for four critical reasons:

  1. Preventing trade failure: Reconciling affirmations and confirmations ensures that the trade economics matches what was agreed with your counterparty. Getting this wrong risks trade failure.
  2. Ensuring regulatory compliance: Regulators demand accurate books and records with full transparency into positions, exposures and contingent obligations.
  3. Identifying and managing risk: Reconciliation allows you to spot errors before they can cascade into incorrect margin calls, bad collateral calculations, and settlement fails.
  4. Maintaining operational integrity: Catching breaks early prevents rework cycles, maintains client trust, and protects P&L accuracy.

All this ensures the integrity of your data – a foundational requirement for banks, brokers, asset managers, hedge funds and administrators.

The post-trade reconciliation process: How it works (in theory)

The trade reconciliation process follows a pattern:

  1. Ingest data from your order management systems, execution platforms, and booking engines.
  2. For internal reconciliations, compare datasets from different systems, such as internal books of records (IBOR) and accounting books of records (ABOR) or order management systems (OMS) and settlement/clearing systems. For external reconciliations, compare the data against external confirmations from counterparties, custodians, and clearing counter parties (CCPs).
  3. Flag the exceptions where records don't align.

Then investigate. Is it a timing mismatch? A data entry error? A genuine trade dispute? Operations teams look into all this to determine root cause and resolve the break before settlement.

The challenge: doing this at scale, in real-time, across multiple asset classes, while maintaining complete audit trails.

It’s a gargantuan task that most firms are still grappling with.

Growing complexity in capital markets: Volume, speed, new assets

The pressure on trade reconciliation is increasing from multiple fronts.

T+1 settlement has compressed timeframes. Most firms are using overnight batch processing, due to the limitations of their legacy technology. This means Operations teams don’t discover exceptions and errors until the morning of T+1 – which is now just hours before the trade needs to settle. Instead, firms need to be able to reconcile their data on trade date (T0).

Data volumes have exploded. High-frequency trading breaks single orders into hundreds of smaller executions. A $100,000 trade that once generated one reconciliation record now creates 100 separate data points. Legacy systems can't keep up.

New asset classes multiply complexity. Tokenised assets require you to reconcile both traditional securities and their blockchain representations. It effectively doubles reconciliation workloads. Cross-asset portfolios spanning derivatives, crypto, FX and private credit each bring unique data schemas and matching requirements.

Enterprise firms manage multiple systems. This fragmentation creates data siloes, inconsistent exception management, and drains your subject matter experts, who must context-switch between systems all day.

Geopolitical volatility drives volumes higher. Market turbulence means more trading. More trading means more reconciliations. Your already-stretched Operations teams face even more pressure.

Regulators have upgraded their surveillance. Authorities now use AI-powered tools to interrogate millions of trade reports. They spot patterns your legacy reconciliation systems can't detect. The gap between regulatory capability and your firm's readiness keeps widening.

Why legacy reconciliation tools are breaking

Legacy reconciliation platforms weren't built for today's markets. They can't handle the volume, can't process in real-time, and can't adapt fast enough. They are highly technical, meaning Ops teams must hand over process creation and iteration to already overburdened IT teams.

This takes a long time, so teams often resort to spinning up end-user computing (EUC) solutions such as Excel spreadsheets. These manual workarounds compound operational risk and introduce complexity.

Additionally, incumbent reconciliation tools suffer from fundamental capability gaps. Their matching engines are based on ‘key’ fields. This binary approach means that even data pairs with a high correlation are often marked as exceptions because of differences in the few fields the algorithm is considering.

This generates a large number of false exceptions – data that has a clear counterpart, but the system can’t spot it. Operations teams waste lots of time correcting these basic errors, which get in the way of finding and resolving the real breaks.

The cost of on-premise trade reconciliation

While the shortcomings of on-premise legacy systems are many, escaping from them isn’t easy.

The economics trap you. Many of these systems have been in place for a decade or more. They have become a vital pillar in your architecture, albeit one supported by spreadsheets and other manual work. Replacing one on-premise system for another is a long and costly process; one that may not deliver any benefits.

