New APRA figures show the impact the Reserve Bank’s program of official interest rate increases has had on the Australian economy.
From the low of 0.10% in April 2022, official interest rates have increased by 425 basis points to 4.35%. Thankfully the Reserve Bank has this month kept rates steady, but the damage to the economy has already been done.
Since the March quarter of 2022, quarterly interest payments to the banks from the rest of the Australian economy went from $25.8 billion to $78.95 billion in March 2024. If we annualise these figures that means there has been a $212 billion increase in payments to the banks since official rates were increased.
Since that low of March 2022, each 25 basis point increase in the official interest rate increased banks’ annualised interest charges by around $12 billion. For comparison that is slightly more than the Australian government is budgeted to spend in this financial year on support for carers.
Over the same period, quarterly payments to the banks for home loans increased from $13.5 billion to $32.8 billion. The increase of $19.3 billion per quarter equates to just over $77 billion per annum. It also means that each 25 basis point increase in the official rate increases annualised interest charges on home loans by $4.5 billion per annum. Each 100-basis point increase increased the banks’ annualised interest charges on home loans by $18 billion.
