Final LIBOR Transition Deadline: No New US$ LIBOR or MIFOR Contracts After June 30, 2023

Current · Source: Reserve Bank of India · RBI/2023-24/30 · issued 12 May 2023 · ~2 min read
Quick answerRBI mandates banks to stop all new US$ LIBOR and MIFOR-linked contracts immediately and complete fallback clause insertion in legacy contracts before June 30, 2023. Synthetic LIBOR cannot substitute fallbacks. Systems must be ready for full transition from July 1, 2023.
The rule, in the simplest words
How it plays out — a real example

A payments & clearing officer in Indore checks her bank's old loan contracts and finds one still using MIFOR. She quickly calls the customer to explain they need to sign an update that switches the rate to MMIFOR before June 30, 2023, so the loan doesn't get stuck without a rate after that date.

What changed

RBI reiterates that after June 30, 2023, publication of remaining five US$ LIBOR settings and MIFOR will cease permanently. Banks must ensure no new transactions reference US$ LIBOR or MIFOR, and complete fallback insertion in all legacy contracts. Synthetic LIBOR rates are not a valid substitute for fallbacks.

What it means for you

Banks and FIs face a hard deadline: any remaining US$ LIBOR or MIFOR-linked contracts without fallbacks will become unanchored after June 30, 2023. This could lead to valuation disputes, operational disruptions, and regulatory action. The RBI expects full system readiness and customer sensitization to avoid last-minute chaos.

What you must do

Who it affects

All commercial and co-operative banks, All India Financial Institutions, Non-Banking Financial Companies including Housing Finance Companies, Standalone Primary Dealers

❓ Common questions

What happens if we don't insert fallbacks in legacy US$ LIBOR contracts by June 30, 2023?

After June 30, 2023, US$ LIBOR and MIFOR will cease publication. Contracts without fallbacks will have no benchmark rate, leading to potential disputes, valuation issues, and regulatory non-compliance. RBI expects all fallbacks to be inserted well before the deadline.

Can we use synthetic LIBOR rates as a fallback for legacy contracts?

No. RBI explicitly advises not to rely on synthetic LIBOR rates as a substitute for fallbacks. Synthetic rates are not meant for new contracts and should not be used to avoid inserting proper fallback clauses referencing ARRs like SOFR or MMIFOR.

Are new transactions using MIFOR also banned?

Yes. MIFOR, which depends on US$ LIBOR, will cease publication after June 30, 2023. Banks must ensure no new transactions by themselves or their customers are priced using MIFOR. Only ARRs like SOFR or MMIFOR should be used.

RBI/2023-24/30 CO.FMRD.DIRD.01/14.02.001/2023-24 May 12, 2023 To The Chief Executive Officer/ Chairman/Managing Director, All Commercial and Co-operative Banks / All India Financial Institutions / Non-Banking Financial Companies including Housing Finance Companies and Standalone Primary Dealers Madam / Dear Sir LIBOR Transition Attention of banks/financial institutions (FIs) is drawn to the Reserve Bank advisory on “Roadmap for LIBOR Transition” dated July 08, 2021 wherein banks/FIs, inter-alia, were (i) encouraged to cease, and also encourage their customers to cease, entering into new financial contracts that reference London Interbank Offered Rate (LIBOR) as a benchmark and instead use any widely accepted Alternative Reference Rate (ARR), as soon as practicable and in any case by December 31, 2021 and (ii) urged to incorporate robust fallback clauses in all financial contracts that reference LIBOR and the maturity of which was after the announced cessation date of the LIBOR settings. 2. With the concerted efforts of banks/FIs as well as industry associations like the Indian Banks’ Association, a smooth transition with respect to LIBOR settings that have ceased to be published/become non-representative after December 31, 2021 has been achieved. The transition away from LIBOR was also facilitated by the continuing publication of US$ LIBOR settings in five tenors which provided a longer transition period particularly for the insertion of the fallback clauses in legacy financial contracts that reference LIBOR. New transactions are now predominantly undertaken using ARRs such as the Secured Overnight Financing Rate (SOFR) and the Modified Mumbai Interbank Forward Outright Rate (MMIFOR). At the same time, there have been instances of a few US$ LIBOR linked financial contracts undertaken/facilitated by banks/FIs after January 1, 2022. Also, while banks have reported that substantial progress has been made towards insertion of fallback clauses, the process is yet to be completed for all contracts where such fallbacks are required to be inserted. 3. After June 30, 2023, the publication of the remaining five US$ LIBOR settings will cease permanently. While certain synthetic LIBOR settings will continue to be published after June 30, 2023, the Financial Conduct Authority (FCA), UK, which regulates the LIBOR, has made it clear that these settings are not meant to be used in new financial contracts. The MIFOR, a domestic interest rate benchmark reliant on US$ LIBOR, will also cease to be published by Financial Benchmarks India Pvt. Ltd. (FBIL) after June 30, 2023. 4. Banks/FIs are advised to ensure that no new transaction undertaken by them or their customers rely on or are priced using the US$ LIBOR or the MIFOR. Banks/FIs are also advised to take all necessary steps to ensure insertion of fallbacks in all remaining legacy financial contracts that reference US$ LIBOR (including transactions that reference MIFOR). Fallbacks in such contracts should be inserted at the earliest so as to ensure that transition of any remaining US$ LIBOR-linked contracts is completed well before the deadline of end June 2023 and any disruptions due to a last-minute rush to insert fallbacks is avoided. Banks/FIs are advised not to rely on the availability of synthetic LIBOR rates as a substitute for fallbacks in legacy contracts. 5. Banks/FIs are expected to have developed the systems and processes to manage the complete transition away from LIBOR from July 1, 2023. Continued efforts in sensitising customers on the steps to be taken to manage the associated risks will enable a smooth completion of the final leg of the transition. 6. The Reserve Bank will continue to monitor the efforts of banks/FIs for ensuring a smooth transition from LIBOR. Yours sincerely, (Dimple Bhandia) Chief General Manager