But staying put doesn’t avoid all the costs. Many on-premise systems require mandatory upgrades – often yearly, often costing seven figures. Upgrades like this are the only way to deliver innovation in an on-premise world. But because many on-premise vendors customise their systems on a client-by-client basis, you’re left having to spend a huge chunk of your change budget on testing the new version to make sure it hasn’t broken any existing processes.

So changing systems in a legacy world can be expensive, but sticking with what you currently have isn’t better.

Manual workarounds to legacy shortcomings create operational risk

When rigid reconciliation platforms cannot adapt to new requirements or data types, they leave Operations teams with no choice but to bridge the functionality gap with manual processes. Keeping the lights on means exporting data to Excel and other forms of end-user computing (EUC).

But spreadsheets are a brittle foundation for critical controls. Forcing enterprise data into spreadsheets introduces unavoidable operational risk. Excel was not designed for high-volume reconciliation; it lacks the necessary governance frameworks. Macros are inherently fragile and prone to breaking, requiring constant maintenance that drains technical resources. Furthermore, spreadsheets offer no native audit trail. There is no systematic way to track who changed a formula or when, leaving the control environment opaque.

Indeed, complex macros often rely entirely on the logic of the specific individual who built them. This creates a single point of failure: if that person leaves the organisation, the understanding of the process leaves with them.

Rigid technology turns skilled analysts into data movers, preventing them from focusing their expertise on investigating breaks and resolving root causes.

The time and people cost of exception resolution

Finding data errors is only the first step of the trade reconciliation process. Discovering the root cause and fixing the data is essential. Unfortunately, legacy infrastructure frequently hinders this process, creating bottlenecks that turn routine breaks into complex investigations and slowing down the entire settlement lifecycle.

Fragmented workflows slow down collaboration

Legacy systems often focus solely on matching, leaving the critical workflow of exception management unsupported. This pushes resolution into disparate channels, such as email chains and circulating spreadsheets, rather than a centralised platform. In this environment, teams must manually discover who owns a specific exception type rather than relying on automated assignment.

Latency impacts settlement windows

Disconnected workflows drain valuable time through logistics. A break appearing at 9.00am may not reach the correct subject matter expert until the afternoon. This latency consumes time the team should spend on investigation. In a compressed settlement environment, these delays reduce the window for root cause analysis, increasing the risk of errors, settlement fails, and reporting gaps.

Manual handoffs introduce vulnerability

Relying on manual data movement creates vulnerability at every touchpoint. When systems require analysts to copy-paste exception data between tools, draft email summaries, or update offline trackers, transcription errors naturally rise. Simple issues, such as transposed Trade IDs or incorrect amounts, occur simply because the platforms do not speak to one another.

The rigidity of code-based automation

Even traditional automation solutions often struggle to solve these challenges. Because they rely on hard-coded logic, updating reconciliation rules to filter out false breaks can become a significant IT project, taking days or weeks. This rigidity often forces Operations teams to choose the immediate flexibility of spreadsheets over the slow turnaround of code-based changes.

Regulators are upgrading their technology faster

Financial regulators are modernising their surveillance capabilities faster than most financial institutions are modernising their controls. Authorities use AI and advanced analytics to interrogate millions of trade reports. They identify patterns your legacy trade reconciliation tools can't detect.

Audit trails in legacy systems are fragmented or nonexistent. It’s a lot of work to provide evidence of reconciliation controls to internal or external auditors. Operations teams have to compile reports from multiple sources, stitching together screenshots, Excel exports and email trails. The process takes days and raises questions about the robustness of such a control framework.

The total cost of ownership includes this audit burden. You pay external auditors to validate that your material controls meet quality standards. You pay business analysts to document complex configurations. You pay IT teams to maintain aging platforms. These costs dwarf the software licensing fees.

When reporting requirements change - e.g. new transaction reporting regimes, clearing rules, settlement standards - legacy tools and workflows adapt slowly. On-premise platforms require formal upgrade cycles. You choose between operating on outdated rules (risking compliance failures) or initiating costly change programs.

