Benchmark Reform's Second Wave Targets the Data Itself

The great rate-benchmark transition taught regulators that reference data is infrastructure, and infrastructure gets supervised. The second wave of that lesson is arriving for the broader data layer: index construction, evaluated pricing, and the reference feeds that steer passive flows and margin models.

Supervisors are asking benchmark-style questions of data providers, about methodology governance, conflict management, and error correction, and the providers are professionalizing accordingly. Buy-side firms report diligence on data vendors that resembles diligence on counterparties, a category shift with fee implications.

The direction of travel is consolidation and formality: fewer, larger providers operating under documented governance, priced like the critical infrastructure they were all along. The market spent decades treating data as plumbing; the plumbing now has inspectors.
