On June 8, ISDA and UK Finance jointly wrote to HM Revenue & Customs (HMRC) to respond to their consultation on tax impacts arising from the withdrawal of LIBOR. The associations welcomed the consultation and the draft guidance included on the subject. As noted in previous correspondence with HMRC, certain tax omissions and certain tax aspects could potentially have material implications and/or cause uncertainties, which may serve as a barrier to secure the consent needed from derivatives counterparties to make contract amendments and could risk obstructing the broader benchmark reform transition project.
