Building a Reliable Market Data Inventory

In our previous article, we highlighted three recurring patterns that drive unnecessary market data costs and compliance risks: phantom users, usage traps, and parallel procurement. While these issues appear unrelated, they often share the same root cause: the absence of a reliable market data inventory.

Many financial institutions are seeking greater control over market data costs and compliance. Most of them maintain contract files, vendor reports, or entitlement records. However, these are often fragmented across procurement, business units, technology teams, and market data functions. As a result, three basic questions need to be answered:

• What do we own?
• What may we use it for?
• What does the business
  actually need?

A reliable market data inventory answers all three questions. Without this foundation, optimization initiatives are difficult to prioritize and audit risks stay hidden.

Three Components of a Reliable Market Data Inventory

A market data inventory is more than a list of vendors and contracts. It should provide a clear view of contractual obligations, usage rights, and actual business consumption.

1. What You Own: Contract Baseline

The first step is creating a complete inventory of all market data agreements, addendums, and commercial terms.

In many organizations, contracts are spread across different departments, which makes total vendor spend, renewal obligations, and ownership responsibilities difficult to establish. This often leads to duplicated services and missed optimization opportunities.

A contract baseline should provide visibility into:

• Active agreements and addendums
• Commercial terms and renewal dates
• Vendor spend across business units
• Business ownership and budget responsibility

Ask yourself: Can your organization produce a complete overview of all market data contracts, renewals, owners, and spend without reconciling multiple sources? If not, your inventory is incomplete.

2. What You May Use: Usage Rights

Understanding what has been purchased is only part of the picture. Organizations must also understand what they are entitled to do with the data.

Vendor agreements differentiate between display usage, non-display usage, derived data, redistribution, and other licensing scenarios. At the inventory level, the goal is not a full legal
interpretation of every clause. It is enough clarity to see where restrictions apply, rights are unclear, and a deeper entitlement review is needed.

Yet many institutions lack such a structured view of these entitlements. A usage rights overview should map both user-level and technical entitlements while highlighting potential licensing
and audit risks.

Ask yourself: Could your organization demonstrate how its major data services are being used against contractual entitlements if a vendor audit started tomorrow?

3. What You Actually

Need: Business Demand

Market data inventories often reflect past purchasing decisions, not current business demand. Desks change, systems are retired, new use cases emerge, but the subscriptions stay. As a result, firms frequently pay for services that are underutilized while lacking visibility into future demand.

A structured assessment should evaluate:

• Historical and current usage patterns
• Entitlement utilization
• Business stakeholder requirements
• Internal versus external distribution needs
• Real-time versus delayed data requirements

The objective is not simply cost reduction. It is keeping market data investments aligned with business value.

Ask yourself: When did you last validate your market data environment against current business requirements rather than historical purchasing decisions?

Why These Components Must Be Connected

Many organizations have visibility into one or two of these areas. Few successfully connect all three.

Contract information without usage analysis cannot identify optimization opportunities. Usage reviews without licensing visibility cannot assess compliance risk. Business requirements alone cannot determine whether existing contracts already meet demand.

True transparency emerges when contractual obligations, usage rights, and business consumption are linked together within a single inventory.

The Foundation for Long-Term Control

A reliable market data inventory is not housekeeping. It is the foundation of effective market data governance.

With this foundation in place, firms can identify phantom users, close usage traps, and replace parallel procurement with evidence rather than assumptions. The next articles in this series build
on it: classifying entitlements and assigning end-to-end ownership of the market data function.
