CBA sees Australian March CPI at 4.6%yr, trimmed mean at 3.5%yr, and calls for a 25bp RBA hike in May. Westpac warns the Iran energy shock will broaden through H2 2026.
Summary: CBA forecasts headline CPI rose 1.1% in March, lifting the annual rate to 4.6% CBA expects trimmed mean inflation of 0.9% for Q1 2026, pushing the annual rate to 3.5%, which would mark the third consecutive quarter at that pace or above CBA calls for a 25bp RBA rate rise in May to 4.35%, though flags the decision as line ball between inflation and growth risks Westpac estimates a 1.5% quarterly CPI gain, or 4.2% annually, with risks seen as balanced Westpac forecasts trimmed mean of 0.93% for Q1, lifting the annual rate to 3.5% from 3.4% Both banks attribute the bulk of the energy shock so far to auto fuel, with the Iran conflict having begun on 28 February Westpac warns the impact will broaden significantly in Q2 and through H2 2026, with trimmed mean seen hitting 1.0% per quarter and the annual rate peaking at 4.0% Two of Australia’s largest banks are forecasting a sharp rise in consumer prices for the March quarter and warning that the energy shock from the Iran war is only beginning to filter through the economy, with both lining up behind a potential rate rise at the Reserve Bank of Australia’s May board meeting. Commonwealth Bank of Australia expects headline inflation to have risen 1.1% in March alone, pushing the annual rate to 4.6%.

Notably, that would mark the third consecutive quarter in which the trimmed mean has risen by 0.9% or more, a streak that CBA argues justifies a response from the central bank. The lender is explicitly calling for the RBA to raise the cash rate by 25 basis points at its 4-5 May meeting, taking it to 4.35%.
