Prior to BBSW publication on 29th October, ASX was notified of incorrect quotes submitted for the 4-month tenor at the 8:45am and 9:15am snapshot times. As the affected quotes formed part of the NBBO used in the 4-month BBSW calculation, ASX re-calculated the NBBO rate manually for 4-month BBSW using correct quotes only. This resulted in a "manual" publication method recorded for the 4-month tenor and a rate of 5.0175% as published without issue at 10:28am on 29th October.
