The set of minutes may well have been written long before the date of publication. The MPC meeting this month was a dry-run of the new process of a three-day meeting (Thursday, Monday, Wednesday) followed by the preparation of the minutes to be released simultaneously with the policy announcement the next day, Thursday.
There is a small chance that the style of the minutes might have been adjusted slightly to make that schedule more feasible, i.e., making them a little shorter.
According to Societe Generale, a unanimous vote for unchanged policy is anticipated, with Weale and McCafferty yet again seeing the decision as finely balanced, a view they have held since the beginning of the year after reversing their December 2014 votes for a 25bp rate increase.
