RBI Introduces Secured Overnight Rupee Rate (SORR)

The Reserve Bank of India (RBI) has announced the development of the Secured Overnight Rupee Rate (SORR) as a new benchmark for the interest rate derivatives market, based on secured money market transactions like market repo and tri-party repo (TREPS). SORR, to be developed with support from Financial Benchmarks India Limited (FBIL), aims to offer a trade-based, robust, and manipulation-resistant benchmark that reflects real market dynamics, unlike the Mumbai Inter-Bank Offer Rate (MIBOR), which relies on polling data.

The initiative aligns with global best practices, such as the Secured Overnight Financing Rate (SOFR), and signals a shift toward transparency in India’s benchmark-setting methodology.

Shift from MIBOR to SORR

MIBOR Overview: MIBOR, in use since 1998, is a polled rate derived by averaging responses from market participants.

SORR’s Edge: SORR is based on actual secured transactions in the overnight repo market, covering 98% of overnight market activity, ensuring higher reliability and less susceptibility to manipulation.

Global Alignment: The methodology mirrors SOFR, introduced as an alternative to LIBOR, emphasizing global transparency standards.

Role of FBIL and Market Impact

Development Responsibility: FBIL will design and implement SORR following the MIBOR Committee’s recommendations and public feedback received by November 15, 2024.

Market Dynamics: While SORR adoption does not immediately impact markets, it sets the foundation for a credible and transparent interest rate benchmark for hedging derivatives.

Broader Implications for Financial Markets

Strengthening Hedging Instruments: SORR will serve as a more representative benchmark for interest rate derivatives, enhancing market stability.

Expanding Non-Resident Access: Gradual access to onshore Interest Rate Derivative (IRD) markets is proposed for purposes beyond hedging.

Robust Market Representation: By focusing on secured repo transactions rather than call money rates, SORR better captures overnight funding rates, aligning with global benchmarks and liquidity conditions.