Black-box configurations obscure key operational knowledge

Understanding how legacy reconciliation tools work requires detective work. The matching logic exists somewhere in code. Transformation rules live in configuration files. Exception routing depends on scripts written years ago by people who no longer work at the firm.

Teams struggle to troubleshoot issues in these conditions. Figuring out why a reconciliation produces unexpected results requires technical experts to examine code. Business users can't interrogate the configuration themselves, which means they can't validate that the reconciliation reflects their intended business logic.

Documentation is critical, but in such an environment it quickly becomes outdated. Written procedures simply can’t keep up with the pace of configuration changes.

Ultimately, this means that knowledge becomes concentrated among a few senior team members who understand how everything connects. When they take vacation, processes slow down. When they leave, capability evaporates. You can't modify your own reconciliation controls without external consultants.

The struggle to retain talent in a world of manual work

Operations professionals are highly skilled. They have ideas for improvements; they see inefficiencies; they know the top challenges and probably have solutions in mind.

But legacy tools prevent them from implementing change. Instead, they must spend hours of their days performing repetitive manual tasks to compensate for automation gaps in the technology stack.

This capability gap drives talent away from financial services. Skilled analysts leave for other industries where they can apply entrepreneurial thinking. Offshore teams face the same motivation challenges - smart graduates in Mumbai or Manila also want meaningful work, not mundane tasks.

The problem compounds because the next generation of Operations talent expects modern tools and meaningful work. They want to harness the latest technology and make an impact on the organisation. This doesn’t happen in a world of spreadsheets, on-premise technology and a complex change management process that requires developers.

When frustrated staff depart, institutional knowledge walks out with them. The analyst who understood the nuances of OTC derivatives reconciliation takes that expertise to a competitor. The Operations manager who built counterparty relationships for break resolution moves to a startup with better technology.

What remains: a demoralised team managing infrastructure that can't be modernised, watching volumes and complexity grow while their tools stay stagnant.

Benefits of replacing legacy tech with full trade reconciliation automation

The manual work that exists in post-trade is compensating for the inflexibility of outdated legacy technology. Operational data automation platforms take a different approach - one that removes challenges around ingesting different data formats, matches data to a much greater accuracy and provides robust exception workflow capabilities.

This enables you to replace manual processes with automated controls, process transactions in real-time, maintain complete audit trails and adapt to changing requirements without the need to burden IT.

Trade reconciliation done differently

So far, we’ve explored the ways that legacy technology creates operational challenges. Now, let’s have a look at how the features of modern data automation platforms mitigate or avoid these challenges, and the benefits this brings.

First of all, automated ingestion eliminates manual file handling. Systems connect directly to source platforms, pulling trade data continuously rather than overnight. This enables T0 controls – you can identify and resolve breaks on trade date, before they cascade into settlement failures.

Instead of key-based matching, data automation platforms like Duco use a proprietary algorithm that compares all data, rather than select fields. This means that they can provide the best possible match for data instead of small differences, like formatting, timestamp variations, or field transpositions creating false breaks. Match rates therefore improve dramatically.

And where there are exceptions, handling them becomes systematic. Automated labeling categorises breaks by type – missing trades, amount mismatches, static data errors, timing differences, and so on. Each category routes to the appropriate resolver automatically. No more email chains deciding who should investigate.

Automating formerly manual processes removes the risk of human error when manipulating data. Error rates decline when Operations teams don’t have to copy data between systems, there aren’t any spreadsheets with incorrect formulae, and no one is relying on email summaries full of typos. The system maintains data integrity throughout the trade reconciliation lifecycle.

Replacing those processes with automated controls on a single platform also gives you much greater insight. Dashboards provide visibility that manual processes can't match. You see match rates day-by-day and week-by-week. Operations leaders can spot trends, such as deteriorating data quality from upstream systems, before it becomes critical. They can track resolution times and identify bottlenecks.

