It isn’t possible to simply abandon these benchmarks and parties to contracts have continued to use the existing ones, well-known warts and all, because they need something.

The International Organization of Securities Commissioners (IOSCO) is the latest body to weigh in on what to do. We were invited to comment on it. You can read what we said here. We used this as an opportunity to elaborate on our earlier analysis of the Wheatley Review findings. We make seven key points:

This offers a number of advantages, not the least of which being its robustness (though not immunity) to fraud and manipulation. Where a transactions basis is not viable, the second-best alternative is to use committed quotes. The final option, uncommitted quotes of the type used for LIBOR, should not be adopted.
