Methodology and Survey Rules

Participation & presentation. This poll is open to anyone employed by a central bank, irrespective of department or standing in the central bank. A participant may take part only once, but can vote on as many or as few categories as they choose. The poll is anonymous: no mention will be made of names of individuals or their institutions in connection with this poll. An article summarising the aggregated findings of the poll will be sent to all participants. In this sense, the poll should be considered a reflection of how central bankers view providers of reserve management services. The poll is not designed to reflect volumes traded in any particular market and is therefore not necessarily a direct reflection of market share - voters could base their decisions on a variety of criteria, including pricing, liquidity provision, counterparty risk, speed of execution and reliability.

Aggregation & ranking. A participant’s votes will be weighted, with three points for a first place, two points for second and one for third. The tallied scores will then be aggregated and ordered by size to generate the ranking. Only categories with a sufficient number of votes are included in the final poll.
Qualification. When aggregating votes, we look to strip out what we consider to be invalid votes. These include:

  • People who clearly do not work at a central bank,
  • Multiple votes from the same person or IP address,
  • Proxy votes,
  • ‘Block votes’ from groups of people on the same desk at the same institution voting for the same firm, and
  • Votes that place the same firm indiscriminately throughout the poll.
