Working groups on alternative reference rates (ARR)

A working group on alternative Norwegian krone reference rates was established by Norges Bank, in consultation with the financial industry, in early 2018.

Webinars in October 2020

The ARR working group has the pleasure of hosting two webinars to present the work that has been done so far this year. The webinars will be held on October 26 (in Norwegian) and 28 (in English).

Webinar 28 October: Establishing an Overnight Index Swap market in NOK

Selection of Nowa as an alternative reference rate

The working group published its recommendation of a reformed version of Nowa (pdf) (Norwegian Overnight Weighted Average) as the alternative reference rate at the end of September 2019. Norges Bank took over as administrator of Nowa on 1 January 2020 and has published new principles for calculating and publishing Nowa.

Use of Nowa as an alternative reference rate

The second phase of the group’s work on alternative reference rates is focusing on how to transition to using Nowa as an alternative reference rate. The working group invited other market participants into the work and divided the work into two sub-groups:

  1. Market standards and fallback solutions
  2. Establishing an OIS (Overnight Index Swap) market in NOK

Consultation reports published

The working group requests feedback from market participants by 2 November 2020. Email:

The original working group continues to be the main group for coordinating further work. The sub-groups will regularly update the main working group on their work. The mandates and lists of participants for the main working group and the two sub-groups are available here.
