RBI Master Direction 2026 on Unique Identifiers in Financial Markets – Complete Practical Overview

The Reserve Bank of India has issued the Master Direction – Reserve Bank of India (Unique Identifiers in Financial Markets) Directions, 2026, creating a single, consolidated framework for the use of two critical global identifiers in RBI-regulated markets:

  • Legal Entity Identifier (LEI) – to uniquely identify entities participating in financial transactions; and
  • Unique Transaction Identifier (UTI) – to uniquely tag individual OTC derivative transactions.

These Directions replace and supersede a series of earlier circulars and are issued under the powers conferred by section 45W read with section 45U of the Reserve Bank of India Act, 1934.

The framework is structured in two parts:

  1. Section A – Legal Entity Identifier (LEI)
    • Effective immediately; and
  2. Section B – Unique Transaction Identifier (UTI)
    • Effective from January 01, 2027.

This article restates the key requirements and implications for market participants in a simplified, compliance-focused manner.

Important: Any extracts of statutory provisions, case names, section numbers and RBI notification references must be read exactly as originally notified. This write‑up only explains the operative framework in plain language.