When files arrive late from source systems, automation makes it visible immediately. Teams see which feeds missed cutoff. They understand how delays impact completeness. This transparency enables proactive upstream fixes instead of reactive fire-fighting.

No-code process creation – for agile, governed Operations

No-code configuration enables business users in Operations teams to define matching logic, transformation rules, and exception workflows themselves. Changes can happen in hours, not months, and every action is governed and documented.

This transforms the operational analyst role. Subject matter experts apply their process knowledge directly to configuration. They test changes in sandboxed environments. They implement improvements without having to wait for overburdened IT teams to work through their backlog.

The entrepreneurial professional can finally contribute. They identify process inefficiencies and fix them, or spot patterns in exceptions and create automated handling rules. They can collaborate with stakeholders to refine requirements without technical intermediaries.

IT burden decreases. Technology teams aren't fielding constant reconciliation change requests, debugging Excel macros, or maintaining custom scripts. They focus on infrastructure, integration and control, while business users manage reconciliation logic.

This agility becomes especially valuable during volatile periods. When trading spikes, new products launch, or regulatory requirements change, you need rapid reconciliation adjustments. No-code tools enable speed that traditional platforms can't match.

Capability stays in-house when staff turnover occurs. Because configuration is visual and documentable, knowledge transfer improves dramatically. New team members understand reconciliation logic by examining the configuration itself, not reading outdated procedural documentation.

Built-in audit trails turn proof of compliance into a click

Every action in automated platforms creates an auditable record. Who configured this reconciliation? When did they change matching tolerances? Who investigated this exception? What evidence supported resolution? The system captures everything automatically.

Compliance requests that took days now take minutes. When internal audit asks for evidence of control effectiveness over the past quarter, you generate comprehensive reports with a few clicks. The audit trail includes configuration history, match statistics, exception resolution details and user activity logs.

Governance embeds naturally. Unlike Excel macros that anyone can modify, automated platforms enforce approval workflows. Configuration changes require authorisation. Exception resolutions follow defined procedures. Policy violations trigger alerts.

External audit costs decline because evidence is readily available and trustworthy. Auditors don't question whether controls operated as described – the system provides complete proof. This reduces both audit hours and internal effort supporting requests.

Regulatory examinations become straightforward. When supervisors request demonstrations of post-trade reconciliation processes, you show comprehensive dashboards, detailed exception workflows, and complete audit histories. There are no gaps, and no missing documentation.

Transparency supports continuous improvement. Management can analyse reconciliation effectiveness across portfolios, asset classes, and counterparties. They identify systematic issues that manual processes would hide, and can allocate resources based on data, not intuition.

This rapid deployment eliminates the traditional backlog. Operations can respond quickly to changing business needs, whether that’s building controls for a new product or asset class, or integrating an acquired company.

True SaaS architecture for enterprise scale

Every client accesses the same continuously updated platform. No version fragmentation. New features deploy automatically, and scale expands elastically to handle volume spikes without capacity planning.

High-frequency trading volumes, complex derivatives, and multi-asset portfolios all process on unified infrastructure. Organisations consolidate their reconciliation technology stack from multiple fragmented tools to one comprehensive platform with complete interoperability.

Exception workflows that Operations teams own

Configurable exception management transforms break resolution from manual chaos to systematic workflow. Automated labelling categorises exceptions by type. Smart routing assigns breaks to appropriate resolvers based on patterns.

Complete resolution tracking provides visibility that spreadsheet processes can't match. Leaders see resolution times trending and investigate bottlenecks. They identify counterparties consistently submitting incorrect confirmations and address root causes.

Operations teams can modify workflow logic as business needs evolve. They create new exception categories, adjust routing rules, and refine resolution procedures without calling on overstretched IT teams. Analysts transform from passive button-pushers to active process improvers.

Compliance evidence generated automatically

Duco generates comprehensive audit evidence automatically. PDF configuration exports document exactly how reconciliations work – matching logic, transformation rules, tolerance thresholds. And because these are all created using plain English natural language commands, there’s no black-box mystery. Everyone from new team members and leadership to auditors can understand what a rule does and why.

