Macquarie continues to make market share gains, attracting an outsized share of household deposits. Few can keep up with them, some are leaking rather badly

The December results are in (from APRA) and that shows Macquarie's appetite for household deposits is undiminished.

Macbank has a market share of 5.9% overall, but in December it won 14.7% of all new household deposits.

That puts its market share grab in December larger than NAB's 13.4%, and up there with Westpac's 18.8% share in the month.

And it dwarfed ANZ's miserable 7.1% December share, an embarrassingly big retreat from their embedded 11.3% market share. Two years ago, they had an 11.8% market share.

Challenger banks are suffering market share fades as well. Two years ago, all banks other than the top five had a 23.0% share. Now they have a 21.7% share, but in December alone they won only 14.7%.

It is getting serious for all banks - except perhaps Commbank.

The market leader had 26.6% market share two year ago and that is the same as in December 2025. In the month of December, they won 31.2% of household deposits, one of the few banks other than Macquarie (and ING) to make gains.
