CPILW rose significantly to 1.5% in April from 0.8% in March. The official CPIH measure of inflation also rose significantly to 1.6% from 1.0% the previous month. The gap between the official measure and the measure using lockdown weights has remained small but positive. This contrasts with the months prior to December 2020, when CPIH was less than CPILW, indicating that the official measure tended to understate inflation in that period. Since December 2020 the two measures have moved closely together indicating that the official measure CPIH is robust to any expenditure shifts resulting from the Pandemic.
