Key insights from DataArt's webinar on modernizing capital markets infrastructure.
The AI team needs six months of trading data to test a new risk model. The data exists but sits across three cloud environments in incompatible formats. By the time IT harmonizes sources and builds pipelines, the business need has already evolved.
This pattern is typical across capital markets firms. Data modernization projects stretch into their second year, while competitors deploy AI-driven features into production. The growing gap between data availability and data usability has become a direct competitive liability.
For years, the traditional response was large-scale integration projects: $20 million exercises in which stakeholders were locked in rooms until they aligned on data definitions. That model breaks down when the business question shifts every quarter and speed matters.

The Hidden Cost of Traditional Integration
Capital markets firms’ data evolved through acquisitions, regulatory responses, and business line expansions. Derivatives desks, equities teams, and fixed income groups often operate on separate technology stacks. Each merger added another system to maintain.
Organizational reality adds another layer of complexity. Sales teams view clients as revenue potential. Finance tracks billable delivery. Risk monitors exposure. Compliance needs the full picture. These groups were never designed to operate on a shared data foundation.
The historical fix was centralization: extract everything into a data warehouse, standardize definitions, and build ETL pipelines. Firms spent years mapping fields and debating which "customer ID" should become the golden record.
The traditional centralization techniques take so much time. It probably puts you out of the race if you were to chase this nirvana of having all of your data available for AI, because the speed you can centralize things is slow compared to what you want to use all this data for.
When speed matters, this approach collapses. Competitors launch new products while you're still in month eight of a cross-system integration project. A prime broker trying to analyze margin requirements across counterparties discovers that even basic queries require custom ETL work from a backlogged central team.
While the system grows, data consistency becomes a concern. Inconsistent data and complex pipelines delay the delivery of reliable analytics. They undermine business agility.
Slower analytics creates downstream problems. By the time models reach production, assumptions are outdated, and trust in the data has already eroded.
Why Federated Metadata Changed the Equation
Over the past six years, data architecture has shifted away from physical centralization. Instead of moving everything into one place, firms’ modern approach now focuses on connecting distributed data through flexible metadata frameworks.
Graph databases and semantic layers now enable firms to map relationships between data assets without relocating the underlying information. Trading systems can remain in their native environments while being discoverable and usable alongside client CRM data and risk calculations in separate analytics platforms.
Modern metadata tools also support flexible schemas. Data models no longer need to be rigid, difficult-to-evolve relational database schemas fixed in SQL Server. This flexibility allows firms to adapt as business requirements change.
The operational impact is significant. When a prime broker needs to analyze margin requirements across counterparties, teams no longer need to wait for new ETL pipelines to be built. The metadata layer provides the connective tissue to query across systems, while business teams maintain ownership of their source data.
Modern metadata catalogs also improve visibility into governance. Automated data lineage tracking shows exactly where each data element originated and how it transformed through various pipelines. Tools such as Unity Catalog and Open Metadata emerged as leading options, with firms choosing between tighter cloud integration or greater platform flexibility.
The architectural shift also addresses a persistent governance problem: who actually owns customer data when 11 different departments access it? Federated models also clarify data ownership. Central IT maintains the technical infrastructure. Business units control access policies and quality standards for their domains. This separation resolves long-standing conflicts over accountability.
Platform Choices and Their Trade-offs
Serverless architectures and cloud-native tools lowered the barrier to building data pipelines. A small team can spin up infrastructure in days rather than months. But speed introduces new questions about standardization.
AWS Glue provides flexibility for custom transformations. Databricks offers more opinionated workflows with built-in governance. Firms moving between platforms often discover that initial flexibility came at the cost of long-term operational complexity. The decision hinges on whether standardization helps or limits specific use cases.
Out-of-the-box functionality reduces the need for custom connectors and manual upkeep, freeing teams to focus on business-relevant tasks rather than infrastructure maintenance.
But standardized platforms impose assumptions about data workflows. A market data provider processing tick data has different requirements than an asset manager running monthly risk reports. Generic tools optimize for common patterns rather than specialized needs.
Cost models also differ. Pre-built solutions from Moody's or Oracle bundle data content with platform capabilities. Cloud-native tools separate those costs, but require stronger in-house technical expertise. Larger firms often prefer control. Smaller organizations prioritize faster time-to-value.
What Actually Needs Central Governance
Many organizations struggle with the trade-off between centralization and federation. Some attempt to push all data ownership to business units, only to discover that trading desks lack the technical capacity to manage data quality frameworks or maintain security policies.
We as IT departments should always remember that the work we do, we don't do it to provide just some technical upgrades for the sake of having technical upgrades. We should be very careful with business needs, we should get the requirements, we should understand the flows.
The reality is that business units often don't have the skills or capacity to handle technical data operations. In practice, data or IT teams provide services under the ownership of different business units, helping them build and maintain data products while respecting domain ownership boundaries.
Central governance should establish standards around security policies, access controls, and quality thresholds. What constitutes acceptable data freshness? How do teams handle PII in development environments? Which data assets require regulatory audit trails?
Business leaders need to make these risk decisions, then enforce them through technical controls.
The platform team provides the tools: automated quality checks, policy enforcement through metadata layers, and lineage tracking for compliance reporting. Business units use these tools to manage their domains, but they don't build the underlying infrastructure from scratch.
This model requires clear ownership boundaries. When a data quality issue surfaces in a risk report, responsibility must be traceable.
Successful implementations document these handoff points explicitly and staff central data teams with professionals who can translate between business requirements and technical capabilities.
Starting Small Without Creating Lock-In
Modernization does not require organization-wide transformation on day one. Focused pilots around high-impact use cases, such as credit risk modeling or client onboarding analytics, allow teams to prove value quickly.
Effective starting points follow a simple sequence:
- Identify a business-critical domain
- Catalog existing data assets
- Map lineage for one core metric
- Build metadata connections before consolidating storage
Open standards matter here. Apache Iceberg and Delta Lake formats ensure that data assets remain portable as platforms evolve, reducing future mitigation risk. Organizations that lock into proprietary formats often discover later that migration costs eliminate the flexibility that modern architectures provide.
Targeted adoption also accelerates cultural buy-in. When one desk demonstrates measurable improvement, adoption spreads through results rather than executive mandates.
The firms making progress combine technical depth with domain expertise. A talented data engineer who's never worked with margin calculations or settlement processes will struggle to prioritize meaningful integrations. Similarly, a domain expert without technical grounding can't evaluate architectural trade-offs. Progress depends on bridging that gap.
The Cost of Standing Still
The inflection point has passed. Modern data architecture is no longer a differentiator. Now, not having it creates a competitive disadvantage.
Firms that delay modernization face growing integration friction, slower product delivery, and reduced analytical reliability. The competitive gap widens each quarter.
Speed now belongs to organizations that stop chasing perfect centralization and start building flexible, connected data foundations.
Start by identifying which business capabilities are currently blocked by integration friction, then address those gaps before competitors do. Pick one domain that matters to revenue or risk. Catalog the data. Map the lineage. Prove the value. Scale from there.
