LIBOR Transition

With the increased expectation of some LIBORs discontinuation, the overnight benchmark changes and the increasing regulatory requirements related to benchmarks, a clear quantitative finance perspective on the impacts for benchmark-linked derivatives is becoming paramount.

Financial institution and the end-users of interest rate derivatives face many challenges when navigating through those changes and their impacts. The impacts are far reaching and relate to not only to the legal and operational issues but also to pricing, risk, modelling, validation and implementation in systems.

muRisQ Advisory has an extensive experience related to benchmarks and LIBOR transition. We have published on the subject since more than 2 years and have modeled and implemented the impacts in theory and in practice. We have been guest speaker at major academic and practitioner conferences in the last 18 months (see list at the bottom of the page).

We have created a set of introductory videos. Currently three of those videos are available on our Youtube channel. More videos will be added in the coming weeks.
  1. Benchmarks: tenor deposit and overnight (11:32)
  2. Why a transition? (15:01)
  3. Overnight transition: EFFR to SOFR and EONIA to ESTR (21:10)
  4. CCP big bang - EUR (6:32)
  5. CCP big bang - USD (21:42)
  6. IBOR fallback - overview (16:40)
  7. IBOR fallback - adjusted RFR (18:06)
  8. IBOR fallback - spread (17:11)
  9. IBOR fallback - value transfer (17:34)
The videos are at the introductory level for each subject. A lot more material is available for workshops and advisory engagements. The slides of the videos are available at:

Our libraries include the Fallback Transformers which allow to apply the exact fallback details to actual trades and portfolios. The transformation details include overnight composition, period offset, spread applicable, and discontinuation date. It is suitable for what-if analysis and risk management.

We help institutions in this regards in several ways:

Technical workshops

  • Public workshops. Recent presentations: WBS Interest Rate Reform conference (London, 4 March 2020), WBS Interest Rate Reform conference (Frankfurt, 26 March 2020). Planned presentation: QuantMinds (Amsterdam, 15 May 2020)
  • In-house tailor-made workshops on the quantitative finance impacts (valuation, risk, value transfer, model validation, new instruments). Typical agenda available on our training page.

Independent impact assessment

  • We use our own production grade systems, including Fallback Transformers, developed over the last years
  • Run existing different hypothesis for fallbacks and spreads on exiting portfolios
  • Analysis of re-papering and protocols impacts, cost of protocol signature
  • Analysis of value transfer on actual portfolios
  • Change of collateral/discounting: CCP big bang and bilateral. 

Implementation advisory

  • Support of quantitative analysis and risk groups in implementation (based on more than two years of internally developed research and systems)
  • OIS discounting, transition adjustments
  • New models development
  • Senior stakeholder support
  • New exchange traded products development
  • Reduction of existing exposure
  • Support for negotiation with counterparties