Internal and external audit requests can be resolved in minutes. The platform provides complete activity histories, resolution evidence, and control effectiveness metrics through simple queries. Compliance teams access everything without Operations compiling reports manually.

AI that actually improves your Operations

Duco's AI capabilities extend beyond matching optimisation into intelligent exception handling. This augments human judgment rather than replacing it. Complex breaks still require expert investigation.

We partner with clients on broader AI strategies. As firms explore how artificial intelligence can transform middle and back office operations, reconciliation automation provides immediate value while building toward more ambitious goals.

From bottlenecks to breakthroughs: Time to rethink reconciliation

Legacy trade reconciliation tools are failing. T+1 settlement, exploding data volumes, new asset classes, intensifying regulatory scrutiny – these pressures expose the limitations of manual workarounds, batch processing, and fragmented platforms.

The opportunity extends beyond replacing aging technology. Firms modernising reconciliation unlock the operational capacity that is currently consumed by manual exception chasing. They retain talented staff who want meaningful work, and can respond to regulatory change faster than competitors stuck on legacy platforms.

Full automation transforms reconciliation from cost centre to competitive advantage. With modern platforms onboarding in hours and delivering value immediately, the barrier to transformation has never been lower.

Common questions about automated trade reconciliation

Can data automation platforms handle complex reconciliations like derivatives?

Yes. Automated platforms for handling operational data excel at complex, multi-dimensional matching. Configurable rules adapt to derivatives characteristics, such as multiple legs, payment schedules, and contingent obligations.

Major global banks use modern automated reconciliation specifically for their most complex problems. Options, swaps, structured products, and OTC derivatives all reconcile successfully. Data automation layers normalise disparate formats, and fuzzy matching handles the variations that confound legacy technology.

The "too complex for automation" objection usually reflects experience with rigid legacy tools, not modern automation capabilities.

Doesn't automation just shift the problem to IT?

No-code reconciliation tools specifically prevent IT dependency. Operations managers, middle-office analysts, and control specialists configure and modify reconciliations themselves using visual interfaces.

IT gets involved for initial system integrations. But once data feeds connect, business teams manage reconciliation logic independently. They adjust matching tolerances, add transformation rules, and optimise exception workflows without technical tickets.

This actually reduces IT burden. Technology teams stop supporting Excel macros, custom scripts, or legacy platform upgrades. They focus on strategic infrastructure and security, while business-users handle reconciliation operations.

What stops firms from adopting full reconciliation automation?

One of the biggest challenges is the way that legacy technology has shaped thinking around what’s possible. For many firms, manually processing data is just a fact of life. The belief that reconciliation systems must be on-premise, require hard-coded rules and process data slowly - even overnight - is well ingrained. Operations teams have had to put up with these limitations for a long time.

This also shapes how people view the process of automating those outstanding manual tasks. Leaders are used to long, costly and often fruitless transformation projects. They are understandably scarred by bad experiences from their past.

But one of the strengths of modern data automation platforms is that they are cloud-native and highly flexible. They easily integrate into existing tech stacks to plug the automation gaps currently handled by manual work. The scalability of the cloud isn’t just about going as big as possible; it enables you to start small, prove the value of reconciliation automation, and expand the scope of the project incrementally.

How does full reconciliation automation support regulatory compliance?

Automated platforms provide the transparency and control that regulators increasingly demand. Complete audit trails demonstrate control effectiveness. Real-time monitoring catches issues before they become reportable events. Configuration documentation proves governance.

You also have greater agility to respond to regulatory changes. The no-code nature of operational data automation platforms, combined with their flexible approach to data ingestion, allows you to quickly iterate on processes to reconcile more fields or meet new requirements. The speed of these platforms also enables faster reconciliation, such as T0 processes, meaning you stay in control even as settlement windows get tighter.

The gap between regulatory surveillance capabilities and firms’ controls is widening. Authorities use AI-powered analytics to scrutinise trade reporting. Firms using legacy reconciliation tools are already behind.

Automation brings your control capabilities forward to match regulatory expectations.
