A flood of fixed loans are transitioning to variable in the next 6 months.

With the inflationary effects people were finding it difficult to meet their repayments even with no flow on from the interest rate hikes.

When this hits when they start the variable rates, the banks will surely get hits to their balance sheets and even have liquidity problems and need the RBA to bail them out?

The RBA is already under water from this in Sept 2022:

Australia's central bank has revealed that it has lost A$44.9bn ($30bn; £26.3bn) on the bonds it bought as part of its efforts to support the country's economy during the pandemic.
The Reserve Bank of Australia's (RBA) deputy governor says that wiped out the bank's profit for the 2021-22 year, leaving a net loss of A$36.7bn.The bonds were accumulated under a A$300bn emergency stimulus programme.

However, the bank says the loss will not affect its normal operations. - https://www.bbc.com/news/business-62976794

It's really hard to make sense of this banking voodoo. The US Fed has made money out of thin air in many different ways.

"If any commercial entity had negative equity, assets would be insufficient to meet liabilities and therefore the company would not be a going concern," RBA deputy governor Michele Bullock said.

"Since it has the ability to create money, the Bank can continue to meet its obligations as they become due," she added.

Yes but 'creating money' especially to keep non productive assets afloat such as house loans on homes already built is going to be inflationary in effect.
Also the banks are lending less, their lending criteria has tightened massively resulting in lower profits.

So creating money is going to be inflationary especially if they're creating lots of it.

I find this is a conundrum and I can't see an easy solution to it.

Any thoughts?
