If Australian banks were banned from borrowing foreign funds as bank bonds, then they would have around 25% less funding...which would contract funds available to lend to Aussies for housing.
Please clarify how borrowing foreign funds doesn't expand our money supply and allow us to pay more AUDs for houses.
It creates M3 not AUD there is a short term demand for AUD in the thick of the transaction but in the end like all credit transactions the result is AUD used for settlement but at the end of the transaction the same AUD existed as before with more credit and debts through the system. In this case the credit is to foreign creditor.
i.e. someone ends up with a deposit account with AUD in it usually but in this case it will be $US and be in an overseas account. No AUD was created only used to settle the transaction.
Anyway an example:
Customer A wants to borrow 1 million dollars AUD to buy a house, assuming the bank has no spare funds but sufficient capital adequacy to make the loan.
The bank borrows US900,000.
It now has on its books
US900,000.00 liability
US900,000.00 in cash asset
The bank now needs to convert this to AUD so they buy futures of $US to allow them to pay this debt out a fixed rate as it comes due and carry the $US debt along with the hedge result on the balance sheet but convert the physical $US into AUD.
They take the US900,000.00 and convert them to AUD1,000,000.00. Their is a short term demand for AUD here, but this is only required for the transaction, later the AUD gets back out into the system to be used again to create more M3.
They then "deposit" this AUD1,000,000.00 into the seller of the houses nominated account assuming this is with another bank it is likely their will be a demand for this AUD soon enough, i.e. they will pay this AUD to the other bank. Most of these transfers will be electronic rather than physical but nonetheless by this time the requirement for physical AUD has passed. The bank has no AUD, no one has any AUD but the creditor has US900k in his account and the borrower has a 1million AUD debt in his account.
The AUD have travelled off to create more M# elsewhere. The $US are likely to find their way back to the US as well, or not, but typically if a country prints more of their currency even only to spend offshore it finds its way back.
So while AUD is used for the transaction none is created. It does create more Australian M3 however broad money but in the same way as it is created (M3) it can be undone. The US creditor can ask for their funds back for example. This means the Australian lender has to find alternate funds to fill the breech. This is what Keen is concerned about is our level of M3 v base money sustainable? Is our debt per person sustainable?
So yes it allows us to pay more AUD to buy houses but it does not create more AUD. It creates more M3, and yes M3 effects inflation generally not just in houses, but in Australia it appears certain asset classes are where our credit is concentrated residential housing being the primary one.
To be clear about M3 measures the increase in Australian M3 is only on the sellers account, the US creditor is not in our M3 but will count toward their own M2. However the punter who has just sold his house for 1 million AUD when before he only had a house is contributing to our M3. This is the feedback loop I mentioned in my earlier posts. The more the asset rises the more funds available to fuel further price increases.
