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
IOSCO has issued a document called “Principles for Financial Benchmarks” in 2013. As such it acted as an (unofficial/unelected) lawmaker. On 3 July 2023, the same IOSCO issued a “ Statement on Alternatives to USD Libor ”. The Statement looks like a tribunal judgement from a trial with no public hearing, no witness, and no defense right from a tribunal with no mandate to judge.

This creates a culpability by association to all non-SOFR benchmarks. The statement refers to a Review of Alternatives to USD Libor ; to my knowledge, the review itself is not available. The st
For more than a decade, collateral discounting as been the de facto standard for derivative valuation. The central technical concept of this approach is the expectation under a currency — but not collateral mechanism — dependent measure. That measure is denoted in part of the literature. This is the notation I used in my Multi-Curve Framework with Collateral paper in 2023. This is the paper that developed the details of the “collateral square” valuation, when the collateral is is an asset that can itself be used into a repo to obtain cash. The generic formula in that latter case is (originally described in formula 13 in the above paper). The measure X appears in the expectation and is central to the approach, based on replication. It mathematics, it is traditional to add some marker (like a tilde or a bar) on some symbols to indicate another object similar or generated from the first one. One symbol that I like is the "check", which I called when I was lecturing in fren
