So the major banks are going to have to raise about $20 billion and probably increase borrowing levels by up to 60 basis points - depending on who you listen to.
That's going to have consequences for consumers and the economy in the form of higher interest rates, although not as big as previously thought due to the concessions in the final decision released this week.
In allowing some of the increase in capital to come from preference shares rather than common equity and retained earnings, the central bank has opened up a new product for New Zealand investors to tap into.
There's plenty of money sloshing around looking for a home and it would be good if the New Zealand Superannuation Fund, ACC and KiwiSaver funds fill their boots with a decent chunk of the $9 billion that could be raised through preference shares.
That way, more New Zealanders could share some of those huge profits the Aussie banks make from these shores each year.
