We have noted separately the growth in household bank account balances.
But somewhat overlooked is the amount New Zealand households have stashed in savings accounts. It's a lot, and it's 'lazy money.'
The data revealing this is published monthly by the Reserve Bank in their S40 series. The latest data is to January this year.
Calling the savings account balances 'lazy' is only part of the story. And it isn't the 'laziest' funds we have on hand. Those are in our current account balances, earning nothing*.

That is $25+ billion extra sitting in these accounts since the start of the pandemic, free money for banks. Yes, we do need ready funds for everyday needs, liquidity for emergencies. But the pandemic has raised the stakes, shifted us into a very risk-averse mode.
There are also household term deposit accounts, and these are another $83 bln, earning some interest at least.

And then there is another $80 bln in "savings accounts," put there on purpose, but earning very little anymore.

Being risk-averse is understandable in uncertain times. Holding higher liquidity in uncertain times is understandable too.
But are we over-doing it?
Each of us has to make a judgment for our own situation. Our collective judgments reveal considerable financial fear.
But what we can do is quantify what it is costing us.
If there is $25 bln 'excess' in transaction accounts, and $80 bln in savings accounts earning 0.3% pa, that means $105 bln is earning $240 mln per year.
If all this was in a nine month term deposit account, it would be earning about 2% from the main banks, (or up to 2.25% at Heartland or Rabobank). That too may not seem like much, but it would amount to $2.1 bln per year. So we are leaving $1.86 bln on the table - and our banks are secretly thanking you for this gift!
$1.86 bln isn't minor for banks. They collectively make $6.245 bln in after tax profits. To give them their due, that is after paying $3.08 bln in tax to the Treasury. So the $1.86 bln we are leaving for them by not making our cash savings work harder added +25% to their profits! Their shareholders thank us.
The final context is how much of this is "per household". Stats NZ says there are just over 1.9 mln households (1,908,700 as at December 31, 2021). Of course the $105 bln isn't evenly held by each of those households. But the average is a higher level than you may have assumed - $69,277/household. In addition, we have $27.3 bln in our core transaction account balances, plus that $83.4 bln in interest-earning term deposits. These total $110 bln. So the $105 bln 'excess' held in liquidity is a measure of risk aversion and financial fear, money held close for a concern that 2022 holds clear and present dangers for households. Or we have just gotten lazy.
