A Quant Perspective on IBOR Fallback Proposals

A month ago, ISDA launched a consultation on IBOR fallbacks. The question of the fallback in case of a benchmark discontinuation has obviously legal background. Parties to the derivatives contracts have to ask themselves: What is the meaning of what I signed? Is it really what I want? The answer to the last question is probably: "no, it is not what I want!" This is why most of the derivatives users agree that a change in the fallback language is required.

Once you are convinced that what you have is not what you want, you have to review the alternatives. I have published a note with a personal review of the alternatives from a "quant" perspective. Even if personally I would prefer to the called it a "qualitative analysis" as before assessing the quantities associated to the alternatives, you have to check their qualities against a set of qualitative criteria.

The note gives some background for the Season 2 of Game of Benchmarks: The Questions!

The note is available on SSRN:

A Quant Perspective on IBOR Fallback Proposals

Abstract

With the increased expectation of some IBORs discontinuation and the increasing regulatory requirements related to benchmarks, a more robust fallback provision for benchmark-linked derivatives is becoming paramount for the interest rate market. Several options for such a fallback have been proposed. This note describes and analyses some of those options. The focus is on the quantitative finance impacts. None of the options that have been proposed fits all of the criteria for a good fallback provision. It appears that some of the options that have gained traction failed even the achievability criterion. The note concludes with the author's personal preference.

Question 1: Question related to Option 3: Compounded Setting in Arrears Rate

Multi-curve framework book: new edition in progress

Image
Subject: Interest Rate Modelling in the Multi-curve Framework: Foundations, Evolution, and Implementation It has been more than 10 years since I wrote the first edition of the multi-curve framework book. What happened in those 10 years? Why did it take me so long to start a new version? It took me roughly 10 years to write the first edition. The reason it took so long at that time, was that I did not know that I was writing it! I thought I was writing a couple of pages on an obscured and theoretical idea that there was not a `` one curve to rule them all '' but multiple curves. It turned out that it became the actual practice for very clear and important reasons. That was the excuse for the first edition, what is the excuse for the second edition? Since the first edition, many things happen, in particular: March 2015: BCBS - IOSCO: margin requirements for non-centrally cleared derivatives and mandatory variation margin July 2017: The future of LIBOR -- actually it

Rigged: part 1 - Will there be a part 2?

Image
I have been reading book “Rigged: The Incredible True Story of the Whistleblowers Jailed after Exposing the Rotten Heart of the Financial” (Andy Verity, Flint, June 2023) for some time. It was published several month ago, but I just finished it. To my defence, I have to say that I don’t feel comfortable reading fiction where the “bad guys” are systematically winning by cheating. The book is the story of the miscarriage of justice done in the LIBOR manipulation story. The book content did not surprise me. For anybody having worked on a (swap) trading desk, it is clear that what was described by the accusation was impossible. It is not possible for some middle level trader to create a multi-year, multi-desk, multi-bank international conspiracy over open lines, broker lines, on open offices etc. without all around them, including compliance and senior management to be fully aware of what is going on. Moreover the regulators cannot be ignorant of the situation, except pleading complete in

Pertes de la BNB: c’était prévu et nous payons!

La BNB: 3 milliards de pertes et encore 6 milliards à venir. Voir par example l’article de l’Echo: La perte de la BNB a dépassé 3 milliards d'euros en 2023 . 1) C’était le but! C’était prévu! 2) Quis custodiet ipsos custodes? 3) Quatrième pouvoir? 1) C’était le but! Les achats d’obligations gouvernementales avaient pour but de diminuer le coût des emprunts pour les États concernés. Il y a bien sur la fiction que ce n’est pas du financement des états parce que les obligations sont achetées dans le marché secondaire aux banques commerciales. Une fiction car les banques commerciales; achètent ces obligations sur le marché primaire à un prix surévalué uniquement parce qu’elles savent qu’elles peuvent les revendre à un prix encore plus surévalué aux banques centrales. C’est d’une certaine façon un “pump and dump”. Si ce n’est que dans le “pump” le seul pompage est par les banque centrales et le reste sait que ce pump n’intervient que pour soutenir un actif de moindre qualité. Et
